The old man and the sea

A wonderful and inspiring adaptation of Ernest Hemingway's story of the same title.
Aleksandr Petrov, the one man Army behind this classic adaptation, has achieved so many well deserved prestigious awards for this once in a life time movie that can be made.
Recipient of the Academy Award for Best Short Animated Film in 2000, The Old Man and the Sea tells the story of an elderly fisherman.


Santiago is a proud man but he no longer has the energy that he once had.
He has not caught a single fish in weeks.
One morning, he decides to go offshore and to stay at sea until he catches something to prove to himself that he is still capable.
Thus begins a relentless battle between an old man and an enormous fish that may end up being the catch of his life. 
Extract from the 1958 film directed by John Sturges and adapted by Peter Viertel with Spencer Tracy

We’re mapping wartime shipwrecks to explore the past – and help develop green energy projects

From The Conversation by Michael Roberts

Wartime shipwrecks such as the USS Juneau – recently discovered in the Pacific Ocean by philanthropist Paul Allen and his team – are of great interest to both military historians and the general public.
The USS Juneau was holed by a Japanese torpedo off the Solomon Islands in November 1942, and sank in more than 13,000 feet of water with the loss of 687 lives.
Its discovery offers a hugely valuable insight into the fate of both the ship and its crew.

Many such wrecks lie in extremely deep, relatively clear waters and are the legacy of naval battles fought far out to sea.
But some of the technologies and methods that are being used to locate and identify such sites are now being employed by scientists in shallower, sediment-rich UK waters for similar – and very different – purposes.

During both world wars, Britain relied heavily on shipping convoys to supply the nation via well-established maritime routes into major ports such as Liverpool, Cardiff and Bristol.
But these busy marine “corridors” were also well known to enemy forces, and losses due to German U-boat attacks, mines and collisions due to enforced “blackouts” in the Irish Sea were significant throughout both conflicts.
There are more than 200 such wreck sites around Wales and many have yet to be examined in any great detail.

Since 2014, via the SEACAMS project funded by the Wales European Funding Office (WEFO), scientists from the School of Ocean Sciences at Bangor University have been using their research vessel Prince Madog – which is equipped with state-of-the-art multibeam sonar technology – to locate and survey vessels from both world wars.
And in the Irish Sea alone, there are plenty to choose from.


How it works

The modern multibeam sonar systems on the Prince Madog generate very high resolution, three-dimensional models of the seafloor as the research vessel moves through the water over it.
Depending on conditions and the specific systems used, these models can allow surveyors and scientists to identify objects at near centimetre scale.
In water depths of 100 metres, typically found in the Irish Sea, researchers are generating models and images of wrecks that can help marine archaeologists to confirm their identity and even provide evidence of their demise.
So far, more than 70 individual sites have been studied and it’s hoped that the project will survey around 100 new wreck sites this year.

While these wartime relics can provide valuable information to historians and archaeologists, they may also help lead to the birth of a new industry.
The data being collected are providing scientists with unique insights into how these wrecks influence physical and biological processes in the ocean and this information is now being used to support the ambitions of the marine renewable energy (MRE) sector via research and development projects with developers such as Minesto in North Wales and Wave Hub in Pembrokeshire.

A number of MRE projects –– some being planned, some already underway – aim to capitalise on Wales’ excellent wave and tidal resources to create a sustainable energy supply.
To assist in this, scientists at Bangor are now using shipwrecks as models and laboratories for predicting what will happen when key MRE-related infrastructure, such as foundations, turbines and cabling, are placed on the seabed at various locations.

Wrecks provide information on how the tide and currents have removed or deposited sediments and how the presence of these structures on the seabed have influenced these processes over time.
Researchers are also looking at how these structures can act as artificial reefs, potentially increasing the number of fish in an area and attracting whales, dolphins and diving birds.
Through repeat sonar surveys, the research is also examining how different wrecks are degrading and how these vessels may ultimately pose a risk of pollution to nearby coastlines.

The data gathered will be hugely useful to those behind MRE projects, allowing them to better predict how green energy infrastructure will effect – and be affected by – their undersea locations.

Forgotten Wrecks of the First World War is a Heritage Lottery funded project that will educate about the sometime forgotten stories and tragedies beneath our waters.

Looking deep

As with the surveys underway in the South Pacific, such as the one that discovered the USS Juneau, the research being conducted in the Irish Sea is also driven by a desire to improve our understanding of past conflicts.

The Heritage Lottery funded project, Commemorating the Forgotten U-boat War around the Welsh Coast, 1914-18, for example, is being led by the Royal Commission on the Ancient and Historical Monuments in Wales in partnership with Bangor University and the Nautical Archaeology Society.
It aims to highlight the fact that not all World War I battles and losses occurred along the Western Front – indeed, many raged within sight and sound of the UK coastline.

They were also truly international incidents.
Many of the ships sunk were British, French, Irish, Norwegian, Portuguese and Russian – with crews from all over the world.
Many German vessels were sunk, too.


Royal Navy Pinnace 704 was built in 1915 and was 50 feet long.
Pinnances were jack-of-all-trades small vessels, often used to carry personnel or light stores within harbours, between ships, or from ship to shore.
Sometimes they were also used as gunboats.
RN Pinnace 704 was stationed in Royal Clarence Victualling yard in Gosport during the First World War; she was still there in 1947.
By the 1970s, 704 had been disposed of and come to rest in Forton Lake, Gosport, where her structure has deteriorated dramatically.
All that can be seen of 704 today are a few sections of her lower hull and her prominent boiler.

The surveys are also solving scores of mysteries.
Of the shipwreck sites in the Irish Sea examined so far, we have found that 40% of the vessels have been incorrectly identified on maps and charts.
Using the detailed models produced by the sonar technology – as well as naval archives, shipyard records and a little detective work – we hopefully can ensure these mistakes are corrected and that we know exactly what was sunk where.
This will give us a far clearer picture of what now lies beneath the waves – and what such wrecks can tell us about the turbulent past of these oceans.

Cyber Security at sea: the real threats



From Maritime Executive by David Rider


The maritime cyber security landscape is a confusing place.
On the one hand, you have commercial providers suggesting the risks of everything from a hostile attack on ship’s systems which allows the vessel to be remotely controlled by pirates and direct it to a port of their choice, or causing a catastrophic navigation errors, a phishing attack or ransomware on the Master’s PC.
While on the other, you have sensible people who point out that this notion is nonsense due to the number of fail safes and manual overrides and controls in place.

Then there are calmer voices still, who point out that the most likely threat is actually to the servers inside your head office, or a man in the middle attack on your company’s bank accounts.

Recognizing the threats

So what are the real, documented, current threats to the shipping industry from cyber criminals? Here, we hope to offer some genuine guidance without scaremongering.
We’re not trying to sell you anything.
We’re just trying to make sure you know what the risk of simply doing nothing is.

Much has been made of the threat to vessels on the water from hackers.
However, there is only limited available credible evidence to support claims of hacks at sea.
Rather, the real threats on the water come from a lack of crew training and awareness and a culture which turns a blind eye to crew using their own devices at work (Bring Your Own Device, or BYOD) and plugging them into ship systems to charge them, thereby possibly releasing a malware they may have been inadvertently carrying onto the vessel.

 ICS, BIMCO and Singapore MPA Cyber Security Onboard Ships Awareness Poster developed to complement the industry Guidelines on Cyber Security Onboard Ships.
The poster is designed to raise awareness amongst onboard personnel regarding the basic steps that can be taken to contribute to effective maritime cyber risk management and the implementation of protection measures by Companies.

Maritime cyber security survey results

In 2017, I.H.S. Fairplay conducted a maritime cyber security survey, to which 284 people responded.
34 percent of them said that their company had experienced a cyber attack in the previous 12 months.
Of those attacks, the majority were ransomware and phishing incidents; exactly the same sort of incidents affecting companies everywhere, and not at all specific to the maritime world.

The good news is that only 30 percent of those responding to the survey had no appointed information security manager or department, meaning that the majority of companies have a resource able to respond and mitigate any attack.

However, the survey did reveal that there are still a lot of employees who have not received cyber awareness training of any kind, which means the shipping industry must try harder, for its own security.

Additionally, only 66 percent of those questioned said that their company had an IT security policy, which is a serious cause for concern; IT security cannot be approached on an ad hoc, incident by incident basis.
It’s the security equivalent of plugging holes in a hull with cardboard.

To underline that, 47 percent of those questioned believed that their organization’s biggest cyber vulnerability was the staff.
Hardly a glowing endorsement but, if you don’t train your staff to be aware of threats, it’s not surprising.

Mitigating the risk – train your staff

Imagine you’re in charge of a company.
You trust your staff to do everything.
Except, it seems, ensure your bank accounts aren’t handed over to cyber criminals or that your network is exposed to ransomware or malicious attack.

It would seem to be a rather curious way to run a company.

The key to mitigating cyber crime is training.
Yes, you can put posters up; send company memoranda out; promote industry guidelines.
But how many of your staff take those in?
A robust workplace IT security policy is the first step, but that can only work when also supported by a training course where employees can see the risks through demonstrations, simulations and good teaching.

There are very simple changes that any company can make to ensure better security in the workplace.
From enforcing a zero tolerance on BYOD, which is often disliked by the crew, to separating crew and administrative or operational networks, blanking unused USB ports and requiring monitors be turned away from public view to prevent “shoulder surfing” and a rule that all computers go into secure sleep mode when left unattended.

For staff dealing with accounts, additional rules may be required to ensure the risks of phishing and social engineering (whale attack) are reduced.

You don’t think your company is at risk?
In November 2016, Europe’s largest manufacturer or wires and electrical cables, Leoni AG, lost £34 million in a whale attack, when cyber criminals tricked finance staff into transferring money to the wrong bank account.
£34 million.
Lost… That should be read out to every board of directors.

And similar attacks take place every week.

In the last six months, the shipping industry has seen several incidents in the sector, ranging from a data breach at Clarksons through to the damage done to Maersk by the WannaCry NotPetya variant sabotage/ransomware incident, which the company believes cost it as much as $300 million.

These are some of the reasons for the creation of the Maritime Cyber Alliance, a project created by CSO Alliance in partnership with Airbus Defence & Space.
The aim is simple: connect maritime and oil and gas chief information security officers via a secure, private platform, allow verified cyber intrusions to be reported anonymously and provide members with threat alerts and tools to analyze malware and prevent attacks as well as offering workshops to promote best practice in the industry and listen to concerns.

February saw the Alliance participate in four workshops across the U.K., in Aberdeen for the offshore industry; Edinburgh for the ports community and Glasgow for ship management.
Guest speakers included Kewal Rai, Policy Adviser for Cyber Security with the Department of Transport, Sergeant David Sanderson from Hampshire Police, Vic Start, Thomas de Menthiere and Jean Baptiste Lopez of Airbus, among others.
Among the concerns raised by attendees were questions on mitigation of attacks, the impact of E.U.’s General Data Protection Regulation (GDPR) on the U.K. and how Airbus was delivering its solutions to users of the site.

The Alliance is already gathering detailed cyber crime incident reports from industry.
We’ve seen an examples from shipowners who lost two days’ hire due to malware contamination via a USB stick, invoice fraud in the port, superyacht and ship broker sectors.
The latter saw a ship broker’s systems compromised by criminals who altered payment details to steal £500,000.

Luckily, in that case, the company’s quick reaction, a court order and a rapid forensic investigation ensured they recovered the missing funds.
We are starting to see multiple attempts of invoice fraud using privileged information, which means a vendor’s company accounts have been compromised.
The timely sharing and analysis of information will grow with the increased cyber crime report data flow via the Cyber Alliance’s crime reporting servers, based in Iceland in order to ensure anonymity.
The solution, of course, is to ensure your company requires multiple sign-offs for any payments over a certain amount and pick up the phone to verify and vendor bank account changes.
The risk of getting it wrong could bankrupt you.

There’s clearly a need for industry to take the lead on protection and, hopefully, the Maritime Cyber Alliance will enable that.
Further workshops, which are all free to attend, are planned for the coming months.


Regulatory compliance

The next major hurdle facing companies around the globe comes in the shape of the GDPR, which comes in to force in May 2018.
It will affect companies in every sector, but the maritime industry in particular, given its global reach.

In essence, the GDPR is the first data protection measure to affect the entire world.
If your company holds or processes the personal data of E.U. citizens, people working for E.U.
entities or trading with the E.U., then you’re affected and will need to ensure that you’re compliant with the new regulations.
Failure to do so will result in huge fines.
GDPR’s definition of “personal data” is far broader than previous regulations, meaning that any information which can be used to identify an individual falls under it.

The new regulation introduces Privacy Impact Assessments (PIAs), which means that companies will be required to conducts PIAs wherever privacy breach risks are high in order to minimize risk to data subjects.
Many companies may have to hire data protection officers in order to ensure compliance, while those companies dealing with EU crews will also want to take note of their liabilities in this regard.

The good news is that GDPR will also bring in common data breach protection notification requirements, so companies will be forced to report any breach of their systems within 72 hours, thus ensuring industry awareness and a better response time to potential vulnerabilities.
This, in itself, may require staff training and is yet another aspect of GDPR companies need to be aware of.

For companies doing business in the E.U., which covers a vast swathe of the maritime industry, the NIS Directive covering network and information security also comes in to force in May 2018.
In the U.K., the government has announced that organizations working in critical services like energy, transport, water and health can be fined up to £17 million as a “last resort” if they fail to demonstrate that their cyber security systems are equipped against attacks.

The NIS Directive requires organizations to have the right staff in place and the proper software to mitigate cyber attack and intrusion.
Private and public companies in each sector will be evaluated by regulators who will vet everything from infrastructure and issue fines for firms who fail.

“Network and information systems give critical support to everyday activities, so it is absolutely vital that they are as secure as possible,” said Ciaran Martin, U.K. National Cyber Security Centre CEO, in a statement.

Ultimately, the new regulations will be of benefit to everyone, but ensuring your company meets the right standards will be crucial.
The days where maritime cyber security amounted to just making sure you turned the office PC off are long gone.
Today, cyber security demands board room level attention as well as vigilance from all employees, be they in head office or out on the water.

The cartographers who put water where it didn’t belong

Cartographer Antonio Zatta included the Lake de Fonte on this 1776 map.

From AtlasObscura by Jessica Leigh Hester

From a distance, European mapmakers documenting North America often perpetuated strategic myths of oceans, lakes, and rivers.

To hear Admiral Bartholomew de Fonte tell it, his voyage was full of serendipity and promise.
In a 1708 edition of the English periodical The Monthly Miscellany or Memoirs for the Curious, de Fonte recounted a journey, some five decades prior, “to find out if there was any North West Passage from the Atlantick Ocean into the South and Tartarian Sea.”
He had shoved off from Lima, he wrote, and navigated to the present-day Pacific Northwest, where he entered an intricate system of watery arteries that beckoned him inland.

He chronicled one fortuitous scene after another.
Nudged along by gentle wind, he floated into a lake he christened Lake de Fonte.
It was 60 fathom deep (roughly 360 feet), and “abounds with excellent cod and ling, very large and well fed.”
The water was also speckled with islands thick with cherries, strawberries, and wild currants.
The land was shaggy with “shrubby Woods” and moss, which fattened herds of moose.

His tales were full of plenty—lush land, well-stocked seas—and they were also totally apocryphal.
There’s no proof of the voyage, or of the character of de Fonte himself.
The whole saga, excerpted in the historian Glyndwr Williams’s book, Voyages of Delusion: The Quest for the Northwest Passage, was later attributed to the magazine’s editor.

Cartographer Antonio Zatta included the Lake de Fonte on this 1776 map.

When plotting out their maps of North America, many 18th-century European cartographers relied on accounts that drifted across their desks.
These were a collage of nautical references, local lore, missionary dispatches, and more.
Since it wasn’t always possible to fact-check these observations, even maps by the most conscientious makers could be sprinkled with errors.
Some of these incorrect annotations were aspirational—and many of them had to do with waterways.

Say that de Fonte had indeed, as he claimed, passed a ship that had sailed inland from Boston.
That would have been proof of a viable route through the Northwest Passage, which would have been a major boon to British and French traders.
This type of passageway, or other interior waterways like it, would have been so convenient, in fact, that a number of cartographers seemed to will it into being by putting it on paper.

Kevin James Brown, the founder of Geographicus Antique Maps, traces the notion of an inland sea to the 1500s, when the Italian navigator Giovanni da Verrazzano spotted the sounds abutting North Carolina’s Outer Banks and assumed he was looking at an ocean.
This sea dried up from maps within a few centuries—just in time to make way for an inlet or strait described in another (potentially fabricated) narrative of the explorer Juan de Fuca’s voyage.
The Sea of the West (or Mer de la Ouest), a later and larger speculative sea occupying much of the present-day West Coast, gained traction in the work of the cartographers Guillaume de l’Isle and Philippe Buache.

The massive Sea of the West takes up a sizable portion of this 1762 map by Jean Janvier.

By the early 18th century, writes Brown, cartographers were combating the problem of patchwork knowledge by plugging in best guesses—drawn from science and geographic patterns—“to fill in blank spaces when little else was known.”
The Sea of the West “is the perfect example,” Brown writes.
“Though a salt water inlet from the Pacific had long been speculated upon and hoped for, Buache and de l’Isle embraced the theory because it supported both the ambitions of the French crown in the New World and the theoretical geographic theory that Buache was developing.”
It was a speculative addition—and a strategic one.

Ditto the the River of the West, an apocryphal route that meandered from the middle of the continent to its western edge.
Two different potential routes are suggested on this 1794 double-hemisphere map by Samuel Dunn.

Samuel Dunn’s 1794 map of the world is ambitious and vast—and includes two different routes for the apocryphal River of the West.

These features disappeared from maps soon after, as expeditions got an in-person look at the geography and dismissed the more fanciful additions.
Now, they linger as reminders that maps don’t only recount geographic traits, but also the aspirations (politically, economically, and otherwise) of the people who plot them.

Bigger is not better for ocean conservation

Should the oceans be managed by citizens or financial markets ?

From NYTimes by Luiz A. Rocha

I have spent my entire life pushing for new protected areas in the world’s oceans.
But a disturbing trend has convinced me that we’re protecting very little of real importance with our current approach.

From Hawaii to Brazil to Britain, the establishment of large marine protected areas, thousands of square miles in size, is on the rise.
These areas are set aside by governments to protect fisheries and ecosystems; human activities within them generally are managed or restricted.
While these vast expanses of open ocean are important, their protection should not come before coastal waters are secured.
But in some cases, that’s what is happening.


MPA's
According to the UN's World Database on Protected Areas, which records marine protected areas (MPAs) submitted by countries, more than 15,600 MPAs protect more than 25 million square kilometers (almost 9.7 million square miles) of ocean.
In other words, nearly 7 percent of the ocean, an area the size of North America, is under some kind of protection.
A more conservative assessment of the global picture, by the Marine Conservation Institute and its Atlas of Marine Protection, shows only 3.66 percent of the ocean managed in true MPAs.

 Visual aid: it's 2% of the light blue area in this map that the article is talking about.

Near-shore waters have a greater diversity of species and face more immediate threats from energy extraction, tourism, development, habitat degradation and overfishing.
If we leave these places at risk, we’re not really accomplishing the goal of protecting the seas.

As the United States undertakes an alarming rollback in environmental protections, other countries are making news by safeguarding remote expanses in efforts to meet or even surpass commitments to the United Nations to protect 10 percent of marine areas by 2020.
We should not continue applauding countries that are simply drawing a line around relatively empty waters where protections are neither essential nor most effective to meet a target.
Instead we need to do the harder work of safeguarding the most threatened regions of the ocean — the coastlines — even if they’re smaller.

Last year, for example, Chile created a marine protected area that stretched 278,000 square miles around Easter Island.
It is impressive in scope, but the protected area still allows fishing in the coastal waters that are the habitat of unique species requiring the most protection.
This misguided action was praised as a win for marine conservation.

Protecting coastal areas is critical because they are where most of the ocean’s biodiversity occurs.
For example, coral reefs — which are a coastal habitat — cover less than one-tenth of one percent of the ocean floor, but are home to 25 percent of all marine species.

Mexico, Palau, Britain and, most recently, the Seychelles have also set aside protected areas in their waters but have allowed some fishing to continue as before.
And this week, my native Brazil announced that it would establishtwo major protected areas in the Atlantic Ocean.

Those areas — totaling almost 350,000 square miles — will encompass islands some 600 miles offshore and increase Brazil’s protected areas to nearly 25 percent of its waters from about 1.5 percent now.
The Ministry of the Environment is creating a circle of protection 400 miles in diameter around those islands without actually protecting much of anything.
Fishing, both recreational and commercial, will still be allowed within most of those areas, and only a small portion of the coastal habitats surrounding the islands, the most critical to safeguard, will actually be protected from fishing, mining and oil and gas exploration.

 Location of the no-take zones in the new Brazilian MPAs superimposed to the footprint of industrial fisheries.
No dots=no fishing; blue dots=low fishing; green=medium low; yellow=medium; orange=medium high; red=high fishing.
How these MPAs will protect fish ?

All the while, dozens of other proposals for protected zones in coastal Brazil (including one of my own), some as small as one square mile, have gone nowhere.

The United States has pursued this “just add water” approach, too.
In 2006, President George W. Bush created the Papahanaumokuakea Marine National Monument, covering 140,000 square miles around the northwestern Hawaiian Islands.
By all measures, this was a great move because it fully protected all coral reefs in the monument.
Ten years later, President Barack Obama expanded it into the open ocean, more than quadrupling its size.
This action was extolled for providing critical protection for coral reefs, but in reality the reefs had been safe since President Bush designated the original area.

Some argue that these open-ocean protected areas harbor hundreds of oceangoing species.
While that’s true, even the most effectively enforced of these areas fail to fully protect species like tuna, whose cruising speed of 10 miles an hour means that they can cross a protected area in mere days.
The expansion of Papahanaumokuakea, for example, has not affected Hawaii’s annual yield of open-ocean tuna catches.

By setting aside large protected areas in parts of the ocean that are not heavily fished, countries have shrugged off their international obligation to pursue science-based conservation and protect places where threatened species spawn or feed.
Instead, they have given the public a false sense of accomplishment.

Southern Ocean Sanctuaries: Protecting the World’s Final Ocean Frontier
The Southern Ocean—the waters surrounding Antarctica—is the one of the last untouched wilderness areas on the planet.
But a warming climate and increased fishing pressures put this vast area and its iconic species such as penguins, whales, and seals at risk.
The solution: fulfilling the promise by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) to create a network of marine protected areas that will safeguard the world’s final ocean frontier—before it’s too late.

Where do we go from here?
First, countries should create protected areas only where they can make a real difference in safeguarding marine life: highly diverse coastal habitats, spawning areas and feeding locales.
This year, for example, Honduras announced the creation of a critically important protected area in Tela Bay in the Caribbean.
Although it’s very small in comparison to other reserves — only some 300 square miles — it is a huge victory for marine conservation.
The government devised a solution that will reduce unsustainable fishing practices while supporting alternative livelihoods in coastal communities.

We need more science-based conservation, not convenient conservation.
Countries should focus on areas where fish spawn and feed amid threats from energy development, tourism, development, habitat destruction and fishing.

Second, we need carefully written rules setting sustainable catch limits and requiring commercial fishing gear that avoids catching unwanted fish and other marine creatures.
Setting aside protected areas that amount to nothing but a rounding error in the range size of tunas won’t protect them from overfishing.

This “just add water” approach to marine protection is a flawed recipe for conservation that is failing to protect the areas of our oceans that require our immediate attention.

Autonaut : automated sea vehicles for monitoring the oceans

Autonaut...the wave propelled unmanned surface vessel (USV)

From Phys

A new company from ESA's UK business incubator has developed an autonomous boat that is propelled by the waves and carries ocean sensors powered by solar energy.

Advances in ocean monitoring are improving our understanding of the seas and environment, including marine life, sea temperatures, pollution and weather.
However, fuel, maintenance and manpower for research ships are costly, and sea conditions restrict where measurements can be made.

The AutoNaut start-up from ESA's Business Incubation Centre in Harwell has come up with a revolutionary automated surface vessel to collect data for long periods at a fraction of the cost.

The vessel is propelled by a unique wave foil that harvests energy from the natural pitching and rolling at sea.
Speeds of 2–5.5 km/h are maintained under most sea conditions.

It is one of the world's first small commercial applications of wave propulsion and it can operate at sea for many weeks at a time, covering hundreds of kilometres in a week in areas and conditions too hazardous for humans.

It is so quiet that it can measure the whistles and clicks of dolphins over large areas.
Using satellite networks, the AutoNaut receives its instructions from anywhere in the world.
It can carry cutting-edge, solar-powered sensors to capture raw measurements, process the data onboard and then send them back to the operators via satellite.
"If a satellite radar picks up suspected oil spills, our AutoNaut can verify it on the spot, map the extent and take water measurements for relay back to shore," said Phil Johnson from the company.

There are four AutoNaut sizes, ranging from 2 to 7 metres.
 With increased length comes greater speed and payload capacity, as well as an increase in the power generation capability for the on board sensors.
Auxiliary electric propulsion or hybrid drive is available for calm conditions and manoeuvring.
A fuel cell may be fitted to provide additional power for sensors, although for most missions the Photo Voltaic panels harvesting solar energy on the deck will be sufficient.

The team recently completed its two-year incubation at the ESA centre.
There, they used highly specialised satellite navigation and communication systems to refine their navigation and control capabilities, and deliver near-realtime data collected from the sensors.

Copernicus Sentinel-3 offers safer navigation at sea


From ESA

Wave information is crucial for people working at sea, to be able to navigate and operate safely.
A new product based on satellite altimeter data detailing ‘Significant Wave Height' now enables this.

High waves are not only dangerous but can threaten delicate procedures at sea, so wave information is paramount for operating safely and efficiently.
For instance, in oil and gas offshore platform operations, historic data and forecasts of wave heights are vital for the safety of personnel, equipment and the environment.

Marine renewable energy operations and site studies require similar information on waves and ship routing can also be improved by such forecasts.

In physical oceanography, the Significant Wave Height (SWH) is defined traditionally as the mean wave height (trough to crest) of the highest third of the waves.
This mathematical definition of ocean wave height is intended to express the height that would be estimated by a trained observer, capturing the most significant waves over the water surface.

Satellite wave measurements come from two main sources: altimetry and Synthetic Aperture Radar (SAR).
The SWH can be obtained through altimetry and directional and spectral information with SAR.

The Copernicus Marine Environment Monitoring Service (CMEMS) released the first real-time global wave product based on satellite data, broadening its offer—previously based on numerical wave forecast models.
Released in the summer of 2017, this new product from satellite altimeter data contains the Significant Wave Height from Jason-3 and from the Copernicus Sentinel-3A satellite altimeter data, provided within three hours after data acquisition.

CMEMS buoy-based in-situ wave coverage
In-situ wave data, typically provided by buoys, are very helpful to validate satellite wave products but in many areas of open water such buoys are not available, because of the difficulty and costliness of installation and maintenance.

It provides quality-filtered and inter-calibrated along-track high-resolution SWH (one measurement every 07 km, or every second).
These measurements contribute to global ocean coverage along the satellite ground tracks with 07 km resolution.

Such satellite wave products represent actual measurements of the waves, covering the entire Earth, regularly and homogeneously over several years.
They often offer a better portrayal of extreme events, which numerical models tend to under estimate.

In-situ wave data, typically provided by buoys, are similarly very helpful but in many open-water areas such moored buoys are not available, mainly due to the technical difficulty and cost of installing and maintaining them in deep ocean, far from the coast (see figure).

Wave data assimilation
Sentinel-3A wave data assimilation in the CMEMS global wave forecast model has a strong impact in the north-west of the Pacific Ocean related to the typhoon season and in the Gulf of Mexico after Hurricane Harvey.

Sentinel-3A's wave data are also assimilated into numerical real-time wave models to provide wave forecasts with better accuracy.
For example, assimilation into the CMEMS global wave forecast model has a strong impact in the north-west of the Pacific Ocean related to the typhoon season and in the Gulf of Mexico after Hurricane Harvey (see figure).

Dr Romain Husson, responsible for wave products at CLS for CMEMS, says, "In the first quarter of 2018, CMEMS will also deliver wave products derived from Sentinel-1A and -1B's SAR instrument.
With respect to altimetry, SAR has the unique ability to measure the wave period and direction on top of the SWH and is particularly well suited for long waves, sometimes also referred to as swell."

MIT unleashes a hypnotic robot fish to help save the oceans

Underwater exploration using an undulating remote-controlled soft robotic fish capable of swimming in three dimensions enables studies of aquatic life in natural habitats.

From Wired by Matt Simon

Like a miniaturized Moby Dick, the pure-white fish wiggles slowly over the reef, ducking under corals and ascending, then descending again, up and down and all around.
Its insides, though, are not flesh, but electronics.
And its flexible tail flicking back and forth is not made of muscle and scales, but elastomer.

SoFi was developed with the goal of being as nondisruptive to ocean life as possible, swimming alongside real fish for several minutes at a time.

The Soft Robotic Fish, aka SoFi, is a hypnotic machine, the likes of which the sea has never seen before.
In a paper published today in Science Robotics, MIT researchers detail the evolution of the world’s strangest fish, and describe how it could be a potentially powerful tool for scientists to study ocean life.

SoFi's lightweight setup includes a single camera, a motor, and the same lithium polymer battery that can be found in consumer smartphones.

Scientists designed SoFi to solve several problems that bedevil oceanic robotics.Problem one: communication.
Underwater vehicles are typically tethered to a boat because radio waves don’t do well in water.
What SoFi’s inventors have opted for instead is sound.

“Radio frequency communication underwater just works for a few centimeters,” says MIT CSAIL roboticist Robert Katzschmann, lead author of the paper.
“Acoustic signals in water can travel for much longer and with much less energy consumption.” Using sound, divers can pilot the robot fish from almost 70 feet away.

 Using its undulating tail and a unique ability to control its own buoyancy, SoFi can swim in a straight line, turn, or dive up or down.

Problem two: classical robot electric motors, known as actuators, can be clunky, and the movement they produce can be stuttery.
But SoFi belongs to a burgeoning class of “soft robots,” which are, well, generally soft, and use air or oil to locomote.
But SoFi’s tail contains two hollow chambers that a pump injects with water.
“All you do is cycle the water back and forth,” says Katzschmann, “and that causes the undulation and the wiggling of the soft tail.” That beautifully natural movement makes for a robot that can swim with the fishes without spooking them.
Contrast that with robots that use jet propulsion, which gives a reef collective panic attacks.

 The team used a water-proof Super Nintendo controller to change SoFi’s speed and have it make specific moves and turns.

Problem three: swimming is energetically expensive.
In particular, fish need to hang tight at certain depths, but constantly correcting by swimming up or down is inefficient.
So fish have evolved a gas-filled organ called a swim bladder, which allows them to achieve neutral buoyancy.
(Sharks, by the way, have massive livers that give them some buoyancy.)

SoFi uses its own swim bladder of sorts, a cylinder that compresses and decompresses air with a piston.
On top of that, the machine doesn’t have all the empty, airy chambers a typical robot might.
"The compartments that usually would be air-tight, air-filled electronics compartments, we filled with oil," says Katzschmann.
That helps give the robot structural integrity and allows it to reach depths of 60 feet by better controlling its internal pressure.

What the researchers have landed on is a truly fishy robot, both in form and function.
And that could be a big deal for fish biologists of the near future.
In their initial studies, the researchers found that fish would sometimes swim alongside their robot, all curious-like.
“Other times they were not at all distracted by anything, while us as divers, if we would get close to those fish they would just swim away instantaneously," says Katzschmann.

For the time being, SoFi is remote-controlled.
But the idea is that future versions would use machine vision to lock onto individual fish and follow them around, all without raising suspicion.
That could help scientists study schooling dynamics, or monitor the health of fish populations in increasingly unhealthy oceans.
“It could help us with the problems of fish avoidance and fish attraction that are associated with other forms of monitoring with robots and divers,” says Northeastern’s Hanumant Singh, who develops autonomous underwater vehicles but was not involved in the research.

Bonus: Unlike Moby Dick, SoFi will never turn on its enemies or make us read 600-page novels about itself.

Canada CHS layer update in the GeoGarage platform

44 nautical charts have been updated & 3 charts withdrawn & 2 new charts added

Russian submarines are prowling around vital undersea cables. It’s making NATO nervous.


From Washington Post by Michael Birnbaum

Russian submarines have dramatically stepped up activity around undersea data cables in the North Atlantic, part of a more aggressive naval posture that has driven NATO to revive a Cold War-era command, according to senior military officials.

The apparent Russian focus on the cables, which provide Internet and other communications connections to North America and Europe, could give the Kremlin the power to sever or tap into vital data lines, the officials said.
Russian submarine activity has increased to levels unseen since the Cold War, they said, sparking hunts in recent months for the elusive watercraft.

“We are now seeing Russian underwater activity in the vicinity of undersea cables that I don’t believe we have ever seen,” said U.S.
Navy Rear Adm. Andrew Lennon, the commander of NATO’s submarine forces.
“Russia is clearly taking an interest in NATO and NATO nations’ undersea infrastructure.”

NATO has responded with plans to reestablish a command post, shuttered after the Cold War, to help secure the North Atlantic.
NATO allies are also rushing to boost anti-submarine warfare capabilities and to develop advanced submarine-detecting planes.

Britain’s top military commander also warned that Russia could imperil the cables that form the backbone of the modern global economy.
The privately owned lines, laid along the some of the same corridors as the first transatlantic telegraph wire in 1858, carry nearly all of the communications on the Internet, facilitating trillions of dollars of daily trade.
If severed, they could snarl the Web.
If tapped, they could give Russia a valuable picture of the tide of the world’s Internet traffic.

“It’s a pattern of activity, and it’s a vulnerability,” said British Air Chief Marshal Stuart Peach, in an interview.
“Can you imagine a scenario where those cables are cut or disrupted, which would immediately and potentially catastrophically affect both our economy and other ways of living if they were disrupted?” Peach said in a speech in London this month.

The Russian Defense Ministry did not respond to a request for comment about the cables.

The Russian sea activity comes as the Kremlin has also pressed against NATO in the air and on land.
Russian jets routinely clip NATO airspace in the Baltics, and troops drilled near NATO territory in September.

Russia has moved to modernize its once-decrepit Soviet-era fleet of submarines, bringing online or overhauling 13 craft since 2014.
That pace, coming after Russia’s annexation of Ukraine’s Crimean peninsula set off a new era of confrontation with the West, has spurred NATO efforts to counter them.
Russia has about 60 full-size submarines, while the United States has 66.

Among Russia’s capabilities, Lennon said, are deep-sea research vessels, including an old converted ballistic submarine that carries smaller submarines.
“They can do oceanographic research, underwater intelligence gathering,” he said.
“And what we have observed is an increased activity of that in the vicinity of undersea cables.
We know that these auxiliary submarines are designed to work on the ocean floor, and they’re transported by the mother ship, and we believe they may be equipped to manipulate objects on the ocean floor.”

That capability could give Russia the ability to sever the cables or tap into them.
The insulated fiber-optic cables are fragile, and ships have damaged them accidentally by dragging their anchors along the seabed.
That damage happens near the shore, where it is relatively easy to fix, not in the deeper Atlantic, where the cost of mischief could be far greater.

Lennon declined to say whether NATO believes Russia has actually touched the cables.
Russian military leaders have acknowledged that the Kremlin is active undersea at levels not seen since the end of the Cold War, when Russia was forced to curtail its submarine program in the face of economic turmoil and disorganization.

“Last year we reached the same level as before the post-Soviet period, in terms of running hours,” said Adm. Vladimir Korolev, the commander of the Russian Navy, earlier this year.
“This is more than 3,000 days at sea for the Russian submarine fleet.
This is an excellent sign.”

The activity has forced a revival of Western sub-hunting skills that lay largely dormant since the end of the Cold War.
Lennon said NATO allies have long practiced submarine-hunting.
But until the last few years, there were few practical needs for close tracking, military officials said.

In recent months, the U.S. Navy has flown sorties in the areas where Russia is known to operate its submarines, according to aircraft trackers that use publicly available transponder data.
On Thursday, for example, one of the planes shot off from Naval Air Station Sigonella in Sicily, headed eastward into the Mediterranean.
It flew the same mission a day earlier.

The trackers have captured at least 10 missions carried out by U.S. submarine-tracking planes this month, excluding trips when the planes simply appeared to be in transit from one base to another.
November was even busier, with at least 17 missions captured by the trackers.

NATO does not comment on specific submarine-tracking flights and declined to release data, citing the classified nature of the missions.
But NATO officials say that their submarine-tracking activities have significantly increased in the region.

It’s a little-known twist in the cyber-warfare between nations that carries potentially devastating consequences.
At a time when more than 95% of everything that moves on the global Internet passes through just 200 undersea fiber-optic cables, potential adversaries such as the US, Russia, China, and Iran are focusing on these deep-sea information pipes as rich sources of intelligence as well as targets in war.
The weapons earmarked for the struggle include submarines, underwater drones, robots and specialized ships and divers.
The new battlefield is also a gray legal zone: Current Law of the Sea conventions cover some aspects of undersea cables but not hostile acts.
There’s evidence that missions are already underway and that most big powers, including the US, are keen on engaging in such activities.
Cables can also be attacked by terrorists and other non-state actors.
The damage from such hard-to-detect acts could be enormous, since a foe’s economy, in addition to military and diplomatic communications, could be blinded.
As more nations exploit the Internet for political or military gain, it’s also clear that the tactical concept of undersea cables as critical assets to be attacked or defended is an idea whose time has come

Submarines are particularly potent war-fighting craft because they can generally only be heard, not seen, underwater.
They can serve as a retaliatory strike force in case of nuclear war, threaten military resupply efforts and expand the range of conventional firepower available for use in lower-level conflicts.

The vessels are a good fit for the Kremlin’s strategy of making do with less than its rivals, analysts say: Russia’s foes need vast resources to track a single undersea craft, making the submarines’ cost-to-mischief ratio attractive.
Even as Russia remains a vastly weaker military force than NATO, the Kremlin has been able to pack an outsize punch in its confrontation with the West through the seizure of Crimea, support for the Syrian regime and, according to U.S. intelligence, its attempts to influence the U.S. election.

“You go off and you try to add expense for anything that we’re doing, or you put things at risk that are of value to us, and submarines give them the capability to do it,” a senior NATO official said of the Russian approach, speaking on the condition of anonymity to discuss sensitive intelligence assessments.

Russian military planners can say, “I can build fewer of them, I can have better quality, and I can put at risk and challenge and make it difficult for NATO,” the official said.

Still, some analysts say the threat to cables may be overblown.

“Arguably, the Russians wouldn’t be doing their jobs if they couldn’t threaten underwater cables.
Certainly, NATO allies would not be doing theirs if they were unable to counter that,” said Adam Thomson, a former British ambassador to NATO.

Russian military planners have publicized their repeated use of submarine-launched Kalibr cruise missiles during their incursion into Syria, which began in fall 2015.
(In Syria, the missiles have not always hit their targets, according to U.S. intelligence officials, undermining somewhat the Russian claims of potency.)

NATO’s hunts — which have stretched across the Baltic, Mediterranean and Atlantic — have mobilized submarine-tracking frigates, sonar-equipped P8 Poseidon planes and helicopters, and attack submarines that have combed the seas.

“The Russians are operating all over the Atlantic,” said NATO Secretary General Jens Stoltenberg.
“They are also operating closer to our shores.”

Russia’s enhanced submarine powers give urgency to NATO’s new efforts to ensure that it can get forces to the battlefront if there is a conflict, Stoltenberg said.
In addition to the new Atlantic-focused command, the alliance also plans to create another command dedicated to enabling military forces to travel quickly across Europe.

NATO defense ministers approved the creation of the commands at a November meeting.
Further details are expected in February.
The plans are still being negotiated, but they currently include the North Atlantic command being embedded inside the U.S. Fleet Forces Command in Norfolk, which would transform into a broader NATO joint force command if there was a conflict, a NATO diplomat said, speaking on the condition of anonymity to discuss plans that have not been finalized.

“Credible deterrence is linked to credible reinforcement capabilities,” Stoltenberg said.
“We’re a transatlantic alliance. You need to be able to cross the Atlantic.”

IBM AI predictions include AI powered ocean microbots and unbiased AI

Real-time oceanic data is elusive
By 2025, more than half of the world’s population will be living in water-stressed areas.
But scientists struggle to collect and analyze even the most fundamental data about the real-time conditions of our oceans, lakes and rivers.
There are specialized sensors that can be deployed to detect specific chemicals and conditions in water, but they miss unanticipated ones, like invasive species or the introduction of new chemicals from run off.
Plankton, however, are natural, biological sensors of aquatic health.
Even slight changes in water quality affect their behavior.
They also form the foundation of the oceanic food chain, which serves as the primary source of protein for more than a billion people.
Yet very little is known about how plankton behave in their natural habitat, because studying them typically requires collecting samples and shipping them to a laboratory.
Small autonomous AI microscopes, networked in the cloud and deployed around the world, will continually monitor in real time the health of one of Earth's most important and threatened resources: water.
Learn more about these microscopes and other IBM 5 in 5 predictions

From NextBigFutures by Brian Wang

IBM’s mission is to help their clients change the way the world works.
There’s no better example of that than IBM Research’s annual “5 in 5” technology predictions.
Each year, we showcase some of the biggest breakthroughs coming out of IBM Research’s global labs – five technologies that they believe will fundamentally reshape business and society in the next five years.
This innovation is informed by research taking place at IBM Labs, leading edge work taking place with our clients, and trends we see in the tech/business landscape.

Later today, they’ll introduce the scientists behind this year’s 5 in 5 at a Science Slam held at the site of IBM’s biggest client event of the year: Think 2018 in Las Vegas.
Watch it live or catch the replay here.
Science Slams give their researchers the opportunity to convey the importance of their work to a general audience in a very short span of time — approximately 5 minutes.
they have found this to be an extremely useful exercise that makes our innovation more accessible by distilling it down to its core essentials.

Here’s a summary of the two of the five predictions IBM scientists will present this year.

Illustration of the AI-powered robot microscope
The microscope has no lens and relies on an imager chip, like the one in any cell phone, to capture the shadow of the plankton as it swims over the chip, generating a digital sample of its health, without the need for focusing. 

Our oceans are dirty.
AI-powered robot microscopes may save them.
In five years, small, autonomous AI microscopes, networked in the cloud and deployed around the world, will continually monitor in real time the health of one of Earth’s most important and threatened resources: water.
IBM scientists are working on an approach that uses plankton, which are natural, biological sensors of aquatic health.
AI microscopes can be placed in bodies of water to track plankton movement in 3D, in their natural environment, and use this information to predict their behavior and health.
This could help in situations like oil spills and runoff from land-based pollution sources, and to predict threats such as red tides.

AI bias will explode.
But only the unbiased AI will survive.
Within five years, we will have new solutions to counter a substantial increase in the number of biased AI systems and algorithms.
As we work to develop AI systems we can trust, it’s critical to develop and train these systems with data that is fair, interpretable and free of racial, gender, or ideological biases.
With this goal in mind, IBM researchers developed a method to reduce the bias that may be present in a training dataset, such that any AI algorithm that later learns from that dataset will perpetuate as little inequity as possible.
IBM scientists also devised a way to test AI systems even when the training data is not available.

"Hold your breath," says inventor Tom Zimmerman. 
"This is the world without plankton."
These tiny organisms produce two-thirds of our planet's oxygen -- without them, life as we know it wouldn't exist.
In this talk and tech demo, Zimmerman and cell engineer Simone Bianco hook up a 3D microscope to a drop of water and take you scuba diving with plankton.
Learn more about these mesmerizing creatures and get inspired to protect them against ongoing threats from climate change.

Our oceans are dirty.
AI-powered robot microscopes may save them.

In five years, small autonomous AI microscopes, networked in the cloud and deployed around the world, will continually monitor the condition of the natural resource most critical to our survival: water.

By 2025, more than half of the world’s population will be living in water-stressed areas.
But scientists struggle to collect and analyze even the most fundamental data about the real-time conditions of our oceans, lakes and rivers.
There are specialized sensors that can be deployed to detect specific chemicals and conditions in water, but they miss unanticipated ones, like invasive species or the introduction of new chemicals from run off. Plankton, however, are natural, biological sensors of aquatic health.

Yet very little is known about how plankton behave in their natural habitat, because studying them typically requires collecting samples and shipping them to a laboratory.

IBM researchers are building small, autonomous microscopes that can be placed in bodies of water to monitor plankton in situ, identifying different species and tracking their movement in three dimensions.
The findings can be used to better understand their behavior, such as how they respond to changes to their environment caused by everything from temperature to oil spills to run off.
They could even be used to predict threats to our water supply, like red tides.

The microscope has no lens and relies on an imager chip, like the one in any cell phone, to capture the shadow of the plankton as it swims over the chip, generating a digital sample of its health, without the need for focusing. In the future, the microscope could be outfitted with high performance, low power AI technology to analyze and interpret the data locally, reporting any abnormalities in real-time so they can be acted upon immediately.

Because what’s good for plankton is good for all of us.

AI bias will explode.
But only the unbiased AI will survive.

Within five years, the number of biased AI systems and algorithms will increase, much like the increase of computer viruses in the early aughts.
But we will deal with them accordingly –coming up with new solutions to control bias in AI and champion AI systems free of it.

AI systems are only as good as the data we put into them.
Bad data can contain implicit racial, gender, or ideological biases.
Many AI systems will continue to be trained using bad data, making this an ongoing problem.
But IBM believes that bias can be tamed and that the AI systems
that will tackle bias will be the most successful.

The number of biased AI systems and algorithms will dramatically increase, but we will come up with new solutions to control bias and champion AI systems free of it.
We may even improve ourselves in the process.

As humans and AI increasingly work together to make decisions., researchers are looking at ways to ensure human bias does not affect the data or algorithms used to inform those decisions

The MIT-IBM Watson AI Lab’s efforts on shared prosperity are drawing on recent advances in AI and computational cognitive modeling, such as contractual approaches to ethics, to describe principles that people use in decision-making and determine how human minds apply them.
The goal is to build machines that apply certain human values and principles in decision-making.

A crucial principle, for both humans and machines, is to avoid bias and therefore prevent discrimination.
Bias in AI system mainly occurs in the data or in the algorithmic model.
As we work to develop AI systems we can trust, it’s critical to develop and train these systems with data that is unbiased and to develop algorithms that can be easily explained.
To this aim, IBM researchers developed a methodology to reduce the bias that may be present in a training dataset, such that any AI algorithm that later learns from that dataset will perpetuate as little inequity as possible.

IBM scientists also devised a methodology to test AI systems even when the training data is not available.
This research proposes that an independent bias rating system can determine the fairness of an AI system.
For example, the AI service could be unbiased and able to compensate for data bias (the ideal scenario), or it could be just following the bias properties of its training (which could be solved by data de-biasing techniques), or it could even introduce bias whether the data is fair or not (the worst scenario).
The AI end-user will be able to determine the trustworthiness of each system, based on its level of bias.

Identifying and mitigating bias in AI systems is essential to building trust between humans and machines that learn.
As AI systems find, understand, and point out human inconsistencies in decision making, they could also reveal ways in which we are partial, parochial, and cognitively biased, leading us to adopt more impartial or egalitarian views.

In the process of recognizing our bias and teaching machines about our common values, we may improve more than AI.
We might just improve ourselves.
