These are the cleverest, weirdest mapping ideas ever patented

Inventors have dreamt up some strange ways to map and navigate the world—and have patented nearly 100 different ways to fold a map.

In 1912 an inventor in New York City named Joseph W. Jones filed a patent for a “Combined Road-Map and Odometer” that is arguably the forerunner to today’s dashboard GPS navigation systems.

Jones’ invention was for a complex apparatus (see first slide in gallery above) that would display route directions and landmarks as a car travels between two specific points.
The disc in the patent drawing above describes the route from Columbus Circle in Manhattan to Waterbury, Connecticut.

This is just one of the more than 300 map-related inventions uncovered by Mark Monmonier, a geographer at Syracuse University’s Maxwell School.
Monmonier’s new book Patents and Cartographic Inventions is a fascinating look at more than a century and a half of clever—and not-so-clever—ideas, and the inventors behind them.
The patents cover everything from internally illuminated globes to streetcar transfer tickets to complicated map-folding schemes.

Patents have generally been ignored by map historians, Monmonier says, but they reveal a lot about how people have used maps over the years.
He found that like many discoveries and inventions, patents for similar ideas seemed to spring up independently around the same time—a phenomenon known as the theory of multiple discoveries.

Navigating the road

Such was the case for several patents for inventions, including Jones’ apparatus, intended to help drivers find their way around at the beginning of the 20th century.
At the time, automobiles were just starting to become popular, but good roads, decent signposting, and accurate road maps were still scarce.
Inventors responded with a variety of solutions.
“Some of them I think were extremely clever,” Monmonier says.

The Chadwick Automatic Road Guide, patented in 1916 by Lee Sherman Chadwick of Pottstown, Pennsylvania used a rotating disc connected to the speedometer to help drivers find their way along a predetermined route, similar to Jones’ system.
But Chadwick’s invention, possibly inspired by the player pianos that were popular at the time, added a warning sound to alert drivers of impending turns or hazards and displayed symbols to indicate what was ahead.

Anticipating GPS voice navigation by almost a century, George Boyden of Manhattan patented a “Vehicle Signaling System” in 1916 that included a phonograph and a megaphone (indicated by number 22 in the drawing above) to announce directions for the driver to follow.
Boyden apparently never developed the idea, though Jones and Chadwick briefly manufactured and marketed their competing devices.

Many of the patents Monmonier discovered were impractical and some were downright ridiculous. Several inventors inspired by Sputnik’s successful launch into orbit in 1957 designed mechanical globes with satellites circling them.
The wildest of these ideas was a 1963 patent that, Monmonier writes, “might have made made cartoonist [Rube] Goldbergscratch his head.”
The patent, by Brothers Thomas and Frank Novak of Brownsville, Pennsylvanis, described a stationary globe with a rotating air duct that would use an “upward air blast” to hold a sphere aloft as it orbited the Earth (above).
You don’t need to be an engineer to know this would have never worked.

The perennial challenge of folding a map

Ninety-two of the 304 filings Monmonier mined from U.S. Patent Office records were for map-folding schemes.
The frustration of refolding maps, he notes, is perhaps best described by James M. Barrie, the author of “Peter Pan.”
Barrie wrote in 1889: “Prominent among the curses of civilisation is the map that folds up ‘convenient for the pocket.’ There are men who can do almost anything except shut a map. It is calculated that the energy wasted yearly in denouncing these maps to their face would build the Eiffel Tower in thirteen weeks.”
Map-folding is a category that has received scant attention from historians, Monmonier says.
It may seem mundane, “but when it comes down to making map information accessible, how one folds is very important,” he says.

From the late 19th century into the early 21st century, a number of inventors tackled the problem of map folding with increasingly complex schemes.
One of the most interesting ideas is a “Book Fold Map” patented by Stacy Boyer of Casper, Wyoming in 1925.
It took nine drawings to explain the scheme, which involved numerous folds and cuts to fashion an accordion fold partitioning a map into 48 panels.
Those panels would then be attached to a cover, like a book (fig. 9 above).

Users would move around the map by leafing through the panels like book pages from left to right, or by flipping them up and down.
Monmonier found correspondence between Boyer and his patent examiner in which the examiner claimed he had unsuccessfully tried to make a working version of Boyer’s book based on his drawings, concluding that the “map fails to function.”
He asked the inventor to submit a working model.

Intrigued, Monmonier attempted to make one himself.
It was a struggle, even for a noted map expert, but eventually he was able to reverse engineer a working model by carefully studying figures 1 and 9, making the prescribed cuts and folds, and taping the map to a card (If you want to give it a go, it’s US Patent 1,531,065).
In all, it took Boyer 27 months of revisions and rejections to finally get his patent approved.

A dairy farmer turned inventor

By scouring documents including census records, newspapers, government employment records, military service records, and city directories, Monmonier was able to gain insight into the lives of the people behind the patents.

His book highlights the story of John Byron Plato of Colorado, a high school-educated dairy farmer with several patents to his name, including a device to stop a horse from running away with a wagon attached to it.
His map-related patent was for a clever “clock system” for assigning addresses to rural residences in areas that lacked a regular street numbering system (above).

It was a failed attempt to sell cattle that inspired Plato to devise the clock system.
He had lined up some out-of-town buyers to come to rural Bloomfield, Colorado, to inspect his cattle, but since Plato’s only address was a P.O Box, they went to the post office to ask for directions to his farm.
The clerk didn’t know Plato and said they would need to wait for the mail carrier, who would not return until the next day.
Annoyed, the buyers left, and as Plato told the magazine Illustrated World in 1917, “that killed a mighty profitable bargain.”

Unlike most of the inventors in the book, Plato managed to successfully market his clock system, selling licenses to several counties in New York.
His business appears to have foundered during the Great Depression, but Plato bounced back.
He became a map expert for the government in Washington D.C., married a woman 24 years his junior, donated 50 acres of woodland property for a Girl Scout camp, and lived to be 89.

Monmonier’s fascination with the details of some of these inventors’ lives was partly inspired by the discovery of an interesting biographical detail of his own: His maternal grandfather was an inventor, with several patents for things like milk bottle caps.
Monmonier hopes the inventors and inventions in his book will inspire others with an interest in map history to take a closer look at this neglected side of maps.

Walking in Shackleton's footsteps

A detailed map of the Shackleton crossing features in our updated South Georgia map

From BBC by Jonathan Amos

Shackleton's escape from the Antarctic in 1916 is well told.
It is without doubt a remarkable story given the many challenges he and his crew had to overcome after losing their ship, the Endurance.
For months they drifted on sea-ice, before making a lifeboat dash to Elephant Island, followed by a hazardous sail across the Southern Ocean to South Georgia.
And if that wasn't enough, Shackleton and two colleagues then trekked over the mountains and ice fields of the British Overseas Territory to a whaling station to get help for the men stranded further back along the escape route.
Precisely how the explorer accomplished the last leg of the journey, across South Georgia, you can now follow in detail on a new map of the island.

The British Antarctic Survey (BAS) has updated its 1:200,000 rendering of the territory, with a special feature it calls The Shackleton Crossing on the map's B-side.
"We've never had a product like this before, and we've put a lot of effort into making it as detailed as possible," explained Laura Gerrish, a BAS mapping specialist.
"We've used stereo pairs of very high-resolution imagery to make the elevation data; and we've manually digitised all the rock and ice areas.
"We don't intend it as the route you must take, but it does show those who want to recreate the crossing the paths that are available," she told BBC News.

 A 2016 satellite image: The big glaciers are pulling back up their fjords
 
The Shackleton portion of the map is reproduced at 1:40,000 scale, with three insets at 1:25,000.
These illustrate the more dangerous parts of the 30km trek*, including The Razorback ridge and Breakwind Gap, which have near-vertical descents.
* The direct distance between Shackleton's landing point in King Haakon Bay and Stromness whaling station is just over 30km, but the men had to climb and descend 600m-high peaks, and at one point took a significant wrong turn. 
Shackleton, with Tom Crean and Frank Worsley, negotiated these obstacles by tobogganing on their coiled ropes.

 The South Georgia map was last updated in 2004
The new South Georgia map has been updated & includes new features such as bays and lakes.
see BAS
 
If the trio could retrace their steps today, they would be astonished at the changes that have taken place.
South Georgia is warming and its ice fields are in rapid retreat - something that has become very evident since 2004, the last time BAS updated the map.
"The data we have now is much more accurate of course, but there are many more new bays, coves, promontories and lakes, simply because the glaciers have retreated so much," Ms Gerrish said.
I wrote in March about the glacial history of South Georgia.
Some 20,000 years ago, during the last ice age, the island's glaciers pushed out 50km and more from their current positions, reaching to the edge of the continental shelf.


Now, the glaciers that formed that ice sheet are constrained to fjords, with some of the marine-terminating streams even pulling back on to land.
"I've been working at South Georgia for 15 years, and every time I go down I say to myself 'I can't believe the glaciers have moved again'," said Dr Mark Belchier, who is the South Georgia science manager at BAS.

Sir Ernest Shackleton and his crew took bitter defeat and turned it into heroic survival.
Early this century, members of the imperial Trans-Antarctic Expedition watched as their ship, the Endurance was crushed by the frozen sea.
They were left with no radio and no hope of rescue.
For more than a year, they drifted on packed ice, surviving on seal, penguin, and eventually dog meat, while battling freezing temperatures and mind-numbing boredom.
When Shackleton, along with all 28 members of the expedition, emerged at Stromness whaling station in May, 1916, almost two years after their departure, the world was shocked.

The fastest retreating ice streams are on the northern or eastern coast - depending on how you want to describe the arcing territory. It's the "sunny side".
Neumayer and Nordenskjold, the two mighty glaciers that feed Cumberland Bay, have retreated 6km. But even on the south side, the changes are running at pace.
The 4km retreat of Twitcher Glacier since the last edition of the map has opened up a new bay. And with the next-door Iris Glacier also reversing, a new promontory has emerged.
Some of these features have yet to be labelled on the map.
By the time the next edition comes out, the UK Antarctic Place-names Committee should have suggestions.
You may well be wondering what climate change means for South Georgia.
You often hear people who've been there describe it as magical haven for wildlife.
It is said that on some beaches during breeding season you literally cannot move for all the penguins and seals.
One benefit then of the ice retreat is that more breeding grounds will open up.


On the other hand, the ice loss has big implications if there is a rodent infestation.
A lot of money and effort has gone into ridding South Georgia of the rats that once attacked the ground nests of seabirds like the wandering albatross.
The glaciers acted as barriers that limited the rodents' range.
If the rats come back - perhaps jumping off some tourist ship - they will find it much easier to get around.
"But just in general, a lot of the species on South Georgia are highly adapted to that relatively stable cold environment, and there's nowhere really for them to go if conditions change," explained Dr Belchier.
"And they could also be vulnerable to other species that invade from further north."
The new map was produced in collaboration with the expedition and advisory panel at the government of South Georgia and South Sandwich Islands (GSGSSI).
It can be purchased from the UK Antarctic Heritage Trust.
Much of the underlying data is also freely available to view and download from the South Georgia GIS portal.

1st flight for Edmond de Rothschild maxi trimaran

With an LOA of 32 metres, Edmond De Rothschild is the largest purpose-built foiling trimaran in the world — and more than double the length of the AC45 racing catamarans that competed at the America's Cup in Bermuda earlier this summer.
Speaking after a successful day on the water, SĂ©bastien Josse of Gitana said, “We immediately saw that the boat was keeping her promises: stiff and safe and begging to unleash her power. The first time the boat took off was an incredible moment. We had 15-17 knots of breeze and flat seas, with waves of less than a metre — everything was in place to fly. Aboard the boat there was a mixture of excitement and surprise, as well as pride,” he added.
“Even though we're only at the start, it's hugely satisfying to see that we're heading in the right direction.”

Spire, 40 cubesats in orbit, competing more directly in space-based ship-tracking market

Spire tracks more than 75,000 ships per day now, and continues to build out its satellite and analytics infrastructure.

From SpaceNews by Caleb Henry

Spire is wading deeper into the ship-tracking business, challenging established competitors operating fleets of much bigger satellites.
The startup has come a long way since the crowdfunded launch of its first cubesat four years ago. Today, Spire’s constellation numbers 40 cubesats — with more on the way. As its fleet grows, so does its ambition.

Vessel tracking : satellite vs terrestrial AIS

The San Francisco-based company debuted two maritime products Aug. 29, a ship-tracking analytics platform called Sense Vessels, and a vessel-location forecaster called Predict, while making thinly veiled jabs at competitors Orbcomm, whose newly launched second-generation constellation has lost six out of 18 satellites, and exactEarth, which lost a satellite in April.
“Our customers have a diverse set of needs but almost all of them can be served by more and better data served with high reliability,” Kyle Brazil, Spire’s Sense product manager, said in an Aug. 29 statement.
“With many competitor’s aging satellite infrastructure increasingly failing, our strategy of launching a constantly upgraded constellation is proving to be a superior approach.”

It’s doubtful Orbcomm and exactEarth see their in-orbit assets as “aging satellite infrastructure.” Orbcomm’s OG2 satellites launched in 2014 and 2015, and exactEarth’s exactView system is mid-deployment — but Spire has established itself as meaningful competitive player.
The U.S. National Geospatial-Intelligence Agency is one of Spire’s customers.

Sixty million ship locations retrieved from Spire Sense satellites visualised
using Geomesa on Amazon Elastic Map Reduce.

Spire satellites carry automatic identification system (AIS) sensors for tracking boats and ships, as well as GPS radio-occultation sensors for commercial weather data.
More recent satellites include Automatic Dependent Surveillance-Broadcast (ADS-B) sensors for an aircraft-tracking service the company plans to launch later this year.

Spire, which began deploying its constellation of weather and maritime data-gathering satellites in earnest in 2015, uses cubesats to compete with Rochelle Park, New Jersey-based Orbcomm, whose 170-kilogram OG2 satellites also carry AIS payloads, and exactEarth, a Canadian company with a first-generation constellation of seven AIS satellites and a second-generation network consisting of AIS hosted payloads launching on Iridium Next’s 860-kilogram satellites.

Because of OG2’s unexpectedly high failure rate, Orbcomm is planning a third-generation supplementary satellite system while relying more heavily on partner Inmarsat of London to fill the gaps.
Orbcomm said Aug. 3 that its three most recent malfunctioning OG2 satellites are worth roughly $10 million each.
Note : Orbcomm did not respond to SpaceNews inquiries by press time.

In April, exactEarth received a nearly $2.7 million insurance payout for EV5, an AIS satellite from Fairfax, Virginia-based SpaceQuest that ceased communicating in February.
The satellite had launched in November 2013 on a Kosmotras Dnepr rocket.

This movie shows one month of AIS plots (20 million plots) as provided by Spire and visually analyzed by a LuciadLightspeed application.
The movie shows the vast amount of data instantly visualized, filtered, and analyzed at over 60 FPS on a desktop machine.
The data consists of a set of terrestrial AIS plots with detailed information in the San Francisco and Los Angeles harbors, conflated with a worldwide coverage of satellite AIS data.
The two data sets and the conflation happens on the fly in the model.
This meaning that the two files are merged into one model of 20 million plots, where the highlight of a single ship, highlights the tracks of both source data files.

Despite that setback, exactEarth has 65 hosted payloads launching on Iridium Next satellites, spokesperson Nicole Schill told SpaceNews Aug. 31.
From the two SpaceX Iridium Next launches completed, exactEarth has 13 hosted payloads in orbit, she said, nine of which are in service and four are drifting to their orbital planes.
The hosted payload constellation, operated by Harris Corp., will comprise exactEarth’s second-generation constellation.
The company has one more first-generation payload awaiting launch on the long-delayed PAZ satellite that investor Hisdesat of Spain recently shifted from Kosmotras to SpaceX. Schill said PAZ is expected to launch in December 2017; Kosmotras was originally to launch the satellite in 2014.
“Today the exactEarth/Harris alliance is operating the world’s highest performance satellite AIS system and this capability will get significantly better over the next year as the remainder of the Iridium NEXT constellation is deployed to complete the real-time exactViewRT system,” Peter Mabson, exactEarth CEO, told SpaceNews in an Aug. 30 email.
Schill said exactEarth’s total constellation will be over 70 AIS payloads by the end of 2018.

Spire spokesperson Nick Allain told SpaceNews Aug. 29 that Spire still intends to field 100 nanosatellites, but can’t give a date for completion due to the unpredictable nature of launch delays.

Launch delays will likely decide whether exactEarth or Spire control a larger AIS constellation.
Spire had projected in 2015 that by this year the company would operate 100 cubesats.
Last month’s Soyuz launch carried eight Spire satellites, one of which was placed in the wrong orbit.
“Our satellites now collect data from over 75 thousand unique ships each day,” said Spire CEO Peter Platzer said in an Aug. 29 statement.
“They’re tracked in a database of over 300 thousand ships that we keep tabs on, and we can predict where ships are going based on their past and present behavior.”

The 65 satellites in exactView RT powered by Harris revolutionizes the ship tracking industry providing the only solution for global real-time vessel monitoring

Spire, exactEarth and Orbcomm have all weathered launch delays that set back their constellation goals by at least a year or more.
Schill said the delays to Iridium Next were long enough to afford the company time to add more hosted payloads — the original number was 58, not 65.

Spire attributed its ability to launch the new maritime products to new satellites, ground stations and on-orbit upgrades, and said progress on these fronts will continue throughout this year and 2018, along with advancements in machine learning.
In addition to the 40 cubesats Spire operates today, Allain said the company has a network of 25 ground stations to downlink data, and is continuing to grow that number as well.

Stranded on Norwegian island, rowers end their Arctic mission

From NYTimes by Megan Specia

An international team of rowers ended a record-breaking expedition through the Arctic Ocean on Monday after becoming stranded on a remote Norwegian island partway through their month-and-a-half-long journey.

They had set out to break several world records while using the mission to raise money for a school in the Himalayas.
They achieved 11 of 12 expected world records, related to distance traveled and location in the Arctic, before having to call off their mission.


courtesy of DailyMail
Beginning in July 2017, a crew of international rowers carries the coveted Explorer's Club flag on a pioneering two-stage Arctic expedition.
The stage of the expedition departs Tromsø (Norway) for Longyearbyen (Svalbard), and tried to be officially recognized as the first ever South to North row in the Arctic, reaching the northernmost latitude achieved by a rowing crew.

The exploratory Polar Row then continued as the crew depart Svalbard to cross 2000km of icy Arctic waters to reach Iceland.
The crew had no sails and no motor to aid them in their quest, and was buffeted by strong and unpredictable Arctic winds (in stark contrast to completely wind dependent lower latitudes' ocean rowing routes). 

Now, it could be at least another week before the crew of six adventurers, whose expedition was called the Polar Row, is evacuated from the island where they sought refuge on Aug. 19, according to social media posts from its members.

The rowers — from Britain, Iceland, India, Norway and the United States — took to sea from the northern coast of Norway on July 20 and headed north to an island on the Svalbard archipelago.
They then continued to the Arctic ice shelf — the first rowing crew recorded as making it that far north — before turning south toward Iceland.

But with the skies cloudy for days at a time, the boat’s solar-powered batteries drained, and its electrical equipment shut off.
That left the rowers without navigational aids and forced them to rely on manual steering, according to a post on the Polar Row Facebook page that recounted the decision to head for shore.

As conditions aboard the 30-foot boat deteriorated, the rowers abandoned their intended course and headed for Jan Mayen island instead.
That small volcanic island is about halfway between Norway and Greenland.

“I’ve never been so wet and cold for so long,” Alex Gregory, a British rower and two-time Olympic gold medalist, wrote in an Instagram post on Aug. 17, two days before the crew reached land.
“It’s seeping into my bones, there is absolutely no escape from it.”

On Monday, nine days after reaching Jan Mayen, the crew officially ended its journey.

“A successful expedition is also one where everyone goes home safe and in good health to their family and friends,” one of the rowers, Carlo Facchino, wrote on the Polar Row Facebook page.
“With that, our expedition now comes to an end having achieved the ultimate in success.”

Jan Mayen is not permanently inhabited, but is staffed by around 18 members of the Norwegian Armed Forces and the Norwegian Meteorological Institute who have a base there and welcomed the crew into their facilities.

As crew members wait to be evacuated, they have been detailing their journey in social media posts.
“The hospitality has been unbelievable — they’ve saved our lives,” Mr. Gregory said in a video posted to his Twitter account.
The clip shows a desolate beach strewn with driftwood and whale bones.
Private airplanes are not permitted to land on the island, so the rowers are waiting to see when they might be able to return home.
“There is news that a boat may be coming past next week that may have space on board for us,” Mr. Gregory wrote in a post on Saturday.
“Hopefully they will be willing to allow us to jump aboard and begin the journey home.”

The expedition’s captain, Fiann Paul, initially tried to have a fresh crew brought to the island to continue the journey, he said in an email.
Flight restrictions on Jan Mayen made that impossible, but Mr. Paul vowed to attempt the Arctic journey again.
“We will row again,” he said, “maybe an even bigger route than this one.”

From East to West: scientists solve birds' ability to navigate longitude

Migrating birds navigate thousands of miles each year
Photo : Jens Meyer

From The Conversation by Richard Holland

Birds have an impressive ability to navigate.
They can fly long distances, to places that they may never have visited before, sometimes returning home after months away.

Though there has been a lot of research in this area, scientists are still trying to understand exactly how they manage to find their intended destinations.

 Researchers track migrations of individual birds around the globe using satellite and GPS technology.
This video, along with the video "Bird migrations in Movebank: Americas" shows the recorded movements of 1,654 individual birds that were tracked between 1992 and 2012.

Much of the research has focused on homing pigeons, which are famous for their ability to return to their lofts after long distance displacements.
Evidence suggests that pigeons use a combination of olfactory cues to locate their position, and then the sun as a compass to head in the right direction.

We call this “map and compass navigation”, as it mirrors human orienteering strategies: we locate our position on a map, then use a compass to head in the right direction.

But pigeons navigate over relatively short distances, in the region of tens to hundreds of kilometres. Migratory birds, on the other hand, face a much bigger challenge.
Every year, billions of small songbirds travel thousands of kilometres between their breeding areas in Europe and winter refuges in Africa.

This journey is one of the most dangerous things the birds will do, and if they cannot pinpoint the right habitat, they will not survive. We know from displacement experiments that these birds can also correct their path from places they have never been to, sometimes from across continents, such as in a study on white crowned sparrows in the US.

Over these vast distances, the cues that pigeons use may not work for migrating birds, and so scientists think they may require a more global mapping mechanism.
Navigation and location

To locate our position, we humans calculate latitude and longitude, that is our position on the north-south and east-west axes of the earth.
Human navigators have been able to calculate latitude from the height of the sun at midday for millennia, but it took us much longer to work out how to calculate longitude.

Eventually it was solved by having a highly accurate clock that could be used to tell the difference between local sunrise time and Greenwich meantime.
Initially, scientists thought birds might use a similar mechanism, but so far no evidence suggests that shifting a migratory bird’s body clock effects its navigation ability.

There is another possibility, however, which has been proposed for some time, but never tested – until now.
The earth’s magnetic pole and the geographical north pole (true north) are not in the same place.
This means that when using a magnetic compass, there is some angular difference between magnetic and true north, which varies depending on where you are on the earth.
In Europe, this difference, known as declination, is consistent on an east west axis, and so can possibly be a clue to longitude.


This episode explores animals' ability to perceive magnetism or “magnetoreception."

We know from behavioral evidence that many organisms, from bacteria, to lobsters, to pigeons sense and respond to magnetic fields but we are just starting to learn how this works.

To find out whether declination is used by migrating birds, we tested the orientation of migratory reed warblers.
Migrating birds that are kept in a cage will show increased activity, and they tend to hop in the direction they migrate.
We used this technique to measure their orientation after we had changed the declination of the magnetic field by eight degrees.

First, the birds were tested at the Courish spit in Russia, but the changed declination – in combination with unchanged magnetic intensity – indicated a location near Aberdeen in Scotland.
All other cues were available and still told them they were in Russia.

If the birds were simply responding to the change in declination – like a magnetic compass would – they would have only shifted eight degrees.
But we saw a dramatic reorientation: instead of facing their normal south-west, they turned to face south-east.

This was not consistent with a magnetic compass response, but was consistent with the birds thinking they had been displaced to Scotland, and correcting to return to their normal path.
That is to say they were hopping towards the start of their migratory path as if they were near Aberdeen, not in Russia.

This means that it seems that declination is a cue to longitudinal position in these birds.

There are still some questions that need answering, however.
We still don’t know for certain how birds detect the magnetic field, for example.
And while declination varies consistently in Europe and the US, if you go east, it does not give such a clear picture of where the bird is, with many values potentially indicating more than one location.

There is definitely still more to learn about how birds navigate, but our findings could open up a whole new world of research.

Nations will start talks to protect fish of the high seas

Critically important fisheries face widespread population declines while fishing pressures continue to increase.
Together we must take action towards managing fishing sustainably.

From NYTimes by Somini Sengupta

More than half of the world’s oceans belong to no one, which often makes their riches ripe for plunder.

Now, countries around the world have taken the first step to protect the precious resources of the high seas.
In late July, after two years of talks, diplomats at the United Nations recommended starting treaty negotiations to create marine protected areas in waters beyond national jurisdiction — and in turn, begin the high-stakes diplomatic jostling over how much to protect and how to enforce rules.
“The high seas are the biggest reserve of biodiversity on the planet,” Peter Thomson, the ambassador of Fiji and current president of the United Nations General Assembly, said in an interview after the negotiations.
“We can’t continue in an ungoverned way if we are concerned about protecting biodiversity and protecting marine life.”
Without a new international system to regulate all human activity on the high seas, those international waters remain “a pirate zone,” Mr. Thomson said.

Lofty ambitions, though, are likely to collide with hard-knuckled diplomatic bargaining.
Some countries resist the creation of a new governing body to regulate the high seas, arguing that existing regional organizations and rules are sufficient.
The commercial interests are powerful.
Russian and Norwegian vessels go to the high seas for krill fishing; Japanese and Chinese vessels go there for tuna. India and China are exploring the seabed in international waters for valuable minerals.
Many countries are loath to adopt new rules that would constrain them.

And so, the negotiations need to answer critical questions.
How will marine protected areas be chosen?
How much of the ocean will be set aside as sanctuaries?
Will extraction of all marine resources be prohibited from those reserves — as so-called no-take areas — or will some human activity be allowed?
Not least, how will the new reserve protections be enforced?

Russia, for instance, objected to using the phrase “long term” conservation efforts in the document that came out of the latest negotiations in July, instead preferring time-bound measures.
The Maldives, speaking for island nations, argued that new treaty negotiations were urgent to protect biodiversity.

Several countries, especially those that have made deals with their marine neighbors about what is allowed in their shared international waters, want regional fishing management bodies to take the lead in determining marine protected areas on the high seas.
Others say a patchwork of regional bodies, usually dominated by powerful countries, is insufficient, because they tend to agree only on the least restrictive standards.
(The United States Mission to the United Nations declined to comment.)

The new treaty negotiations could begin as early as 2018.
The General Assembly, made up of 193 countries, will ultimately make the decision.

A hint of the tough diplomacy that lies ahead came last year over the creation of the world’s largest marine protected area in the international waters of the Ross Sea.
Countries that belong to the Commission for the Conservation of Antarctic Marine Living Resources, a regional organization, agreed by consensus to designate a 600,000-square-mile area as a no-fishing zone.
It took months of pressure on Moscow, including an intervention by John F. Kerry, then the United States secretary of state.

The discussions around marine protected areas on the high seas may also offer the planet a way to guard against some of the effects of global warming.
There is growing scientific evidence that creating large, undisturbed sanctuaries can help marine ecosystems and coastal populations cope with climate change effects, like sea-level rise, more intense storms, shifts in the distribution of species and ocean acidification.

Not least, creating protected areas can also allow vulnerable species to spawn and migrate, including to areas where fishing is allowed.

For over 4000 years fishermen have been catching tuna during their migration through the Mediterranean. During the antiquity they were hailed as the "manna of the oceans".
We take a look at the long journey of the tuna to its mating grounds and witness their struggles including massive amounts of hunters and the strong presence of fishing boats.
 
Fishing on the high seas, often with generous government subsidies, is a multibillion-dollar industry, particularly for high-value fish like the Chilean sea bass and bluefin tuna served in luxury restaurants around the world.
Ending fishing in some vulnerable parts of the high seas is more likely to affect large, well-financed trawlers.
It is less likely to affect fishermen who do not have the resources to venture into the high seas, said Carl Gustaf Lundin, director of the global marine program at the International Union for Conservation of Nature.
In fact, Mr. Lundin said, marine reserves could help to restore dwindling fish stocks.
High-seas fishing is not nearly as productive as it used to be.
“It’s not worth the effort,” he said.
“We’ve knocked out most of the catches.”

Currently, a small but growing portion of the ocean is set aside as reserves.
Most of them have been designated by individual countries — the latest is off the coast of the Cook Islands, called Marae Moana — or as in the case of the Ross Sea, by groups of countries.
A treaty, if and when it goes into effect, would scale up those efforts: Advocates want 30 percent of the high seas to be set aside, while the United Nations development goals, which the nations of the world have already agreed to, propose to protect at least 10 percent of international waters

Why is such a treaty necessary?
At the moment, a variety of regional agreements and international laws govern what is permitted in international waters.
The countries of the North Atlantic must agree, by consensus, on what is allowed in the high seas in their region, for instance, while the International Seabed Authority regulates what is allowed on the seabed in international waters, but not much more.

That patchwork, conservationists argue, has left the high seas open to pillage.
Enforcement is weak.
Elizabeth Wilson, a project director at the Pew Charitable Trusts, wrote in a recent paper that they “lack the coordination to protect and conserve their immense but fragile biodiversity.”
Pew offers a list of fragile high-seas ecosystems that should be protected.
At the top of the list is the Sargasso Sea in the middle of the Atlantic Ocean, which is under increasing pressure from fishing trawlers, Ms. Wilson writes, and home to 100 species of invertebrates, 280 species of fish and 23 types of birds.

Why it's not surprising that ship collisions still happen


From BBC by Chris Baraniuk

The ocean may be huge, and navigation technology may be advanced – but the conditions are still in place for ocean collisions like the one between a tanker and US navy destroyer this week.
What can be done to prevent future disasters?

It happened in the middle of the night, off the coast of Malaysia.
A large tanker filled with nearly 12,000 tonnes of oil smashed into the side of US Navy destroyer the John S McCain, named after the father and grandfather of US senator John McCain.

Ten sailors from the McCain are missing but the vessel is now at Changi Naval Base in Singapore. It’s an extraordinary and tragic collision, but all the more-so because a remarkably similar accident happened just two months ago.
The USS Fitzgerald was struck by a large container ship off the coast of Japan. Seven US sailors died.

The ships involved in these recent incidents are large and well-fitted with radar and navigation systems.
There are also GPS tracking, automatic identification systems (AIS) and radio communications.
How could such collisions have happened?
And what can be done to prevent them happening again?

“Provided you are keeping a radar watch and a visual lookout, then collisions are avoidable,” says Peter Roberts, directory of military sciences at the Royal United Services Institute (RUSI).
We don’t know the details of the latest collision, but sometimes it is left to the instruments to warn of impending collision, rather than members of the crew.
Roberts says he has travelled on commercial ships where sometimes there is no-one on the bridge at all.
“An alarm is going off on the radar and they’re reliant on that alarm waking whoever is on watch,” he says. Still, two major accidents involving navy ships in as many months is extraordinary, he adds. “It’s very, very rare,” he says.
It could, of course, just be a deeply unfortunate coincidence.

But some are asking whether foul-play or sabotage was involved – were navigation systems hacked to increase the likelihood of a collision, for instance?
There has been at least one report of potential GPS position spoofing affecting ships in the Black Sea in recent months, which has led to concern among a few observers that some nation states may be hacking ships in an effort to throw them off course.
There is no evidence yet for this being a factor in the USS Fitzgerald or John S McCain cases – despite the conspiracy theories floating around the web.
But Roberts says that the scenario is worth considering.
“You’ve got to keep every possibility open at the moment,” he says.

It’s important to remember that large ships do get involved in accidents from time to time, even though the cases are not always newsworthy enough to attract coverage.
Just a day or two before the McCain accident, for example, two cargo ships collided off the coast of Fujian in China and there are reports of seafarers having been killed as a result.
When such accidents occur, investigators often find that human error was the ultimate cause rather than anything more nefarious, says Henrik Uth at Danish firm Survey Association, a maritime surveyor contracted by insurers of ships.
He adds that his firm’s own investigations have found many instances in which the crew has actually helped to avoid dangerous near-misses.
“It’s easy to blame the captain for when it goes wrong, but we tend to forget to compliment him for all the times he saved the vessel from imminent danger,” says Uth.

It’s not just collisions that threaten ships and their crew, either.
Right now, a British ship, the MV Cheshire – loaded with many thousands of tonnes of fertiliser – is on fire and has been drifting in seas near the Canary Islands for days.
The crew had to be airlifted to safety.

The seas are becoming more and more crowded, and the global number of commercial ships continues to grow.
According to the UK government, there were around 58,000 vessels in the world trading fleet at the end of 2016.
The size of the fleet, if measured by weight, has doubled since 2004.

So are collisions only going to become more frequent?
Uth suggests that since the financial crisis of 2008, many shipping companies have faced tighter margins and may have underinvested in crews as a result.
“They need to find the right crew and retain them,” he explains.
“The crew has to get to know the vessel because it is a sophisticated piece of hardware.”
And on any large ship, a typical crew often comprises a mix of different languages, nationalities and safety cultures, he adds, making the job of keeping the vessel safe all the trickier.
One rising worry is modern sailors’ reliance on technology, says former navigator Aron Soerensen, head of maritime technology and regulation at the Baltic and International Maritime Council (Bimco).
“Instead of looking at the instruments, you have to look out the window to see how the situation actually evolves,” he explains.
“Maybe today there’s a bit of a fixation on instruments.”

But he points out that maritime organisations have tried to come up with ways of reducing the likelihood of collisions happening.
One idea he mentions is the separation of traffic – neatly co-ordinating streams of vessels travelling through a busy strait, for example, by moving them into distinct lanes heading in the same direction.
The first such “traffic separation scheme” was set up in the Dover Strait in 1967 and there are now around 100 worldwide.
It’s in everyone’s interests to avoid a collision.
Not least because under international regulations, both parties share liability for such accidents. In other words, captains are obligated to avoid colliding with another vessel even if their own ship has every right to be at its current position.

While the recent accidents are troubling, there is good news from the industry too, Uth says.
He points out that the number of total losses – for example when a ship sinks – has been falling year-on-year recently.
According to data from insurance firm Allianz, there were 85 total losses of large ships recorded in 2016, a fall of 16% on the previous year.
Of all 85, just one total loss was the result of a collision.
There’s no doubt that technology has in many ways contributed to safety in the shipping industry – but life as a seafarer remains dangerous.
As more and more large vessels plough the world’s seas, the need to captain these behemoths has not evaporated, rather, it has grown ever more pressing.

Russian tanker sails through Arctic without icebreaker for first time

A Russian tanker has carried a cargo from Hammerfest in Norway to Boryeong in South Korea in 22 days, about 30% quicker than the conventional southern shipping route through the Suez Canal

From The Guardian by Patrick Barkham

Climate change has thawed Arctic enough for $300m gas tanker to travel at record speed through northern sea route

A Russian tanker has travelled through the northern sea route in record speed and without an icebreaker escort for the first time, highlighting how climate change is opening up the high Arctic.


The $300m Christophe de Margerie carried a cargo of liquefied natural gas (LNG) from Hammerfest in Norway to Boryeong in South Korea in 22 days, about 30% quicker than the conventional southern shipping route through the Suez Canal.

The tanker was built to take advantage of the diminishing Arctic sea ice and deliver gas from a new $27m facility on the Yamal Peninsula, the biggest Arctic LNG project so far which has been championed by the Russian president, Vladimir Putin.

The Christophe de Margerie carried a cargo of liquefied natural gas from Hammerfest in Norway to Boryeong in South Korea in 22 days.

On its maiden voyage, the innovative tanker used its integral icebreaker to cross ice fields 1.2m thick, passing along the northern sea section of the route in the Russian Arctic in a record six-and-a-half days.

“It’s very quick, particularly as there was no icebreaker escort which previously there had been in journeys,” said Bill Spears, spokesperson for Sovcomflot, the shipping company which owns the tanker.
“It’s very exciting that a ship can go along this route all year round.”

Environmentalists have expressed concern over the risks of increased ship traffic in the pristine Arctic but Sovcomflot stressed the tanker’s green credentials.
As well as using conventional fuel, the Christophe de Margerie can be powered by the LNG it is transporting, reducing its sulphur oxide emissions by 90% and nitrous oxide emissions by 80% when powered this way.
“This is a significant factor in a fragile ecosystem,” said Spears.


The northern sea route between Siberia and the Pacific is still closed to conventional shipping for much of the year.
But the Christophe de Margerie, the first of 15 such tankers expected to be built, extends the navigation window for the northern sea route from four months with an expensive icebreaker to all year round in a westerly direction.

In the route’s busiest year so far, 2013, there were only 15 international crossings but the Russian government predicts that cargo along this route will grow tenfold by 2020.
This link with the Pacific reduces its need to sell gas through pipelines to Europe.
“There has been a steady increase in traffic in recent years,” said Spears.
“There’s always been trade along this route but it’s been restricted a lot by the ice. It’s exciting that this route presents a much shorter alternative than the Suez route. It’s a major saving.”

Simon Boxall, an oceanographer at the University of Southampton, said that shipping companies were making a “safe bet” in building ships in anticipation that the northern sea route will open up.
“Even if we stopped greenhouse emissions tomorrow, the acceleration in the loss of Arctic ice is unlikely to be reversed,” he said.
“We’ve been able to sail through the north-west passage for several years now but the northern passage, which goes past Russia, has opened up on and off since 2010. We’re going to see this route being used more and more by 2020.
“The irony is that one advantage of climate change is that we will probably use less fuel going to the Pacific.”

While sea ice in the Arctic grows and shrinks with the seasons, there is an overall declining trend, as north pole has warmed roughly twice as fast as the global average.
In March 2017, the annual maximum extent of Arctic sea ice hit a record low for the third straight year, according to the US National Snow and Ice Data Centre.

The extent of Arctic ice fell to a new wintertime low in March this year after freakishly high temperatures in the polar regions, and hit its second lowest summer extent last September.

The shipping forecast: a map of Britain's splendid isolation


From Bigthink by Frank Jacobs


The Shipping Forecast is quite possibly the most British thing ever.

The general synopsis at midday: High west Sole 1028 expected east Sole 1019 by midday tomorrow. Low southern Portugal 1010 losing its identity.
The area forecasts for the next 24 hours.
Viking, North Utsire: Northwesterly 4 or 5, occasionally 6 at first. Moderate or rough. Occasional rain. Good, occasionally poor.

The Shipping Forecast is quite possibly the most British thing ever.
It’s quirkier than cricket, defiantly old-fashioned and ceremonial, and as reassuringly regular as Big Ben (1).
Produced by the UK’s Meteorological Office, it's broadcast four times a day by BBC Radio Four.

But it is more than mere maritime meteorology.
For over 90 years, the Shipping Forecast has been a punctual reminder of Britain’s island status – a declaration of geopolitical detachment expertly disguised as a weather bulletin. Splendid isolation masquerading as shifting isobars (2). 
And as such, one of the greatest examples of classic British understatement.
If that isn’t an oxymoron.
South Utsire: Northwesterly 5 or 6. Moderate or rough. Occasional rain. Good, occasionally poor. Forties, Cromarty: Northwest 4 or 5, occasionally 6 at first. Moderate, occasionally rough in northeast Forties. Rain or drizzle, fog patches developing. Moderate or good, occasionally very poor.
Listing the weather conditions in 31 sea areas surrounding the British Isles, the Shipping Forecast is read out at 5.20 am, 12.01 pm, 5.54 pm and 00.48 am.
The first and last broadcasts of the day also include reports from additional weather stations and inshore waters forecasts.
The last one also includes an outlook for next-day weather across the UK itself.
Forth, Tyne, West Dogger: Westerly or northwesterly 4 or 5, occasionally 6 at first. Slight or moderate. Fair. Good. East Dogger, Fisher, German Bight: Northwesterly 5 or 6. Moderate, occasionally rough. Fair then occasional rain, fog patches later. Moderate or good, occasionally very poor later.
Much of the Forecast’s charm derives from the – literally – outlandish names of the sea areas listed in the bulletin. The names derive from sandbanks (e.g. Dogger, Bailey), estuaries (Forth, Thames, Shannon), islands or islets (Wight, Rockall, Utsire), towns (Dover), or other geographic features (e.g. Malin Head, Ireland’s northernmost point).
Humber, Thames: West or northwest 4 or 5. Slight or moderate. Mainly fair. Good. Dover, Wight, Portland, Plymouth: Variable 3 or 4. Slight. Fair. Good.
One is named FitzRoy, after the captain of HMS Beagle, Britain’s first professional weatherman and the founder of the Met Office.
The southernmost region, Trafalgar is only mentioned standard in the last forecast of the day.
The regions are always listed in the same order, starting north with Viking, between Scotland and Norway, and then proceeding in a roughly clockwise direction:

Viking, North Utsire, South Utsire, Forties, Cromarty, Forth, Tyne, Dogger, Fisher, German Bight, Humber, Thames, Dover, Wight, Portland, Plymouth, Biscay, Trafalgar, FitzRoy, Sole, Lundy, Fastnet, Irish Sea, Shannon, Rockall, Malin, Hebrides, Bailey, Fair Isle, Faeroes and Southeast Iceland.
Biscay: Northeast 4 or 5, increasing 6 at times. Slight or moderate. Fair. Good. Southeast Fitzroy: Northerly or northeasterly 5 or 6, occasionally 7 at first. Moderate or rough. Showers. Good.
The map shown here also lists the coastal weather stations mentioned in the Shipping Forecast:

(1) Tiree, (2) Stornoway, (3) Lerwick, (4) Fife Ness, (5) Bridlington, (6) Sandettie Light Vessel Automatic, (7) Greenwich Light Vessel Automatic, (8) Jersey, (9) Channel Light Vessel Automatic, (10) Scilly Automatic, (11) Valentia, (12) Ronaldsway, (13) Malin Head

A few others are mentioned only in the 00:48 broadcast: Boulmer, Milford Haven, Liverpool Crosby, Machrihanish Automatic, among others.
Northwest Fitzroy: Northeasterly 4 or 5 becoming variable 3 or 4. Moderate. Rain later in west. Good. Sole: Variable 3 or 4, becoming southerly 4 or 5 in west. Slight or moderate. Rain later in west. Good.


One of the Shipping Forecast’s attractions to others than fishermen and sailors is its poetic effect, the result of its very strict format and an arcane terminology, only intelligible to the initiated.

Each bulletin begins with exactly the same opening line, and follows the same structure.
Preceded by gale warnings if necessary, a General Synopsis gives the position, pressure in millibars and track of pressure areas.
Then follows the forecast for each of the 31 areas, sometimes with some areas grouped together if they have the same outlook.
Each of these lists wind direction and strength, precipitation if applicable, and visibility (‘good’ for more than 5 nautical miles, ‘poor’ for less than 2 nm, and ‘fog’ for less than 1,000 metres).
The whole thing never exceeds 370 words.
Lundy, Fastnet, Irish Sea: Westerly 4 or 5 at first in east Lundy, otherwise variable 3 or 4. Smooth or slight, occasionally moderate in Fastnet. Fair. Good. Shannon, Rockall: Southerly or southwesterly 4 or 5, occasionally 6 in west. Slight or moderate, becoming moderate or rough. Rain later in west. Mainly good.
The gap between Radio Four’s last programme of the day and the final Shipping Forecast, at 48 minutes past midnight, is plugged with as much as necessary of ‘Sailing By’, an orchestral piece by Ronald Binge, otherwise famous for his arrangements for Mantovani.
The repetitive waltz helps sailors find the right frequency.
For the many landlubbers tuning in to the last Shipping Forecast of the day, the cozy number signals that it’s almost time to turn in for the night.
Malin: Southwest 4 or 5. Slight or moderate. Mainly fair. Good. Hebrides: West 5 or 6, backing southwest 4 or 5. Moderate. Occasional drizzle. Good, occasionally poor.
Thousands use the day’s last forecast as a lullaby.
Adding to its hypnotic, soporific effect is the fact that it’s read out at a deliberately slow pace, to allow seafarers to make notes. 
The strange place-names and the weird jargon give the Shipping Forecast a magical shine.
And perhaps they give the thousands tucked away safe in their beds pause to think about those out at sea at that very moment, in the dark, listening to the same bulletin.

The forecast is followed by God Save the Queen, after which it’s exactly 1 am, and BBC World Service takes over.
Bailey: West backing south or southeast 5 or 6, decreasing 4 for a time. Moderate. Occasional rain. Good, occasionally poor. Fair Isle, Faeroes:West or northwest 4 or 5, occasionally 6 at first, becoming variable 3 or 4 at times later. Mainly moderate. Occasional rain, fog patches developing. Moderate or good, occasionally very poor.
The Shipping Forecast has made a huge mark on music, literature and the wider culture. 
 
It inspired songs by Jethro Tull, Manfred Mann’s Earth Band, Wire, Blur, Radiohead, Tears for Fears, British Sea Power, Beck and the Prodigy, among others, and it was used in the opening ceremony of the 2012 London Olympics.
Nobel-prize-winning poet Seamus Heaney wrote a sonnet called ‘The Shipping Forecast’, and British Poet Laureate Carol Ann Duffy mentions “the radio’s prayer” in one of her poems.
The programme is used in books, films, tv series, and has been parodied countless times (once as ‘The Shopping Forecast’, listing UK supermarkets instead of sea regions)

Southeast Iceland: Cyclonic becoming easterly or southeasterly 4 or 5, increasing 6 or 7 later in west. Moderate, occasionally rough. Occasional rain. Good, occasionally poor. Trafalgar: Cyclonic 4 in southeast, otherwise northerly 5 to 7. Slight or moderate in southeast, otherwise moderate or rough. Thundery showers. Good, occasionally moderate.
