This is what happens when you crowdfund an awesome marine park

Help turn an area the size of France into the world’s first nation-wide marine sanctuary
 and reverse the oceans’ losses from industrial fishing.

The island nation of Palau may be small — 177 square miles, to be exact — but it is not afraid of making big unprecedented moves when it comes to its fish.
In February, the Micronesian country banned all commercial fishing in its waters, a major first for marine sanctuaries.
The resulting protected area is about the size of France, and encompasses some of the more pristine oceans in the world.

The only problem: How to fund it?

You probably know that marine protected areas are great, but they cost a lot of money up front.
And when Palau President Remengesau announced the reserve, the country had exactly one boat with which to patrol the 230,000 square-mile-wide swath of sea.
So the Palauans did what all spunky and cash-strapped creators are doing these days — they started a crowdfunding campaign.
The Indiegogo project, dubbed “Stand with Palau,” was launched in July and wrapped up this month, having exceeded its goal of $100,000 with some 583 total donors pitching in.
The money will be spent on more boats, monitoring drones and buoys, and the staff to run them.

As marine biologist David Shiffman points out at Scientific American, this is a big and weird first for ocean conservation:
“This is the first time a nation-state has started a marine conservation crowdfunding campaign,” says Daniel Kachelriess, the outreach coordinator for Stand with Palau. “The money raised through the campaign will directly support the implementation of the [Palau] National Marine Sanctuary. It is really about fleshing out the next steps — especially in regard to data collection, monitoring and enforcement framework — and making sure the marine sanctuary is implemented in a way that is on the medium term economically and environmentally sustainable,” he says.

Who knows if this is a viable funding option for other aspiring marine sanctuaries.
It might be the Potato Salad of crowdfunded conservation projects — a unrepeatable miracle.
Or it might be that the day is near when, in addition to funding indie documentaries and slick eco-gadgets, you can back Yellowstone’s new kickstarter initiative and get that sick grizzly poster as a bonus.


If nothing else, Palau just proved that, under the right conditions, private citizens can scrape together some serious cash for the cause.

Copernicus Sentinel-1 : making our seas safer


Wave monitoring
Ships, oil platforms and offshore wind farms are threatened by rough seas.
Information provided by radar satellites can support the detection and forecast of extreme wave heights.

From ESA

Within the first days of its operational life, the Sentinel-1A satellite has provided data for marine services in the Arctic.

During the first week of the satellite’s operational data supply, experts from the Technical University of Denmark and the Danish Meteorological Institute working under the Horizon 2020 MyOcean Follow-On project used the data to alert vessels on marine ice conditions.


Sentinel-1 delivers radar imagery for numerous applications.

Images acquired over the ocean are essential for generating timely maps of sea ice for safe passage as well as for detecting and tracking oil spills.
The mission also offers key information on wind and waves in the open sea for shipping and wave-energy applications.
Images acquired systematically over land mean that ground movement barely noticeable in everyday life can be detected and closely monitored.
As well as being a valuable resource for urban planners, this kind of information is essential for monitoring shifts from earthquakes, landslides and volcanic uplift.
Moreover, Sentinel-1 is designed specifically to provide images for rapid response to disasters such as floods and earthquakes. 
The series of MyOcean projects is the pre-operational precursor of the Copernicus Marine Environment Monitoring Service, to be implemented by the European Commission.
Its primary objective is to provide forecasts of the global marine environment and the near-realtime observation data necessary for forecast models.

Since Sentinel-1A data started to become free and accessible earlier this month with the satellite entering into its operational phase, the Danish Meteorological Institute began to use the information to improve observations of the polar regions and forecast maritime conditions.

The data are being used to produce ice charts, showing the details of ice conditions in a variety of regions, including the warnings of icebergs drifting in shipping routes.

 Monitoring ice drift
This mosaic of Sentinel-1A data from 10 October 2014 shows ice drift vectors derived from Sentinel-1A scenes acquired on 9 and 10 October (red), along with  MyOcean ice drift forecasts for 10 October (yellow).
The PolarView browser allows the visualisation of Copernicus marine core service MyOcean forecasts, as well as observational data from a large number of satellite data sources.

The first ice chart from Sentinel-1A was produced in demonstration mode in April just weeks after launch, demonstrating the satellite’s capabilities for ice mapping at an early stage.
Now that the satellite is operational, the mission will gradually become the backbone to the regular ice charting of Greenland waters.

 Monitoring icebergs
The capability of Sentinel-1A to detect icebergs during all weather conditions is improving maritime safety. The satellite’s radar gathers information in either horizontal or vertical radar pulses, and colours can be assigned to the different types.
In this image acquired near Greenland’s Jakobshavn Glacier on 26 April 2014, sea ice appearing blue-green can be distinguished from icebergs in pink.

The radar on Sentinel-1 can see through clouds and in the dark, making it the perfect tool for monitoring polar regions that are prone to bad weather and long periods of darkness.

This image is an example of an ice chart from 8 October 2014, with red depicting sea ice cover.

The radar can distinguish between the thinner, more navigable first-year ice and the hazardous, much thicker multiyear ice to help assure safe year-round navigation in ice-covered Arctic and subarctic zones.

The mission also provides continuous sampling of the open ocean, offering information on wind and waves.
This is useful for understanding interactions between waves and currents, forecast iceberg drift and improve efficiency for shipping.
In addition, these observations can be used to track the paths of oil slicks and other pollution.

 Ice charts are the primary means of providing near-realtime ice information to mariners, and are traditionally drawn manually from satellite data. The first Sentinel-1A ice chart was drawn from an image acquired at 10:10 GMT on 26 April 2014.

“There are a lot of expectations for Sentinel-1,” said Leif Toudal Pedersen, from the Danish Meteorological Institute.
“This mission will be the backbone of future ice charting and ice service provision, as well as sea ice science development.”

User-friendly, near-realtime access to Sentinel-1 data for marine users in polar regions is provided by PolarView and the DMI Centre for Ocean and Ice.

The current MyOcean-Follow On H2020 project comprises 58 European public and private partners from 28 countries, and is led by Mercator Ocean.

Hydrography - much more than just nautical charts

Rising fraud in the high seas

From Israƫl Defense

First-ever comprehensive review by Windward finds data relied on by finance, shipping and security sectors is increasingly manipulated and unreliable.
This growing manipulation is possible because AIS (Automatic Identification System), originally designed to promote safety at sea, has no validation mechanisms to ensure that the information is accurate.


In the first industry research report to document intentional data manipulation at sea, specialized data and analytics company, Windward, has found that ships worldwide are increasingly manipulating data to conceal their identity, location and destination, undermining the ability to track their activities.

 Submarine emerging in Milan

The report, “AIS Data on the High Seas: An Analysis of the Magnitude and Implications of Growing Data Manipulation at Sea,” finds that the widely-used Automatic Identification System (AIS) data is becoming unreliable, with far-reaching implications from Wall Street commodity traders to global security and intelligence agencies.


The research identifies the top five methods of data manipulation, quantifies the magnitude of this fast-growing trend, and discusses the implications for decision makers.
Some of the key findings:

False Identities on the Rise: There has been a 30% increase in the number of ships reporting false identities over the past two years, with 1% of all ships currently reporting a false identity.

Obscuring Destinations: Ships report their final port of call during only 41% of their voyages, on average, undermining commodity traders and others tracking global commodity flows and supply and demand dynamics.

GPS Manipulation: There has been a 59% increase in the number of ships transmitting incorrect positioning information over the past two years, allowing ships to obscure their actual location. Chinese fishing vessels account for 44% of GPS manipulators.

‘Going Dark’: 27% of ships do not transmit data at least 10% of the time, and large cargo ships shut off their transmissions 24% longer than other ships. 19% of ships that ‘go dark’ are repeat offenders.

AIS Spoofing: AIS can be spoofed, allowing interested parties to create ‘ghost ships’ where none exist.

 Windward provides full visibility on vessels globally, based on their historical, current and projected

There are significant incentives – both criminal and financial – to conceal the real identities, locations or destinations of ships.
This growing manipulation is possible because AIS, originally designed to promote safety at sea, mandates that ships transmit information, but has no validation mechanisms to ensure that the information is accurate.
This off label use of AIS – for tracking ships vs. for safety – has resulted in a growing number of ships hiding their information.

 Off course: Spoof radio signals convinced an online ship tracking service that this fake craft had traveled on a path near Italy that spelled out the hacker term “pwned,” which describes a system that has been compromised by an attacker.

“Global seaborne trade touches nearly every aspect of our lives, with 90% of the world’s trade and most of our commodities transported by sea. And yet, the oceans remain one of the last Wild West frontiers, as this report shows that the data available on what’s happening at sea is increasingly unreliable and manipulated,” said Ami Daniel, co-Founder and CEO of Windward.
“Using this data as-is is a dangerous, and costly, game of chance. With so much at stake, Windward is at the forefront of providing technology that reveals what's truly at sea.”


In the finance industry, taking AIS data at face value may result in a distorted view of commodity flows, a flawed understanding of supply and demand dynamics, and even impact trading models.
These manipulations also undermine security and intelligence communities’ use of watch lists as ships change identities and erase their digital footprints.
As ships grow aware that they are being watched via their AIS transmissions, Windward believes the incentive to manipulate will likely see a sharp increase.

World's largest ship so big it can lift an oil rig takes to the seas

 'Pieter Schelte', largest lifting vessel in the world

From DailyMail by Jonathan O'Callaghan

The biggest vessel in the world has been built by Daewoo Shipbuilding and Marine Engineering in South Korea
Swiss company Allseas commissioned the building of the huge £1.9 billion ($3.1 billion) ship
Called Pieter Schelte, the vessel is almost as long as the Empire State Building and wide as Big Ben's Elizabeth tower
The vehicle will be used to pick up and move oil rigs from one place to another, such as to and from port
Both the legs and main structure of a rig can be carried on the ship and moved simultaneously
It can reach speeds of 14 knots (16.1 mph or 25.9 km/h) and hold a crew of 571 people
Allseas says it will enter offshore operations next year - but an even bigger ship will be built by 2020

The vessel that now holds the title of the world’s biggest ship has taken to the seas for the first time.
Called Pieter Schelte, the behemoth can lift oil rigs right out of the water and move them to new destinations.
It measures a staggering 1,253ft (382 metres) long and 407ft (124 metres) wide, making it almost as long as the Empire State Building is tall and wider than the height of Big Ben.

The biggest vessel in the world has been built by Daewoo in South Korea. Swiss company Allseas commissioned the building of the huge $1.7bn ship.
Both the legs and main structure of a rig can be moved simultaneously

It cost £1.9 billion ($3.1 billion) to build and is powered by 11.2 megawatt engines connected to 13 Rolls Royce 5.5 megawatt thrusters, reports Gizmodo.
Topsides - the upper section of oil rigs - weighing up to 48,000 tons can be lifted by the behemoth, while it will also be able to lift jackets - the legs - of rigs weighing up to 25,000 tonnes.
The ship can then transport both the top and bottom sections of the oil rig simultaneously and take it back to port.
It can even raise and lower itself in the water by 82ft (25 metres) in order to cope with the huge weight demands of moving an oil rig.


Pieter Shelte, which will be operated by Swiss company Allseas, is expected to begin offshore operations next year.
It can reach speeds of 14 knots (16.1 mph or 25.9 km/h) and has space for a crew of 571 people.
When it enters operation it will also be the world's largest pipelaying ship and will be used to construct infrastructure under the sea.
Its pipelay capacity of 2,000 tonnes is double that of the previous record holder, another Allseas ship called Solitaire.
Pieter Shelte will only hold the title of the world’s biggest ship for six years, though; by 2020 Allseas expects to have an even larger vessel in operation to install and move bigger oil rigs.
The Maersk Triple-E also built by Daewoo Shipbuilding still holds the record for the longest ship, though, at 1,312 feet (400 metres).

Called Pieter Schelte (shown) it is almost as big as the Empire State Building.
It will be used to pick up and move oil rigs from one place to another.
It can reach speeds of 14 knots and hold a crew of 571 people.
Allseas says it will enter offshore operations next year.
It measures a staggering 1,253 feet (382 metres) long and 407ft (124 metres) wide, making it almost as long as the Empire State Building is tall and wider than the height of Big Ben.
