The truth about politics and cartography: mapping claims to the Arctic seabed

New Arctic map, with August 2015 Russian claims shown in pale yellow.

From The Conversation

While maps can certainly enlighten and educate, they can just as easily be used to support certain political narratives.
With this in mind, Durham University’s Centre for Borders Research (IBRU) has updated its map showing territorial claims to the Arctic seabed following a revised bid submitted by Russia to the United Nations on August 4.
The decision to release the map was not made lightly.
The map of “Maritime jurisdiction and boundaries in the Arctic region” by IBRU depicts the claims to Arctic seabed resources that have been made, or could potentially be made, by Canada, Denmark, Russia, Norway, and the USA.
In addition, IBRU has also created a simplified map showing the old and new Russian claims from 2001 and 2015 – and the differences between them.

The myth of a “Cold War”

We created our first Arctic map in 2008 to dispel reports that the region was about to erupt in a “new Cold War”.
As the map’s notes explain, nothing could be further from truth.
Since 2001, Arctic states have been engaging in scientific research – often in cooperation with each other – to gather the data that would enable them to make submissions to the Commission on the Limits of the Continental Shelf (CLCS).

Areas in pale yellow are in both claims.

The CLCS is empowered by the UN to assess whether areas of the seabed meet a complicated series of bathymetric and geological criteria which can permit coastal states to claim exclusive rights to the non-living resources of the seabed, beyond 200 nautical miles from coastal baselines.
The original Arctic map denoted the maximum claims that could be made given the scientific data that was then publicly available.
The map’s accompanying notes clearly stated, however, that these were hypothetical maximums and that the actual extent of each state’s extended continental shelf would likely be reduced once more data were gathered.
States around the world have been making these submissions, with some 77 filed to date for seas ranging from Oceania to the Caribbean.
The CLCS has reached decisions on about a quarter of them.
In the Arctic, Norway’s submission has been approved, Denmark’s is under review, Canada’s is being prepared, and Russia has just deposited a revised submission after its original 2001 submission was returned with a request for more detailed scientific evidence.
The United States is the sole Arctic state frozen out of the process because it has failed to ratify the United Nations Convention on the Law of the Sea.

The new Russian claim adds two new areas and subtracts one from the original 2001 claim.
In total, it adds about 103,000 square kilometres to what had been a claim of 1,325,000 square kilometres.
The new Russian claim crosses into the Canadian and Danish sides of the North Pole for the first time. While this may have symbolic impact (especially for Canadians and Danes), it has no legal significance.
In short, little is actually happening on the international seabed – in the Arctic or elsewhere – other than states using science to claim the limited economic rights that are reserved for them by international law.
These filings should therefore be celebrated as reaffirmations of the will toward peace and stability, rather than feared as unilateral acts of aggression.
All too often, however, states’ CLCS filings have been interpreted as territorial “land grabs” (or, more correctly, “sea grabs”).
The most recent Russian claim has been met with a predictable round of defensive sabre rattling.
The IBRU map may inadvertently aid this impression.
Solid lines and bright colours imply that vast areas of ocean are being claimed by individual states as sovereign territory, while overlapping areas appear as spaces where conflict already exists.
News stories that reprint the map rarely include the notes that explain what its colours and shadings actually mean.
The medium of the map – which appears to communicate a world of states “owning” territory and keeping others out – has in some senses overtaken the message of states working together.

The Russians are coming … or are they?

In the context of Russia’s expansion into non-Arctic territories (notably in Crimea), the revised Russian claim has struck the media as another tale of Russian expansion. Provocative headlines noted that, with the filing, “Russia claims North Pole for itself” in a “Move to seize oil and gas rights”.
Having drawn the revised map, IBRU had a difficult decision: Do we issue a new map and potentially add fuel to this misleading narrative or do we wait for the story to die down so that lawyers, diplomats and scientists can work quietly with the data?
We soon reached a conclusion that, even when they misinform, maps provide an opportunity for education.
Therefore, IBRU chose to release not just the revised version of the general map, but also the second map showing the difference between the two Russian claims.
Recent cartographic theorists have stressed that maps are not the static representations that they purport to be.
Rather, they are living documents that are remade with each reading.
In one reading, the IBRU Arctic map may “prove” that there is a “scramble for the Arctic”.
But the map may also be read as testament to the world’s commitment to the rule of law and the orderly settlement of disputes.
The stories within – and about – the IBRU Arctic map illustrate not just how we think about the Arctic and its resources, but also how we think about the map as a tool of science, politics, and law.

USCG: Guidance on the use of Electronic Charts and Publications

Official nautical raster charts from original material coming from international Hydrographic Offices displayed online with mobile marine planning applications (W4D screenshot) and GeoGarage platform

The US Coast Guard has issued a Navigation and Vessel Inspection Circular (NVIC) providing USCG marine inspectors and the maritime industry with uniform guidance regarding what the Coast Guard policy regarding use of electronic charts and publications in lieu of paper charts, maps, and publications.

As per reference, US flagged vessels may maintain in electronic format the navigation publications required by 33 C.F.R § §
  • 164.33 (Charts and publications),
  • 164.72 (Navigational-safety equipment, charts or maps, and publications required on towing vessels) and 161.4 (Requirement to carry the rules)
  • and SOLAS Chapter V Regulation 27 (Nautical charts and nautical publications). 

The following guidance applies to US flagged vessels subject to US domestic chart 9or map) and publication carriage requirements codified in Titles 33 and 46 of the C.F.R and provides a voluntary equivalency to comply with those requirements

Extracts :

"Due to the current state of technology, the Coast Guard believes that official electronic charts provide substantially more information to the mariner, and therefore may enhance navigational safety beyond that of official paper charts.
Official electronic charts, when displayed on electronic charting systems (with integrated systems such as Electronic Positing-Fixing Devices, Automatic Identification System, gyro, radar), can provide the mariner with substantially more navigational information than a paper chart. These enhancements better facilitate voyage planning and monitoring and thus may reduce the potential for marine accidents."

New Air Force satellites launched to improve GPS

 Final 12th GPS II satellite goes into orbit as Air Force gets ready for GPS III

From Techcrunch

Last Friday, the United Launch Alliance (ULA) successfully launched a Boeing-built satellite into orbit as part of the U.S. Air Force’s Global Positioning System (GPS).

This $131 million satellite was the final addition to the Air Force’s most recent 12-satellite GPS series, known as the Block IIF satellites.

GPS satellites are operated by the Air Force and provide global positioning, navigation and timing services both for the military and civilian users.
We can all access GPS from our phones because of this very constellation.

Back in 1978, the first GPS satellite was launched into orbit.
Since then, the Air Force has improved their satellite design and released new versions of GPS satellites in blocks.
Starting with Block I, the Air Force has moved through Block IIA, Block IIR, Block IIR-M, and today they’ve completed the launch of their Block IIF series.

While only 30 GPS satellites are currently operational, 50 have been launched in total.
The most recent group of Block IIF satellites were launched between May of 2010 and today.

Col. Steve Whitney, the director of the Global Positioning System Directorate, said that the last leg of launches had “one of the most aggressive launch schedules of the last 20 years.”
There were 7 Block IIF satellites launched in just over 21 months.


The GPS Block IIF satellites were launched to improve the accuracy of GPS. Col. Steve Whitney, the director of the Global Positioning System Directorate, said that before the Block IIF series, the accuracy of GPS could be off by 1 meter.
With the new Block IIF satellites in place that error is down to 42 centimeters.

The change won’t mean much to the average civilian, but it could mean the difference between life and death for the military who uses GPS to guide munition to specific targets.

In order to make room for today’s satellite, the Air Force will move one of the older Block IIA satellites that was launched in 1990 out of its orbit.
Impressively, the satellite is still operational and will continue to serve the GPS constellation as a back-up satellite.

Now that Block IIF is up and running, the Air Force will shift its focus to the next series of Block III satellites for the GPS-3 constellation.
Block III satellites will continue to improve the accuracy and reliability of GPS navigation and will have upgraded anti-jamming and security capabilities for military signals.

Maintaining an up-to-date fully functioning GPS is pertinent to national security.
For these reasons, selecting a company to launch these assets is an important decision.
There’s been some controversy recently over which company (ULA or SpaceX) should launch the Air Force’s next block of satellites.
The decision has not yet been made.

The first GPS 3 satellites are scheduled to be launched in 2018.

Watch all of 2015’s weather in super high-def

 This visualisation, comprised of imagery from the geostationary satellites of EUMETSAT, NOAA and the JMA, shows an entire year of weather across the globe during 2015, with audio commentary from Mark Higgins, Training Manager at EUMETSAT.

From ClimateCentral by Brian Kahn 

Another year of wild weather is behind us. But thanks to EUMETSAT, you can now relive it in amazing high-definition video from space.
The new visualization uses geostationary satellite data from EUMETSAT, the Japan Meteorological Agency and the National Oceanic and Atmospheric Administration to stitch together 365 days of data into one stunning highlight reel of 2015’s weather.
And what a year it was. You’ll definitely want to keep your eye on the tropics throughout the animation as the northern hemisphere set a record for the most major tropical cyclones to form in a year.
Around the 6:30 mark, you can see the evolution of Hurricane Joaquin, the strongest Atlantic hurricane of 2015. It went from a tropical depression in late September to a Category 4 storm that battered the Bahamas and menaced the East Coast before steering all the way across the Atlantic and plowing into the U.K.

 

The transition of Hurricane Joaquin near the Bahamas to an extratropical storm that hit the U.K.
Hurricane Patricia became the strongest hurricane ever recorded in October and at the 6:55 mark, you can see it quickly slam into Mexico’s west coast before heading inland to inundate parts of Texas.

But beyond the highlights, there’s also yearly the ebb and flow of weather on our fair planet. During the southern Amazon’s rainy season, which last from December-April, you can see clouds pop up almost daily to spread rains across the region.
Clouds become far less plentiful during the region’s dry season.

And more broadly, you can see weather patterns flow across continents and oceans.
Today’s storm in the Southeast U.S. is next week’s rain in Spain.
By putting together a global view of our planet, EUMETSAT’s video shows how our atmosphere is the common tie that binds humanity together.
There have been a few things updated since last year’s version.
For one, EUMETSAT has cranked the resolution to 4K for truly epic detail.
And more importantly, the quality of satellites in space has improved.
Both Japan and EUMETSAT launched new satellites last year that have higher resolutions than their predecessors. The National Oceanic and Atmospheric Administration plans to launch a new high resolution geostationary satellite this year, adding even more detailed coverage of the planet.
That’s good news if you want an even sharper 4K experience or improved forecasts.
And if you want both, well, then life is really good.

A plastic ocean

A Plastic Ocean is an adventure documentary shot on more than 20 locations over the past 4 years. Explorers Craig Leeson and Tanya Streeter and a team of international scientists reveal the causes and consequences of plastic pollution and share solutions.



This film directed by Emily V. Driscoll, is an award-winning short documentary that follows NYC sci-artist Mara G. Haseltine as she creates a sculpture to reveal a microscopic threat beneath the surface of the ocean.
During a Tara Oceans expedition to study the health of the oceans, Haseltine finds an unsettling presence in samples of plankton she collected.
The discovery inspires her to create a sculpture that shows that the microscopic ocean world affects all life on Earth.
