American and Canadian scientists are background sail this summer to map the Arctic seafloor and gather data to help define the external limits of the continental shelf.

Each coastal nation may implementation sovereign rights over the natural resources of their continental shelf, which includes the seabed and subsoil. These rights include control over minerals, petroleum, and sedentary organisms such as clams, crabs and coral.

Under global law, specifically the Buy Bactrim Online United Nations Convention on the Law of the Sea, every coastal nation automatically has a continental shelf out to 200 nautical miles or to a maritime boundary.

The U.S. Ecological Survey Buy paxil online is the lead science agency for the United States in the 2010 mission. “In this expedition, Canada and the U.S. are working together to delineate the extended continental shelf in the Arctic to better determine where the Convention’s criteria can be met,” said USGS scientist Brian Edwards, chief scientist on the U.S. Coast Guard Cutter Healy.

The Healy will sail August 2 – September 6, 2010, meeting up with the Canadian Coast Guard Ship Louis S. St-Laurent at sea.

The ships will alternately break owing to the Arctic sea ice for each other. The Healy will map the shape of the seafloor by a multibeam echo sounder, and the Louis S. St-Laurent will collect multi-channel seismic reflection and refraction data to determine sediment thickness.

This is the third year the United States and Canada have collaborated in extended continental Buy Plavix Online Pharmacy No Prescription Needed shelf data collection in the Arctic. The United States has non-centrally been collecting single ice-breaker data in the Arctic since 2003 in furtherance of the U.S. Extended Continental Shelf Project.

“The Arctic Ocean is an area of fantastic interest for science, resource conservation, and possible economic development,” said USGS scientist Deborah Hutchinson. “Because there is an area with considerable overlap between the U.S. and Canadian extended continental shelves, it makes sense to share data sets and work together in the remote and challenging No prescription levitra environments of the Arctic Ocean.”

“This is the last year working in the Canada Basin north of Alaska, and in 2011, we’ll collect data together with Canada in the area north of the Canada Basin around the Alpha Crumple,” said USGS scientist Jonathan Childs, who is leading the Seismic Data Operations Team for the 2010 mission.

Research is coordinated by the U.S. Extended Continental Shelf Task Break down, a government-wide group headed by the U.S. Department of State.
