The new grid is on a 500 meter spacing, revealing much greater details of the Arctic seafloor than IBCAO Version 1.0 (2.5 km) and Version 2.0 (2.0 km). The area covered by multibeam surveys has increased from ~6 % in Version 2.0 to ~11% in Version 3.0. The compilation of IBCAO Version 3.0 is described in a Geophysical Research Letter article available for download.

Most interesting feature is the Lomonosov Ridge which splits the Arctic basin in half. Denmark and Russia are trying to find evidence showing the ridge is a extension of their continental shelf. This would allow to further expand their rights to seabed resources.

New claims submitted to the UN will appear here. You may want to check out latest submission by Denmark claiming a huge part of Southern Greenland conflicting with Canadian claims.
