IBRU releases new Arctic map with sea ice changes
International Boundaries Research Unit (IBRU) of Durham University has released a new version of its widely used Arctic map. The maps may be found at: https://www.dur.ac.uk/ibru/resources/arctic/.
IBRU’s original Arctic map, first released in 2008 and revised several times since, was a landmark product that assimilated a variety of bathymetric (ocean depth) and political data to depict both hypothetical and jurisdictional boundaries in the Arctic Ocean. The map has been reproduced and adapted widely by news organisations and policy advocates and remains a unique resource for anyone seeking a comprehensive understanding of Arctic maritime politics.
The new map builds on the original map but has several new features that focus on current significant changes in the Arctic: the claiming of mineral rights to the outer continental shelf and the decline in seasonal sea ice extent due to regional and global climate change.
