Likely impacts of proposed 3D-seismic surveys to the terrain, permafrost, hydrology, and vegetation in the 1002 Area, Arctic National Wildlife Refuge, Alaska. A white paper by Alaskan scientists detailing 10 issues regarding conditions in 1002 Area and the likely cumulative effects of 3D-seismic surveys. Read the report

The Raster Circumpolar Arctic Vegetation Map (Raster CAVM) maps 16 vegetation types, glaciers, saline water, and freshwater at 1-km resolution. It builds on the strengths of the original CAVM, using the same legend, extent and projection, while providing a finer spatial resolution, raster format, and improved mapping of Arctic vegetation.
