An Improved Portrayal of the Floor of the Arctic Ocean, Based on a Grid Derived from GEBCO Bathymetric Contours
Digital descriptions of sea floor relief and land topography in the Arctic are useful for scientific and illustrative purposes, however existing public-domain data sets, such as the ET0P05 grid and extracts from the GEBCO Digital Atlas, don’t lend themselves particularly well to visualization and ot...
