Description 

            

              

                

                  

                    The spatial data were obtained from the Natural Earth website. The data originated from the 2003-2004 Mosaic of Antarctica.* The data are suitable for making relatively detailed maps of countries and regions and are intended for use at a scale no larger than 1:10,000,000. Attributes were modified to include recnum ID, type, and name. The coordinate system of this data is WGS 1984.
                  

                  

                    *Reflects recent ice shelf collapses digitized from satellite images. Does not include seasonal (winter) ice which extends much farther around the Antarctic continent.
