Sea Ice Remote Sensing Map of Arctic sea ice thickness (April 2015) obtained from CryoSat-2 data (Graphic: Alfred Wegener Institut) Contact: Dr. Stefan Hendricks The inaccessibility and sheer size of sea ice covered regions in the Arctic and Antarctic oceans make satellite remote sensing the only tool that is able to obtain a full picture of sea ice conditions. The [...] based on a radar altimeter that fully maps Antarctic sea ice and Arctic sea ice up to a latitude of 88°N. This coverage is unparalleled in comparison with all previous and existing satellite altimeters
