Early Radar Maps of Antarctica Digitized

Nature: “Glaciologists will soon have a treasure trove of data for exploring how Antarctica’s underbelly has changed over nearly half a century. An international team of researchers has scanned and digitized 2 million records from pioneering aeroplane radar expeditions that criss-crossed the frozen continent in the 1960s and 1970s. […] The digitized data extend the record of changes at the bottom of the ice sheet, such as the formation of channels as Antarctica’s ice flows, by more than two decades.” (Modern radar mapping of Antarctica apparently only began in the 1990s.)
