Unprecedented springtime retreat of Antarctic sea ice in 2016
During Austral spring 2016 Antarctic sea ice extent (SIE) decreased at a record rate of 75 × 103 km2 day-1, which was 46% faster than the mean rate and 18% faster than in any previous spring season during the satellite era. The decrease of sea ice area was also exceptional and 28% greater than the m...
