2019 – SD 1020, an unmanned surface vehicle (USV) designed by British engineer Richard Jenkins of Saildrone, Inc. in Alameda, CA, completed the first autonomous circumnavigation of Antarctica, sailing 22,000 km (12,000 nmi) through the Southern Ocean in 196 days, from 19 January 2019 to 3 August 2019.
The first women to have any fanfare about their Antarctic journeys were Caroline Mikkelsen who set foot on an island of Antarctica in 1935, [144] and Jackie Ronne and Jennie Darlington who were the first women to over-winter in Antarctica in 1947. [145] The first woman scientist to work in Antarctica was Maria Klenova in 1956. [146]
A sea-level rise of 3.3 m (10 ft 10 in) would occur if the ice sheet collapses, leaving ice caps on the mountains, and 4.3 m (14 ft 1 in) if those ice caps also melt. [101] Isostatic rebound may contribute an additional 1 m (3 ft 3 in) to global sea levels over another 1,000 years. [ 100 ]
The Heroic Age of Antarctic Exploration was an era in the exploration of the continent of Antarctica which began at the end of the 19th century, and ended after the First World War; the Shackleton–Rowett Expedition of 1921–1922 is often cited by historians as the dividing line between the "Heroic" and "Mechanical" ages.
