The US National Ice Center refixed all 33 tracked Antarctic icebergs on 13 August. Eight moved more than 30 km in six days. Nine did not move at all.
At one emperor penguin colony in Marie Byrd Land the sea ice season has gone from 322 days a year to 207, and it has shortened at both ends at once.
COMNAP lists 114 Antarctic facilities run by 31 nations. 103 are in use, only 44 stay open through the winter, and just 83 are called stations.
An iceberg knocked the Mertz Glacier Tongue off in 2010 and grounded nearby. Summer sea ice at Cape Denison went from 4 percent to 54 percent.
In winter the furthest point on the Antarctic ice sits 1,815 km from the nearest facility that stays open, and the three closest all lie the same way.
D15A, at 3,037 square kilometres, is the largest iceberg on the US National Ice Center list. It holds a quarter of all tracked Antarctic berg area.
Emperor Island in Marguerite Bay held emperor penguins from 1948 to about 2009. Its sea ice season is 75 days shorter, and it is shorter at one end.
Antarctic science is world-class and almost entirely invisible. Here is what we are building, and why the model is Global Forest Watch rather than an academic archive.
Antarctic sea ice stands at 16.085 million square kilometres, the 4th lowest reading for 9 August in a 48 year satellite record. What that number means.
Antarctica has 729 known penguin breeding sites. Three adjacent slices of longitude hold 510 of them, and the reason is a species list, not a survey bias.
Concordia sits 3,233 metres up on Dome C, holds 80 people in summer and 0 visitors in winter. Its sun rises again this week after 104 days of night.
Web Mercator clips at 85 degrees and the South Pole is undefined in it. Here is why every web map fails on Antarctica, and the projection that works.
