NSDIC - ICE SHEETS TODAY NATIONAL SNOW AN ICE DATA CENTER MAPS, CHARTS, REPORTS!
Excerpts: After setting records in December and January for melt extent in the 47-year satellite record, melt extents dropped abruptly by early February when conditions over the Antarctic Peninsula cooled. Overall, the number of melt days exceeded the 1991 to 2020 long-term average by approximately 10 days in the Larsen C Ice Shelf area, 15 days in the Fimbul Ice Shelf area, and over 30 days along the eastern side of the Amery Ice Shelf. Also notable were above average melt days in the West, Shackleton, and Totten Ice Shelf areas. The Sulzberger and Ross Ice Shelves were among the few areas with below average melt days for the austral summer season. Extensive ponding apparent in January in satellite images on the Larsen B remnant, known as Scar Inlet Ice Shelf, and northern Larsen C, all refroze in February; however, ponding and some surface melt flow were still visible on the Amery and Roi Baudouin Ice Shelves into March, although with a frozen surface at that point.
