This graph also highlights the Feb. 21 record low summer minimum and the Sep. 10 record low winter maximum. Credit: NSIDC/Scott Sutherland It was, by far, the smallest winter maximum we've seen around the continent since record keeping began in ...
However, as of June 20, the day before the start of southern winter, the Antarctic sea ice extent has been setting daily record lows for this time of the year. This graph shows the seasonal cycle of Antarctic sea ice extent, in millions of square kilometres,...
The graph of NSIDC data shows the maximum extent for each September since 1979 in millions of square kilometers. There is a lot of variability from year to year, though the overall trend shows growth of about 0.9 percent per decade. According to arecent studyby sea ice scientists Claire Par...

that a collapse of Antarctic ice is imminent, followed by 3-4 meters of sea-level rise. It’s all based on a model that they took back in time to 14,000 years ago to model “meltwater pulse 1A” seen in the graph below. The only problem is, we aren’t coming out of a...
More than 60% of meteorite finds on Earth originate from Antarctica. Using a data-driven analysis that identifies meteorite-rich sites in Antarctica, we show climate warming causes many extraterrestrial rocks to be lost from the surface by melting into the ice sheet. At present, approximately 5,...
Expendable bathythermograph, wind, and sea surface temperature data collected along 12 crossings of the Drake Passage were analyzed to describe variations in the structure of the antarctic polar frontal zone within a single austral summer (1976鈥 1977). Collected from icebreakers, research and ...
Habitat suitability forParochlus steineniiunder IPCC RCP4.5 and 8.5 scenarios in the Antarctic. This graph shows the area suitable forP. steineniiin its current distribution (0.6%) in comparison to the area expansion expected under the RCP 4.5 and 8.5 scenarios. ...
In reality, the typical cuspate surface of cold, windblown ice provides excellent friction for tires, to the extent that rubber can be burned off the tire if the wheel locks at high speed. By contrast, snow-free sea ice has a slick surface when temperatures approach the melting point (...
