As the frozen parts of our planet face rapid and unprecedented change, NSIDC has been sharing how and why its key features are changing.

This data set compares global atmospheric concentration of methane from ice cores taken on the ice sheets of Antarctica and Greenland. The data come from multiple ice cores on each continent, ...

The Global Terrestrial Network for Permafrost (GTN-P) was established in 1999 by the International Permafrost Association to provide long-term field observations of active layer and permafrost thermal ...

This data set includes chemistry, ion, and istotope data from Taylor Dome, part of the East Antarctic ice sheet. Deep drilling at Taylor Dome successfully reached bedrock at a depth of 554 meters ...

Arctic daily sea ice extent continued to hover near record daily lows in January, with the ice edge well northward of its long-term average position in most areas. In contrast to the cold conditions ...
