This data set characterizes the microstructure in ice cores, in particular the microstructural locations of impurities, grain orientations, and strain gradients. The fabric of polycrystalline ice is typically described using… Read more »
This data set contains lake boundaries, volume changes, and gridded elevations for 124 active subglacial lakes beneath the Antarctic ice sheet. Lakes were identified using laser altimetry data obtained from… Read more »
This data set consists of sodium (Na) and magnesium (Mg) concentrations versus depth in seven ice cores that were obtained by the Norwegian-U.S. Scientific Traverse of East Antarctica during the… Read more »
This data set contains light absorption coefficients for soluble chromophores (light-absorbing chemicals) and concentrations of hydrogen peroxide (HOOH) and nitrate (NO3-) in ten snow samples that were collected in 2003… Read more »
This data set provides a coastline history of the eastern Amundsen Sea Embayment and terminus histories of its outlet glaciers derived from those coastlines. These outlet glaciers include Smith, Haynes,… Read more »
The Antarctic Glaciological Data Center (AGDC) at NSIDC has published new data sets. AGDC archives and distribtues data from National Science Foundation Office of Polar Programs-funded researchers.
The Antarctic Glaciological Data Center (AGDC) at NSIDC has published the ASTER GDEM 100-m Digital Elevation Model of the Antarctic Peninsula. The data set provides a 100-meter resolution surface topography Digital Elevation Model (DEM) of the Antarctic Peninsula.
The Antarctic Glaciological Data Center (AGDC) at NSIDC has released new data sets relating to Antarctic firn samples, ice cores, and ice motion.
The Antarctic Glaciological Data Center at NSIDC has released a new data set, containing depth profiles for methane (CH4) in South Pole firn air. The profiles represent a roughly 100-year… Read more »
