Data Announcements

Ice core chemistry from the Norwegian-U.S. Scientific Traverse of East Antarctica, IPY 2007-2009 is now available from The Antarctic Glaciological Data Center (AGDC) at NSIDC. Data and documentation may be accessed through the catalog page.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 International Polar Year (IPY) 2007-2009.

NOAA@NSIDC is pleased to announce that the Sea Ice Index data archive now has daily as well as monthly ice extent numbers for the northern and southern hemispheres. The product documentation has also been overhauled to include an explanation of how these are made and to give a clearer and complete description of all Sea Ice Index products. The documentation now includes the following: Flow charts to make data processing steps easier to follow. Explanation on how the median edge position is determined and why it is used.
