Welcome

The U.S. Antarctic Program Data Center (USAP-DC) supports investigators funded by the National Science Foundation in documenting, preserving, and disseminating their research results. We provide a central USAP Project Catalog for all projects funded by the NSF Antarctic program and a Data Repository for research datasets derived from these projects. Data managed include the NSF research related glaciology data collection formerly managed through NSIDC. We register datasets in the Antarctic Master Directory (AMD) to comply with the Antarctic Treaty and represent the U.S. in Scientific Committee on Antarctic Research (SCAR) activities.

Map shows datasets registered with the USAP-DC. Dots show the locations of the centroid of the geographic bounding box for each data set or the point locations for datasets from single sites (e.g. ice cores). Click on centroid locations to view the full bounding box as provided by the contributing scientists as well as more information about the datasets.
