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 Metadata Directory (AMD) to comply with the Antarctic Treaty and represent the U.S. in Scientific Committee on Antarctic Research (SCAR) activities.
