Data Announcements

The International Ice Patrol (IIP) Iceberg Sightings Database now contains 2010 and 2011 data. The IIP collects information on iceberg activity in the North Atlantic primarily through airborne Coast Guard reconnaissance missions. The data set begins in 1960 and now goes through 2011. NSIDC archives these data for the IIP. To access the data and learn more about it, see the NSIDC International Ice Patrol (IIP) Iceberg Sightings Database Web page.

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 2003 to 2009 by NASA's Ice, Cloud, and Land Elevation Satellite (ICESat) mission.

NASA IceBridge ATM L1B Qfit Elevation and Return Strength data for 2012 Greenland are now available from NSIDC. See the IceBridge ATM L1B Qfit Elevation and Return Strength Web page at https://nsidc.org/data/ilatm1b for more information.

NASA IceBridge DMS L0 Raw Imagery for 2012 Greenland are now available from NSIDC. See the IceBridge DMS L0 Raw Imagery Web page at https://nsidc.org/data/iodms0 for more information.

While the content remains the same, the Sea Ice Index Web site has been functionally redesigned so that it is easier to find and compare earlier years of Sea Ice Index data or check up on trends and anomalies in sea ice extent. This improvement goes hand in hand with edits to the product documentation made in July. Together, these changes make it easier to understand the information the data holds, as well as to simply find and use Sea Ice Index products.

NOAA@NSIDC has archived and made SCICEX 2000 and 2003 Expendable Conductivity, Temperature, and Depth (XCTD) data available from the SCICEX Web site. The data come from an ambitious program to utilize nuclear submarines as a platform to acquire data about the Arctic ocean. XCTD data is but one small portion of the data that has been collected during the SCICEX project. See the SCICEX Data Inventory and Locations Web page to find the 2000 and 2003 XCTD data along with other SCICEX data.

NASA Pre-IceBridge ATM L1B Qfit Elevation and Return Strength data for 1993 to 2008 are now available from NSIDC. See the Pre-IceBridge ATM L1B Qfit Elevation and Return Strength Web page at https://nsidc.org/data/blatm1b for more information.

IceBridge UAF Lidar Scanner L1B Geolocated Surface Elevation Triplets data for Alaska 2011 and 2012, plus reprocessed 2009 and 2010 data, are now available at NSIDC. See the IceBridge UAF Lidar Scanner L1B Geolocated Surface Elevation Triplets Web page at https://nsidc.org/data/ilaks1b for more information.

The Japan Aerospace Exploration Agency (JAXA) has completed reprocessing of the AMSR-E/Aqua L1A Raw Observation Counts data set to Version 3. These Version 3 data are now available from the beginning of the AMSR-E mission through 04 October 2011, when the AMSR-E sensor stopped operating. The new version includes improved geometric accuracy and a switch to a new HDF version, from 4.2r1 to 4.2r4.

The National Snow and Ice Data Center (NSIDC) had humble beginnings when the U.S. World Data Center (WDC) for Glaciology moved to Boulder, Colorado in 1976. A National Research Council recommendation and an agreement between NOAA@NSIDC and the University of Colorado resulted in the NSIDC designation in 1982. Thanks to a Preserve America Initiative Grant (PAIG), this history has been organized, digitized, and made accessible to the public.
