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.

NASA IceBridge DMS L1B Geolocated and Orthorectified Images for 2012 Greenland are now available from NSIDC. See the IceBridge DMS L1B Geolocated and Orthorectified Images Web page at https://nsidc.org/data/iodms1b for more information.

The updated IceBridge data portal now includes Antarctica and Greenland. Explore the portal at https://nsidc.org/icebridge/portal/.

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.

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.

NASA IceBridge Sigma Space Photon Counting Lidar L2 Geolocated Nadir Photon Elevations data for 2011 Antarctica are now available from NSIDC. See the IceBridge Sigma Space Photon Counting Lidar L2 Geolocated Nadir Photon Elevations Web page at https://nsidc.org/data/ilsnp2 for more information.

NASA IceBridge KT19 IR Surface Temperature data for 2012 Arctic sea ice and land ice are now available from NSIDC. See the IceBridge KT19 IR Surface Temperature Web page at https://nsidc.org/data/iakst1b for more information.

NASA IceBridge MCoRDS L1B Geolocated Radar Echo Strength Profiles data for 2012 Greenland are now available from NSIDC. See the IceBridge MCoRDS L1B Geolocated Radar Echo Strength Profiles Web page at https://nsidc.org/data/irmcr1b for more information.

NOAA@NSIDC has acquired DOI numbers for two of our most popular data sets: the World Glacier Inventory and theGlacier Photograph Collection. This is in an effort to make our data easier to find and access in the digital environment and to provide persistent identification. The team plans to acquire DOI numbers for more data sets as time and funding allow.
