The Roger G. Barry Archives and Resource Center (ARC), formerly ROCS, at NSIDC maintains a unique and rare collection, documenting early polar exploration and the first scientific expeditions to the far reaches of our planet. These collections provide researchers priceless historical insight into how the Earth's polar and icy regions have changed. As a soft money funded organization with no endowment, our facility is under threat. Traditional funding sources no longer support the collection.
The NASA IceBridge CAMBOT L1B Geolocated Images for 2012 Arctic are now available from NSIDC. See the IceBridge CAMBOT L1B Geolocated Images Web page at https://nsidc.org/data/iocam1b for more information.
NASA IceBridge Sander AIRGrav L1B Geolocated Free Air Gravity Anomalies data for Arctic 2012, and replacement Arctic 2010 and 2011 data are now available at NSIDC. See the IceBridge Sander AIRGrav L1B Geolocated Free Air Gravity Anomalies Web page at https://nsidc.org/data/iggrv1b for more information.
NASA IceBridge Scintrex CS-3 Cesium Magnetometer L1B Geolocated Magnetic Anomalies data for Arctic 2012 are now available from NSIDC. See the IceBridge Scintrex CS-3 Cesium Magnetometer L1B Geolocated Magnetic Anomalies Web page at https://nsidc.org/data/imcs31b for more information.
This data set characterizes the microstructure in ice cores, in particular the microstructural locations of impurities, grain orientations, and strain gradients. The fabric of polycrystalline ice is typically described using only the c-axis orientation, but this is insufficient for a full description of grain orientations in this hexagonal material.
NASA IceBridge LVIS L1B Geolocated Return Energy Waveforms data for 2012 Arctic and replacement data for 2011 Antarctica are now available from NSIDC. See the IceBridge LVIS L1B Geolocated Return Energy Waveforms Web page at https://nsidc.org/data/ilvis1b for more information.
NASA IceBridge LVIS L2 Geolocated Surface Elevation Product 2012 Arctic data are now available from NSIDC. See the IceBridge LVIS L2 Geolocated Surface Elevation Product Web page at https://nsidc.org/data/ilvis2 for more information.
On 16 November 2012, the MCoRDS L1B Geolocated Radar Echo Strength Profiles 2012 Arctic data, previously referred to as 2012 Greenland, were replaced. See the IceBridge MCoRDS L1B Geolocated Radar Echo Strength Profiles page for more information.
NSIDC has been notified of an error in AMSR-E sea ice data products that caused valid data in the Southern Hemisphere to be obscured by a land mask. The products and algorithms affected by this error are:
NASA IceBridge Sea Ice Freeboard, Snow Depth, and Thickness data for 2011 Greenland are now available from NSIDC. See the IceBridge Sea Ice Freeboard, Snow Depth, and Thickness Web page at https://nsidc.org/data/idcsi2 for more information.
From 1893 to 1956, the Danish Meteorological Institute (DMI) created charts of observed and inferred sea ice extent for each summer month. These charts are based on compiled observations of ice conditions from Arctic expeditions and shore observers. The charts were scanned at the Icelandic Meteorological Office (IMO) and are being made available by NOAA@NSIDC as a service and in cooperation with DMI and other contributors.
NASA IceBridge MCoRDS L2 Ice Thickness data for 2012 Greenland are now available from NSIDC. See the IceBridge MCoRDS L2 Ice Thickness Web page at https://nsidc.org/data/irmcr2 for more information.
The User Services Office at NSIDC is available Monday through Friday from 9 a.m. to 5 p.m. USA Mountain Time to help with any IceBridge data questions. If you are experiencing difficulty accessing IceBridge data via the FTP or the IceBridge Data Portal, or if you need help regarding file formats, data resolution, or other documentation matters, we are here to help. We strive to respond to inquiries within one business day, so please do not hesitate to write us at nsidc@nsidc.org or call 303-492-6199.
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.
Landfast sea ice is sea ice that is anchored to the shore or ocean bottom, typically over shallow ocean shelves at continental margins; it is defined by the fact that it does not move with the winds or currents. This data set, Landfast Ice 1953-1998, contains monthly mean concentrations of fast ice for the Arctic Ocean from both the Arctic and Antarctic Research Institute (AARI) and the Canadian Ice Services (CIS) sources. To access the data and learn more about it, see the Arctic Landfast Sea Ice 1953-1998 Web page.
NASA IceBridge LVIS POS/AV L1B Corrected Position and Attitude Data for 2011 Antarctica, 2011 Greenland, and 2012 Greenland are now available from NSIDC. See the IceBridge LVIS POS/AV L1B Corrected Position and Attitude Data Web page at https://nsidc.org/data/ipplv1b for more information.
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 L2 Icessn Elevation, Slope, and Roughness data for 2012 Greenland are now available from NSIDC. See the IceBridge ATM L2 Icessn Elevation, Slope, and Roughness Web page at https://nsidc.org/data/ilatm2 for more information.
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.
