The NASA NSIDC DAAC ICESat/GLAS collection has data products derived from the Geoscience Laser Altimeter System (GLAS) instrument, from 2003 to early 2010. Parameters include sea ice, glacier, and ice sheet elevation, ice roughness, and more. https://nsidc.org/data/icesat

The Extreme Ice Survey Glacier Image Archive at NSIDC holds 1.5 million images from time-lapse cameras (2007-2022), capturing rapid changes in arctic and alpine landscapes. This collection provides crucial data on the speed and extent of glacial retreat. https://bit.ly/4y2mx3g

Display browse images from five different NOAA@NSIDC Arctic sea ice products in a spreadsheet-like format. The tool allows you to quickly compare different time periods and regions in a tabular view. Check it out: https://nsidc.org/data/bist

The Global Land Ice Measurements from Space (GLIMS) Glacier Viewer from the NASA NSIDC DAAC lets you compare glacier outlines from versions 6 and 7 of the Randolph Glacier Inventory. https://bit.ly/4hodZOa

Summer was cool and stormy over the Arctic Ocean. The Arctic sea ice extent average for September was thirteenth lowest in the satellite record. Antarctic sea ice extent dropped sharply through September, hitting record-low daily extents since October 2. https://bit.ly/3TKl3LO

A new study from NSIDC research affiliate Alia Khan shows that penguin poop, a light-absorbing shade of green, melts snow. The penguin poop fertilizes snow algae blooms, and as temperatures rise, snow-algae habitats spread, darkening the snow surface. https://bit.ly/4hHrIhS

The NASA NSIDC DAAC has released the ICESat-2 Cal/Val 2022 L2 CHIR Green Wavelength Lidar Arctic Sea Ice Heights and Bathymetry data set. It has Arctic summer sea ice heights and bathymetry, and aims to evaluate positional accuracies of ATLAS measurements. https://doi.org/10.5067/1HQSJWJGKWDL

Millions of people rely on water from melted snow. NASA's Advanced Microwave Scanning Radiometer for EOS (AMSR-E)/AMSR2 Unified L3 Global Monthly 25 km EASE-Grid Snow Water Equivalent from the NSIDC DAAC provides monthly estimates of snow water content. https://doi.org/10.5067/43NH9LHM9YRK

William O. Field photographed Alaska's Columbia Glacier’s front on Sept 11, 1931. Since 1980, the glacier retreated more than 20 km (12 miles), losing more than half its pre-1980 volume. See thousands of images from NOAA@NSIDC’s Glacier Photo Collection. https://bit.ly/3NcHZxk

As sea levels rise and global topography changes, coastal communities may increasingly need to plan for relocation. But Alaska’s threatened communities have demonstrated the challenge of relocation. https://nsidc.org/news-analyses/news-stories/see-or-not-see-reality-sea-level-rise

Use the NOAA@NSIDC Multisensor Analyzed Sea Ice Extent-Northern Hemisphere (MASIE-NH) data product to select and view an Arctic region's recent ice extent. Compare this year's extent over the last four weeks with the previous four years for the same time: https://bit.ly/4aqImiP

Arctic sea ice extent has reached its minimum for the year, landing at 10th lowest with 2008, 2010, and 2025. Antarctic sea ice may have topped out at 3rd lowest maximum in the satellite record. A full analysis will come out in early Oct from Sea Ice Today:https://bit.ly/4yYW1YB

On Sept 12, Arctic sea ice reached its annual minimum extent of 4.60 million square kilometers (1.78 million square miles), tying for tenth lowest with 2008, 2010, and 2025. The last 20 years are the lowest 20 sea ice extents in the satellite record. https://bit.ly/4Ate4Yl

This year, NSIDC celebrates 50 years of data, research, and service. In 1976, the United States celebrated its bicentennial, disco topped the charts, and no one had yet seen a Star Wars movie. That same year, the NSIDC opened its doors. https://nsidc.org/news-analyses/news-stories/nsidc-turns-50

Nilas is a thin sheet of smooth, level ice less than 10 centimeters (4 inches) thick. It is the first stage in sea ice growth, forming in calm, cold conditions with a dark, almost translucent appearance. Learn more cool terms: NSIDC cryosphere glossary https://bit.ly/4yJOv3z

NOAA@NSIDC is a collaborative program between the National Oceanic and Atmospheric Administration and the National Snow and Ice Data Center that provides free, open-access data on Earth's frozen regions. https://nsidc.org/data/data-programs/noaa-nsidc

The complete multichannel passive microwave record includes sea ice observations from late Oct 1978 to today using the NASA NSIDC DAAC Scanning Multichannel Microwave Radiometer (SMMR), SSM/I, SSMIS, and Advanced Microwave Scanning Radiometer (AMSR2). https://nsidc.org/data/smmr_ssmi
