Grease ice makes the water resemble an oil slick, the small crystals of ice held closely together reflect and refract light similarly to how oil will on water. Photo by Nina Munteanu. Find more terms of Earth's frozen region in NSIDC's glossary: nsidc.org/learn/cryosphere-g…

Scientific data should be FAIR: Findable, Accessible, Interoperable, and Reproducible. Openscapes helps with that. Be inspired to collaborate on your research! bit.ly/4erHL2V

The Advanced Microwave Scanning Radiometer-Earth Observing System's (AMSR-E's) sensor can pierce clouds. Even in polar darkness it tracks sea ice changes year-round. AMSR-E data are available from the NASA NSIDC Distributed Active Archive Center (DAAC). bit.ly/43jRNgn

The National Oceanic and Atmospheric Administration at NSIDC (NOAA@NSIDC) program is one of the only places in the world that archives long-term records of Earth's frozen regions. See the most popular products: nsidc.org/data/data-programs…

Since 1917, Nenana, Alaska, has hosted a contest to predict when ice on the Tenana River breaks up come spring. A tripod, wired to an onshore clock, is planted during freeze up. The clock stops when the tripod moves. See the data at the NASA NSIDC DAAC: bit.ly/43i7Lrk.

Did you know that the NOAA Multisensor Analyzed Sea Ice Extent-Northern Hemisphere (MASIE-NH) offers daily images and times series plots for individual Arctic regions? Such as Baffin Bay, which has hit a record low since early May. Check out other regions: bit.ly/4aqImiP

Snow-covered area across the West was 49 percent of average for May, ranking last in the 26-year satellite record. Snow water equivalent remained well below average in most states, confirming a worrisome outlook for the summer. Read NSIDC's Snow Today: bit.ly/3Q20sRs

The Extreme Ice Survey (EIS) images at NSIDC include over 1.5 million glacial photographs from 2007-2022, capturing time-lapse changes in arctic and alpine landscapes. This collection provides crucial data on the speed and extent of glacial retreat. youtube.com/watch?v=5wtlbhjc…

NASA's Advanced Topographic Laser Altimeter System (ATLAS) aboard Ice, Cloud and Elevation Satellite-2 (ICESat-2) employs three pairs of laser beams aimed at Earth’s surface, emitting 10,000 pulses per second, with 300 trillion photons per pulse. bit.ly/4ai0ICD

NOAA's monthly Sea Ice Index shows changes in polar sea ice extent and concentration since 1979. The index also offers monthly images of differences from average in ice concentration: blue values indicate below the 1981-2010 average, red are above average. bit.ly/4rC92nn

Before satellites, scientists stitched together aerial photographs of big features, such as Greenland’s Jakobshavn Glacier. This composite image dates from 1970 and 1971 and is now available in the NSIDC Glacier Photograph Collection. nsidc.org/data/glacier_photo…
