Satellite Arctic Ice This website is funded by nasa and managed by nsidc that provides the latest satellite data and scientific analyses of sea ice conditions in the arctic and around antarctica. Polar view delivers information about sea ice and icebergs direct to ships operating in the arctic region. we use several types of satellite imagery to deliver a comprehensive, detailed and up to date picture of sea ice extent and distribution.
Satellite Arctic Ice Up to date satellite observations of the sea ice covers of both the arctic and the antarctic, along with comparisons with the historical satellite record of more than 4 decades. Noaa satellites observe the arctic ocean and atmosphere to understand and forecast arctic change. Visualize arctic and antarctic sea ice extent changes monthly with this interactive arcgis tool. Welcome to the nersc arctic sea ice observation system. nersc has processed daily passive microwave remote sensing data of sea ice from the arctic since they first became available in 1978 using the nersc developed norsex algorithm.

Welcome to the nersc arctic sea ice observation system. nersc has processed daily passive microwave remote sensing data of sea ice from the arctic since they first became available in 1978 using the nersc developed norsex algorithm. Time evolving accumulation of arctic sea ice extent anomalies beginning each season on september 15th and ending in one year. data are shown for seasons of 1979 1980 to 2025 2026 (satellite era; nsidc, dmsp ssm i ssmis and jaxa amsr2). anomalies are calculated using a 5 day running mean from a climatological baseline of 1981 2010. The arctic sea ice today is far younger than in the 1980s and 1990s and is even substantially younger than 2005, with 47% less multi year ice. there is almost no old (>4 years) multi year ice remaining in the arctic, just 95,000 km 2 at the september 2025 minimum. Danish students launched disco 2 satellite to map melting arctic ice in 3d, part of denmark's billion kroner space push. seventy students across three universities built it over years—now it orbits earth. There now exists two decades of basin wide coverage of arctic sea ice from three dedicated polar orbiting altimetry missions (icesat, cryosat 2, and icesat 2) launched by nasa and esa.
