These 0-10 day, experimental, sea ice forecasts are produced by the NOAA Physical Sciences Laboratory from a fully coupled ice-ocean-atmosphere model called CAFS. CAFS is run daily and posted online at 2 UTC.

This map shows sea ice concentration across the Arctic Ocean and surrounding seas. Concentration is color coded, with high concentrations appearing in white or very light blue, and low concentrations appearing in darker blue.

NOAA Climate.gov graph, based on extent data from the National Snow and Ice Data Center. Since the start of the satellite era in 1979, the extent of ice covering the Arctic Ocean at the end of summer has shrunk by more than 40 percent.

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.

The Arctic Ocean is the smallest and shallowest of the world's five oceanic divisions. [1] It spans an area of approximately 14,060,000 km 2 (5,430,000 sq mi) and is the coldest of the world's oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea. [2] It has also been described as …
