Mar 12, 2025 · Color-coded map of the daily sea ice concentration in the Northern Hemisphere for the indicated recent date along with the contours of the 15% edge during the years with the least extent of ice (in red) and the greatest extent of ice (in orange) during the period from November 1978 to the present.

Sea ice map calculated from AMSR2 data using the ARTIST sea ice algorithm (ASI 5).

Visualize sea ice extent (area of ocean with at least 15 percent sea ice concentration) data for the Arctic and Antarctic. View and compare sea ice extent data for any year or any combination of years from 1979 to present (including near-real-time daily data).

During the winter, on average about 18.5 million square kilometers (7.1 million square miles) of ocean is covered by sea ice, but by the end of summer, only about 2.5 million square kilometers (965,000 square miles) of sea ice remain.

Stunning satellite imagery of Alaska's coast, snow and ice cover, and more. Interactive timeline slider lets you see past images, and pan/zoom the image for more detail. See Alaska from space!

Explore predictions that global climate models make about future changes in sea ice extent. Go to the NSIDC web site to: View multiple maps of various ice measurements at the same time. View an interactive sea ice extent graph to examine ice extent by …

In this part of, you can view maps of the sea-ice concentration in the Arctic and Antarctic and select the timeframe you’re most interested in. You can also download the graphics you’ve selected and, with proper citation, use them elsewhere.

The map of the ice thickness shows the mean thickness of ice in each grid cell. The graph on the right shows the annual variation of the volume of the sea ice in the Northern Hemisphere, excluding the Baltic Sea and the Pacific.
