Sea Ice Today - National Snow and Ice Data Center
The Arctic is warming faster than anywhere else on the planet, and as a result, sea ice in the Arctic Ocean is decreasing. Sea ice loss has far-reaching effects on the planet because the ice helps regulate Earth’s climate, influences global weather patterns, and affects ocean circulations.
Current State of Sea Ice Cover | Earth - NASA
2024年10月10日 · Shown below are 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.
Sea Ice Index Daily and Monthly Image Viewer
The daily Sea Ice Index provides a quick look at Arctic-wide changes in sea ice. It provides consistently processed daily ice extent and concentration images and data since 1979.
Arctic Sea Ice Near Historic Low; Antarctic Ice Continues Decline
2024年9月24日 · Arctic sea ice retreated to near-historic lows in the Northern Hemisphere this summer, likely melting to its minimum extent for the year on Sept.11, 2024, according to researchers at NASA and the National Snow and Ice Data Center (NSIDC).
Charctic Interactive Sea Ice Graph - National Snow and Ice Data …
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).
Sea Ice - NOAA Arctic
The substantial decline in Arctic ice extent since 1979 is one of the most iconic indicators of climate change. The seasonal cycle of Arctic sea ice is characterized by the maximum annual extent in March, decreasing through spring and summer …
Sea Ice - NOAA Arctic
Arctic sea ice is the frozen interface between the ocean and the atmosphere. It reduces the absorption of solar energy because of its high albedo relative to the darker open ocean surface. In addition, as a physical barrier, it modifies the heat and …
Sea Ice Thickness and Volume - Polar Portal
The ice cover in the Arctic grows throughout the winter, before peaking in March. Melting picks up pace during the spring as the sun gets stronger, and in September the extent of the ice cover is typically only around one third of its winter maximum.
Sea Ice - NOAA Arctic
Sea ice extent, defined as the total area covered by ice of at least 15% concentration, is a common metric to assess seasonal and long-term changes in Arctic sea ice. Starting in 1979, there is now a 44-year record of ice extent derived from a consistent series of satellite-borne passive microwave sensors.
Arctic Sea Ice Forecasts: NOAA Physical Sciences Laboratory
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.
