2 dni temu · 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. Sea Ice Today began as a way to make sea ice science and analysis more relevant and accessible.

30 paź 2024 · The most recent sea ice concentration data (for the current year) shown in Figures 1, 3, 5, and 7 are produced at NASA Goddard Space Flight Center with near-real-time brightness temperatures (Meier et al., 2022 3).
The figure shows the latest 36-hour sliding mean temperature of the ice- and ocean surface. The Danish arctic research institutions present updated knowledge on the condition of two major components of the Arctic: The Greenland Ice Sheet and the sea ice.
Animations and daily updates of satellite products from the Arctic sea ice. See maps of sea ice extent and thickness, comparisons of ice cover and volume with previous years, the evolution of sea ice temperatures and the distribution of icebergs.
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.
The daily Sea Ice Index provides a quick look at Antarctic-wide changes in sea ice. It provides consistently processed daily ice extent and concentration images and data since 1979. Daily extent images show ice extent at concentrations greater than 15% for a given day with an outline of the typical extent for that day based on a 30-year (1981 ...
Sea Ice Forecasts. 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. The model is initialized with the NOAA Global Forecast System (GFS) analyses and the Advanced Microwave Scanning ...
