Sea ice is a composite material made up of pure ice, liquid brine, air, and salt. The volumetric fractions of these components—ice, brine, and air—determine the key physical properties of sea ice, including thermal conductivity, heat capacity, latent heat, density, elastic modulus, and mechanical strength.

30 paź 2024 · The plots and color-coded maps are chosen to provide information about the current state of the sea ice cover and how the most current daily data available compare with the record lows and record highs for the same date during the satellite era.
Measurement of sea ice is important for safety of navigation and for monitoring the environment, particularly the climate. Sea ice extent interacts with large climate patterns such as the North Atlantic oscillation and Atlantic Multidecadal Oscillation, to name just two, and influences climate in the rest of the globe.
Decline in arctic sea ice volume from 1979 to 2022. Sea ice in the Arctic region has declined in recent decades in area and volume due to climate change. It has been melting more in summer than it refreezes in winter. Global warming, caused by greenhouse gas forcing is responsible for the decline in Arctic sea ice.
3 dni temu · Analyze monthly-averaged or daily sea ice extent and concentration via interactive maps. Plot monthly ice extent anomalies, map sea ice concentration anomalies, and more.
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.
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.
