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.
26 lis 2024 · Color-coded map of the daily sea ice concentration in the Southern 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.
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.
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).
Ice, which covers 10 percent of Earth's surface, is disappearing rapidly. Select a topic below to see how climate change has affected glaciers, sea ice, and continental ice sheets worldwide.
Measuring sea-ice thickness is crucial for understanding the state and dynamics of the Arctic and Antarctic regions. It provides essential information for: The picture displays the thickness of sea ice ranging from 0 to 5 metres. March exhibits the highest sea-ice thickness, whereas August demonstrates the lowest level.
