Overall, Arctic sea ice area has declined for every month since 1979, according to National Snow and Ice Data Center data. Sea ice area on April 29 in both 1989 and 2024 was well below the 1979 ...

In the Arctic, it will measure the elevation of the ice floes, compared to the water level. However, only about one-tenth of sea ice is above the water surface; the other nine-tenths lie below.
