Young ice is a transition stage between nilas and first-year ice and ranges in thickness from 10 cm (3.9 in) to 30 cm (12 in), Young ice can be further subdivided into grey ice – 10 cm (3.9 in) to 15 cm (5.9 in) in thickness and grey-white ice – 15 cm (5.9 in) to 30 cm (12 in) in thickness. Young ice is not as flexible as nilas, but tends ...
The Caspian Sea is either the world's largest lake or a full-fledged inland sea [note 1] Round Tangle Lake, one of the Tangle Lakes, 2,864 feet (873 m) above sea level in interior Alaska. The largest lake by surface area is Caspian Sea, which is despite its name considered as a lake from the point of view of geography. [79]
Eustatic sea level change (global as opposed to local change) is due to change in either the volume of water in the world's oceans or the volume of the oceanic basins. [14] Two major mechanisms are currently causing eustatic sea level rise. First, shrinking land ice, such as mountain glaciers and polar ice sheets, is releasing water into the ...
Fast ice (also called land-fast ice, landfast ice, and shore-fast ice) is sea ice or lake ice [1] that is "fastened" to the coastline, to the sea floor along shoals, or to grounded icebergs. [ 2 ] [ 3 ] [ 4 ] Fast ice may either grow in place from the sea water or by freezing pieces of drifting ice to the shore or other anchor sites.
Antarctica’s vast expanse of sea ice regulates Earth’s temperature, as the white surface reflects the Sun’s heat back into the atmosphere. Record low sea-ice levels around Antarctica ...
As the temperature continues to drop, the water on the surface may get cold enough to freeze and the lake/ocean begins to ice over. A new thermocline develops where the densest water (4 °C (39 °F)) sinks to the bottom, and the less dense water (water that is approaching the freezing point) rises to the top.
NASA uses that power to provide data on sea ice levels via the National Snow and Ice Data Center, which records the seasonal changes in the amount of sea ice and plots trends over time. Now, in ...
The claim: Polar sea ice extents show climate change is a 'scam' A Dec. 23, 2024, Facebook post (direct link, archive link) shows a map of Antarctic sea ice extent, or area, with color coding that ...
