Ice lost, island found?

The eastern coast of Antarctica has lost most of the Glenzer and Conger ice shelves. In the process, it gained what is likely an island. If confirmed, the unnamed island would be one in a series of islands exposed in recent ...

Antarctic sea-ice expansion in a warming climate

Antarctic sea-ice has expanded over the period of continuous satellite monitoring, which seemingly contradicts ongoing global warming resulting from increasing concentrations of greenhouse gasses. In a study, published in ...

Study illustrates nuances of gravitational pull of ice sheets

It is well known that global warming is causing sea levels to rise via two processes: thermal expansion, when water expands because of its increased temperature, and melting of land-based ice, when meltwater flows into the ...

Record low Antarctic sea ice extent could signal shift

Sea ice around Antarctica shrank to the smallest extent on record in February, five years after the previous record low, researchers said Tuesday, suggesting Earth's frozen continent may be less impervious to climate change ...

Sea ice

Sea ice is formed from ocean water that freezes. Because the oceans consist of saltwater, this occurs at about -1.8 °C (28.8 °F).

Sea ice may be contrasted with icebergs, which are chunks of ice shelves or glaciers that calve into the ocean. Icebergs are compacted snow and hence fresh water.

Sea ice may be deliberately created or manipulated, see Arctic geoengineering for details.
