Sea Ice in a sentence

Antarctic sea ice cycles seasonally, in February–March the amount of sea ice is lowest, and in August–September the sea ice is at its greatest extent.

The majority of Earth's polar regions are covered in ice, including the Antarctic ice sheet and the sea ice of the Arctic ice pack.

The National Weather Service sea ice forecast shows lots of shore fast ice in the southern Norton Sound, with sea ice thickness increasing along the coast from Nome to Unalakleet.

The Pacific Arctic region, including the Chukchi Sea, was previously known to have experienced a significant reduction of summer sea ice and this new study has demonstrated one mechanism of how sea ice formation can be delayed.

In addition to declining ice extent, the sea ice that remains tends to be younger and thinner than ice that used to cover the region.

Arctic winter temperatures average between -40 to +32° Fahrenheit so the pumped water would create a thick layer of solid ice that would be equivalent to old sea ice that has recently been replaced with thin, less solid ice.

Over the water, ice shelves are shown around Antarctica along with sea ice surrounding the ice shelves.

As of May 7th, satellite imagery of sea ice in the Bering Sea still showed some shore-fast ice clinging to Shishmaref, Wales, and Nome, but none near Unalakleet.

Despite its vulnerability to sea ice change, the narwhal has some flexibility when it comes to sea ice and habitat selection.

Sites surrounding Greenland experience advection (moving) of sea ice from surrounding regions by wind and currents, increasing the variability of sea ice concentration.

In the Siberian sector in particular, average residence time of sea ice floes declined from 15 months to six months after 2007, indicating that most of them were no longer surviving the annual summer melt period to become thick multiyear ice.

Scientists had known before that sea ice was shrinking in extent and getting thinner, but this “flushing” is key, said Mark Serreze, director of the National Snow and Ice Data Center, who wasn’t part of the study.

Sea ice and the Greenland ice sheet are rapidly melting.

Traditionally, teams go across the sea ice on Norton Sound and Golovin Bay, but winter storms have pushed some of that ice out.

It is known that more warming has delayed ice formation, and resulted in thinner sea ice growth.

Melting sea ice levels also attract new economic interest in the region, bringing hope that receding ice will enable access to previously unexploitable energy resources and shipping routes.

By drifting with the ice, the expedition should be able to obtain data throughout the annual cycle of sea ice growth and melt.

In addition, Arctic ice floes are often carried from the Central Arctic to the south (i.e., Fram Strait) by the Transpolar Drift once the sea ice breaks up in spring ().

Scientists have reviewed decades of satellite measurements to reveal how and why Antarctica's glaciers, ice shelves and sea ice are changing.

The active tipping points include the loss of Arctic sea ice and ice sheets in Greenland and Antarctica, the thawing of permafrost and the destruction of boreal forest and the Amazon rainforest.
