Productivity of Microalgae in Antarctic Sea Ice

Science, 1965
Midsummer productivity of Antarctic microalgae, commonly occurring in brown sea ice along the west coast of the Palmer Peninsula, averaged more than 900 milligrams of carbon per cubic meter per hour, with an assimilation number of about 2.6. The rate of photosynthesis increased with light intensity to a maximum of about 18,000 lux, above which some ...

Biogeochemistry of Antarctic Sea Ice

2002
Antarctic sea ice at its maximum extent in winter covers 40% of the Southern Ocean in a frozen layer, on average, 1 m thick. Sea ice is not solid, rather it is an ice crystal matrix permeated by a labyrinth of brine filled channels and pores in which life thrives.

Whither Antarctic Sea Ice?

Science, 2003
The extent of sea ice around Antartica and the Arctic should be a sensitive indicator of climatic change at the poles. In his Perspective, Wolff highlights the report of Curran et al ., who have compared a potential chemical proxy for sea ice extent from an ice core with satellite records for sea ice extent in the nearby ocean.

Microplastic contamination in east Antarctic sea ice

Marine Pollution Bulletin, 2020
The durability of plastics in the marine environment has led to concerns regarding the pervasiveness of this debris in remote polar habitats. Microplastic (MP) enrichment in East Antarctic sea ice was measured in one ice core sampled from coastal land-fast sea ice.

Microbial mercury methylation in Antarctic sea ice

Nature Microbiology, 2016
Atmospheric deposition of mercury onto sea ice and circumpolar sea water provides mercury for microbial methylation, and contributes to the bioaccumulation of the potent neurotoxin methylmercury in the marine food web. Little is known about the abiotic and biotic controls on microbial mercury methylation in polar marine systems.

Seasonal Change of Antarctic Sea Ice Cover

Science, 1975
The winter expansion of the sea ice surrounding Antarctica and the subsequent retreat of the ice in summer may be linked with the wind stress acting on the Southern Ocean in conjunction with the heat exchange in open water regions within the ice fields.

The Antarctic Sea Ice Cover

1994
The sea ice cover in the Antarctic is one of the most climatically important features of the Southern Hemisphere. Its seasonal variation in extent is from 4 million km2 in summer (February) to 20 million km2 in winter (September) (Zwally et al. 1983).

Antarctic Sea Ice: 1972-1975

Geographical Review, 1979
rT HE areal extent and variability of sea ice is one of the most important of the numerous components that interact to produce global climatic patterns, even for areas far removed from the polar zones. Sea ice in the south-polar region exhibits significant seasonal and interannual variations that from a practical viewpoint are important for Antarctic ...
