Productivity of Microalgae in Antarctic Sea Ice
Science, 1965Midsummer 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 ...

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.

Seasonal Change of Antarctic Sea Ice Cover
Science, 1975The 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.

Microbial mercury methylation in Antarctic sea ice
Nature Microbiology, 2016Atmospheric 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.

Following a multidecade increase, Antarctic sea ice declined drastically during austral spring 2016. Suggested causes of the sea ice decline include lingering effects of the 2015/2016 extreme El Niño and a tropical Indian Ocean teleconnection to high ...

Primary Production in Antarctic Sea Ice
Science, 1997A numerical model shows that in Antarctic sea ice, increased flooding in regions with thick snow cover enhances primary production in the infiltration (surface) layer. Productivity in the freeboard (sea level) layer is also determined by sea ice porosity, which varies with temperature. Spatial and temporal variation in snow thickness and the proportion

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 ...

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).
