BIOGEOCHEMISTRY OF ANTARCTIC SEA ICE
2002Antarctic 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.

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, 2020The 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.

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 ...

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.
