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.

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.
