UTAS01: data collation of the climate-cooling gas dma in antarctic snow, sea ice and UNDERLYING sea water

Dimethyl sulfide (DMS) is a biogenic source of sulfate aerosol that influences the climate system by reducing solar radiation and altering cloud properties. Recent observations suggest that DMS may play a dominant role in the aerosol and cloud formation along the Antarctic coast where DMS is produced by marine microbes that reside on top, in, and under sea ice. However, the role of DMS remains unclear especially over the regional scale, partly due to the lack of compilation of DMS data.

Research brief: Indian Ocean played key role in rapid 2016 Antarctic ice decline

Antarctic sea ice had been growing in area since 1979, despite the influence of global warming. Then unexpectedly in the austral spring of 2016, there was a rapid decline. CLEX researchers used multiple runs of a coupled ocean-atmosphere climate model to investigate whether these distant influences played a role and, if so, the level of the contribution to the sea-ice decline.

Research brief: What caused the rapid decline in Antarctic sea ice in 2016?

Antarctic sea ice extent underwent a rapid decline in the spring of 2016 and is still well below average now. CLEX researchers have tied the decline to natural variability of both the atmosphere and ocean in two articles published in Nature Communications this month.

Research brief: Drivers of Antarctic sea ice volume change in CMIP 5 models

CLEX researchers find that ocean sea-ice models generally agreed on changes to average yearly cycle of freeze and melt in Antarctica, with dynamic processes dominating the sea ice edge and thermodynamic processes dominating the interior of the sea ice pack. However, the models disagreed about the trends of sea ice volume.
