A strong mid-Holocene transition has been identified by wavelet analyses in several sea ice
cover records from the circum-Antarctic area, ice core records (Taylor dome, Byrd) and …

Dramatic changes in sea ice have been observed in both poles in recent decades. However,
the observational period for sea ice is short, and the climate models tasked with predicting …

The isolation of the Southern Ocean after the opening of Drake Passage some 23–25 million
years ago, the formation of the Antarctic Circumpolar Current, the subsequent cooling of the …

The influence of Antarctica and the Southern Ocean on Late Pliocene global climate
reconstructions has remained ambiguous due to a lack of well-dated Antarctic-proximal …

Knowing the patterns of distribution of sediments in the global ocean is critical for
understanding biogeochemical cycles and how deep-sea deposits respond to …

Diatoms from 228 Southern Ocean core-top sediment samples were examined to determine
the geographic distributions of 32 major diatom species/taxa preserved in the sediments of …

The potential interactive effects of iron (Fe) limitation and Ocean Acidification in the Southern
Ocean (SO) are largely unknown. Here we present results of a long-term incubation …

Fractionation of silicon (Si) isotopes was measured in seven species (nine strains) of polar
and sub-polar marine diatoms grown in semi-continuous unialgal cultures under optimal …

The causes of the recent increase in Antarctic sea ice extent, characterised by large regional
contrasts and decadal variations, remain unclear. In the Ross Sea, where such a sea ice …

The role of algae for sequestration of atmospheric mercury in the ocean is largely unknown
owing to a lack of marine sediment data. We used high-resolution cores from marine …
