Antarctica is one of the most vulnerable regions to climate change on Earth and studying the
past and present responses of this polar marine ecosystem to environmental change is a …

Diatoms of the iron-replete continental margins and North Atlantic are key exporters of
organic carbon. In contrast, diatoms of the iron-limited Antarctic Circumpolar Current …

Publisher Summary Diatoms are unicellular organisms in which the cell is encapsulated in
an amorphous silica box, called the frustule, composed of two intricate valves. The frustule is …

Abstract The Southern Ocean plays a major role in the glacial/interglacial global carbon
cycle. However, there is a substantial lack of information from its Antarctic Zone south of the …

This review examines the links between pelagic ecology and ocean biogeochemistry with
an emphasis on the role of the Southern Ocean in global cycling of carbon and silica. The …

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 …

Modern analog technique (MAT) applied to Antarctic diatoms is a new approach for
quantitative sea‐ice paleoreconstructions in the Southern Ocean. In a first step we show that …

Premise Understanding the adaptive capacities of species over long timescales lies in
examining the revived recent and millennia‐old resting spores buried in sediments. We …

The sources and sinks of atmospheric carbon dioxide over glacial/interglacial cycles are
under debate. Variation in productivity of the Antarctic Circumpolar Current (ACC) could …

The West Antarctic ice sheet is particularly sensitive to global warming and its evolution and
impact on global climate over the next few decades remains difficult to predict. In this …
