Phytoplankton are the base of the Antarctic food web, sustain the wealth and diversity of life
for which Antarctica is renowned, and play a critical role in biogeochemical cycles that …

Antarctic krill (Euphausia superba) are swarming, oceanic crustaceans, up to two inches
long, and best known as prey for whales and penguins–but they have another important …

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 …

Low levels of iron limit primary productivity across much of the Southern Ocean. At the basin
scale, most dissolved iron is supplied to surface waters from subsurface reservoirs, because …

Observations from the last decade suggest an important role of sea ice in the global
biogeochemical cycles, promoted by (i) active biological and chemical processes within the …

Antarctic coastal polynyas are biologically rich ecosystems that support large populations of
mammals and birds and are globally significant sinks of atmospheric carbon dioxide. To …

We present here the first mercury speciation study in the water column of the Southern
Ocean, using a high-resolution south-to-north section (27 stations from 65.50° S to 44.00° S) …

Dissolved iron (DFe) and total dissolvable Fe (TDFe) were measured in January–February
2009 in Pine Island Bay, as well as in the Pine Island and Amundsen polynyas (Amundsen …

Due to its importance as a limiting nutrient for phytoplankton growth in large regions of the
world's oceans, ocean water column observations of concentration of the trace-metal iron …

The discovery that melting sea ice can fertilize iron (Fe)-depleted polar waters has recently
fostered trace metal research efforts in sea ice. The aim of this review is to summarize and …
