Cyclone-induced rapid creation of extreme Antarctic sea ice conditions
Two polar vessels, Akademik Shokalskiy and Xuelong, were trapped by thick sea ice in the Antarctic coastal region just to the west of 144°E and between 66.5°S and 67°S in […]

Millimeter-Sized Marine Plastics: A New Pelagic Habitat for Microorganisms and Invertebrates
Read more of: Millimeter-Sized Marine Plastics: A New Pelagic Habitat for Microorganisms and InvertebratesMillimeter-sized plastics are abundant in most marine surface waters, and known to carry fouling organisms that potentially play key roles in the fate and ecological impacts of plastic pollution. In […]

Medical memorials of the Heroic Age of Antarctic exploration
Read more of: Medical memorials of the Heroic Age of Antarctic explorationThe Heroic Age of Antarctic exploration spanned the period from 1895 to 1922. Medical men who took part in the expeditions of that period made significant contributions to the expeditions […]

Export and circulation of ice cavity water in Pine Island Bay, West Antarctica
Read more of: Export and circulation of ice cavity water in Pine Island Bay, West AntarcticaLarge sectors of the Antarctic ice sheet are vulnerable to increases in melting at the bases of fringing ice shelves, with melt rates depending on ocean temperatures and circulations in […]

Electromagnetic ion cyclotron wave modeling during the geospace environment modeling challenge event
Read more of: Electromagnetic ion cyclotron wave modeling during the geospace environment modeling challenge eventWe investigate the temporal evolution and the spatial distribution of electromagnetic ion cyclotron (EMIC) waves during the 8–11 June 2001 geomagnetic storm, one of the storms selected for study by […]

Geographic isolation and physiological mechanisms underpinning species distributions at the range limit hotspot of South Georgia
Read more of: Geographic isolation and physiological mechanisms underpinning species distributions at the range limit hotspot of South GeorgiaIn order to allocate quotas for sustainable harvests, that account for climate warming, it is important to incorporate species vulnerabilities that will underlie likely changes in population dynamics. Hotspots, regions […]

Climate-linked iceberg activity massively reduces spatial competition in Antarctic shallow waters
Read more of: Climate-linked iceberg activity massively reduces spatial competition in Antarctic shallow watersLife on Antarctica’s coastal seabed rollercoasters between food-rich, open-water, iceberg-scoured summers and food-sparse winters, when the sea surface freezes into ‘fast-ice’, locking up icebergs, reducing their seabed collisions (scouring). In […]

Mycothalli of the hepatic Barbilophozia hatcheri in Antarctica: distribution and identities of mycobionts
Read more of: Mycothalli of the hepatic Barbilophozia hatcheri in Antarctica: distribution and identities of mycobiontsForty-four herbarium specimens of the hepatic Barbilophozia hatcheri, collected from across the entire range of the species in Antarctica (54–68 °S), were examined for fungal colonisation. Mycothalli, consisting of hyaline […]

Reproductive morphology of the deep-sea protobranch bivalves Yoldiella ecaudata, Yoldiella sabrina, and Yoldiella valettei (Yoldiidae) from the Southern Ocean
Read more of: Reproductive morphology of the deep-sea protobranch bivalves Yoldiella ecaudata, Yoldiella sabrina, and Yoldiella valettei (Yoldiidae) from the Southern OceanThe protobranch bivalves of the Southern Ocean are poorly understood ecologically, despite their high abundances in soft sediments from the shelf to the deep sea. The subclass has a long […]

A reversal of fortunes: climate change ‘winners’ and ‘losers’ in Antarctic Peninsula penguins
Read more of: A reversal of fortunes: climate change ‘winners’ and ‘losers’ in Antarctic Peninsula penguinsClimate change is a major threat to global biodiversity. Antarctic ecosystems are no exception. Investigating past species responses to climatic events can distinguish natural from anthropogenic impacts. Climate change produces […]
