Southern Ocean carbon-wind stress feedback
The Southern Ocean is the largest sink of anthropogenic carbon in the present-day climate. Here, Southern Ocean pCO 2 pCO2 and its dependence on wind forcing are investigated using an […]

Importation of psychrotolerant fungi to Antarctic associated with wooden cargo packaging
Read more of: Importation of psychrotolerant fungi to Antarctic associated with wooden cargo packagingThe harsh climatic conditions and low levels of human activity in Antarctica, relative to other regions, means few non-native species have established. However, the risk of introductions is becoming greater […]

A long-term study of gentoo penguin (Pygoscelis papua) population trends at a major Antarctic tourist site, Goudier Island, Port Lockroy
Read more of: A long-term study of gentoo penguin (Pygoscelis papua) population trends at a major Antarctic tourist site, Goudier Island, Port LockroyGentoo penguins Pygoscelis papua breed at a number of sites at the West Antarctic Peninsula, including Goudier Island, Port Lockroy—the longest studied location for tourist-penguin interactions in the Antarctic. These […]

How will vessels be inspected to meet emerging biofouling regulations for the prevention of marine invasions?
Read more of: How will vessels be inspected to meet emerging biofouling regulations for the prevention of marine invasions?International and national guidelines and regulations to limit the inadvertent transfer of non-native species on the submerged surfaces of vessels and mobile infrastructure are progressing. However, methods to assess compliance […]

Life cycle and phenology of an Antarctic invader – the flightless chironomid midge, Eretmoptera murphyi
Read more of: Life cycle and phenology of an Antarctic invader – the flightless chironomid midge, Eretmoptera murphyiKnowledge of the life cycles of non-native species in Antarctica is key to understanding their ability to establish and spread to new regions. Through laboratory studies and field observations on […]

Using habitat models to identify marine important bird and biodiversity areas for Chinstrap Penguins Pygoscelis antarcticus in the South Orkney Islands
Read more of: Using habitat models to identify marine important bird and biodiversity areas for Chinstrap Penguins Pygoscelis antarcticus in the South Orkney IslandsTracking individual marine predators can provide vital information to aid the identification of important activity (foraging, commuting, rafting, resting, etc.) hotspots and therefore also to delineate priority sites for conservation. […]

Protective mechanisms and responses of micro-fungi towards ultraviolet-induced cellular damage
Read more of: Protective mechanisms and responses of micro-fungi towards ultraviolet-induced cellular damageFungi are microbes that play vital roles in nutrient cycling in natural environments and in symbiotic interactions with plants and other microbes. They thrive successfully even when challenged by various […]

Surface meltwater impounded by seasonal englacial storage in West Greenland
Read more of: Surface meltwater impounded by seasonal englacial storage in West GreenlandThe delivery of surface meltwater through englacial drainage systems to the bed of the Greenland Ice Sheet modulates ice flow through basal lubrication. Recent studies in Southeast Greenland have identified […]

Seasonal variation in the predatory impact of myctophids on zooplankton in the Scotia Sea (Southern Ocean)
Read more of: Seasonal variation in the predatory impact of myctophids on zooplankton in the Scotia Sea (Southern Ocean)Myctophids are the biomass-dominant mesopelagic fishes in the Southern Ocean, but their trophic role within the pelagic food web south of the Antarctic Polar Front is poorly resolved from a […]
