A 30-year simulation of the outer electron radiation belt
Read more of: A 30-year simulation of the outer electron radiation beltAs society becomes more reliant on satellite technology, it is becoming increasingly important to understand the radiation environment throughout the Van Allen radiation belts. Historically most satellites have operated in […]

Vertical Structure of Diurnal Englacial Hydrology Cycle at Helheim Glacier, East Greenland
Read more of: Vertical Structure of Diurnal Englacial Hydrology Cycle at Helheim Glacier, East GreenlandThe interior dynamics of Helheim Glacier were monitored using an autonomous phase‐sensitive radio‐echo sounder (ApRES) during two consecutive summers. The return signals from all observational sites exhibited strong non‐tidal, depth‐dependent […]

Salinity control of thermal evolution of late summer melt ponds on Arctic sea ice
Read more of: Salinity control of thermal evolution of late summer melt ponds on Arctic sea iceThe thermal evolution of melt ponds on Arctic sea ice was investigated through a combination of autonomous observations and two‐dimensional high‐resolution fluid dynamics simulations. We observed one relatively fresh pond […]

Precipitation instruments at Rothera Station, Antarctic Peninsula: a comparative study
Read more of: Precipitation instruments at Rothera Station, Antarctic Peninsula: a comparative studyDirect measurement of precipitation in the Antarctic using ground-based instruments is important to validate the results from climate models, reanalyses and satellite observations. Quantifying precipitation in Antarctica faces many unique […]

Southern Ocean carbon-wind stress feedback
Read more of: Southern Ocean carbon-wind stress feedbackThe 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 […]
