Extreme temperatures in the Antarctic
We present the first Antarctic-wide analysis of extreme near-surface air temperatures based on data collected up to the end of 2019 as part of the synoptic meteorological observing programs. We […]

Coupled impacts of sea ice variability and North Pacific atmospheric circulation on Holocene hydroclimate in Arctic Alaska.
Read more of: Coupled impacts of sea ice variability and North Pacific atmospheric circulation on Holocene hydroclimate in Arctic Alaska.Arctic Alaska lies at a climatological crossroads between the Arctic and North Pacific Oceans. The modern hydroclimate of the region is responding to rapidly diminishing sea ice, driven in part […]

Comparison of interferometer calibration techniques for improved SuperDARN elevation angles
Read more of: Comparison of interferometer calibration techniques for improved SuperDARN elevation anglesThe high frequency radars in the Super Dual Auroral Radar Network (SuperDARN) estimate the elevation angles of returned backscatter using interferometric techniques. These elevation angles allow the ground range to […]

Seasonal evolution of winds, atmospheric tides, and Reynolds stress components in the Southern Hemisphere mesosphere-lower thermosphere in 2019
Read more of: Seasonal evolution of winds, atmospheric tides, and Reynolds stress components in the Southern Hemisphere mesosphere-lower thermosphere in 2019In this study we explore the seasonal variability of the mean winds and diurnal and semidiurnal tidal amplitude and phases, as well as the Reynolds stress components during 2019, utilizing […]

Remote control of Filchner‐Ronne Ice Shelf melt rates by the Antarctic Slope Current
Read more of: Remote control of Filchner‐Ronne Ice Shelf melt rates by the Antarctic Slope CurrentRecent work on the Filchner‐Ronne Ice Shelf (FRIS) system has shown that a redirection of the coastal current in the southeastern Weddell Sea could lead to a regime change in […]

Future risk for Southern Ocean ecosystem services under climate change
Read more of: Future risk for Southern Ocean ecosystem services under climate changeThe Southern Ocean supports ecosystem services that are important on a global scale. Climate change and human activities (tourism, fishing, and research) will affect both the demand for, and the […]

Changes in prey fields increase the potential for spatial overlap between gentoo penguins and a krill fishery within a marine protected area
Read more of: Changes in prey fields increase the potential for spatial overlap between gentoo penguins and a krill fishery within a marine protected areaAIM: Management of competition with predators is an important consideration for fisheries, particularly within marine protected areas (MPAs) where conservation is a primary objective. We aimed to test whether static […]

Ocean currents as a potential dispersal pathway for Antarctica’s most persistent non-native terrestrial insect
Read more of: Ocean currents as a potential dispersal pathway for Antarctica’s most persistent non-native terrestrial insectThe non-native midge Eretmoptera murphyi is Antarctica’s most persistent non-native insect and is known to impact the terrestrial ecosystems. It inhabits by considerably increasing litter turnover and availability of soil […]

Global drivers on Southern Ocean ecosystems: changing physical environments in an Earth system
Read more of: Global drivers on Southern Ocean ecosystems: changing physical environments in an Earth systemThe manuscript assesses the current and expected future global drivers of Southern Ocean (SO) ecosystems. Atmospheric ozone depletion over the Antarctic since the 1970s, has been a key driver, resulting […]

Measuring changes in snowpack SWE continuously on a landscape scale using lake water pressure
Read more of: Measuring changes in snowpack SWE continuously on a landscape scale using lake water pressureThe seasonal snowpack is a globally important water resource that is notoriously difficult to measure. Existing instruments make measurements of falling or accumulating snow water equivalent (SWE) that are susceptible […]

Variation among colonies in breeding success and population trajectories of wandering albatrosses Diomedea exulans at South Georgia
Read more of: Variation among colonies in breeding success and population trajectories of wandering albatrosses Diomedea exulans at South GeorgiaThe wandering albatross, Diomedea exulans, is a globally threatened species breeding at a number of sites within the Southern Ocean. Across the South Georgia archipelago, there are differences in population […]

Resilience in Greenland intertidal Mytilus: The hidden stress defense
Read more of: Resilience in Greenland intertidal Mytilus: The hidden stress defenseThe Arctic is experiencing particularly rapid rates of warming, consequently invasive boreal species are now able to survive the less extreme Arctic winter temperatures. Whilst persistence of intertidal and terrestrial […]
