High foraging site fidelity and spatial segregation among individual great black‐backed gulls
Read more of: High foraging site fidelity and spatial segregation among individual great black‐backed gullsIndividual foraging site fidelity, whereby individuals repeatedly visit the same foraging areas, is widespread in nature, and likely benefits individuals through higher foraging efficiency and potentially, higher breeding success. It […]

West Antarctic surface melt triggered by atmospheric rivers
Read more of: West Antarctic surface melt triggered by atmospheric riversRecent major melting events in West Antarctica have raised concerns about a potential hydrofracturing and ice shelf instability. These events often share common forcings of surface melt-like anomalous radiative fluxes, […]

Southern Ocean wind stress in CMIP5 models: Role of wind fluctuations
Read more of: Southern Ocean wind stress in CMIP5 models: Role of wind fluctuationsThe Southern Ocean (SO) surface wind stress is a major atmospheric forcing for driving the Antarctic Circumpolar Current and the global overturning circulation. Here the effects of wind fluctuations at […]

Magmatism of the Weddell Sea rift system in Antarctica: Implications for the age and mechanism of rifting and early stage Gondwana breakup
Read more of: Magmatism of the Weddell Sea rift system in Antarctica: Implications for the age and mechanism of rifting and early stage Gondwana breakupThick (∼800 m) basaltic successions from the eastern Antarctic Peninsula have been dated in the interval 180 – 177 Ma and preserve a transition from a continental margin arc to […]

Nodosilinea signiensis sp. nov. (Leptolyngbyaceae, Synechococcales), a new terrestrial cyanobacterium isolated from mats collected on Signy Island, South Orkney Islands, Antarctica
Read more of: Nodosilinea signiensis sp. nov. (Leptolyngbyaceae, Synechococcales), a new terrestrial cyanobacterium isolated from mats collected on Signy Island, South Orkney Islands, AntarcticaTerrestrial cyanobacteria are very diverse and widely distributed in Antarctica, where they can form macroscopically visible biofilms on the surfaces of soils and rocks, and on benthic surfaces in fresh […]

Extremes in benthic ecosystem services; Blue carbon natural capital shallower than 1000 m in isolated, small and young Ascension Island’s EEZ
Read more of: Extremes in benthic ecosystem services; Blue carbon natural capital shallower than 1000 m in isolated, small and young Ascension Island’s EEZBiodiversity tends to decrease with increasing isolation and reduced habitat size, and increase with habitat age. Ascension Island and its seamounts are small, isolated and relatively young, yet, within its […]

Antarctic temperature variability and change from station data
Read more of: Antarctic temperature variability and change from station dataVariability and change in near‐surface air temperature at 17 Antarctic stations is examined using data from the SCAR READER database. We consider the relationships between temperature, and atmospheric circulation, sea […]

UKESM1: description and evaluation of the U.K. Earth System Model
Read more of: UKESM1: description and evaluation of the U.K. Earth System ModelWe document the development of the first version of the United Kingdom Earth System Model UKESM1. The model represents a major advance on its predecessor HadGEM2‐ES, with enhancements to all […]

Modeling satellite gravity gradient data to derive density, temperature, and viscosity structure of the Antarctic lithosphere
Read more of: Modeling satellite gravity gradient data to derive density, temperature, and viscosity structure of the Antarctic lithosphereIn this study we combine seismological and petrological models with satellite gravity gradient data to obtain the thermal and compositional structure of the Antarctic lithosphere. Our results indicate that Antarctica […]

The role of eddies and topography in the export of shelf waters from the West Antarctic Peninsula shelf
Read more of: The role of eddies and topography in the export of shelf waters from the West Antarctic Peninsula shelfOceanic heat strongly influences the glaciers and ice shelves along West Antarctica. Prior studies show that the subsurface onshore heat flux from the Southern Ocean on the shelf occurs through […]

The response of the ionosphere-thermosphere system to the August 21, 2017 solar eclipse
Read more of: The response of the ionosphere-thermosphere system to the August 21, 2017 solar eclipseWe simulated the effects of the 21 August 2017 total solar eclipse on the ionosphere‐thermosphere system with the Global Ionosphere Thermosphere Model (GITM). The simulations demonstrate that the horizontal neutral […]
