An evaluation of surface meteorology and fluxes over the Iceland and Greenland Seas in ERA5 reanalysis: The impact of sea ice distribution
Read more of: An evaluation of surface meteorology and fluxes over the Iceland and Greenland Seas in ERA5 reanalysis: The impact of sea ice distributionThe Iceland and Greenland Seas are a crucial region for the climate system, being the headwaters of the lower limb of the Atlantic Meridional Overturning Circulation. Investigating the atmosphere–ocean–ice processes […]

Meteorological impacts of a novel debris-covered glacier category in a regional climate model across a Himalayan catchment
Read more of: Meteorological impacts of a novel debris-covered glacier category in a regional climate model across a Himalayan catchmentMany of the glaciers in the Nepalese Himalaya are partially covered in a layer of loose rock known as debris cover. In the Dudh Koshi River Basin, Nepal, approximately 25% […]

Continuous moulting by Antarctic krill drives major pulses of carbon export in the north Scotia Sea, Southern Ocean
Read more of: Continuous moulting by Antarctic krill drives major pulses of carbon export in the north Scotia Sea, Southern OceanAntarctic krill play an important role in biogeochemical cycles and can potentially generate high-particulate organic carbon (POC) fluxes to the deep ocean. They also have an unusual trait of moulting […]

Inhibitory effects of climate change on the growth and extracellular enzyme activities of a widespread Antarctic soil fungus
Read more of: Inhibitory effects of climate change on the growth and extracellular enzyme activities of a widespread Antarctic soil fungusTemperatures approaching or exceeding 20 °C have been measured during summer in polar regions at the surfaces of barren fellfield soils under cloudless skies around solar noon. However, despite the […]

Assessment of the effects of isolation, confinement and hypoxia on spaceflight piloting performance for future space missions – The SIMSKILL experiment in Antarctica
Read more of: Assessment of the effects of isolation, confinement and hypoxia on spaceflight piloting performance for future space missions – The SIMSKILL experiment in AntarcticaInterplanetary human missions to Mars and beyond will suppose a very demanding physical and psychological environment for future astronauts. Isolation, confinement, hypoxia or hypercapnia in a less pressurized atmosphere, darkness […]

Glacial dynamics and deglaciation history of Hambergbukta reconstructed from submarine landforms and sediment cores, SE Spitsbergen, Svalbard
Read more of: Glacial dynamics and deglaciation history of Hambergbukta reconstructed from submarine landforms and sediment cores, SE Spitsbergen, SvalbardThe submarine landforms and shallow sediment record are presented from Hambergbukta, southeastern Spitsbergen using swath‐bathymetric, subbottom acoustic, and sediment core data. The mapped landforms include large terminal and end‐moraines with […]

Marine ecosystem assessment for the Southern Ocean: birds and marine mammals in a changing climate
Read more of: Marine ecosystem assessment for the Southern Ocean: birds and marine mammals in a changing climateThe massive number of seabirds (penguins and procellariiformes) and marine mammals (cetaceans and pinnipeds) – referred to here as top predators – is one of the most iconic components of […]

The role of curvature in modifying frontal instabilities. Part I: Review of theory and presentation of a nondimensional instability criterion
Read more of: The role of curvature in modifying frontal instabilities. Part I: Review of theory and presentation of a nondimensional instability criterionIn this study, we examine the role of curvature in modifying frontal stability. We first evaluate the classical criterion that the Coriolis parameter, f, multiplied by the Ertel potential vorticity […]

The role of curvature in modifying frontal instabilities. Part II: Application of the criterion to curved density fronts at low Richardson numbers
Read more of: The role of curvature in modifying frontal instabilities. Part II: Application of the criterion to curved density fronts at low Richardson numbersWe continue our study of the role of curvature in modifying frontal stability. In Part 1, we obtained an instability criterion valid for curved fronts and vortices in gradient wind […]

Reconciling the surface temperature–surface mass balance relationship in models and ice cores in Antarctica over the last 2 centuries
Read more of: Reconciling the surface temperature–surface mass balance relationship in models and ice cores in Antarctica over the last 2 centuriesIce cores are an important record of the past surface mass balance (SMB) of ice sheets, with SMB mitigating the ice sheets’ sea level impact over the recent decades. For […]
