Levels and seasonal trends of C1-C4 perfluoroalkyl acids and the discovery of trifluoromethane sulfonic acid in surface snow in the Arctic
Read more of: Levels and seasonal trends of C1-C4 perfluoroalkyl acids and the discovery of trifluoromethane sulfonic acid in surface snow in the ArcticC1–C4 perfluoroalkyl acids (PFAAs) are highly persistent chemicals that have been found in the environment. To date, much uncertainty still exists about their sources and fate. The importance of the […]

Exploring the coupled ocean and atmosphere system with a data science approach applied to observations from the Antarctic Circumnavigation Expedition
Read more of: Exploring the coupled ocean and atmosphere system with a data science approach applied to observations from the Antarctic Circumnavigation ExpeditionThe Southern Ocean is a critical component of Earth’s climate system, but its remoteness makes it challenging to develop a holistic understanding of its processes from the small scale to […]

Can a key boreal Calanus copepod species now complete its life-cycle in the Arctic? Evidence and implications for Arctic food-webs
Read more of: Can a key boreal Calanus copepod species now complete its life-cycle in the Arctic? Evidence and implications for Arctic food-websThe changing Arctic environment is affecting zooplankton that support its abundant wildlife. We examined how these changes are influencing a key zooplankton species, Calanus finmarchicus, principally found in the North […]

Evolutionary innovations in Antarctic brittle stars linked to glacial refugia
Read more of: Evolutionary innovations in Antarctic brittle stars linked to glacial refugiaThe drivers behind evolutionary innovations such as contrasting life histories and morphological change are central questions of evolutionary biology. However, the environmental and ecological contexts linked to evolutionary innovations are […]

Kinetic energy transfers between mesoscale and submesoscale motions in the open ocean’s upper layers
Read more of: Kinetic energy transfers between mesoscale and submesoscale motions in the open ocean’s upper layersMesoscale eddies contain the bulk of the ocean’s kinetic energy (KE), but fundamental questions remain on the cross-scale KE transfers linking eddy generation and dissipation. The role of submesoscale flows […]

Shine a light: Under-ice light and its ecological implications in a changing Arctic Ocean
Read more of: Shine a light: Under-ice light and its ecological implications in a changing Arctic OceanThe Arctic marine ecosystem is shaped by the seasonality of the solar cycle, spanning from 24-h light at the sea surface in summer to 24-h darkness in winter. The amount […]

Influence of Orography Upon Summertime Low-Level Jet Dust Emission in the Central and Western Sahara
Read more of: Influence of Orography Upon Summertime Low-Level Jet Dust Emission in the Central and Western SaharaLow-level jets (LLJs) drive frequent emission of mineral dust in the central and western Sahara in boreal summer. A major hotspot for this process is central Algeria, northern Mali and […]

Using Predicted Patterns of 3D Prey Distribution to Map King Penguin Foraging Habitat
Read more of: Using Predicted Patterns of 3D Prey Distribution to Map King Penguin Foraging HabitatKing penguins (Aptenodytes patagonicus) are an iconic Southern Ocean species, but the prey distributions that underpin their at-sea foraging tracks and diving behaviour remain unclear. We conducted simultaneous acoustic surveys […]

Infrasound as a cue for seabird navigation
Read more of: Infrasound as a cue for seabird navigationSeabirds are amongst the most mobile of all animal species and spend large amounts of their lives at sea. They cross vast areas of ocean that appear superficially featureless, and […]

Microstructure and crystallographic preferred orientations of an azimuthally oriented ice core from a lateral shear margin: Priestley Glacier, Antarctica
Read more of: Microstructure and crystallographic preferred orientations of an azimuthally oriented ice core from a lateral shear margin: Priestley Glacier, AntarcticaA 58 m long azimuthally oriented ice core has been collected from the floating lateral sinistral shear margin of the lower Priestley Glacier, Terra Nova Bay, Antarctica. The crystallographic preferred […]
