Arctic warming by abundant fine sea salt aerosols from blowing snow
The Arctic warms nearly four times faster than the global average, and aerosols play an increasingly important role in Arctic climate change. In the Arctic, sea salt is a major […]

Sequence stratigraphy of a wave-dominated, tidally influenced delta in the Danian of Seymour Island, Antarctica: An integrated sedimentological–palaeoecological approach
Read more of: Sequence stratigraphy of a wave-dominated, tidally influenced delta in the Danian of Seymour Island, Antarctica: An integrated sedimentological–palaeoecological approachLower Paleocene marine siliciclastics of the Sobral Formation (Seymour Island, Antarctica) form an important component of a key southern high latitude reference section for the Maastrichtian–Eocene. The formation comprises a […]

Unsupervised machine learning detection of iceberg populations within sea ice from dual-polarisation SAR imagery
Read more of: Unsupervised machine learning detection of iceberg populations within sea ice from dual-polarisation SAR imageryAccurate quantification of iceberg populations is essential to inform estimates of Southern Ocean freshwater and heat balances as well as shipping hazards. The automated operational monitoring of icebergs remains challenging, […]

Separating contributions to plasma vorticity in the high-latitude ionosphere from large-scale convection and meso-scale turbulence
Read more of: Separating contributions to plasma vorticity in the high-latitude ionosphere from large-scale convection and meso-scale turbulenceMeasurements of ionospheric flow vorticity can be used for studying ionospheric plasma transport processes, such as convection and turbulence, over a wide range of spatial scales. Here, we analyse probability […]

Sea-ice decline could keep zooplankton deeper for longer
Read more of: Sea-ice decline could keep zooplankton deeper for longerAs Arctic sea ice deteriorates, more light enters the ocean, causing largely unknown effects on the ecosystem. Using an autonomous biophysical observatory, we recorded zooplankton vertical distribution under Arctic sea […]

Sea Butterflies Defend Their Homes Against an Acidic Ocean
Read more of: Sea Butterflies Defend Their Homes Against an Acidic OceanWe all know that carbon dioxide (CO2) is produced from burning fossil fuels, and that it contributes to global warming. But have you heard about the “evil twin” of global […]

Record low 2022 Antarctic sea ice led to catastrophic breeding failure of emperor penguins
Read more of: Record low 2022 Antarctic sea ice led to catastrophic breeding failure of emperor penguinsThe spring season of 2022 saw record low sea ice extent in Antarctica that persisted throughout the year. At the beginning of December, the Antarctic sea ice extent was tracking […]

Antarctic Ice Sheet paleo-constraint database
Read more of: Antarctic Ice Sheet paleo-constraint databaseWe present a database of observational constraints on past Antarctic Ice Sheet changes during the last glacial cycle intended to consolidate the observations that represent our understanding of past Antarctic […]

Antarctic sedimentary basins and their influence on ice-sheet dynamics
Read more of: Antarctic sedimentary basins and their influence on ice-sheet dynamicsKnowledge of Antarctica’s sedimentary basins builds our understanding of the coupled evolution of tectonics, ice, ocean, and climate. Sedimentary basins have properties distinct from basement-dominated regions that impact ice-sheet dynamics, […]

Convective instabilities of electromagnetic ion cyclotron waves in the outer magnetosphere
Read more of: Convective instabilities of electromagnetic ion cyclotron waves in the outer magnetosphereThe path-integrated linear growth of electromagnetic ion cyclotron waves in the outer (L ≥ 7) magnetosphere is investigated using a realistic thermal plasma distribution with an additional anisotropic energetic ring […]
