State of the Climate in 2024. Antarctica and the Southern Ocean
Read more of: State of the Climate in 2024. Antarctica and the Southern OceanIn 2024, atmospheric conditions over Antarctica exhibited significant anomalies, and were marked by major surface and stratospheric warming and pressure fluctuations. The first half of the year (January–June) featured persistent […]

Aspects of the Global Thermohaline Circulation in the Absence of Wind Forcing
Read more of: Aspects of the Global Thermohaline Circulation in the Absence of Wind ForcingThe global ocean’s overturning circulation plays an important role in climate and climate variability through its transport of heat, freshwater and nutrients. As part of this three-dimensional overturning circulation, dense […]

Coupling fragmentation to a size-selective sedimentation model can quantify the long-term fate of buoyant plastics in the ocean
Read more of: Coupling fragmentation to a size-selective sedimentation model can quantify the long-term fate of buoyant plastics in the oceanPlastic pollution in the ocean is a global environmental issue, with buoyant debris accumulating at the surface and posing long-term ecological threats. Although sediments are the ultimate sink for plastics, […]

Seasonal analysis of Southern Ocean copepod ecology using a moored sediment trap
Read more of: Seasonal analysis of Southern Ocean copepod ecology using a moored sediment trapThe Southern Ocean is a globally significant site of carbon sequestration with the copepod community exerting a strong influence on the carbon flux. Currently, a holistic understanding of Southern Ocean […]

Spatio-temporal melt and basal channel evolution on Pine Island Glacier ice shelf from CryoSat-2
Read more of: Spatio-temporal melt and basal channel evolution on Pine Island Glacier ice shelf from CryoSat-2Ice shelves buttress the grounded ice sheet, restraining its flow into the ocean. Mass loss from these ice shelves occurs primarily through ocean-induced basal melting, with the highest melt rates […]

Heated settlement plates (HSPl) in global experimentation: Experiences, research questions, future applications and collaborations
Read more of: Heated settlement plates (HSPl) in global experimentation: Experiences, research questions, future applications and collaborationsPredicting how benthic assemblages respond to ocean warming remains a central challenge in marine ecology. Artificial units of habitat such as settlement plates have long been used to study marine […]

Subglacial geology and palaeo flow of Pine Island Glacier from combining glacial erratics with geophysics
Read more of: Subglacial geology and palaeo flow of Pine Island Glacier from combining glacial erratics with geophysicsSubglacial geology plays a key role in determining the rate of ice flow and sensitivity of the glacial system to atmospheric or ocean warming. However, bedrock geology is often poorly […]

Climate Change, Fisheries Management, and Increases in Demersal Fish Distribution in a Southern Ocean Biodiversity Hotspot
Read more of: Climate Change, Fisheries Management, and Increases in Demersal Fish Distribution in a Southern Ocean Biodiversity HotspotThe world’s oceans and their biodiversity are undergoing change driven by climate change and anthropogenic impacts such as fishing. The Kerguelen Plateau is a biodiversity hotspot with many endemic fish […]

Variability of the Kinetic Energy in Seasonally Ice‐Covered Oceans
Read more of: Variability of the Kinetic Energy in Seasonally Ice‐Covered OceansThe seasonality of Arctic sea ice cover significantly influences heat, salt, buoyancy fluxes, ocean-ice stresses, and the potential and kinetic energy stored in the ocean mixed layer. This study examines […]

Monitoring shear-zone weakening in East Antarctic outlet glaciers through differential InSAR measurements
Read more of: Monitoring shear-zone weakening in East Antarctic outlet glaciers through differential InSAR measurementsThe stability of the Antarctic Ice Sheet depends on ice flux into the ocean through major outlet glaciers, which is resisted by shear stresses in the lateral shear margins, both […]
