Vessel biofouling management in Antarctica
Biofouling is the accumulation of marine organisms on submerged surfaces, which can facilitate the transport of organisms when biofouling grows on vessels or floating objects such as wood, plastic or […]

An extreme Antarctic event; 2025 was record low seasonal sea ice and record high iceberg scouring
Read more of: An extreme Antarctic event; 2025 was record low seasonal sea ice and record high iceberg scouringA profound change in the polar oceans has been the drastic loss of seasonal sea ice. Such marine ice has been recorded daily at Ryder Bay, Adelaide Island (Antarctica) since […]

Ray Tracing Method in a General Non‐Dipole Magnetic Field
Read more of: Ray Tracing Method in a General Non‐Dipole Magnetic FieldWe present a new general mathematical formulation of the Eikonal equations for ray tracing, which can use any internal magnetic field model. The analytical and tractable expressions are conveniently based […]

A pan-Arctic pigment database for phytoplankton and sea-ice algae
Read more of: A pan-Arctic pigment database for phytoplankton and sea-ice algaeClimate change has dramatically altered the Arctic seas with significant decrease in sea ice extent and thickness and warming water temperature. The ecological impacts of such change have been described […]

From white to green to blue? Trajectories of phytoplankton communities in a warming Southern Ocean
Read more of: From white to green to blue? Trajectories of phytoplankton communities in a warming Southern OceanThe Southern Ocean is experiencing warming, melting of ice, and increasing wind. Predictions of increasing phytoplankton biomass associated with warming and declining glacial and sea ice are supported by observations. […]

Antarctic snow algal responses to temperature – potential implications of climate change
Read more of: Antarctic snow algal responses to temperature – potential implications of climate changeSnow algae are important primary producers in Antarctic terrestrial ecosystems. As short-term Antarctic summer temperatures approach 20°C, parameterising temperature tolerance for snow algal species is key to determining how climate […]

Antarctic krill (Euphausia superba) swarm structure and biomass distribution around the South Orkney Islands (Southern Ocean)
Read more of: Antarctic krill (Euphausia superba) swarm structure and biomass distribution around the South Orkney Islands (Southern Ocean)Antarctic krill swarm structure, biomass, and distribution to the northwest of the South Orkney Islands, Southern Ocean, were investigated using a combination of acoustic and scientific net trawl data. Krill […]

Primary production in relation to algal species composition in a warming Western Antarctic peninsula
Read more of: Primary production in relation to algal species composition in a warming Western Antarctic peninsulaThe Western Antarctic Peninsula is a key area in the Southern Ocean ecosystem. Dense microalgal communities not only support diverse wildlife, but can also exert a climatic influence through CO2-uptake […]

Trophic ecology and niche segregation among coexisting Macrourus species at South Georgia, Southern Ocean
Read more of: Trophic ecology and niche segregation among coexisting Macrourus species at South Georgia, Southern OceanDespite their importance in food webs and predominance among species bycaught in Southern Ocean toothfish fisheries, the trophic ecology of grenadiers of the genus Macrourus, remains poorly understood. Here, we […]

Mass Loss From Thwaites Glacier Continues Even Without Ocean Melting
Read more of: Mass Loss From Thwaites Glacier Continues Even Without Ocean MeltingPine Island and Thwaites glaciers dominate Antarctica’s sea-level contribution. However, it remains unclear whether their ice loss is driven by anomalously warm present-day ocean conditions, perhaps linked to anthropogenic climate […]

Shallow evolutionary divergence in the Antarctic notothenioid genus Harpagifer across the Southern Ocean
Read more of: Shallow evolutionary divergence in the Antarctic notothenioid genus Harpagifer across the Southern OceanStrong biogeographic structure across the Southern Ocean has led to the recognition of multiple geographically restricted species in many coastal taxa. We examined evolutionary relationships within the Antarctic notothenioid fish […]

TundraFlux: a database of ecosystem respiration with biotic and abiotic metadata from Arctic and alpine tundra warming experiments [Data description article]
Read more of: TundraFlux: a database of ecosystem respiration with biotic and abiotic metadata from Arctic and alpine tundra warming experiments [Data description article]Empirical in-situ measurements of ecosystem carbon dioxide respiration (Reco) in high-latitude ecosystems remain limited, yet they are essential for understanding how tundra carbon cycling responds to climate warming across different […]
