Reclassifying Lethal Heat
As heatwaves increase in both frequency and intensity globally, the need to develop tools to predict the human impact and develop a more comprehensive understanding of the impact mechanism at […]

A fan-shaped subglacial basin province in East Antarctica formed by rotational extension
Read more of: A fan-shaped subglacial basin province in East Antarctica formed by rotational extensionRecent sub-ice topography investigations have imaged—with greatly improved detail—a set of low-elevation V-shaped basins hidden beneath a very large sector of the East Antarctic Ice Sheet. Here we jointly interpret […]

Estimating the contribution of the Irish Sea fish community to carbon sink potential
Read more of: Estimating the contribution of the Irish Sea fish community to carbon sink potentialThe marine biological carbon cycle plays a crucial role in the sinking and sequestration of atmospheric carbon and in regulating the global climate. Most existing research on biological carbon sequestration […]

First extinction risk assessment of a bryophyte species in Antarctica
Read more of: First extinction risk assessment of a bryophyte species in AntarcticaAssessing extinction risk is important for protecting species, as it is the starting point for conservation efforts. However, in Antarctica, none of the c. 116 species of bryophytes (the main […]

Antarctic science operations must account for climate change and extreme environmental events
Read more of: Antarctic science operations must account for climate change and extreme environmental eventsExtreme environmental events (EEEs) in Antarctica and the Southern Ocean are occurring with growing frequency and severity, and will become more pronounced under continued global warming. Antarctic research relies on […]

CMIP6 model biases in Antarctic stratospheric vortex dynamics and their implications for Southern Hemisphere circulation projections
Read more of: CMIP6 model biases in Antarctic stratospheric vortex dynamics and their implications for Southern Hemisphere circulation projectionsThe springtime variability of the stratospheric polar vortex over Antarctica is an important source of predictability for the Southern Annular Mode (SAM) and associated Southern Hemisphere (SH) regional climate anomalies […]

Atmospheric Dust Transport to High‐Elevation Dronning Maud Land, Antarctica, Modulated by Cyclonic Circulation, the Pacific Decadal Oscillation, and Source Emissions
Read more of: Atmospheric Dust Transport to High‐Elevation Dronning Maud Land, Antarctica, Modulated by Cyclonic Circulation, the Pacific Decadal Oscillation, and Source EmissionsThe dependence of aeolian dust transport on atmospheric circulation patterns allows dust preserved in Antarctic ice cores to serve as a proxy for past circulation variability. Here, we investigate dust […]

Assessing the Impact of Ground‐Based Wind Measurements on Mesospheric and Lower Thermospheric Weather Through Assimilation in a Whole Atmosphere Model
Read more of: Assessing the Impact of Ground‐Based Wind Measurements on Mesospheric and Lower Thermospheric Weather Through Assimilation in a Whole Atmosphere ModelThe mesosphere and lower thermosphere (MLT) dynamics play a crucial role in the vertical coupling of the whole atmosphere and are a key component of space weather processes. However, accurately […]

Oceanographic regime and foraging behaviour structure compound-specific PFAS variability in arctic-atlantic guillemots
Read more of: Oceanographic regime and foraging behaviour structure compound-specific PFAS variability in arctic-atlantic guillemotsCurrent chemical exposures studies characterise chemical risk through mean-based concentrations, treating individual-level variability as statistical noise. However, this variability may carry structured ecological information that mean-based approaches systematically overlook. Here, […]

Temperature history determines the adult size and maturation rates in seasonal cohorts of Loligo forbesii squid
Read more of: Temperature history determines the adult size and maturation rates in seasonal cohorts of Loligo forbesii squidWe hypothesised that the large variation observed in squid life-cycle traits, such as growth rate and size and age at maturity, is a consequence of extended breeding throughout the year. […]

Latest Pleistocene shrub expansion and steppe-tundra persistence in easternmost Beringia
Read more of: Latest Pleistocene shrub expansion and steppe-tundra persistence in easternmost BeringiaThe collapse of the mammoth steppe ecosystem at the end of the Pleistocene fundamentally restructured northern communities across Beringia, yet the spatial variability of this transition remains poorly understood. We […]

Climate-Driven Mobilization of Rare Earth Elements and Metals in Antarctica: Pathways, Ecological Exposure, and Implications for Trophic Transfer
Read more of: Climate-Driven Mobilization of Rare Earth Elements and Metals in Antarctica: Pathways, Ecological Exposure, and Implications for Trophic TransferClimate change is reshaping contaminant pathways in Antarctica by mobilizing rare earth elements (REEs) and heavy metals from the cryosphere into marine ecosystems. Thaw-driven changes in salinity, pH, stratification, and […]
