Burned area mapping across the Arctic-boreal zone with Landsat and Sentinel-2 imagery
Read more of: Burned area mapping across the Arctic-boreal zone with Landsat and Sentinel-2 imageryWildfires in the Arctic-boreal zone have increased in frequency over recent decades, carrying substantial ecological, social, and economic consequences. Remote sensing is crucial for mapping burned areas, monitoring wildfire dynamics, […]

Hiss Wave Evolution During Substorms Based on Van Allen Probes Observations
Read more of: Hiss Wave Evolution During Substorms Based on Van Allen Probes ObservationsHiss waves frequently occur in the plasmasphere or plumes, playing a key role in energetic electron loss in the Earth’s inner magnetosphere. While previous studies have linked hiss wave enhancements […]

Neighbourly Dispute at the Edge of Life: Species Interactions Among Antarctic Mosses
Read more of: Neighbourly Dispute at the Edge of Life: Species Interactions Among Antarctic MossesQuestion: The stress gradient hypothesis predicts that extreme environments favour positive over negative species interac-tions, that is, facilitation over competition. However, along the Antarctic Peninsula (maritime Antarctic), we observed indirectevidence […]

Southern Ocean Vertical Carbon Stratification Across the Mid‐Pleistocene Transition
Read more of: Southern Ocean Vertical Carbon Stratification Across the Mid‐Pleistocene TransitionPaleoceanographic evidence detailing the evolution of ocean carbon sequestration at high resolution across the Mid-Pleistocene Transition (MPT; 1.2–0.7 Ma, million years ago) remains scarce. Here, we present a continuous record […]

Topographic effects of Svalbard on warm and moist air intrusions into the Central Arctic
Read more of: Topographic effects of Svalbard on warm and moist air intrusions into the Central ArcticWarm air intrusions (WAIs) along the North Atlantic pathway are key drivers of warm extremes in the central Arctic. The Svalbard archipelago acts as a major topographic barrier in the […]

High-resolution XRF-CS/ICP-MS mineral element data calibration and potential applications in sub-Antarctic peat records
Read more of: High-resolution XRF-CS/ICP-MS mineral element data calibration and potential applications in sub-Antarctic peat recordsPeatlands are important environmental archives and mineral dust trapped in peat cores from multiple sites can be used to track past changes in hemispheric and global wind circulation patterns. X-ray […]

Individualised niches: an integrative conceptual framework across behaviour, ecology, and evolution
Read more of: Individualised niches: an integrative conceptual framework across behaviour, ecology, and evolutionIndividuals differ. While seemingly trivial, this insight has nevertheless led to paradigm shifts, as three key fields of organismal biology have seen marked changes in key concepts over the past […]

Investigating high pathogenicity avian influenza virus incursions to remote islands: detection of H5N1 on Gough Island in the South Atlantic Ocean
Read more of: Investigating high pathogenicity avian influenza virus incursions to remote islands: detection of H5N1 on Gough Island in the South Atlantic OceanUnderstanding the mechanisms underlying the emergence and spread of high pathogenicity avian influenza virus(HPAIV) is critical for tracking its global dissemination, particularly via migratory seabirds, given their role intransmission over […]

Discovery of Antarctic moulting sites in satellite imagery reveals new threat to emperor penguins
Read more of: Discovery of Antarctic moulting sites in satellite imagery reveals new threat to emperor penguinsMoult is a critical period in the life cycle of emperor penguin. Like other stages of their life history they depend upon Antarctic sea-ice as a platform to moult. Our […]

A new coastal ice-core site identified in Dronning Maud Land, Antarctica, for high-resolution climate reconstructions to the Last Glacial Maximum
Read more of: A new coastal ice-core site identified in Dronning Maud Land, Antarctica, for high-resolution climate reconstructions to the Last Glacial MaximumHigh-resolution ice cores from the Antarctic Ice Sheet margin are crucial for reconstructing the climate history of Antarctica and the Southern Ocean. Ice-rise summits with stable positions and substantial snow […]
