Selecting CMIP6 Models for Future Arctic Storylines Using a Novel Performance Score
Read more of: Selecting CMIP6 Models for Future Arctic Storylines Using a Novel Performance ScoreStorylines are physically plausible scenarios of future climate change, statistically derived from an ensemble of climate model projections and organized according to the magnitude of projected changes in two or […]

Challenges for ionosphere-thermosphere science
Read more of: Challenges for ionosphere-thermosphere scienceModelling the Ionosphere-Thermosphere system is one of the grand challenges for Earth system scientists. On 8 March 2024 the Royal Astronomical Society hosted a Specialist Discussion Meeting, with both online […]

Global Morphology of Chorus Waves in the Outer Radiation Belt and the Effect of Geomagnetic Activity and fpe/fce
Read more of: Global Morphology of Chorus Waves in the Outer Radiation Belt and the Effect of Geomagnetic Activity and fpe/fceChorus waves are naturally occurring plasma waves often observed in the terrestrial radiation belts that strongly influence the behavior of energetic electrons. These waves can both accelerate electrons to relativistic […]

Diversity of DNA viruses in the atmosphere of sub-Antarctic South Georgia
Read more of: Diversity of DNA viruses in the atmosphere of sub-Antarctic South GeorgiaStudying airborne viruses in remote environments like the sub-Antarctic island of South Georgia offers key insights into viral ecology, diversity, and their role in shaping ecosystems through microbial and nutrient […]

The marginal male hypothesis explains only small amounts of spatial variation in density in pinnipeds
Read more of: The marginal male hypothesis explains only small amounts of spatial variation in density in pinnipedsThe marginal male hypothesis is a mechanism proposed to explain gregariousness in pinnipeds. Here, we explore whether this mechanism, combined with density-dependent pup survival, can also account for heterogeneity in […]

Icebergs, jigsaw puzzles, and genealogy: automated multi-generational iceberg tracking and lineage reconstruction
Read more of: Icebergs, jigsaw puzzles, and genealogy: automated multi-generational iceberg tracking and lineage reconstructionTabular icebergs calve from ice shelves and glaciers in Antarctica, Greenland, and northern Ellesmere Island. These “ice islands”, as they are referred to in the Arctic, drift, melt, and fragment, […]

Response of emperor penguins to 40 years of changing ice conditions at the Astrid, Mertz and SANAE colonies using satellite remote sensing (1984–2024)
Read more of: Response of emperor penguins to 40 years of changing ice conditions at the Astrid, Mertz and SANAE colonies using satellite remote sensing (1984–2024)Emperor penguins are highly reliant on stable fast ice for successful breeding, and some studies project possible quasi-extinction for most colonies by 2100 due to future sea-ice loss. To better […]

Beringian flora and fauna from sedaDNA at Duvanny Yar, Sakha Republic, during marine isotope stages 2 and 3
Read more of: Beringian flora and fauna from sedaDNA at Duvanny Yar, Sakha Republic, during marine isotope stages 2 and 3Beringia’s extensive late Quaternary deposits of yedoma silt provide rich floristic and faunal records. Sampling of frozen yedoma exposures typically uses multiple baydzherakhs (residual silt heaps developed as conical thermokarst […]

Mineralogy and organic content are major predictors of shell loss in bivalves under reduced salinity, ocean freshening conditions
Read more of: Mineralogy and organic content are major predictors of shell loss in bivalves under reduced salinity, ocean freshening conditionsOcean freshening due to increased precipitation and ice melting in a warming world poses a significant threat to marine calcifiers. The reduced availability of calcification substrates and an undersaturated calcium […]

Wind‐Driven Coastal Polynya Variability Drives Decadal Ice‐Shelf Melt Variability in the Amundsen Sea
Read more of: Wind‐Driven Coastal Polynya Variability Drives Decadal Ice‐Shelf Melt Variability in the Amundsen SeaThe ice shelves in the Amundsen Sea are being melted rapidly by warm Circumpolar Deep Water(CDW), causing sea‐level rise. Ice‐shelf melt variability is controlled by the speed of a shelf‐break […]
