Spatial segregation and bycatch risk as potential drivers of population trends of wandering albatrosses at South Georgia
Read more of: Spatial segregation and bycatch risk as potential drivers of population trends of wandering albatrosses at South GeorgiaSpatial segregation in at-sea distribution is frequently observed in seabirds and can have important implications for conservation and management. Globally, many albatross and petrel populations are declining due to bycatch […]

Simulation of the Measurement of Arctic Snow Thickness Using Ground-Penetrating Radar
Read more of: Simulation of the Measurement of Arctic Snow Thickness Using Ground-Penetrating RadarA dual-modality sensor combining ground-penerating radar and electromagnetic induction for the measurement of sea ice thickness is proposed. Though inductive sensing alone is widely used for ice thickness measurement over […]

Predicted deleterious mutations reveal the genetic architecture of male reproductive success in a lekking bird
Read more of: Predicted deleterious mutations reveal the genetic architecture of male reproductive success in a lekking birdDeleterious mutations are ubiquitous in natural populations and, when expressed, reduce fitness. However, the specific nature of these mutations and the ways in which they impact fitness remain poorly understood. […]

Decreasing mercury concentrations in beaks of the giant warty squid Moroteuthopsis longimana in the Scotia Sea (Southern Ocean) since the 1970s
Read more of: Decreasing mercury concentrations in beaks of the giant warty squid Moroteuthopsis longimana in the Scotia Sea (Southern Ocean) since the 1970sThe giant warty squid Moroteuthopsis longimana is an important prey of top predators in the Southern Ocean. It is therefore a major link in the pathway of contaminants like mercury […]

The Role of the Weather in the Fate of Shackleton’s Endurance
Read more of: The Role of the Weather in the Fate of Shackleton’s EnduranceEndurance, one of the main vessels of the Imperial Trans-Antarctic Expedition of 1914–17, became stuck and eventually was crushed by sea ice, sinking to the bottom of the Weddell Sea; […]

Refining Zooplankton Diet Composition Studies Over Short and Long Time Scales by Combining 18S Metabarcoding With Fatty Acid Analyses
Read more of: Refining Zooplankton Diet Composition Studies Over Short and Long Time Scales by Combining 18S Metabarcoding With Fatty Acid AnalysesUnderstanding diet composition is essential for unravelling trophic interactions in aquatic ecosystems. DNA metabarcoding, utilising various variable regions of the 18S rRNA gene, is increasingly employed to investigate zooplankton diet […]

The Impact of Adaptive High-Latitude Coordinates
Read more of: The Impact of Adaptive High-Latitude CoordinatesThe high-latitude ionosphere can be divided into three regions dominated by different types of coupling and characterized by distinctive behaviors. These are the polar cap, the auroral region, and the […]

The Representation of Surface Temperature Trends in C3S Seasonal Forecast Systems
Read more of: The Representation of Surface Temperature Trends in C3S Seasonal Forecast SystemsWe assess near‐surface temperature and sea surface temperature trends in 8 seasonal forecast systems in the Copernicus Climate Change Service archive, over the common hindcast period (1993–2016). All but one […]

Biological invasions: a global assessment of geographic distributions, long‐term trends, and data gaps
Read more of: Biological invasions: a global assessment of geographic distributions, long‐term trends, and data gapsBiological invasions are one of the major drivers of biodiversity decline and have been shown to have far‐reaching consequences for society and the economy. Preventing the introduction and spread of […]

Probabilistic precipitation downscaling for ungauged mountain sites: a pilot study for the Hindu Kush Himalaya
Read more of: Probabilistic precipitation downscaling for ungauged mountain sites: a pilot study for the Hindu Kush HimalayaThis study introduces a novel approach to post-processing (i.e. downscaling and bias-correcting) reanalysis-driven regional climate model daily precipitation outputs that can be generalised to ungauged mountain locations by leveraging sparse […]

Basal melt rate variability and tidal current vertical structure from observations beneath Ronne Ice Shelf, Antarctica
Read more of: Basal melt rate variability and tidal current vertical structure from observations beneath Ronne Ice Shelf, AntarcticaThis study examines the interplay between water column structure, tidal currents, and basal melting at a site beneath Ronne Ice Shelf, using a 3-year data set of oceanographic measurements, and […]
