Species distribution models describe spatial variability in mesopelagic fish abundance in the Southern Ocean
Read more of: Species distribution models describe spatial variability in mesopelagic fish abundance in the Southern OceanMesopelagic fishes play a central role in the transfer of energy through open-ocean food webs, particularly in the Southern Ocean where they are both important predators of zooplankton and a […]

Evolution of an accretionary complex (LeMay Group) and terrane translation in the Antarctic Peninsula
Read more of: Evolution of an accretionary complex (LeMay Group) and terrane translation in the Antarctic PeninsulaThe LeMay Group accretionary complex of Alexander Island (Antarctic Peninsula) comprises a 4 km thick succession of variably deformed turbidites associated with thrust slices of ocean floor basalts. The depositional […]

Bendocapillary Instability of Liquid in a Flexible-Walled Channel
Read more of: Bendocapillary Instability of Liquid in a Flexible-Walled ChannelWe study the bendocapillary instability of a liquid droplet that part fills a flexible walled channel. Inspired by experiments in which a periodic pattern emerges as droplets of liquid are […]

Planktic foraminifera iodine/calcium ratios from plankton tows
Read more of: Planktic foraminifera iodine/calcium ratios from plankton towsPlanktic foraminifera test iodine to calcium ratios represent an emerging proxy method to assess subsurface seawater oxygenation states. Several core-top studies show lower planktic foraminifera I/Ca ratios in locations with […]

Antarctica as a ‘natural laboratory’ for the critical assessment of the archaeological validity of early stone tool sites
Read more of: Antarctica as a ‘natural laboratory’ for the critical assessment of the archaeological validity of early stone tool sitesLithic technologies dominate understanding of early humans, yet natural processes can fracture rock in ways that resemble artefacts made by Homo sapiens and other primates. Differentiating between fractures made by […]

Levels and distribution profiles of Per- and Polyfluoroalkyl Substances (PFAS) in a high Arctic Svalbard ice core
Read more of: Levels and distribution profiles of Per- and Polyfluoroalkyl Substances (PFAS) in a high Arctic Svalbard ice corePer- and polyfluoroalkyl substances (PFAS) are a group of persistent organic contaminants of which some are toxic and bioaccumulative. Several PFAS can be formed from the atmospheric degradation of precursors […]

Variability of the shelf circulation around South Georgia, Southern Ocean
Read more of: Variability of the shelf circulation around South Georgia, Southern OceanA high-resolution ocean model is used to characterize the variability of the shelf circulation and cross-shelf transport around the South Georgia island (SG). The time-mean shelf circulation consists of a […]

Plasma-neutral interactions in the lower thermosphere-ionosphere: The need for in situ measurements to address focused questions
Read more of: Plasma-neutral interactions in the lower thermosphere-ionosphere: The need for in situ measurements to address focused questionsThe lower thermosphere-ionosphere (LTI) is a key transition region between Earth’s atmosphere and space. Interactions between ions and neutrals maximize within the LTI and in particular at altitudes from 100 […]

Annotating very high-resolution satellite imagery: A whale case study
Read more of: Annotating very high-resolution satellite imagery: A whale case studyThe use of very high-resolution (VHR) optical satellites is gaining momentum in the field of wildlife monitoring, particularly for whales, as this technology is showing potential for monitoring the less […]

Ecological consequences of a single introduced species to the Antarctic: Terrestrial impacts of the invasive midge Eretmoptera murphyi on Signy Island
Read more of: Ecological consequences of a single introduced species to the Antarctic: Terrestrial impacts of the invasive midge Eretmoptera murphyi on Signy IslandThe nutrient-poor soils of Antarctica are sensitive to change. Recent increases in the number of anthropogenic introductions mean that understanding the impact of non-native species on Antarctic soils is pertinent, […]

Climatological predictions of the auroral zone locations driven by moderate and severe space weather events
Read more of: Climatological predictions of the auroral zone locations driven by moderate and severe space weather eventsAuroral zones are regions where, in an average sense, aurorae due to solar activity are most likely spotted. Their shape and, similarly, the geographical locations most vulnerable to extreme space […]
