Snow and glacier algal blooms are increasingly well documented in the Northern Hemisphere, but their diversity and ecology in Antarctic regions remains poorly understood. Here, we present the outcomes of […]
As new airborne surveys of the Antarctic ice sheet are completed, the ever-enlarging survey dataset provides an opportunity for generating new ‘Bedmaps’ of ice thickness, surface and bed topography. These […]
Understanding lineage divergence is crucial for uncovering cryptic biodiversity. Adaptive divergence, geographic isolation and life-history traits drive speciation in heterogeneous environments. The gentoo penguin complex (Pygoscelis spp.), historically treated as […]
Ocean-driven basal melting of Antarctic ice shelves plays an important role in the mass loss of the Antarctic Ice Sheet. Ice shelf cavity-resolving ocean models are a valuable tool for […]
Thwaites Glacier in West Antarctica is losing ice rapidly and is considered especially vulnerable to retreat, but predictions of its future remain limited by uncertainties about its subglacial properties. Here […]
Giant Antarctic iceberg calving is projected to increase with climate change, affecting ocean circulation, nutrient supply, and carbon cycling. These icebergs can stimulate primary production and influence Southern Ocean carbon […]
Since the invention of echosounders and sonars in the early twentieth century, the applications of active-acoustic instruments have expanded from single-frequency range detection and fisheries stock estimates to wider explorations […]
The Atlantic Meridional Overturning Circulation (AMOC), a key component of the global climate system, behaves as a typical climate tipping element with multi-stable states. Changes in AMOC instigate a series […]
The interplay between interindividual phenotypic variation and epigenetic processes remains poorly understood in an ecoevolutionary context. Epigenetic variation is a key driver of individual differences, with genetically regulated, environmentally induced, […]
The proliferation of accessible deep-water imaging platforms has resulted in the acquisition of vast amounts of image data, resulting in an analysis bottleneck. Object detection is now being applied to […]
Monitoring benthic biodiversity in Antarctica is vital for understanding ecological change in response to climate-driven pressures. This work is typically performed using high-resolution imagery captured in situ, though manual annotation […]
As the world’s strongest zonal surface winds, changes in the Southern Hemisphere Westerlies (SHW) can profoundly affect atmospheric carbon dioxide (CO2) concentrations, ocean-cryosphere domains and precipitation patterns in the Southern […]
