Density-dependent prey depletion around breeding colonies has long been considered an important factor controlling the population dynamics of colonial animals. Ashmole proposed that as seabird colony size increases, intraspecific competition […]
Body-mounted accelerometers provide a new prospect for estimating power use in flying birds, as the signal varies with the two major kinematic determinants of aerodynamic power: wingbeat frequency and amplitude. […]
In this study, we present distributional data for Belgica antarctica (Diptera, Chironomidae), the only endemic insect species occurring naturally throughout the west coast of the Antarctic Peninsula and its offshore […]
Crystallographic preferred orientations (CPOs) are particularly important in controlling the mechanical properties of glacial shear margins. Logistical and safety considerations often make direct sampling of shear margins difficult, and geophysical […]
Tidal variability in the mesosphere and lower thermosphere (MLT) during September 2019 Southern hemisphere minor sudden stratospheric warming (SSW) is investigated utilizing ground-based meteor radar wind observations from the equatorial, […]
The combination of the Pine Island Ice Shelf (PIIS) draft and a seabed ridge beneath it form a topographic barrier, restricting access of warm Circumpolar Deep Water to a cavity […]
Following the cessation of whaling, the southwest Atlantic humpback whale (Megaptera novaeangliae) population is thought to be close to pre-exploitation size, reversing 20th century changes in abundance. Using a model-based […]
The satellite-observed sea ice thickness records from 2003 to 2020 identify an extreme sea ice thickness loss during 2010–2011. Ice thickness budget analysis demonstrates that the thickness loss was associated […]
We use meteorological measurements from three drifting buoys to evaluate the performance of the ERA-Interim and ERA5 atmospheric reanalyses from the European Centre for Medium-Range Weather Forecasts over the Weddell […]
Marine plastic pollution is a global and pervasive environmental issue. Knowledge on plastic degradation in natural settings is still very limited due to current technological limitations, hampering our understanding of […]
Reconstructing the advance and retreat of past ice sheets provides important long-term context for recent change(s) and enables us to better understand ice sheet responses to forcing mechanisms and external […]
Knowledge of the three-dimensional movement patterns of elasmobranchs is vital to understand their ecological roles and exposure to anthropogenic pressures. To date, comparative studies among species at global scales have […]
