Interactions between eddies and mean flow are essential to close the momentum budget of the Southern Ocean, as well as to determine the structure of the global meridional overturning circulation. […]
The meiobenthic community of Potter Cove (King George Island, west Antarctic Peninsula) was investigated, focusing on responses to summer/winter conditions in two study sites contrasting in terms of organic matter […]
The introduction of non-native species to Antarctica in association with human activities is a major threat to indigenous biodiversity and the region’s unique ecosystems, as has been well-demonstrated in other […]
Living organisms on Earth are characterized by three necessary features: a set of internal instructions encoded in DNA (software), a suite of proteins and associated macromolecules providing a boundary and […]
General Circulation Model simulations of the mid-Pliocene warm period (mPWP, 3.264 to 3.025 Myr ago) currently underestimate the level of warming that proxy data suggest existed at high latitudes, with […]
Patterns of environmental spatial structure lie at the heart of the most fundamental and familiar patterns of diversity on Earth. Antarctica contains some of the strongest environmental gradients on the […]
Fluctuations in Late Cretaceous climate were already influencing biotic change prior to the environmental upheaval at the Cretaceous – Paleogene (K–Pg) boundary, but their general nature, magnitude and timing remain […]
Carry-over effects have major implications for individual fitness and population and evolutionary dynamics. The strength of these effects is dependent on an individual’s intrinsic performance and the environmental conditions it […]
Antarctic krill are known to have strong swimming capabilities, but direct observations of the speed and direction of krill-swarm movement within their natural environment are rare. We identified and examined […]
Sub-ionospheric radio-wave data from an AARDDVARK receiver located in Churchill, Canada, is analysed to determine the characteristics of electron precipitation into the atmosphere over the range 3 30 keV precipitation fluxes of […]
Antarctic and Southern Ocean (ASO) marine ecosystems have been changing for at least the last 30 years, including in response to increasing ocean temperatures and changes in the extent and […]
The horizontal and vertical circulation of the Weddell Gyre is diagnosed using a box inverse model constructed with recent hydrographic sections and including mobile sea ice and eddy transports. The […]
