The Antarctic Circumpolar Current (ACC) is a hotspot for the generation of small-scale motions that have a key role in cross-frontal exchanges. We present the first analysis of surface currents in the ACC derived from high-resolution sea surface height (SSH)…
Understanding past climate is essential to our knowledge of how our current climate system operates, and how it might respond to future change. Techniques to reconstruct climate history are challenging, and both accuracy and certainty are hampered by the quality of the datasets used.
The Southern Ocean is disproportionately important in its effect on the Earth system, impacting climatic, biogeochemical, and ecological systems, which makes recent observed changes to this system cause for global concern.
The response of the global water cycle to changes in global surface temperature remains an outstanding question in future climate projections and in past climate reconstructions. The stable hydrogen and oxygen isotope compositions of precipitation (?precip), meteoric water (?MW) and seawater (?SW)…
Avian and mammalian predators play a key role in the Kerguelen Plateau ecosystem, both with respect to structuring the marine community and its response to anthropogenic influences, such as climate change and commercial fisheries.
ABSTRACT: Foraging movements of Adélie penguins are constrained both by environmental conditions … (e.g. sea ice cover) and life history factors (e.g. regular offspring provisioning). We describe … within season changes in foraging range…
