This paper provides an overview of a new research project to evaluate climate change risks to toothfish in subareas 48.3 and 48.4. The CCAMLR Convention Area is one of the world’s most rapidly changing oceanic regions, with major impacts both observed and expected on marine ecosystems due to climate change and consequences for the conservation and management of marine living Read More

In face of the fast climate changes occurring in the Antarctic Peninsula, inclusion of climate change scenarios within the process of designation of Marine Protected Areas and krill fishing management is important. We conducted an exploratory analysis to evaluate changes of sea surface temperature and sea ice within the proposed Domain 1 Read More

Polar seafloor ecosystems are changing rapidly and dramatically, challenging previously held paradigms of extreme dynamical stability. Warming-related declines in polar sea ice are expected to alter fluxes of phytoplankton and under-ice algae to the seafloor. Coastal Antarctic regions are biodiverse and productive regions, covered in sea ice for much of the year. This land- Read More

Antarctica and Southern Ocean environments are changing rapidly in ways that are not always foreshadowed by model predictions. Using the examples of recent rapid reductions in sea ice areal cover and increased occurrence of extreme climate events, this paper recommends the development of an assessment of risk posed by possible changes to critical processes that fundamentally Read More

Over the last half of the 20th century, the western Antarctic Peninsula has been one of the most rapidly warming regions on Earth, leading to substantial reductions in regional sea ice coverage. These changes are modulated by atmospheric forcing, including the Amundsen Sea Low (ASL) pressure system.
