Potential implications of climate change on the Patagonian toothfish fisheries management Azarian, C., L. Bopp and F. d'Ovidio
Resumen:
Climate change can impact fish stocks through different processes with two main impacts for a given stock: the migration of the stock and the decrease of its biomass. In the case of Patagonian toothfish, it seems unlikely that migration will occur due to the Read More

Resumen:
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

Climate drives long-term change in Antarctic Silverfish along the western Antarctic Peninsula Corso, A.D., D.K. Steinberg, S.E. Stammerjohn and E.J. Hilton
Resumen:
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. We utilized a novel 25-year (1993–2017) time series to model the effects of environmental Read More
