Seabirds and marine mammals as sentinels of global changes in the Southern Ocean

The program uses seabirds and marine mammals as indicators of global changes in the marine ecosystems of the southern ocean. Through a network of 4 observatories from the Antarctic to sub-tropical biomes, the populations of 25 species of marine top predators and their distribution at sea are monitored since 50 years. These individually based long term information, combined with shorter term studies carried out on an annual base, especially on the foraging ecology of the species, are used to understand the processes though which climate affects marine ecosystems, and to make predictions on the effects of future changes in these ecosystems, as well as to propose conservation measures to limit the impact of fisheries on populations.
