This Atlas of the Patagonian Sea. Species and Spaces is a summary of information on the use made of the ecosystem of the Patagonian Sea by seabirds and marine mammals. These top predators require considerable space and resources and are vulnerable to many human activities. This makes them good indicators of the status of conservation of the ecosystem.
The detailed analysis contained in this Atlas provides useful basic scientific information essential for implementing the vision of integrated ecosystem management. In particular it suggests that there is a need to create a network of marine areas, under special considerations of biodiversity management, which will incorporate those open sea environments which are linked to key coastal areas.
The Patagonian Sea
The Patagonian Sea is the oceanic ecosystem of the South-Western Atlantic, exposed to the ecological effects of the fronts created by the Brazil and Malvinas currents. It is a unique, highly productive ocean which is plentiful in species of high aesthetic, ecological and economic value, but it is also vulnerable.
The limits of the Patagonian Sea are: the coasts of southern Brazil, Uruguay and Argentina and the meridian of 75°W to the west, the meridian of 50°W to the east, the point of contact of meridian 50°W with the Brazilian coast to the north, and parallel 60°S to the south.
