Antarctic Ocean Legacy: Towards Protection of the Weddell Sea Region
Ice-bound, wild and remote, the Weddell Sea is a large, deep embayment nestled between the Antarctic Peninsula and Cape Norvegia. Lying south of the Atlantic Ocean, it is one of the most intact ecosystems in the world.At its widest, it is 2,000 km across, with the whole region encompassing 3.4 milli...
