The Weddell Sea extents far south and is therefore under the direct influence of the very cold Antarctic Continental Climate. The continental borders of the Weddell Sea are formed by huge floating sheets of ice. These ice-shelves produce the huge tabular ice-bergs that are so abundant in the Weddell Sea. Scientists have declared the waters of the Weddell Sea to be the clearest water of any sea on Earth. The clarity of the water is on par with distilled water.
The Weddell Sea is frequented by a large number of Orcas, Humpback, and Minke Whales as well as Leopard, Weddell, and Crabeater Seals. The area is also home to a large number of penguins, namely the Adelie Penguins - who have a colony of more than 100,000 breeding pairs - which nest on Paulet Island. Recently a colony of Emperor Penguins was also found nearby on Snowhill Island.
The Weddell Sea was discovered by the British sealer James Weddell in 1823.
