Marine Currents & the Antarctic
Shipboard oceanographic measurements aboard Scott's ship, the Terra Nova, led to the discovery that marine currents circle the Antarctic continent, much colder than the water further north.
Since then, scientists have concluded these currents form a natural barrier that has allowed Antarctic marine life to develop along their own evolutionary path.
Scott's scientists at both the winter quarters on Ross Island and on ship voyages also pulled up dozens of examples of strange new sea life.
They discovered new species of benthic organisms like brittle stars, mollusks, crustaceans, worms corals and sponges that hadn't been seen before, as well as new kinds of fish. The Terra Nova expedition in total brought back 40,000 new specimens to England, (including rocks and animal life).
