North Atlantic Current North Atlantic Current The North Atlantic Current (NAC), also known as North Atlantic Drift and North Atlantic Sea Movement, is a powerful warm western boundary current within the Atlantic Ocean that extends the Gulf Stream northeastward. The NAC originates from where the Gulf Stream turns north at the Southeast Newfoundland Rise, a submarine ridge that stretches southeast from the Grand Banks. The NAC flows northward east of the Grand Banks, from 40°N to 51°N, before turning sharply east to cross the Atlantic. It transports more warm tropical water to northern latitudes than any other boundary current; more than 40 Sv
Atlantic puffin puffin is a bird of the colder waters of the North Atlantic Ocean. It breeds on the coasts of north west Europe, the Arctic fringes and eastern North America. More than 90% of the global population is found in Europe (4,770,000–5,780,000 pairs, equalling 9,550,000–11,600,000 adults) and colonies in Iceland alone are home to 60% of the world's Atlantic puffins. The largest colony in the western Atlantic (estimated at more than 260,000 pairs) can be found at the Witless Bay Ecological Reserve, south of St. John's, Newfoundland and Labrador. Other major breeding locations include the north and west coasts of Norway,
