Gulf Stream in Europe (07:15)
Horta is a port city that many boats reach by following the North Atlantic Drift. The current is responsible for western European's mild climate. In Brittany, engineers are working on a new type of buoy to study the ocean at new depths.

A variety of plants can grow in northwest Ireland because of its proximity to the Gulf Stream. Seamus O'Donnell has an extensive nursery of exotic plants that he sells to others in the area. Glenveagh Castle is known for its gardens and greenhouses.

Experts believe settlers built Skara Brae in Orkney because of the good climate. Much of the north Atlantic region was settled because of the Gulf Stream.
Gulf Stream in Iceland (06:44)
The ice on the southwest coast of Iceland is from the Vatnajokull glacier. The warmth from the Gulf Stream keeps the rest of Iceland's coasts free of ice. Researchers are looking for the cause of changing water temperatures and how it could affect the Gulf Stream.
Gulf Stream in Lofoten Islands (08:27)
Cod fishing has been important to northern Norway since the time of the Vikings. The Gulf Stream brings nutrient-rich water near the coast that attracts cod. The islands have a warm climate because of the Gulf Stream.
