The Gulf of Maine
Movement of water through the Gulf of Maine
Off the west side of Nova Scotia and the east coast of New Brunswick lies the Bay of Fundy. To the south, the Bay of Fundy joins the Gulf of Maine. As in the Gulf of St. Lawrence, the current in the Gulf of Maine moves in a counterclockwise direction. The current, fed by the Nova Scotia Current, flows out of the Bay of Fundy and along the coast of New Brunswick all the way to Cape Cod. The stream then turns northward and returns to the Bay of Fundy. The runoff from nearby rivers, along with the strong tides moving into the Gulf of Maine drive its currents. The circular movement is also directed by Coriolis forces, which are exerted by the Earth’s rotation on all objects at the Earth’s surface. Currents in the northern hemisphere generally move in a counterclockwise direction, while currents in the southern hemisphere tend to move in a clockwise direction.
