Ocean current the windthe Coriolis effect plays a role in their behaviours. The thermohaline circulation is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. The adjective "thermohaline" derives from "thermo-" referring to temperature and "" referring to salt content, factors which together determine the density of sea water. Wind-driven surface currents (such as the Gulf Stream) travel polewards from the equatorial Atlantic Ocean, cooling en route, and eventually sinking at high latitudes (forming North Atlantic Deep Water). This dense water then flows into the ocean basins. While the bulk
Action in the North Atlantic going through hell-and-high-water, as 'Action in the North Atlantic' shows." An American oil tanker, the SS "Northern Star", captained by Capt. Steve Jarvis (Raymond Massey), is sunk in the North Atlantic Ocean by U-37, a German U-boat. Along with the First Officer, his friend Joe Rossi (Humphrey Bogart), they make it to a lifeboat loaded with other crewmen. When the U-Boat crew starts filming their plight, they respond with defiant gestures, and their lifeboat is rammed by the sub. The survivors swim to a raft and are finally rescued after 11 days adrift. During their brief liberty, Steve spends time
