Latitude of the Gulf Stream and the Gulf Stream north wall index

The Gulf Stream separates from the US coast near Cape Hatteras (35°N, 75°W) and then travels eastwards across the North Atlantic, becoming the North Atlantic current at about 55°W. In the region between 75°W and 55°W it is subject to meanders and is frequently accompanied by eddies. The northern edge of the current is marked by a sharp fall in temperature.
