It extends all the way up the eastern coast of the United States and Canada. The position of the Gulf Stream is always changing based on water temperatures and currents. This layer is derived from the Gulf Stream ASCII Data provided to the Ocean Prediction Center by the Naval Oceanographic Office (NAVO). The northern and southern wall boundary is updated daily.
