The Gulf Stream is part of a general clockwise 
rotating system of currents in the North Atlantic. 
It is fed by the westward-flowing North 
Equatorial Current moving from North Africa to 
the West Indies. It was first described by the 
Spanish navigator and explorer Juan Ponce de 
León early in the 16th century. In 1844 
systematic surveying of the stream was begun. 
The marine organisms of the Gulf Stream system 
are not of great commercial value. Its warm 
waters, however, in mingling with the colder 
waters both on the Grand Banks and off north-
western Europe, contribute to turbulence and the 
availability of nutrient salts that made these 
regions amongst the most productive commercial 
fishing grounds in the world until they were 
overfished in the 1980s and early '90s. (d,b,b)
