Gulf Stream

Explanation:

Essentially, the Gulf Stream is a "river of water" in the ocean. It originates off the coast of Florida and flows north, until it splits in two just above the forty-fifth parallel. At the split, it becomes the North Atlantic Drift, one branch flowing toward Iceland, the other toward the continent of Europe.
