Gulf Stream and Its Effects

The Gulf Stream is a warm, fast-moving ocean current originating in the Gulf of Mexico, flowing along the eastern U.S. coast, and crossing the Atlantic to become the North Atlantic Current. It is part of the North Atlantic Subtropical Gyre and influences climate by bringing warm water northward. Historically, it was discovered by Juan Ponce de Leon and later mapped by Benjamin Franklin. The Gulf Stream affects the climate of Florida and Europe, intensifies cyclones, and was crucial for navigation.
