Interesting fact. Although Gulf Stream is the common name, it’s actually called the Florida Current between the Tortugas to about Jacksonville. In the Gulf of Mexico it’s called the Loop Current.
The Florida Current meets with the Antilles Current (which flows on the East side of the Bahamas) and becomes the Gulf Stream from there.
I still call it the Gulf Stream because no one would know what I was talking about.
Of interest to the fishermen, the current is strongest at the surface to about 300 feet. Velocity tappers to near zero at the bottom at 1500-1800 feet between Palm Brach and the Bahamas Bank. If the flow rate was constant through the water column, it wouldn’t take so much weight to get a bait to the bottom when drift fishing.
