The Loop Current is a flow of warm water that travels through the Gulf of Mexico, past the Florida Keys, and up the Atlantic Seaboard. ... This forms the Gulf Loop Current, which curves east and south along Florida's coast and exits through the Straits of Florida.

Explanation:

The 4-20 mA current loop has been the standard for signal transmission and electronic control in control systems since the 1950's. In a current loop, the current signal is drawn from a dc power supply, flows through the transmitter, into the controller and then back to the power supply in a series circuit.
