Loop Current that planktonic species likewise avoid the higher temperatures in these features. Loop Current A parent to the Florida Current, the Loop Current is a warm ocean current that flows northward between Cuba and the Yucatán Peninsula, moves north into the Gulf of Mexico, loops east and south before exiting to the east through the Florida Straits and joining the Gulf Stream. The Loop Current is an extension of the of the western boundary current of the North Atlantic subtropical gyre. Serving as the dominant circulation feature in the Eastern Gulf of Mexico, the Loop Currents transports between 23 and 27
North Atlantic Gyre warms. This is due to a weakening of the westerly winds, resulting in reduced wind stress and heat exchange, providing a greater period of time for the gyre water temperatures to rise. Collections of aerosols, marine particles, and ocean water in the North Atlantic Gyre from 1990-1992 have led to measurements in lead isotope ratios. These measurements exceed those associated with atmospheric pollution carried from Europe by the trade winds, implying that the majority of lead contamination in the gyre in the early 1990s was primarily caused by American emissions. The surface layers of the Sargasso Sea were used to
