The water that forms these mounds tends to flow downhill, away from the center of the gyre; but the Coriolis Effect pushes the water back into the mound formation. These two forces (gravity, pushing the water in the mounds (downhill, or toward the surface of the Earth, and the Coriolis Effect, which forces the water back into the mounds’ centers) work together (or, rather, against one another) to create areas of circling water that can be very large.
Which of the following terms defines this compound phenomenon?

Sargassum Flow
Geostrophic Flow
Gyre-Coriolis Flow
Whirlpool Flow
