What are conditions like at the center of a gyre?

Expert Solution
To determine

The conditions existing at the center of a gyre.

Explanation of Solution

A gyre represents a circuit of currents driven by wind, flowing around the boundary of an ocean basin. Six major gyres exist in the world ocean, which include the North Pacific, South Pacific, Indian Ocean, North Atlantic, South Atlantic, and West-Wind Drift.

The gyres will usually exhibit the fastest movement of water along its margin or periphery. The centers of the gyres are generally calm with a higher relative salinity.  The current flow is negligible at the gyre centers. These regions favor the growth of comparatively little life...
