Compensation Currents


horizontal movements of water masses that make up for loss of water in a given part of an ocean, sea, or lake.

Compensation currents may develop in both the surface and deep-lying layers of the water. The inter-trade-wind (equatorial) countercurrents of the Pacific, Atlantic, and Indian oceans are examples of compensation currents.
