Which process primarily maintains the anticlockwise circulation of the North Pacific Subpolar Gyre?

💡 Explanation

When winds blow along the surface, Ekman transport deflects water, causing divergence, especially in subpolar regions due to bathymetry and wind patterns, drawing water upwards reinforcing geostrophic flow. Therefore, Ekman transport maintains the gyre current rather than blocking, altering salinity, or intensifying bottom water, all which require different inputs.
