Mesoscale and submesoscale wavenumber spectra from the Geostationary Ocean Color Imager (GOCI)

Abstract

The Geostationary Ocean Color Imager (GOCI) continuously monitors the northeast Asian waters around Korea with 500 m horizontal resolution. These high resolution ocean color data enable us to study submesoscale processes much smaller than 10 km as well as mesoscales. Two regions, one in the southwestern part of East Sea (128-134°E and 35-39°N) and the other in the western Pacific south of the Kuroshio (132 - 142°E and 25 - 29°N), were selected. We then conducted spectral analysis using the bootstapping method for summer and winter respectively.0 km as well as mesoscales.
