Oceanic pycnocline depth is usually inferred from in situ measurements.It is attempted to estimate the depth remotely.As solitary internal waves occur on oceanic pycnocline and propagate along it, it is possible to retrieve the depth indirectly in virtue of the solitary internal waves.A numerical model is presented for retrieving the pycnocline depth from synthetic aperture radar (SAR) images where the solitary internal waves are visible and when ocean waters are fully stratified.This numerical model is constructed by combining the solitary internal wave model and a two-layer ocean model.It is also assumed that the observed groups of solitary internal wave packets on the SAR imagery are generated by local semidiurnal tides.A case study in the East China Sea shows a good agreement with in situ CTD (conductivity-temperature-depth) data.
