A conceptual view on inertial internal waves in relation to the subinertial flow on the central west Florida shelf

Abstract The study reported here focuses on inertial internal wave currents on the west Florida midshelf in 50 m depth. In situ observations showed that the seasonal shifts in stratification change both the frequency range of inertial internal waves and their modulation time scales. According to the...
