Abstract

The Tasmanian Eastern Continental Shelf (TECS) has a complex internal wave field forced by surface tides and wind. To quantify these flow fields, we deployed three traditional moorings and two autonomous profilers on a transect across the relatively narrow shelf for 18 days in February 2015. These moorings provided temperature and velocity measurements through the water column. Harmonic analysis of the observed velocities indicates that time varying near-inertial waves are an order of magnitude more energetic than internal tides and dominate the internal wave field. We link variations in near-inertial wave velocities to variations in the surface wind stress.
