Internal Wave Observations Off Saba Bank

The deep sloping sides of Saba Bank, the largest submarine atoll in the Atlantic Ocean, show quite different internal wave characteristics. To measure these characteristics, two 350 m long arrays consisting of primary a high-resolution temperature T-sensor string and secondary an acoustic Doppler current profiler were moored around 500 m water depth at the northern and southern flanks of Saba Bank for 23 days. We observed that the surrounding density stratified waters supported large internal tides and episodically large turbulent exchange in up to 50 m tall overturns. However, an inertial sub... Mehr ...
