Abstract
This paper presents combined conductivity-temperature-depth (CTD), thermistor chain, current meter, and acoustic backscatter observations of a tidal front observed in the Chesapeake Bay. The data were obtained from a moored platform as the front migrated past the platform. The thermistor chain and CTD data show an interface that slopes steeply down from the surface to an asymptotic depth of 6 m, marking the bottom of the light-water pool. The thermistor chain data show much higher activity levels within the light-water pool as compared to the dense-water pool. Current meter data taken at 3 m show a pronounced shear in the currents upon crossing the frontal boundary. The acoustic backscatter from a layer of copepods positioned on the interface shows episodic occurrences of overturning at the interface. This observation is borne out by the concurrent thermistor chain data, which also show the overturning events.
