Hydrographic observations made with an undulating vehicle carrying a CTD and concurrent shipboard ADCP velocity observations over a 12‐day period are combined to investigate vertical mixing and cross‐frontal fluxes on the Northern Flank of Georges Bank. The CTD density time series is analyzed to detect the presence of vertical overturns,...
By mapping the three-dimensional density field while simultaneously tracking a subsurface, isopycnal float, direct observations of upwelling along a shelfbreak front were made on the southern flank of Georges Bank. The thermohaline and bio-optical fields were mapped using a towed undulating vehicle, and horizontal velocity was measured with a shipboard...
During March–April 1999, 2 weeks of undulating CTD and shipboard acoustic
Doppler current profiler surveys revealed the variability of the intense internal tide on the
northern edge of Georges Bank. The nature of the internal tide was modulated by episodic
surface intrusions of cool, fresh Scotian Shelf Water (SSW), stratifying...
