Direct Observations of Along-Isopycnal Upwelling and Diapycnal Velocity at a Shelfbreak Front

Barth, John A.; Hebert, Dave; Dale, Andrew C.; Ullman, David S. (American Meteorological Society, 2004-03)

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 t ...
The front on the northern flank of Georges Bank in spring : 1. tidal and subtidal variability

Dale, Andrew C.; Ullman, David S.; Barth, John A.; Hebert, Dave (American Geophysical Union, 2003)

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 i ...
The front on the Northern Flank of Georges Bank in spring : 2. Cross-frontal fluxes and mixing

Ullman, David S.; Dale, Andrew C.; Hebert, Dave; Barth, John A. (American Geophysical Union, 2003)

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 ...
