Scotian Shelf. Primary Production. Figure 6 shows the sharp boundary zone separating coastal water and warmer slope water charac-... 

Figure 6. Scotian Shelf and slope-water region. The mean position of a thermal front with surface temperatures of -- 9-11 °C was contoured from satellite imagery and partly from Batfish profiling. The work area for Batfish transects is shown along 63°25 W (10).

Figure 7. Contoured profiles of temperature (A), salinity (B), density (C), and chlorophyll a (D) on depth (10-100 m) between 42°30 N and 43°00 N on the Scotian Shelf. Increased shading indicates concentrations ranging from 1 to 5 mg/m (10).

Additional calculations (10) indicated that the movements of the intrusions produced localized turbulent mixing ascribed to shear instabilities. These mixing events, driven by the M2 internal tides, caused a potentially efficient mechanism for vertical transport of heat and salt as input to the Scotian Shelf. These vertical-mixing events, which continually replenish nutrients (e.g., nitrates, nitrites, silicates, and inorganic phosphates) from slope waters below, can explain the anomalously high productivity occurring at the front. 

Zooplankton. Studies of the outer edge and shelf-break region of the Scotian Shelf were also extended to the vertical and horizontal distributions of zooplankton. The most intriguing feature of these vertical profiles was the consistent location of copepods above the subsurface chlorophyll... 

Figure 10. Vertical Batfish profiles taken from the transect of Figure 6 on the Scotian Shelf. The profiles are separated into the following components chlorophyll, production estimated in two Ways from a chlorophyll/ light model, small copepods (S.C.), and all stages of C. finmarchicus (13).

Figure 11. The depth of maximum chlorophyll, production relative to small copepods, and C. finmarchicus. The tow began in coastal waters of the Scotian Shelf (left side of plot) and the course was reversed at the front. There are -- 90 vertical Batfish profiles in the transect (13).
