The fish schools appear as clear holes in this image. These plots are drawn when surface is selected, with the buttons allowing toggling between the three environmental variables measured continuously at the surface. Results after algorithms for fish and plankton location for all transect A passes in the 1995 survey. Plankton are shown by red rectangles and fish shoals with blue rectangles. The bottom is shown on the transects as well.
Plankton are clearly higher in the water column at night and are near the bottom during the daytime.
Fish shoals tend to be larger at night. There are several larger fish shoals identified during the daytime near the bottom along this transect, mostly in the inner shelf and front regions.
