Diel Movements of Juvenile Illex illecebrosus and Other Cephalopods in the Shelf Water-Slope Water Frontal Zone off the Scotian Shelf in Spring
Vertical water structure at two diel stations in the Shelf Water-Slope Water frontal zone seaward of the Scotian Shelf could be classified into five layers on the basis of some rather specific hydrographic characteristics. The near-surface layer (0-30 m) consisted of Shelf Water of low temperature a...
