Why Does Vertical
Distribution Matter?
§Vertical distribution
determines transport
trajectories on the Bank: copepods in the surface waters (0- 15 m) are advected by Eckman
transport.
§Copepods below the Eckman
layer are less
subject to transport. The tidal mixing front may help retain
deeper-dwelling
copepods on the Bank.
§Remaining deeper in the water
column may
represent a strategy to aid retention and avoid loss from Georges Bank for small copepods like Pseudocalanus spp.
Chen
et al. (2003) modeled particle transport on Georges Bank, showing distributions
of particles at model days 16.5, 18.5, and 19.7 for the case with tidal forcing
plus realistic wind stress.
