Modelling the dispersal of Calanus finmarchicus on the Newfoundland Shelf: implications for the analysis of population dynamics from a high frequency monitoring site
Abstract We investigated the drift of passive particles on the N ewfoundland S helf and western L abrador S ea using numerical simulations to assess the possible sources of plankton collected at a high frequency sampling site (S27; 47.55°N, 52.59°W) located near the coast of N ewfoundland, C anada....
