Spatial patterns in planktonic cnidarian distribution in the western boundary current system of the tropical South Atlantic Ocean
Abstract In marine western boundary systems, strong currents flowing coastward spread oceanic water masses over the continental shelves. Here we propose to test the hypothesis according to which oceanic cnidarian species may dominate western boundary system regions even in coastal waters. For that p...
