Fig. 4.3. a,b Contrast between widely opened adjacent basin with surface outflow and intennediate water inflow (e.g., Gulf of California, cf. Fig. 4.5), and
basin with horizontally separated inflow and outflow
of surface water (e.g., Caribbean Sea). c NorwegianGreenland Sea with simplified surface current pattern
and bottom currents in the neighborhood of the
Greenland-Iceland-Scotland Ridge. Note special sites
of bottom water overflow and associated huge sediment drift bodies to the south of the ridge. Asymmetrie sediment distribution is briefly discussed in text.
