Control of the phytoplankton distribution in the Strait of Gibraltar by wind and fortnightly tides
CTD-fluorescence-turbidity profiles from two surveys conducted in June and September 1997 were examined in order to evaluate the influence of the predictable fortnightly (spring/neap) tidal cycle and the less predictable wind on the phytoplankton distribution in the Strait of Gibraltar. The injectio...
