Organic Productivity of Inshore and Offshore Waters of Barbados; A Study of the Island Mass Effect
Sander F and Steven DM. 1973. Organic Productivity of Inshore and Offshore Waters of Barbados; A Study of the Island Mass Effect. Bulletin of Marine Science. 23(4):771-792
Repeated observations of primary and secondary production and related hydrographic and nutrient characteristics were made at inshore stations at Barbados from July 1968, to June 1970, for comparison with an offshore site. No evidence of regularly recurring variations of a seasonal nature was seen in the magnitudes of production and nutrient salts. Production showed progressive increase offshore to inshore consistent with an "island mass" effect. Diatoms were consistently the most prominent phytoplankton group inshore. Increased primary production near land was mainly exploited by copepods. Assimilation numbers, which were considerably higher inshore than offshore, suggest that carbon fixation per unit of chlorophyll was less efficient in oceanic water and were indicative, perhaps, of the respective physiological states of the plant populations.
