Abstract

Field surveys of phytoplankton metabolism, based on oxygen changes, were made in Narragansett Bay from 1971-73. Annual daytime net production varied from 218 g C per m2 per yr in the East Passage to 429 g C per m2 per yr in the Providence River. The area based average for the bay was 269 g C per m2 per yr. The area based average night respiration was 159 g C per m2 per yr resulting in an annual net carbon available for export or to the benthos of 110 g C per m2 per yr. A set of microcosms, operated so as to simulate the Bay, had an annual net production of 276 g C per m2 per yr and a night respiration of 163 g C per m2 per yr resulting in an annual net carbon available for export or to the benthos of 113 g C per m2 per yr. *** DIRECT SUPPORT *** A01BY015 00002 © 1981 Estuarine Research Federation.
