| Abstract |
Concentrations of ammonia, nitrate plus nitrite, phosphate, and silicate measured in microcosms at weekly intervals during one full year of operation are compared with concurrent data from adjacent Narragansett Bay and with data from a year-long survey of the bay taken in 1972-1973. The major features of the annual cycles for each nutrient in the bay were reflected in observations from nine microcosm tanks. This indicates that the forces driving the cycles in the bay must have counter-parts in the microcosms and that the general features of chemical cycling were similar. |
