An Analysis of Phytoplankton, Microzooplankton and Mesozooplankton Populations in the Vicinity of the C. P. Crane Generating Station During the Spring Months of 1979

摘要

Sampling of spring 1979 plankton populations at the C.P. Crane Power Station was conducted at 15 stations during six sampling periods for phytoplankton, at 5 stations monthly from March to June for microzooplankton and monthly at 14 stations for mesozooplankton. Ancillary physical data were collected at all the above stations, while nutrients were measured twice in April. The spring 1979 physical conditions included uniformly low salinity, seasonally rising temperatures, gradually decreasing oxygen levels, and water transparency increasing from very low early spring levels. Nutrient measurements, made only in April, showed uniformly low ammonia, no nitrite, relatively high nitrate, moderate to moderately high phosphate and very high silicon.
