Power-Plant-Related Estuarine Zooplankton Studies

Source

Increased emphasis is being placed on formulating a particular study design that will generate the greatest amount of relevant information for a particular problem. This is a case history of a study design as it evolved from one level of information to another, yielding both quantitative and biologically meaningful information.

In-plant studies examining the effects of entrainment on zooplankton and field studies examining zooplankton abundance, composition, and distribution in the Chesapeake Bay in the vicinity of Calvert Cliffs Nuclear Power Plant (Baltimore Gas and Electric Co.) have been conducted from 1974 to the present. The evolution of these studies, with particular emphasis on design and statistical treatment, is discussed. Entrainment study designs evolved from discrete sampling episodes at 4-h intervals over 24 h to a time-series sampling design in which sampling took place every 30 min over 24 and 48-h periods. The near-field study design and sampling methods have included replicated net tows, using 0.5-m nets, and replicated and nonreplicated pumped samples, using a high-speed centrifugal pump. The relative collecting characteristics of sampling methods are described; study designs and applicable data analysis techniques are evaluated with respect to their ability to detect plant effects within defined limits of personnel and budgetary constraints.
