Marine Eutrophication in Perspective


Book Description

Is ecological knowledge relevant to environmental policy and if so, to what extent and in what way? After a series of oxygen depletion events in coastal waters in the 1980s, North Sea states acted to reduce inputs of nitrogen and phosphorus to the North Sea. The book analyzes the role of scientists and scientific information, as well as civil servants, in the formulation and implementation of these decisions.




Ecological Studies in the Middle Reach of Chesapeake Bay


Book Description

The decision to build a nuclear power plant at Calvert Cliffs on the western shore of the Chesapeake Bay in southern Maryland resulted in a Iandmark legal decision (Calvert Cliffs Coordinating Committee vs Atomic Energy Commission) and began one ofthe mostintensive long-term studies ever carried out in an American estuarine system. In the pages that follow we describe the major results and findings from studies conducted over more than a decade by scientists from The Academy of Natural Seiences of Philadelphia (ANSP). These studies were designed to assess the potential effects that operation ofthe Calvert Cliffs Nuclear Power Plant (CCNPP) might have on the mid-portion of Chesapeake Bay. The approach taken was to study major biotic components of the system over an area and a time period sufficient to allow comparison of conditions between preoperational and operational periods within a sampling locality, and comparisons of conditions at reference sites with those at impact sites afterplant operations began. Elementschosen for detailed study included: species composition and production rates of major primary producers; water chemistry; zooplankton, benthos and finfish abundance and species composition; the abundance and growth rates of commercially important shellfish (clams, oysters and blue crabs); and the colonization sequences of invertebrates on artificial substrates.
