This is a comprehensive course designed to provide students with a broad perspective on the subject of environmental health issues pertinent to the Chesapeake Bay. It will provide a historical context, a description of the major stressors impacting the Bay and the current health of the Bay and it's organisms. We will investigate some of the reasons for it's current state of health and provide numerous case study examples documenting the major issues concerning the health of the Bay and it's resident organisms. Many of the case studies will discuss the major species in the Bay (e.g. oysters, blue crabs, fish) and be presented by local leading experts in the specific topics. In addition, concepts and examples will be discussed in a broader perspective with reference to other estuarine systems.
