A Mid-Chesapeake Bay Marshlands Restoration project is being developed by the Integration and Application Network, the US Army Corps of Engineers, Maryland Port Administration, US Fish & Wildlife Service, and Maryland Department of Natural Resources. This newsletter discusses the ecological, economic, and engineering issues associated with using dredged material to restore the eroding marshes of the mid-Chesapeake Bay.

This is a practical handbook on how to communicate science effectively. The first part is an introduction to the principles of science communication – what effective science communication is, why it is important, and how to do it. The principles in these chapters include how effective science communication can change societal paradigms and make one a better scientist.

This newsletter is the product of the Conceptual Ecological Model workshop, held in Louisiana in November, 2005. Coastal Louisiana is home to the nation’s largest port complex in both tonnage and infrastructure, and produces or transports nearly one-third of the nation’s oil and gas supply.

Environmental models are essential for simulating ecosystems that are either too large or too complex to isolate to conduct real world experiments. Models allow scientists to simulate changes in an ecosystem due to changes in population, land use, or pollution management.

This data report details the results of an intensive sampling effort by the Integration and Application Network in the Maryland Coastal Bays. A spatially explicit Water Quality Index was developed from standard water quality analyses and a relatively new stable isotope technique.

This report summarizes monitoring data collected over the past several years for water quality, aquatic living resources, and habitat categories. It utilizes conceptual diagrams for each reporting region to highlight the key ecosystem processes, biota and estuarine health problems.

This newsletter is based on the 'Status of nutrients in Delmarva soils, groundwaters, creeks and tributaries forum', October 21, 2003. Extensive poultry operations and associated feed grain production on the Delmarva Peninsula have resulted in elevated nutrient levels in soils, groundwater, creeks and tributaries of the Chesapeake Bay.

This poster details the importance of developing a scientifically rigorous, spatially explicit ecosystem health report card on Chesapeake Bay and its watershed to facilitate coordination and feedback between monitoring, management and research. A pilot study was conducted in July 2003 on the Patuxent and Choptank Rivers using a novel stable isotope technique (see "Assessing Nutrient Sources" newsletter below) together with more traditional water quality monitoring techniques.

Management of coastal systems is becoming increasingly important, however understanding the process of effective management often remains elusive. This chapter contrasts examples of environmental problems and associated management in Moreton Bay, Australia, and Chesapeake Bay, USA. Targeted research in Moreton Bay identified specific issues which led to changed practices, while intense management and research in Chesapeake Bay has been unable to keep pace with increasing anthropogenic stress.
