This report provides an assessment of eutrophic conditions for 141 U.S. estuaries. The report was based on data and information provided by scientists and experts from around the country. Results from the assessment show that two-thirds of the estuaries evaluated exhibited moderate to high levels of eutrophication. Report production was a collaborative effort between Suzanne Bricker (NOAA NCCOS), EcoCheck (NOAA-UMCES Partnership) and IAN. More information is available from the NEEA website.

Monitoring water quality and determining nutrient inputs is essential to assess ecosystem health. Partnering with the Maryland Coastal Bays Program and the Department of Natural Resources, this study focused on four regions in Maryland's Coastal Bays. These regions, St Martins River, Public Landing, Johnson's Bay, and Chincoteague Island, were found to be nitrogen 'hotspots' by the 2004 water quality assessment study.

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 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 newsletter is based on research conducted by Dr Mark Luckenbach and a presentation he gave at the Chesapeake Bay Seminar Series in July 2003. The introduction of Crassostrea ariakensis into Chesapeake Bay has been proposed for both economic and ecological gain. Data exists suggesting that C. ariakensis grows significantly faster and is more resistant to the diseases that have devastated the native oyster.

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.

The abundance and productivity of benthic microalgae in coral reef sediments are poorly known compared with other, more conspicuous (e.g. coral zooxanthellae, macroalgae) primary producers of coral reef habitats.

An assessment of nitrogen sources to the Choptank and Patuxent River (including Island Creek), was conducted during the summer of 2003. Results demonstrated that both rivers were compromised with sewage derived nutrients. An Ecosystem Health Index for defined reporting regions was calculated from a variety of ecosystem heath parameters and then converted to a report card grade from A+ to D- and F for fail (Table 1).
