First annual release of the Maryland's Coastal Bays Report Card. These sensitive coastal lagoons received an overall grade of C+ for 2008. Scientists, the Maryland Coastal Bays Program, National Parks Service, state and local politicians, other dignitaries, and the general public gathered to hear the assessment which was based on water quality and other monitoring data and disseminated widely through various media. The Report Card was a collaboration between several entities, including the University of Maryland Center for Environmental Science, IAN, EcoCheck, and the Maryland Coastal Bays Program.

Laboratory drying oven. Oyster tissue samples are on the bottom shelf and dried at 60 degrees Celcius overnight or until thoroughly dry. Dessicant is on the middle shelf to remove any moisture.

Oysters deployed as biological indicators of nitrogen source were dried and then ground for stable nitrogen isotope analysis. Muscle tissue is on the left, gills are in the middle, and mantle tissues are on the right.
Ground oyster tissue
For stable isotope analysis, small subsamples of homogenously ground oyster tissues in the scintillation vial are placed in the tin capsule, held by the forceps.

Preparing a sediment core for sampling
Sediment core preparation
This sediment grab remains open when sent to the bottom and the release snaps shut the mouth for sediment collection.

Water sample preparation
Oyster biological indicators are deployed in mesh cages that will be suspended 0.5 meters above the bottom by the white buoys and anchored by the bricks.
