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.

Some cages became very fouled with algae and bryozoans during deployment while others did not. These two cages were deployed at the same location during the same time period.
Fouling of cages for oyster biological indicators
Cages for oyster biological indicators are messy with sediment and fouling after deployment
