Calipers
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.

Samples are ground with mortar and pestle
Grinding with mortar and pestle
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.

Oyster shells are cleaned and dried in preparation for larval settling as part of the Oyster Restoration Project and the Horn Point Laboratory oyster hatchery.
Oyster shells for restoration
Oyster shells are cleaned and dried in preparation for setting oyster larvae for restoration, as part of the Oyster Restoration Project in conjunction with the Horn Point Laboratory oyster hatchery.

The 2008 Severn River Report Card Release. The report card summarizes 2008 water quality results, which are based on data collected by the Severn Riverkeeper Program. This report card helps to clarify the Severn's health, and provides instructions on what individuals can do to improve its condition. The release of this report card was attended by local, state, and federal representatives, Severn River Keepers, and IAN staff.

As part of the Science Communication course, students design the layout for a newsletter. Students decide where to include text, photos, figures, maps, conceptual diagrams. Each section in encapsulated with an active title for effective communication.

Nutria (Myocaster coypus) are an introduced semi-aquatic rodent species originally brought to Maryland for fur in the 1940s, but are since considered to be nuisance species, destroying large areas of marshland, particularly around the Blackwater National Wildlife Refuge.
