Samples are ground with mortar and pestle
Grinding with mortar and pestle
Collecting plankton along the Patuxent River
Plankton collection
Water samples from the Patuxent River are prepared for analysis on board the R/V Aquarius

Oysters in bags hang off the side of the Horn Point Laboratory dock on the Choptank River on the Chesapeake Bay
Sitting off the dock on the Bay
The eastern oyster (Crassostrea virginica) builds reefs as oyster larvae set onto other oyster shells, as seen in this small clump of at least four oysters.

The oysters in this cage are being deployed as biological indicators of nitrogen source. They will be suspended 0.5 meters above the bottom by the white buoy.
Oyster biological indicators
A sediment core has been collected and is being prepared for storage and analysis by carefully filling the core with water from the sample site to minimize disturbance.

Water sample analysis
Tim Carruthers prepares a sediment corer with a rubber stopper. This corer is made by cutting off the top of a 60 mL syringe. Samples were collected from Maryland's Coastal Bays
Collecting sediment cores
Sediment slurries in triplicate were mixed and flasks were capped to trap gases released during denitrification

An old mass spectrometer for analyzing stable isotopes
Isotope ratio mass spectrometer
Water samples collected for analysis. These samples have been capped and crimped to seal against gas exchange so that dissolved gases can be analyzed.
