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.
Ground oyster tissue and tin capsule
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.
