A. Profiles and Plankton: Sampling Day
METHODS
Sampling was conducted on a semimonthly basis at stations representing both Gunston
Cove and the Potomac mainstem (Figure 1). One station was located at the center of Gunston
Cove (Station 7) and the second was placed in the mainstem tidal Potomac channel off the
Belvoir Peninsula just north of the mouth of Gunston Cove (Station 9). Dates for sampling as
well as weather conditions on sampling dates and immediately preceding days are shown in
Table 1.
