determine the effects on marine fauna and flora (Figure I) A chemical and physical analysis was run on water samples collected at stations in the area. Procedures: Surface water samples were collected by submerging a collecting bottle in water by hand over side of the boat. Subsurface water samples were collected by means of the Nansen reversing water bottle. Surface temperatures were recorded at the time the surface water samples were collected. Bottom temperatures were taken with a reversing thermometer attached to the Nansen bottle at the time the bottom water samples were collected. All the water samples were subjected to chemical and physical tests to determine, the conditions that exist in the bay during this time. Turbidity was determined by the Lumetron Colorimeter and the pH was checked with the Beckman pH meter. The dissolved oxygen concentration of the bay water was determined by the Unmodified Winkler Method. All water samples were titrated with silver nitrate to determine the salinity. Data were collected in conjunction with Job No. A-2, B-2, and C-2. Hydrographic and climatological data collected at the Seabrook Field Laboratory were also used in conjunction with this report
