Abstract : Eight hydrographic surveys were made in each of the bays, two each season, for the year 1960. In each bay eight stations were occupied for a 25 hour period commencing 1200 of the first date to 1200 of the second. Simultaneous hourly observations were made by 2 man crews, occupying skiffs or stationed on bridges, of water temperature, current direction and velocity, air temperature, wind direction and velocity, cloud cover, and state of the sea. In addition, water samples were taken for titration in the laboratory for chlorinity. Field titration for dissolved oxygen using the Winkler method was undertaken on a portion of each water sample. Current observations were made only at the surface and bottom of each station using weighed calibrated current crosses. All other observations were made at the surface, 5 feet, 10 feet, 20 feet, and bottom where depths permitted. Large gaps in the data represent extremely bad weather conditions when observations were impossible.
