Bi-weekly surveys of water properties at two marine stations ~1 and 6.6 Km from the estuary mouth at bottom depths of 8 and 48 meters. These surveys include water column CTD profiles of temperature, salinity, dissolved oxygen, chlorophyll fluorescence, and Turbidity (OBS). Profile data are accompanied by discrete water samples collected by a Niskin bottle at 10 m depth, these samples are analyzed for the concentrations of chlorophyll-a and pico and nano planktonic algae and non-photosynthetic bacteria
