Monthly surveys of water properties along the Alexander micro-estuary
Monthly surveys of water properties along the estuary. These surveys include water column CTD profiles of temperature, salinity, dissolved oxygen, chlorophyll fluorescence, and turbidity (OBS). Profile data are accompanied by Secchi depth measurements and discrete water samples collected by a horizontal Niskin bottle near the surface and near the bottom. Water samples are analyzed for the concentrations of Phosphate, Nitrate, Nitrite, Ammonium, Total and particulate nitrogen and phosphorus, total suspended solids, particulate organic matter, biological oxygen demand, chlorophyll-a, cell counts of nano and pico planktonic algae and non-photosynthetic bacteria.
