Summer 2003: Indian River Lagoon environmental monitoring and observations of cysts of dinoflagellates.  G.D. DELFOSSE (1), G.A. MAUL (1), and S.L. MORTON (2).  (1) Dept. of Marine and Environmental Systems, Florida Institute of Technology, Melbourne, FL  32901, (2) NOAA/NOS, Charleston, SC 29412. During the summer of 2003, sixty-three Indian River Lagoon stations were sampled from Titusville to West Palm Beach.  Observations from the IRL include DO, temperature, salinity, Secchi depth and Ule-scale color.  Sediments were collected and shipped to the NOAA Hollings Marine Laboratory for the analysis of cysts of Pfiesteria-like organisms (PLOs).  The IRL dissolved oxygen concentrations were between 8 and 10 mg/l (120 and 150% saturation). The temperature on average was 28-29°C, somewhat higher than normal. Salinity was higher than previous summers, averaging 29 psu. The Ule-scale values averaged around 7, which is typical of brown-green IRL waters.  PLOs were identified at 16 of 63 stations.
