Abstract:
In October 2006, a cruise of the Florida Area Coastal Environment (FACE) program was conducted aboard the NOAA RV Nancy Foster. The cruise visited coastal sites in the vicinity of six treated wastewater boils in south Florida. The outfalls included in this study were those for the South Central (SC), Boca Raton (BC), Broward (BR), Hollywood (HW), Miami-Dade North (MN), and Miami-Dade Central (MC) wastewater treatment plants. The outfall terminus locations were determined by the ship's multi-beam instrumentation. The boils and associated down-current plumes were studied to produce a data set of ocean currents, ocean chemistry, and microbiology. Seawater was analyzed for Nitrate + Nitrite-N (N+N), Nitrite-N (NO₂), Ammonia-N (NH₄), Orthophosphate-P (P), and Silica (Si). Samples were collected by a conductivity-temperature-depth (CTD) rosette at three depths - near-surface, mid-depth, and near-bottom - and from three transects - inshore of the boil, approximately in line with the boil, and further offshore of the boil. The CTD data indicated a tendency toward better defined and deeper thermoclines at the 20-30 m depth in the deeper (more offshore) casts. The thermocline showed a tendency to shoal at 10-20 m and become less well defined in more inshore casts. Overall, surface samples showed the highest nutrient concentrations versus samples taken at other depths; surface samples taken nearest the boil showed the highest nutrient concentrations in comparison to other samples collected in the vicinity of the outfall. The only exception was Si, which had a maximum observed concentration at an inlet sampling site"--Executive Summary.
