“…Other sources of nutrients are less well described; the nutrient load from stream input is unknown because most streams enter the bay through an estuary system that acts as a buffer zone, trapping most of the carbon and nutrients before they can enter the ocean ecosystem (Laws et al, 1999). Previous studies have addressed the environmental impacts of the sewage plumes entering Mamala Bay, and they found that nutrient concentrations and particle loads were higher inside the plume, and that phytoplankton growth was stimulated under physical forcing conditions where the time scale of dilution was longer than the phytoplankton growth response (Petrenko et al, 1997). Other studies have also found significant chlorophyll a increases downcurrent of the sewage treatment plants (Laws et al,FIGURE 7.…”

“…Seasonal variations in inputs from storm overflows were identified, as were failed CSOs and cross-connected sewers. Field-based fluorescence has also been used to investigate the effect of marine sewage plumes on the biology, optical character and particle-size distribution of coastal waters around an outfall diffuser using peak T fluorescence to track the extent of the plume (Petrenko et al, 1997).…”

“…It is possible, using simple equipment, to target a single excitation and emission wavelength pair, diagnostic of a specific molecule (Skoog et al, 1996;Petrenko et al, 1997;Determann et al, 1998;Chen, 1999;Thoss et al, 2000;Clark et al, 2002;Nagao et al, 2003;Del Vecchio and Blough, 2004a) which is useful in determining the presence or absence and character of a target compound. However, the technique is relatively slow and inflexible, particularly if a range of excitation and emission wavelength scans are required for the study of more than one fluorophore.…”

Dissolved organic matter (DOM) in aquatic systems originates from a range of sources. Some is allochthonous, transported from the surrounding landscape to the water body, and is derived from and influenced by the geology, land use and hydrology of its origin. Some is created in situ through microbial activity, which may provide an independent source of organic matter, or a recycling mechanism for that which has been transported into the water body. The relative contribution of each source depends upon the location and environmental conditions within and without the water body. Human activity is also a source of DOM, much of which is believed to be labile, which can enter the aquatic system through direct point discharges, diffuse leaching and aerial dispersal. Fluorescence spectroscopy can provide an excellent tool to source DOM fractions, and to monitor and understand DOM transformations in aquatic systems, as much DOM has an intrinsic fluorescence. In particular, recent advances in optical technology, enabling rapid investigation of shorter wavelengths, have enabled more detailed characterization of organic material and its reactions in water. In this article, we review the use of fluorescence spectroscopic techniques to measure the intrinsic fluorescence of organic matter and the application of fluorescent DOM analysis in marine waters, freshwaters and wastewaters.

“…These authors used chlorophyll fluorescence, a beam transmissometer, a current meter, and a CTD collectively to determine plume location. The work of Petrenko et al (1997) complimented these findings by utilizing only elevated levels of fluorescence to detect plume waters through the use of a fluorometer with an excitation/emission (Ex/ Em) wavelength pair of 228/340 nm. They concluded that such fluorescence (low Ex/Em wavelength) may be useful as a new in situ natural tracer of effluent discharges.…”

A monitoring mission to map and characterize the Point Loma Ocean Outfall (PLOO) wastewater plume using an Autonomous Underwater Vehicle (AUV) was performed on 3 March 2011. The mobility of an AUV provides a significant advantage in surveying discharge plumes over traditional cast-based methods, and when combined with optical and oceanographic sensors, provides a capability for both detecting plumes and assessing their mixing in the near and far-fields. Unique to this study is the measurement of Colored Dissolved Organic Matter (CDOM) in the discharge plume and its application for quantitative estimates of the plume's dilution. AUV mission planning methodologies for discharge plume sampling, plume characterization using onboard optical sensors, and comparison of observational data to model results are presented. The results suggest that even under variable oceanic conditions, properly planned missions for AUVs equipped with an optical CDOM sensor in addition to traditional oceanographic sensors, can accurately characterize and track ocean outfall plumes at higher resolutions than cast-based techniques.
