Rapid Delineation of the Mean Plume Intensity Pattern from the Sediment Temperatures Underlying a Thermal Discharge
Abstract:The heat conduction process in the bottom sediments tends to generate a vertical temperature distribution which is increasingly smoothed in time as one penetrates into deeper layers. Thermal outfall areas generate a hot plume, which is often variable both in location and intensity. Thus, one would expect that bottom-sediment temperatures would yield more reliable estimates of sustained thermal stress on benthic communities than instantaneous observations in the water column. Experimental evidence has been obtained to support this hypothesis, and it is suggested that intermittent measurements of sedimentary temperatures may provide a more economical means of determining the thermal stress on benthic biological communities than continuous temperature recording.
