Thermal Plume Discharge Characterization: Oswego, New York
Ocean Surveys performed a detailed field investigation of the combined thermal discharge plume of Nine Mile Point Nuclear Station (NMPNS) on Lake Ontario in Oswego, New York. The data supported numerical modeling efforts as part of an environmental evaluation for a proposed capacity upgrade and also evaluated the effects of any future increase in ambient lake water temperature.
Instrument moorings were deployed to capture the temporal nature of the plume and ambient lake temperature, and to monitor lake currents in the vicinity of the discharges.
The thermal plume was mapped with vessel-mounted temperature sensors and vertical profilers on three consecutive days.
