Start Port/Location: Huntington Harbor, NY

End Port/Location: Patchogue, NY

Start Date: 2008-05-05

End Date: 2008-05-23

Equipment Used: GPS (wh), Resistivity Profiler, Piezometer, RAD7 radon detection instrument, Seepage meters, Submersible pumps, Digital camera

Information to be Derived:

Summary of Activity and Data Gathered: Collected resistivity data and geochemical samples to identify sites and rates of submarine groundwater discharge (SGD) to the coastal ocean. Data gathered included resistivity profiles, ground water and surface water geochemical data (temperature and salinity) and samples to be analyzed for nutrients, radioisotopes, and trace metals.

Staff: Sandy Baldwin, John Bratton, Michael Casso, VeeAnn Atnipp Cross, John Crusius, Laura Erban, Adrian Green, Kevin Kroeger, Carolyn Ruppel, Charles Worley
