Groundwater sampling on Fire Island and beneath nearshore areas in Great South Bay.
Location
Great South Bay, Fire Island, Long Island, New York, United States, North America, North Atlantic;
Summary
In spite of weather and island-related logistical challenges, the team was able to sample 10 existing wells and approximately 10 piezometer profiles at two transect sites in Kismet and Watch Hill, collect approximately 20 groundwater samples from distributed piezometer sites along the shore of Great South Bay, and make seepage meter measurements over two days at each of the transect sites. Approximately 130 groundwater samples for some or all of the following parameters or analyses were collected from most sampling sites: temperature, pH, salinity, specific conductance, dissolved oxygen in mg per liter and percent saturation, oxidation-reduction potential, dissolved gases (methane, nitrous oxide, radon), DOC/DIC, nutrients (nitrate, nitrite, ammonium, phosphate), metals, MIMS N2-Ar, nitrogen species isotopes, and pharmaceuticals. A time series of radon in water, salinity, temperature, and tidal stage data was also collected from a moored raft at the Watch Hill piezometer transect site. These data will complement previous data from Patchogue and from electrical resistivity surveys in the bay.
