Field Activity 2009-021-FA

Identifier 2009-021-FA
Alternate names B-21-09-RI
Purpose Continuous resistivity profiling to map submarine fresh-saline groundwater interface in Greenwich Bay.
Location Greenwich Bay, Narragansett Bay, Rhode Island, United States, North America, North Atlantic;
Summary May 13, Weds., Worley arrives in PM to set up gear on boat at Norton's Marina, East Greenwich, RI; May 14, Thurs., Worley, Bratton, King, Miller survey with 50-m CRP streamer in Greenwich Cove, Apponaug Cove, around perimeter of Greenwich Bay, and several N-S crossings in western half, King put off at marina at noon, VeeAnn Cross checks AM data remotely back in Woods Hole -- looks OK; May 15, same crew (incl. King) survey open parts of Greenwich Bay with 100-m streamer, periodic salinity measurements with YSI 30 (all 25.5-27.8 ppt), run long W-E lines, then out mouth to Patience Island, then SW to mouth of Potowomut Cove, then N back to Greenwich Bay, zigzagging N-S-N over eastern half of bay, back at pier at 1530.

Description and usage history of this equipment

YSI multiparameter sonde
Conductivity, Dissolved Oxygen, ORP, pH, Temperature
1
The YSI 30 is a handheld system. The unit was placed in the water and measurements taken at 10 locations in Greenwich Bay. The measurements are surface water temperature, salinity, and specific conductance measurements. The specific conductance measurements were temperature-compensated.
