Other ID: none

Status: Completed

Organization(s): USGS, Woods Hole Coastal and Marine Science Center

Funding Program(s):

Principal Investigator(s): John Crusius

Affiliate Investigator(s):

Information Specialist(s): Dirk Koopmans

Data Type(s): Environmental Data: Current, Environmental Data: Conductivity, Environmental Data: CTD, Environmental Data: Temperature, Geochemical: Surveys (geochemical), Environmental Data: Meteorology, Time Series: Mooring (physical oceanography)

Scientific Purpose/Goals: Measure submarine groundwater discharge in Salt Pond inlet using new eddy correlation approach. ADV and CT will be deployed together during night-time falling tides, while observations (temperature and salinity) of groundwater endmember will be made using a piezometer/peristaltic pump/CT sensor set-up.

Start Date: 2006-09-25

End Date: 2006-09-28

Equipment Used: Norteck ADV, Trident subsurface porewater conductivity probe, Piezometer, Temperature and salinity, Submersible pumps, Sensors - other mooring

Information to be Derived:

Summary of Activity and Data Gathered: 3 3-hr deployments were conducted during falling tides (ending at low tide). We collected continuous current, temperature and salinity data at a location 6 m from shore and ~5 cm above the subsurface of the 50 m-wide Salt Pond inlet channel, and made point measurements of the subsurface conditions during each deployment using a piezometer/peristaltic pump/CT sensor set-up.
