USGS Coastal and Marine Geology Program

Field Activity Details for field activity 2000-074-FA

Other ID: IB P-74-00-MY

Status: Completed

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

Funding Program(s):

Principal Investigator(s): Michael Bothner

Affiliate Investigator(s): William Martin, WHOI

Information Specialist(s): PARTNER

Data Type(s): Geochemical: Experiments, Imagery: Photo, Location-Elevation: Navigation

Scientific Purpose/Goals: Deploy two benthic chambers ("squirts") near the long-term Station 3. The purpose is to measure the flux of metals and nutrients from sediments. Discharge of sewage effluent from the Massachusetts Bay outfall began on September 6.


Start Port/Location: Boston, MA

End Port/Location: Boston, MA

Start Date: 2000-09-22

End Date: 2000-09-22

Equipment Used: DGPS, Benthic Chambers, Digital camera

Information to be Derived:

Summary of Activity and Data Gathered: Each pair of divers deployed one benthic chamber in one dive. The chambers were lowered in a weighted frame and divers lifted the chambers out of the frame and placed them on the bottom nearby. Visibility was poor.
