USGS Coastal and Marine Geology Program

Coastal & Marine Geology Program

Field Activity Details for field activity 2012-015-FA

Other ID: UML-0612

Status: Completed

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

Funding Program(s):

Location: Upper Mystic Lake, Arlington, MA, United States

Principal Investigator(s): John Pohlman

Affiliate Investigator(s): Ruben Juanes and Ben Scandella, MIT

Information Specialist(s): Michael Casso

Data Type(s): Environmental Data: Methane, Imagery: Photo, Location-Elevation: Navigation, Sonar: Single Beam

Scientific Purpose/Goals: Collect methane, CO2 and meteorological data from Upper Mystic Lake to calculate air-sea methane and CO2 fluxes. Data will be acquired with the greenhouse gas flux analyzer aboard the Carolina Skiff.

Vehicle(s):

Start Date: 2012-06-04

Start Port/Location: Upper Mystic Lake Dock

End Date: 2012-06-07

End Port/Location: Upper Mystic Lake Dock

Equipment Used: Cavity Ring-Down Spectroscopy (CRDS), Digital camera, Humminbird fishfinder, GPS (wh), HYPACK

Information to be Derived: Samples and chemical analysis;

Summary of Activity and Data Gathered: CRDS data on surface water methane and carbon dioxide concentrations were collected along 10+ kilometers of survey lines in the Upper Mystic Lake. Additionally, surface air methane and CO2 were measured at the end of each survey line and along a continuous transect that crossed the lake at several points and within the fore boat basin. Humminbird sonar data collected along the survey lines. Discrete samples for methane concentration analysis were collected at several locations and within the fore boat basin.
