Funding Program(s):

Principal Investigator(s): Kevin Kroeger

Affiliate Investigator(s):

Information Specialist(s): Sandy Baldwin, Thomas Brooks, Adrian Green

Data Type(s): Location-Elevation: Navigation, Environmental Data: CTD, Environmental Data: Meteorology, Environmental Data: Temperature, Time Series: Mooring (physical oceanography), Environmental Data: Methane, Environmental Data: Radon, Environmental Data: CO2, Environmental Data: Dissolved Oxygen, Environmental Data: Current

Scientific Purpose/Goals: To quantify the geochemical components, greenhouse gas fluxes and carbon storage in a tidal marsh system in three study sites, Sage Lot Pond, Hamblin Pond and Great Pond, Waquoit Bay and East Falmouth, Ma.


Start Port/Location: Sage Lot Pond

End Port/Location: Sage Lot Pond

Start Date: 2013-06-10

End Date: 2013-08-30

Equipment Used: GPS (wh), Sensors - other mooring, Current, Pressure, Temperature and salinity, Turbidity, Cavity Ring-Down Spectroscopy (CRDS), RAD7 radon detection instrument, Sensor - CO2, O2 sensor, ADCP

Information to be Derived: Time series data;Samples and chemical analysis;Suspended sediment concentrations;Laboratory sensor data;

Summary of Activity and Data Gathered: Continuous measurements of greenhouse gas fluxes, and discrete water sample collection over a complete tidal cycle in 3 estuarine creeks once per month. Time series data from deployed water quality sensors and ADCP. Total of 9 sampling events over this period.
