View new CMGDS report form

Other ID: none

Status: Pending

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

Funding Program(s): Biogeochemistry, groundwater monitoring, and environmental assessment (LQ000I4)

Principal Investigator(s): Kevin Kroeger, Meagan Eagle

Affiliate Investigator(s):

Information Specialist(s): Meagan Eagle, Rebecca Sanders-Demott, Jennifer O'keefe Suttles, Adrian Mann, Thomas Brooks

Data Type(s): Environmental Data: CTD, Location-Elevation: Transects, Geochemical: Experiments (geochemical), Biological Field Study: Experiments (biological), Time Series: Geochemical Monitoring, Sampling: Chemistry, Environmental Data: Methane, Environmental Data: CO2

Scientific Purpose/Goals: Continuous monitoring of surface water and pore-water depth, salinity, and temperature, soil temperature and meteorological data, and pore-water collection for chemistry analysis in estuaries across Cape Cod, MA to examine environmental geochemistry and the impact of impoundments and restoration of salt marsh environments.


Start Port/Location: Woods Hole, MA

End Port/Location: Woods Hole, MA

Start Date: 2020-04-01

End Date: 2020-11-10

Equipment Used: RTK, Masterflex Portable Peristaltic Pump, Groundwater wells (PVC), LI-COR 7810 CH4 CO2 analyzer, Chambers for gas flux measurement, Onset HOBO Temperature Logger, Onset HOBO Weather Station, InSitu BaroTroll 500, Eddy Co-Variance Flux Tower, Push Point porewater samplers, In-Situ AquaTroll 200 (CTD)

Information to be Derived: Time-series sensor data including eddy co-variance flux tower measurements of methane and carbon dioxide; meteorological measurements; soil temperature; well measurements of CTD. Discrete measurements of CO2 and CH4 flux from different wetland vegetation sites will correspond with pore-water collections for chemical constituents (including DOC,DIC, Alkalinity, Chloride, Sulfate) and multi-parameter YSI measurements.

Summary of Activity and Data Gathered: Completed sediment, porewater and gas flux analyses.
