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): Meagan Eagle, Kevin Kroeger

Affiliate Investigator(s):

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

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

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: 2021-01-13

End Date: 2021-12-31

Equipment Used: YSI multiparameter sonde, YSI EXO2 Multi-parameter Sonde, Chambers for gas flux measurement, RTK, Piston corer, Creek moorings, Groundwater wells (PVC), Masterflex Portable Peristaltic Pump, LI-COR 7810 CH4 CO2 analyzer, ProOceanus mini CH4, Onset HOBO Weather Station, Onset HOBO Temperature Logger, InSitu BaroTroll 500, Eddy Co-Variance Flux Tower, In-Situ AquaTroll 200 (CTD), Push Point porewater samplers

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 and methane; creek measurements using a YSI multi-parameter sonde and ProOceanus mini-CH4. 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. Sediment core collections from new sites (Woods Hole, West Falmouth, Flat Pond) will be age-dated and analyzed for carbon content.

Summary of Activity and Data Gathered: Data and sample collection have been completed.
