USGS Coastal and Marine Geology Program

Field Activity Details for field activity 2016-034-FA

Other ID: none

Status: Completed

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

Funding Program(s): Estuarine Processes, Hazards, and Ecosystems (LQ00G3S)

Principal Investigator(s): Neil Kamal Ganju

Affiliate Investigator(s):

Information Specialist(s): Steven Suttles

Data Type(s): Environmental Data: CTD, Environmental Data: Current, Location-Elevation: Navigation, Sampling: Chemistry, Time Series: Mooring (physical oceanography)

Scientific Purpose/Goals: Evaluate sediment dynamics and sediment fluxes in Grand Bay estuary system over tidal and seasonal timescales using long-term instrumented mooring deployments and tidal cycle surveys.


Start Port/Location: Pascagoula, MS

End Port/Location: Pascagoula, MS

Start Date: 2016-08-01

End Date: 2016-08-10

Equipment Used: CTD 19+ with OBS, PAR, DO, Chl, ADCP, Garmin GPS 76, Van Dorn bottle, Bottom platform

Information to be Derived: Currents, waves, suspended sediment concentrations (SSC), temperature, salinity, Dissolved Oxygen, Chla, and dissolved organic matter (fDom).

Summary of Activity and Data Gathered: Deploy time series moorings to collect pressure, currents, wave, and environmental data. Conduct CTD surveys to measure spatial patterns of physical parameters (temperature, conductivity, turbidity, and dissolved oxygen).Collect water samples for suspended sediment concentration and organic content analysis.
