Kathryn Smith with the EMRG project are collecting net sediment tiles (NST), shoreline positions, and retrieving sensors (4 AquaTrolls, 4 RBRs, 4 RuggedTrolls, 1 BaroTroll; combined value ~$30,000) measuring wave height, turbidity, and water level data with Grand Bay National Estuarine Research Reserve (GBNERR). Plan is to use GBNERR staff and vessel. Mississippi state university will provide assistance with sensor retrieval and downloading.
The study will evaluate the impact of a living shoreline on shoreline erosion and sediment transport. NST were deployed in Nov 2021 and were collected and redeployed quarterly until this trip (Jan 2023). This is a continuation of 2020-301-FA (prior to the installation of a living shoreline), 2021-320-FA (first couple of data sets collected following installation), and 2022-302-FA (post-reef continuation of NST and sensor deployments and collections). See notes for additional information on past trips.
This trip will be alternate field activity number (FAN) 23CCT01. This trip will be the final NST and sensor retrieval. All USGS-SPCMSC scientific gear will be removed from GBNERR at the conclusion of this trip.
Location
Grand Bay National Estuarine Research Reserve, Mississippi, United States, Gulf of Mexico
Info derived
Grain size, sediment deposition, shoreline positions and elevations, bulk density, loss on ignition, micro-fossils, turbidity.

The study will evaluate the impact of a living shoreline on shoreline erosion and sediment transport. NST were deployed in Nov 2021 and were collected and redeployed quarterly until this trip (Jan 2023).
This is a continuation of 2020-301-FA (prior to the installation of a living shoreline), 2021-320-FA (first couple of data sets collected following installation), and 2022-302-FA (post-reef continuation of NST and sensor deployments and collections). Previous alternate fans for 2022-302-FA include:
22CCT01 (Feb 13-17, 2022) - Retrieve and redeploy net sediment tiles and well sensors. Deploy platforms with sensors. Collect elevation and positional data for marsh features. Coordination with MSU for training.
22CCT02 (March 29-April 2, 2022) - Retrieve and redeploy platforms with sensors. Coordination with MSU for sensor training.
22CCT03 (May 2-6, 2022) - Retrieve and redeploy net sediment tiles and well sensors. Retrieve and redeploy platforms with oceanographic sensors. Collect elevation and positional data for marsh features. Coordination with MSU for sensor training.
22CCT04 (June 21-24, 2022) - Retrieve and redeploy platforms with oceanographic sensors.
22CCT05 (Aug 8-11, 2022) - Retrieve and redeploy net sediment tiles and well sensors. Retrieve and redeploy platforms with oceanographic sensors. Collect elevation and positional data for marsh features. USGS summer interns will assist with this trip.
22CCT06 (Sept 19-21, 2022) - Retrieve and redeploy platforms with oceanographic sensors.
22CCT07 (Nov 7-9, 2022) - Retrieve and redeploy net sediment tiles and well sensors. Retrieve and redeploy platforms with oceanographic sensors. Collect elevation and positional data for marsh features.
22CCT08 (Dec 12-14, 2022) - GBNERR and MSU staff will retrieve and redeploy platforms with oceanographic sensors.
