The USGS in cooperation with LSU and the GBNERR will collect sediment cores and penetrometer measurements from marshes in Middle Bay and Point Aux Chenes.
Location
Grand Bay National Estuarine Research Reserve
Summary
At Site 8, three sediment cores (peat augers 0.5-2 meters in length and/or push cores < 1 meter in length) will be collected on the marsh platform at roughly 10, 20, and 50 meters from the shoreline. Push cores will be retained for sediment analysis.
Marsh shear strength measurements will be collected using a penetrometer at seven sites (Sites 1,3,5-9). The penetrometer will be pushed into the marsh surface and measurements will be taken. No samples will be retained from the penetrometer.
