We are studying carbon cycling and sediment accretion dynamics at two marshes in Gulf Shores, AL. One has a tidal restriction that has resulted in a freshened, flooded wetland and the other has natural hydrology. USGS is leading the soil coring and analyses.
Location
Two coastal wetland sites connected to Mobile Bay by the Gulf Intracoastal Waterway near Gulf Shores, Alabama (Oyster Bay Nature Preserve and Emmet O. and Vina Wenzel Wetland Preserve).
Summary
Six sediment cores were collected along transects at two study sites. Three cores were collected from the Oyster Bay Nature Preserve and three cores were collected from the Emmet O. and Vina Wenzel Wetland Preserve. Cores were sectioned in the laboratory for further analyses.
Info derived
Radioisotope dating of marsh sediment cores. Sediment carbon, nitrogen, and sulfur content and isotopic signatures.
