Salt marshes and the role these ecosystems play in local-to-global carbon budgets are an important factor in how these ecosystems play a part in the overall carbon budget. The generation and integration of how tidal channel migration processes affect marsh ecology and carbon storage is important in understanding how marshes change over time. This research evaluated ecosystem function by characterizing plant and animal communities, soil pore water chemistry, soil carbon storage, and vertical accretion rates in three marshes impacted by channel migration. Samples collected from wetland bands that formed in the salt marshes located at Doboy Sound, GA. Radioisotope activity (210Pb, 137Cs) of sediment cores were measured to determine soil composition. Soils were analyzed for total organic carbon content and composition (δ13C) for analysis of different turnover times. Data analysis has shown that the retreating marsh is the most impacted by tidal channel migration compared to the prograding marsh.
