Fig. 1. Map of the Maine coast identifying the four coastal compartments as delineated by Kelley (1987) with an arrow identifying the location of Taunton Bay within the IslandBay Complex. The inset map illustrates the location of the Maine coast within the Gulf of Maine Bight.
Fig. 2. Subaqueous landform map for Taunton Bay, Maine. The map shows seven landscape units as identified by Flannagan and Osher (2006). The locations of soil profiles studied for this research are identified by points and labeled with profile number.
Fig. 3. Organic C concentrations for soil horizons from all profiles from each of the six profile groups: (a) recently submerged edges and coves, (b) submerged fluvial streams and marshes, (c) deep edge soils, (d) bay bottom, (e) mussel shoal, and (f) channel shoulder. Individual points represent the midpoint of each soil horizon.
Fig. 4. Bulk density for soil horizons from all profiles from each of the six soil profile groups: (a) recently submerged edges and coves, (b) submerged fluvial streams and marshes, (c) deep edge soils, (d) bay bottom, (e) mussel shoal, and (f) channel shoulder. individual points represent the midpoint of each soil horizon.
