Sea level affecting marshes model and remotely sensed and geo-spatial datasets for a large area

Figures & data

Figure 1. A part of a classified image using remote sensing data acquired on 17 February 2008. Ten categories were derived.

Figure 2. The size of inland freshwater marsh through time as irregularly flooded marsh, transition salt marsh, tidal freshwater marsh, and regularly flooded marsh were recoded as any one of four categories.

Figure 3. The size of estuarine open water through time as irregularly flooded marsh, transition salt marsh, tidal freshwater marsh, and regularly flooded marsh were recoded as any one of four categories.

Figure 4. The size of estuarine open water through time as tidal flat, ocean beach, and estuarine beach were combined as tidal beach, ocean beach, or estuarine beach.

Figure 5. The size of open ocean through time as tidal flat, ocean beach, and estuarine beach were combined as tidal beach, ocean beach, or estuarine beach.
