Initial wetland characterization efforts relied on evaluation of historic maps and photographs, and field observations to document:
Wetland characteristics and recent history:
- Used historic topographic charts and aerial photos from 1875 to the present to document shoreline configuration, wetland distribution, and surface alterations.
- Characterized mangrove vegetation as to species composition, tree density, size, and health.
Surface and groundwater salinities:
- Characterized surface water salinity with standard conductivity meters, and inferred subsurface conductivities from readings of bulk ground conductivities in the top 7.5-15 meters.
Wetland fishes:
- Sampled small fishes with beach seines and wire minnow traps in wetland ponds and tidal channels.
Surface Elevation Tables (SET’s):
- Monitored millimeter-level changes in surface elevation and sedimentation rates in relation to physical parameters.
