USGS scientists and Park manager with coring tool coring of tidal marsh sediments   Elevation survey GPS surveying in the tidal marsh

USGS scientists examine the sediments of the tidal marsh with probe rods and coring tools, while other scientists collect elevation measurements for remotely sensed data. The GPS (Global Positioning System) survey technology allows location and elevation data to be collected in areas that are difficult to access with traditional survey techniques.

The Big Bend coast of Florida appears to alter little over hundreds of years. Yet buried in the sediments is a record of sea-level rise and fall, and of the coming and going of salt marsh and upland plant communities.
