coring of tidal marsh sediments |

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 sediments is a record of sea-level rise and fall, and of the coming and going of salt marsh
and upland plant communities.
