Science that Weathers the Storm: USGS Responds to Tropical Storm Hanna

USGS Scientific Efforts

The U.S. Geological Survey continues to mobilize equipment and personnel to gather the scientific data and information on the impact of Tropical Storm Hanna.

USGS scientists will be:

  • Collecting satellite imagery to assess the impact on wetlands, coasts, and changes in the elevation.
  • Collecting water samples to determine the water quality in areas where there has been significant salt water intrusion.
  • Marking and flagging high-water marks to document flooding and storm surge.
  • Repairing and replacing damaged streamgages to restore flood warning capabilities.
  • Collecting aerial photography and video to document the impact on the coast and wetlands.
  • Using airborne laser mapping systems (LIDAR) to quantify coastal changes.
