View new CMGDS report form

Other ID: none

Status: Completed

Organization(s): USGS, St. Petersburg Coastal and Marine Science Center

Funding Program(s): Subsidence (GX.16.MN00.F2211.00)

Principal Investigator(s): Nicole Khan, Lauren Toth

Affiliate Investigator(s):

Information Specialist(s): Billy Reynolds

Data Type(s): Location-Elevation: Navigation, Location-Elevation: Transects, Sampling: Geology

Scientific Purpose/Goals: Collecting coral framework samples (hand collection) from dredging outcrop exposure. Collecting peat cores and elevation data from mangrove deposits.

Vehicle(s): Rental Vehicle

Start Port/Location: Saint Petersburg, Florida

End Port/Location: Miami Beach and Homestead, Florida

Start Date: 2016-07-06

End Date: 2016-07-12

Equipment Used: Collapsible Tripod, GPS Pole, Ashtech Z-Xtreme DGPS, Peat Corer, Push Corer, Other

Information to be Derived: Evaluation of subsidence on the Florida platform

Summary of Activity and Data Gathered: Collected peat-core records from Swan Key, Biscayne National Park, FL. We collected surface samples for foramineriferal analysis, took cores to reconstruct island stratigraphy (depth to Pleistocene bedrock), and replicate 6 m peat cores from the center of the island that will be analyzed to produce sea-level reconstructions. All sampling locations were surveyed with DGPS.
