Field Activity Details for field activity 2021-308-FA

Other ID: none

Status: Completed

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

Funding Program(s): Coastal Sediment Availability and Flux - CSAF (GX.24.MN00.M0Y60.00)

Principal Investigator(s): Daniel Ciarletta, Jennifer Miselis

Affiliate Investigator(s):

Information Specialist(s): Arnell Forde, Julie Bernier

Data Type(s): Electro-Magnetic: Ground Penetrating Radar, Imagery: Photo, Location-Elevation: Benchmarks, Location-Elevation: Navigation, Sampling: Geology

Scientific Purpose/Goals: The study seeks to investigate the past evolution of the Pinellas barrier islands using computer models informed by geology from field sites, including Anclote Key, Honeymoon Island, Caladesi Island, Mullet Key, and Cabbage Key. The primary objective is to quantify rates of coastal change that occurred prior to the 20th century. To inform model simulations of the islands, data to be acquired in this study include ground-penetrating radar (GPR) transects to determine the structure of the subsurface, sediment cores to observe and analyze stratigraphy/sedimentology, and age control of sediments using luminescence dating techniques.

Vehicle(s): Ford F-250 Stone Grey

Start Port/Location: Tierra Verde, FL

End Port/Location: Clearwater, FL

Start Date: 2021-02-16

End Date: 2021-03-12

Equipment Used: Ground Penetrating Radar (GPR), Digital Camera, Choke Ring Antenna, Collapsible Tripod, SP80 GNSS Receiver, SP90 GNSS Receiver, Tripods, Garmin GPS, Vibracorer

Information to be Derived: Subsurface structural features (GPR), sedimentology (cores), age control (cores), and visual geomorphology

Summary of Activity and Data Gathered: GPR lines from Mullet Key vicinity, St. Jean Key, Cabbage Key, Honeymoon Island, Caladesi Island, and Anclote Key were successfully acquired through March, 2021. Coring at the islands was completed in May, 2021 after a hiatus in April to complete work at Fire Island, New York (see 2021-312-FA). Cores from Caladesi, Honeymoon, and Anclote were also reviewed for cultural resources by NPS archaeologist; no cultural resources were encountered either during on-site operations or in further lab analyses to date.
