Other ID: none

Status: Completed

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

Funding Program(s): Sea Turtle Assessment (FWS) (GR.23.MN00.M1B70.00 )

Principal Investigator(s): David Thompson

Affiliate Investigator(s): Karen Frutchey - USFWS Robbin Trindell - FWC Ping Wang - USF

Information Specialist(s): David Thompson

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

Scientific Purpose/Goals: The goal of this project is to assess sea turtle nesting response on different template designs for nourished beaches and how these differ from a "natural beach".

Vehicle(s): Chevy Suburban Silver

Start Port/Location: St. Petersburg, FL

End Port/Location: St. Petersburg, FL

Start Date: 2021-05-17

End Date: 2021-09-17

Equipment Used: GPS Backpack, GPS Backpack, Ashtech ProFlex 800 GNSS Receiver, GPS Backpack

Information to be Derived: Beach elevation profiles and sea turtle nesting locations.

Summary of Activity and Data Gathered: GNSS survey data collected at nest/apex, at the primary dune crest, along the turtle crawl path and along cross-shore transect from the waterline to the point where vegetation became impassable. The cross-shore transects and crawl paths were collected continuously at 10 Hz along each by a person walking with an Ashtech ProFlex GNSS unit mounted in a backpack. Nest/apex, dune toe, and primary dune crest were marked by pausing for 10 seconds at each of those locations while collecting data along the cross-shore transect. Post-processed using the nearest base station data from either a Florida Department of Transportation (FDOT) Florida Permanent Reference Network (FPRN) station or a National Geodetic Survey (NGS) Continuously Operating Reference Station (CORS). Juno - surveyed on 8 days; 157 emergences; 77 nests; 80 false crawls. Jupiter - surveyed on 8 days; 159 emergences; 73 nests; 86 false crawls. Melbourne - surveyed on 10 days; 238 emergences; 69 nests; 169 false crawls.
