Data Type(s): Imagery: Photo, Imagery: Video, Location-Elevation: Navigation, Sampling: Geology
Scientific Purpose/Goals: Collecting cores of coral-reef framework (drill coring)
Vehicle(s): Ford F-350 Dually - Silver (GSA), Ford F-350 Dually White (GSA)
Start Port/Location: Saint Petersburg, Florida
End Port/Location: Monroe County, Florida (Islamorada and Marathon)
Start Date: 2015-08-31
End Date: 2015-09-09
Equipment Used: Digital Video, Digital Camera, Garmin GPS, Hydraulic Coring Drill
Information to be Derived: Trends in Holocene reef development
Summary of Activity and Data Gathered: We collected four cores of Holocene reef framework from Tennessee Reef (all of which reached the Pleistocene bedrock). The cores are now being stored in the USGS-SP core archive and have been added to the listings of the digital collections
