Field Activity 2017-331-FA

Identifier 2017-331-FA
Purpose Collecting cores of coral-reef framework (drill coring)
Location Dry Tortugas National Park (DRTO) - Pulaski Shoal
Summary Underwater wire-line coring to obtain cores of Holocene the reef.
Info derived Trends in Holocene reef development
Comments Initial survey dates were June 13-27, 2017. An additional site visit will be required to complete data collection activities.
Projects
Platform
Halimeda
Twin Vee (Jabba Jaw)
22-ft Twin Vee This boat has a carrying capacity of up to 1500 pounds and up to 7 people and a shallow draft (9 inches empty). This boat's cat hull design results in a smoother ride in choppy water, at the expense of a slightly deeper draft. This boat is powered by two Yamaha 70hp motors.
Vehicles
Ford F-350 Dually - Silver (GSA)
