Field Activity 2018-350-FA

Identifier 2018-350-FA
Alternate names 18BIM01, 18BIM02
Purpose 1) Measure bathymetric change and borrow site deposition on the N. Chandeleurs island platform and 2) Single-beam bathymetry of the long term change lines.
Location Chandeleur Islands, LA, Gulf of Mexico
Summary Collected 36 seismic, 70 single-beam bathy and 112 multi-beam bathy lines.
Info derived Bathymetric elevations (both multibeam and single-beam), depositional stratigraphy, and bench mark elevation control

Platform
Sallenger
25' Parker
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
Chevy Suburban Silver
Ford F-350 Dually White (GSA)
