Field Activity 12BIM04

Identifier

12BIM04

Purpose

Barrier Island Mapping Change

Location

Chandeleur Islands, LA

Summary

Single-beam bathymetry

Info derived

Barrier Island Mapping Change

Projects

Barrier Island Evolution Research - BIER Sedimentology

Platform

22-ft Twin Vee (R/V G. Hill)

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.
