Comments

15CCT02 = Sediment Sampling; 15CCT03 = Twin Vee = RV Jabba Jaw collecting sub-bottom profiler and side scan sonar; 15CCT04 = Jet Ski = RV Chum (blue)collecting Single beam bathymetry; 14CCT04 = Jet Ski = RV Shark (white)collecting Single beam bathymetry Sediment Samples are staged to be archived and are on the East Wall of the Sed Lab as of July 18th, 2018.

Platform

Mako (SP) 17' Mako
Personal Water Craft (White WVR1 - Shark) White WaveRunner, R/V Shark
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.
