3WaveGlider Autonomous Surface Vessel, Liquid
Robotics
- Wave energy provides thrust, surface float 2m
long glider 7m down - Solar energy or batteries power payloads
- Can travel to remote areas
- Full satellite comms
- Variety of sensor options
- Low operating costs

Jaguar/Pumahas worked worldwide, including under
ice in arctic. Includes 3D HDTV, other sensor
options. Speed _at_0.5kt, 24 hr endurance
10Jaguar/Puma AUV has small shipping footprint,
requires team of only 3 operators are 3 vehicles
and teams available. Does not require large ship.
11Transponders can be used for precise benthic
positioning, or AUV can be acoustically tethered
(without transponders)
12Problem Untrawlable Habitat
13AUV Can be Used for Essential Fish Habitat
Surveys as in the Stellwagen Bank Marine Sanctuary
14Puma seafloor AUV HD Video quality results
15Distribution and anemones and sponges at 85E
16ROV Ops under ice First melt a hole
17Testing the Small ROV

19COVIS Cable Operated Vent Imaging Sonar at
Neptune Observatory, B.C.,uses a Reson 7125
multibeam sonar to measure vent plumes
20COVIS setup showing range in one mode range in
vertical can be greatly increased by altering
scan angles
21COVIS results on vent plume intensity and velocity
22HF Surface Current Radar Maps, Zoomed in,
satellite view, So.Cal.Coastal Ocean Obs. System
23HF Radar Surface Current Mapping
- Records surface currents _at_every 20 minutes
- Best if multiple locations along coast are used
- Ice reflection stronger than surface currents
- Can discriminate ice movements and surface
currents - Does best (furthest range) with some seas
- Range _at_30-100km depending on seas, radar
- Requires remote power which has been developed
- Units can be airlifted in along coast
24HF Radar Surface Current Mapping
- In GoM, Louisiana had no HF radars, offer to do
emergency install got bogged down in government
inter-agency discussions, never happened could
have improved shore party deployments - Off Alaska North Slope and Canada coastal
coverage is incomplete, but new remote power
developments could facilitate gap-filling and
emergency deployments - Commerical provider taking steps to maintain
spare inventory for emergency responses - Coverage of Chukchi coast and Bering coasts very
spotty / inadequate at present - Ice and surface current separate flow studies to
date only demonstrated in 2 day study longer
studies would be useful to make these
measurements more routine, reliable
