The NMFS AUV



The NMFS autonomous underwater vehicle, or AUV, before deployment from the Scripps Institution of Oceanography pier. The AUV is rotated on its side to show the bottom instrumentation, which includes a 38 kHz echosounder, a camera with strobe, and an acoustic doppler current profiler (ADCP). The AUV is programmed to conduct dives and return to the surface where it can be retrieved.

AUV echogram with fish



This is an echogram recorded by the autonomous underwater vehicle (AUV) using its 38 kHz echosounder. The echogram shows the sea floor and a school of fish in the water column.

SWFSC Instrumented Data Buoys

These are two instrumented data buoys on board the deck of the R/V Yuzhmorgeologiya before deployment in the nearshore waters off the Antarctic peninsula. The bouys are instrumented with acoustic doppler current profilers and multi-frequency echosounders.

CTD cast



SWFSC Advanted Survey Technologies staff member Josiah Renfree readies a Seabird CTD for deployment from the NOAA Ship David Starr Jordan during the COAST survey in 2007. A CTD collects physical oceanography data (conductivity, temperature, and depth), which the AST staff uses to determine the sound velocity depth profile for processing acoustic data collect during the cruise.Date: 05/07/2007Key words: CTD, ASTContact: SWFSC's Advanced Survey Technologies Program

Drop Target Strength Array 

The drop target strength array is a self-leveling 38 kHz transducer that can be lowered down from the ship to be closer to the acoustic targets (e.g. fish schools).  It is being launched from the NOAA Ship Oscar Dyson.

F/V Outer Limits Transducers



This is the transducer array mounted on the hull of the F/V Outer Limits. The array includes multi-frequency echosounders and two multiple frequency side-scan sonars. Date: 09/21/2009 Key words: AST, transducers, F/V Outer LimitsContact: SWFSC's Advanced Survey Technologies Program

General purpose transceivers



Dr. David Demer monitors the general purpose tranceivers aboard the F/V Outer Limits at 43-Fathom Bank off of southern California. The tranceivers are the "brains" of the transducer system, controlling the transmission and reception of the acoustic signal.

FasTowCam



SWFSC Advanced Survey Technologies (AST) program contractors Mike Paterson and Derek Needham, and AST staff member Steve Sessions next to the FasTowCam system aboard the NOAA Ship Miller Freeman in Puget Sound. The FasTowCam is a new instrument that has stero cameras on its sides. The device is towed at a selected depth behind a ship and the images it gathers help identify and size acoustic targets while underway.Date: 11/05/2009 Key words: AST, FasTowCamContact: SWFSC's Advanced Survey Technologies Program

FasTowCam deployment



Derek Needham (Advanced Survey Technologies (AST) program contractor) and Dr. David Demer (AST program leader) aboard the R/V John Martin in Moss Landing. Derek is monitoring the FasTowCam, while David is monitoring the acoustics. This was a collaborative cruise with Monterey Bay Aquarium Research Institute (MBARI) to investigate jellyfish and sardine occurrence.Date: 11/06/2009Key words: AST, FasTowCamContact: SWFSC's Advanced Survey Technologies Program

Miniature Echosounder



The black instrument shown in the center of this image is a miniature echosounder that was deployed at 150m depth below a Scripps Institution of Oceanography buoy stationed off Pt. Conception. The echosounder looks upwards towards the surface and collects acoustic data.

They are taking the R/V Dale Van Holliday out of Mission Bay, San Diego, California to test and deploy the AUV.Date: 01/17/2008Key words: AST, AUV, autonomous underwater vehicle, R/V Dale Van HollidayContact: SWFSC's Advanced Survey Technologies Program

NMFS AUV off Point Loma, CA



In this photo the NMFS autonomous underwater vehicle (AUV) is seen on the surface after finishing a test run. AST staff members use the raised antenna to communicate with the AUV from a nearby vessel or observation point.

NMFS AUV Entering Customized Cradle for Retrieval



In this photo the NMFS autonomous underwater vehicle (AUV) is seen being actively steered into a custom-built cradle. This system was developed by SWFSC AST staff members to deploy and retrieve the AUV from a hoist without the need for a vessel or person in the water.

NMFS AUV in Custom Cradle Being Retrieved After Deployment



In this photo the NMFS autonomous underwater vehicle (AUV) is being raised out of the water by a hoist on the Scripps Institution of Oceanography pier using a custom-built cradle. This cradle system allows for easier deployment and retrieval of the AUV from a shore or ship-based platform.
