Survey tasks requiring hull-mounted bathymetric and side scan surveys, as well as those
requiring towed sensor platforms, have been performed with similar USVs.

performed a similar survey with a SeaRobotics USV-1000
trimaran in 1 meter of water to assess oyster beds in the St.
Lucie River, Stuart, Florida.
The National Institute of Ocean Technology of India began
conducting a survey in December 2011 with a USV-2600
to map current fows and acquire water quality data in the
Gulf of Khambhat in northwest India. The gulf experiences
10-meter tidal swings with tidal currents ranging to 8 knots.
Using a Teledyne RDI 1,200-kilohertz ADCP and a YSI
Inc. (Yellow Springs, Ohio) multifunction sensor, the USV
continues to map water currents in the gulf during full tide

MCM and UXO Mitigation Operations
USVs are starting to play a signifcant role in
autonomous and supervised MCM and unexploded ordnance (UXO) mitigation operations.
In all but the most covert MCM operations,
USVs provide large, reconfgurable payloads,
long endurance and high-bandwidth communications in both shallow and deep water.
Along with traditional shallow-water sites,
recreational diving creates new challenges as
diving is reaching greater depths. Installation of
fber-optic cables and pipelines is also on the rise,
making previously irrelevant UXO dump sites a concern.
Operations using USVs with hull-mounted or towed magnetometers are being used to map large shallow-water sites
with potential UXOs while keeping operators and personnel
out of harm's way.
Since 2009, the Naval Surface Weapons Center in Panama City, Florida, has been using a USV-2600 with an integrated SeaBotix LBV100 ROV and associated launch and
recovery system for MCM and UXO operations.
High-bandwidth communications allow for the operation
of the ROV from a safe distance when deployed from a USV.
