through the water column, potentially searching for food, feeding near the surface and swimming close to the seafloor.It is hoped that further analysis of the many hours of video footage from the AUV, as well as visuals from towed camera tags attached to the sharks and the deployment of advanced sonar imaging, will uncover even more about the underwater behavior, social interactions, group behavior and courtship of the elusive species.“Every time we deploy REMUS SharkCam, we learn something new about the species we are studying,” said WHOI Research Engineer Amy Kukulya and SharkCam Principal

and forward-grazing angle, resulting in an acoustic track over the sea bottom that starts from the port and starboard side and extends diagonally forward across the nadir ahead of the platform.MA-X allows for seamless imaging of the entire swath, including the nadir area where traditional side scan sonar imaging leaves a gap. This gap in data requires overlapping survey lines which leads to additional survey time to achieve 100% coverage.According to Klein Marine Systems, a cost-effective "gap-filler" solution has long been sought by the industry, as Traditional gap-fillers tend to be expensive

rig.Depending on the mission, operators in the rig command center can control the MANTAS remotely and direct its mission manually, or use the USV in an autonomous or semiautonomous mode to search along a predetermined course through the use of preprogrammed waypoints.Most significantly, the video and sonar imaging from the MANTAS can be sent directly to the rig command center in real-time, thereby providing immediate notification of what the USV discovers above or below the water surface, thus enabling operators and management to make time-sensitive decisions regarding rig operations.Anticipating near-term

EdgeTech Delivers ERB for Deewater Acoustic Release Mooring Recovery

EdgeTech, a provider of high resolution sonar imaging systems, acoustic release systems and underwater technology, said it recently delivered an innovative solution for deepwater acoustic release mooring recovery.The Emergency Recovery Beacon (ERB) is a self-contained, programable acoustic command transmitter and transponder in a 6,000 meter rated nickel aluminium bronze alloy housing that can be lowered from the side of a vessel below any surface noise, shipboard noise or thermoclines.The ERB is programmed through a serial port using a computer running a terminal program and can transmit EdgeTech LF

Sonar Helps Find Missing Argentine Submarine

EdgeTech, a manufacturer of high-resolution sonar imaging systems and underwater technology, said its side scan sonar technology was used to help find the missing Argentine submarine, ARA San Juan, which was recently located in 900 meters of water off Argentina's Atlantic Coast after a yearlong search.The deepwater search was performed by Ocean Infinity and its advanced fleet of 6,000 meter rated autonomous underwater vehicles (AUV) equipped with EdgeTech 2205 Side Scan Sonars. The ARA San Juan was imaged by the EdgeTech sonar operating at a frequency of 230kHz and a 400-meter range scale.EdgeTech&r

Klein Selects Greensea Inertial Navigation

the integration activities unfolded smoothly and quickly. The Greensea team was extremely responsive and their support during integration and test was exceptional. The incorporation of a subsystem with this broad range of sensor functions allows Klein Marine Systems to focus on our core competency, sonar imaging, knowing that we are continuously receiving high quality sensor data.”“We are excited that Klein Marine chose Greensea as a navigation partner,” said Marybeth Gilliam, Greensea’s COO. “Our recent integration with their flagship product, the System 5900, is indicative

$17B Spanish Galleon San Jose: EdgeTech Instrumental

more than 300 years, the wreck of the Spanish Galleon San Jose was finally discovered on November 27, 2015 and just recently made public. The search was performed by the Woods Hole Oceanographic Institution (WHOI) Remus 6000 autonomous underwater vehicle (AUV) equipped with an EdgeTech 2200 Side Scan Sonar.  AUV mission planning and sonar data analysis for the project was supplied by GK Consulting of Derry NH. The San Jose was a 62-gun flagship galleon of a Spanish fleet carrying gold, silver and emeralds from the mines of Peru back to Spain.  It was sunk June 8, 1708 in a battle with the

EdgeTech Sonar Utilized in USS Juneau Discovery

EdgeTech, developer of high resolution sonar imaging systems and underwater technology, said its side scan sonar technology was used in another very noteworthy underwater find. Just weeks after locating the USS Lexington, the research vessel Petrel and Paul Allen’s team has located the sunken remains of the USS Juneau.   The USS Juneau, a US Navy light cruiser, was sunk in November 1942 during World War II.  Located in over 4,000 meters of water the historic vessel can be seen in this very clear, low-noise EdgeTech 2205 sonar image.  The amazing image shows the large 2 kilometer

Digital Ocean: Making Subsea Data More Easily Accessible

D-sized cell over distances greater than 150 meters.   The applications for Bluecomm are extensive: used in conjunction with Sonardyne acoustics, low-bandwidth data can be transmitted acoustically (for example by switching on the optics remotely) and high-bandwidth data such as video or sonar imaging data files can be transmitted using the optical method. Data from seabed data storage centers or data-gathering vehicles can be collected by AUVs and then relayed to ASVs or manned surface units for transmission to ground stations via satellite.   Inertial systems – To complement
