VIDEO: Dive Completes Sea Trials with Kraken’s Pressure Tolerant Batteries

Kraken also acquiring a license to build two Dive LD-AUVs for use in Kraken’s growing Robotics-as-a-Service (RaaS) business.“Our team is excited to be working with Kraken Robotics,” said Jerry Sgobbo, Dive President & CEO. “We have always been impressed by the battery and sonar technology coming out of Kraken.”Production of Kraken’s first Dive LD-AUV is currently underway with the first unit being manufactured in the U.S. Kraken expects that it will be delivered to Kraken’s Unmanned Maritime Vehicle Facility in Dartmouth, Nova Scotia for sea trials in the spring

our longstanding commitment to digital advancement has meant we are well positioned to respond to the needs of our customers during this difficult time.”Survey planning and review of hull drawings were completed the day prior to the survey. During the inspection, the surveyor used VUVI’s sonar technology to scan the vessel’s bottom in order to locate the hull equipment, such as echo sounder sensors; speed log sensors and sea chests, while simultaneously assessing the general condition of the hull.The in-water survey was concluded in a similar timeframe to traditional surveys, approximately

How to Remove Abandoned ‘Ghost’ Fishing Gear from the Ocean

and to estimate economic losses.Sustane Technologies Inc. will recycle retrieved rope into diesel fuel. Innovative mapping technologies will be used in partnership with Dalhousie University and the Ocean Tracking Network. Mapping of ghost gear will improve the retrieval process by using side-scan sonar technology to create detailed maps of the seafloor and identify where lost gear has settled.Fishers do not want to lose gear and they recognize that ghost gear continues to harm marine life and impacts their bottom line. Future programs to retrieve ghost gear helps protect marine ecosystems and creates

Mitcham Announces MA-X Sonar Product Deliveries

Mitcham Industries said its Klein Marine Systems unit has completed initial deliveries of new products based on its MA-X "gap filler" sonar technology.  Introduced earlier this year, MA-X technology is a cost-effective solution to filling the nadir gap that is characteristic of traditional side scan sonar.  By seamlessly covering the nadir region, MA-X based products eliminate the need for overlapping survey lines, resulting in an estimated 40% increase in efficiency."The reaction by the industry to MA-X we believe has been nothing short of incredible,” said Guy Malden

FarSounder Unveils 3D Forward-Looking Sonar

yachts from 18 - 40+ meters. As in its other two models the Argos 1000 and Argos 500, the design allows for an easy, fixed installation. The Argos 350 however offers another alternative as well. It can be connected to a hoist in a 10-inch diameter sea chest.As the leader in 3D Forward Looking Sonar technology, FarSounder has kept the yachting community safe from shallows and in-water obstacles since 2005. In introducing the Argos 350 to this new market, these smaller vessels can now enjoy FarSounder’s 3D real-time software and navigate with confidence.

3D Sonar Used in Fishery Research

A collaborative research project aiming to assess pelagic fish species such as menhaden and herring is using an application of 3D sonar technology to increase sustainability and benefit the commercial fishing industry.In Rhode Island, pelagic fish, like the Atlantic menhaden and herring, are commercially important in supporting a large fishing industry, yet the management of pelagic fish is difficult due to the lack of reliable and adequate data. The goal of this project is to develop a methodology to detect fish in the sonar imagery, calculating the biomass pelagic fish present, classify the species

Among the show’s first visitors was Marty Klein, who was instrumental in bringing side scan sonar technology to commercial market. “There was a lot of excitement about the oceans,” he says. “Cities under the sea were going to feed the world. People were building manned submersibles to go exploring in the deep. Aerospace companies were building submersibles, like Lockheed, North American
