TSR Obtains Magnetometer to Aid in Treasure Hunting

Treasure & Shipwreck Recovery, Inc. (“TSR”), currently trading on the OTC market under the ticker symbol BLIS, announced that its brand-new cesium magnetometer was delivered. The following is an explanation of what this means by TSR chief operating officer and internationally known shipwreck expert Dr. E. Lee Spence:“This isn’t an off-the-shelf item that you can buy at your local dive shop or treasure hunting store. It’s a state-of-the-art piece of scientific equipment, costing almost $40,000.“Our new magnetometer is a model G882AR/4, made to special order

Blue Robotics Intros Ping360 Scanning Sonar

California-based Blue Robotics announced its newest product, the Ping360 Scanning Sonar, which offers small remotely operated underwater vehicle (ROVs) the ability to navigate in low visibility water conditions.The Ping360 is a mechanical scanning sonar – it uses a small acoustic transducer mounted on a motor that rotates it in one-degree increments.As it rotates, it transmits and receives acoustic pulses to build a 360-degree image of the surroundings. This is similar to laser scanners and LIDARs used for ground robotics and autonomous cars but using sound waves instead of light.When mounted on

a fully automated data gathering system and associated mechanical support equipment. The new facility will be able to measure the acoustic characteristics of sonar system components, including (but not limited to) transducers, hydrophones, small arrays – with the potential of full system and vehicle testing.We will have the capability to perform extensive acoustic, mechanical, and electrical measurements. We hope to fill a void that we feel is mirrored amongst our friends in the community for a facility that is easy to access, easy to schedule, that can provide reliable data in the end-to-end

EOMAP Wins Funding for Next-Gen Satellite-Derived Bathymetry

EOMAP has been awarded by the German Aerospace Center (DLR) to further develop its physics-based method of mapping the depth of the sea from satellite observations.Satellite-Derived Bathymetry (SDB) uses data gathered by satellites and aircraft to generate depth measurements and seafloor characteristics for regions of shallow water. Developed 20 years ago by EOMAP scientists then at DLR (Germany) and CSIRO (Australia), SDB’s potential to create a continuously updated global database of shallow-water bathymetry is hampered by the heavy computing power required to process the large amounts of data

Woodside Backs Seismic Data Acquisition Company

(BOM) to invest in seismic data acquisition company Blue Ocean Seismic Services (BOSS).BOSS is developing a solution that that aims to make ocean bottom seismic data acquisition cheaper and more accessible. The concept, jointly developed by Woodside and BOM, focuses on using autonomous underwater vehicles (AUV) in place of remotely operated underwater vehicles (ROV) to place nodes on the ocean floor that capture and record soundwaves. The BOSS-designed AUVs are small submarines that are pre-programmed to self-deploy to the ocean floor and reposition multiple times. This method will improve efficiencies

NPD Completes Seabed Minerals Expedition

proving deep sea mineral deposits by the Ministry of Petroleum and Energy. The Act relating to mineral activity on the Norwegian continental shelf (the Seabed Minerals Act) came into force on 1 July 2019.A total of 3900 line kilometres of geophysical seabed data was acquired using Autonomous Underwater Vehicles (AUVs) Three AUVs were in operation simultaneously, collecting data as they passed about 50 m above the seabed at a speed of 3 knots. The AUVs operated independently for two days at the time away from the mother vessel.This data acquisition has provided important geophysical data and seabed maps

Increased Confidence in CO2 Storage

the sediment to ensure its exit was three metres beneath the seabed surface. It sounds simple, but in order to achieve this, a bespoke ‘drill’ rig to push the pipe into the sediment was developed and built by Cellula Robotics in Canada. The pipe was then connected by a remotely operated vehicle (ROV) to a CO2 supply on the seabed, allowing gas to flow through the pipe into the sediments. Again, this sounds simple, but specially-designed gas cylinders housed in a second rig had to be built to withstand the tough salt-water environment of the North Sea.Fortunately conditions remained calm

Depredation—when seals and other marine animals prey on fish caught in net—can be costly both economically and ecologically. It can reduce the amount of sell-able fish, damage fishing gear, and lead to the lethal entanglement of seals and other protected marine mammals in fishing nets.

Underwater Cameras Tackle Tough Questions for Fishery

an array of five underwater cameras across the top or “headrope” of a gillnet—a ten-foot tall wall of mesh netting that extends as wide as the wingspan of a 747 jumbo jet—to get an unprecedented view of the encounters. They are also relying on the use of a remotely operated vehicle (ROV) to periodically survey the nets. The ROV takes real-time video snapshots of activity below the surface to supplement the top-mounted cameras.“This is the first time anyone has captured video of active sink-gillnet fishing in the northeast U.S. that we know of,” said Owen Nichols
