Conservation for Endangered Reef Fish Yields Results

Nassau Grouper populations increased threefold in response to dynamic fishing management actions in the Cayman IslandsA new study from researchers at the Scripps Institution of Oceanography at the University of California San Diego has documented a successful recovery effort among Nassau Grouper populations in the Cayman Islands thanks to an approach involving government agencies, academic researchers, and nonprofit organizations.The study, published January 6, 2020 in Proceedings of the National Academy of Sciences, used a two-pronged approach including tagging and video census data for monitoring

Aqueos Wraps Up Subsea Inspections Offshore California

Subsea services firm Aqueos Corporation announced Friday it recently completed a diving and remotely operated underwater vehicle (ROV) campaign on the US West Coast.The work scope included level III and IV subsea surveys of three large conventional jacket structures off the coast of California as part of an ongoing structural integrity review of the jackets, and included detailed inspection of welds.Both Close Visual Inspection (CVI) and Magnetic Particle Inspection (MPI) methods were used thoughout the jackets, in water depths ranging up to 365 meters. Also included were detailed cathodic potential

they termed micro-depressions. The micro-depressions average just 11 meters (36 feet) across and one meter (three feet) deep. They have steeper sides than the pockmarks and are often elongated in one direction.Map showing the locations of some of the pockmarks and proposed wind-farm areas off Central California.

Such methane releases could potentially cause the seafloor to be unstable, which could pose risks for structures such

Offshore Wind: Decisions Needed Sooner, not Later

.  Offshore wind proponents are casually confident in references to employment and economic benefits. Those benefits, though, aren’t inevitable.  Laissez faire may not be enough.The topic of OFW and ports and public sector benefits was part of a critical focus at an October forum in California.  Researcher Robert Collier and a team from the UC Berkeley Center for Labor Research and Education presented results from a paper titled “CALIFORNIA OFFSHORE WIND: Workforce Impacts and Grid Integration.”Collier’s study presents some sobering conclusions from the UK, the

TSR Obtains Magnetometer to Aid in Treasure Hunting

;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 for us by Geometrics in San Jose, California. To my eyes, it’s a real beauty.“Underwater magnetometers, which are simply known as ’mags’ to those in the shipwreck treasure business, measure anomalies (variations) in the Earth’s magnetic field, which are caused by the presence of iron and other items with magnetic

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
