with underwater things – underwater cameras, strobes, sonar, boomers and other devices – and was working on a device he called a “mud penetrator”. It was just a converted navy echosounder that he was pulsing to look through the sediment of the Charles River in Boston and Boston Harbor, and sort of by coincidence I came onto this scene.   As a teenager I had been an electronics hobbyist. I had some experience working on these new devices called transistors, and I was able to improve the signals on Edgerton’s devices. At some point Edgerton turned his pinger, and

Boston Harbor Dredging Project to get Underway

The Massachusetts Port Authority (Massport) Board today voted to approve to execute a Project Partnering Agreement with the U.S. Army Corps of Engineers (ACOE) and MassDOT to start the Boston Harbor Dredging Project.  A signed agreement allows the ACOE to bid contracts for construction on a Confined Aquatic Disposal cell (CAD cell), which is needed for the maintenance dredging of the Inner Harbor Main Ship Channel. Maintenance dredging will restore the inner harbor to 40 feet and is the first phase of the larger dredging project. Without maintenance dredging, the harbor will continue to silt

Herbert Joins Phoenix International

assisting The Bent Prop Project with WWII aircraft location in Palau.   Before entering the private sector he served as a NOAA hydrographer aboard NOAA ships RUDE, RAINIER, and on two NOAA Navigation Response Teams based in Norfolk, VA and New York, NY. Survey areas included New York Harbor, Boston Harbor, Narragansett Bay, Chesapeake Bay, Puget Sound, and the coastal regions and fjords of southeast and southwest Alaska. Mr. Herbert worked in support of fleet logistics at NOAA’s Atlantic Marine Center and received the NOAA Office of Marine and Aviation Employee of the Year Award for his

, major emergencies that happen during these events, as well as natural or man-made disasters. The division maintains a number of support units complete with specialized equipment and, since the city includes 41 square miles of water, much of it is designed for the marine environment. When it comes to Boston Harbor; as many criminals have discovered...what goes in, will come out, and it’s usually the Boston Police Department bringing the evidence to the surface. To assist in these operations the division has acquired JW Fishers SeaLion-2 ROV. The highly maneuverable remote controlled underwater

The most recent trials of the Bluefin-12 AUV with integrated Solstice were conducted from Bluefin Robotics’ headquarters in Quincy, Massachusetts, where the AUV was deployed from Bluefin’s vessel, the R/V Resolution, to perform short missions around the Boston Harbor area in approximately 15m of water. Each mission consisted of legs of 500m, during which the AUV flew in a pattern commonly known as ‘mowing the lawn.’  “We are pleased with how quickly we were able to integrate the sonar and collect high-quality data,” said Will

In 2007, NOAA and U.S. Coast Guard shifted ship traffic lanes in Boston Harbor to reduce the risk of collisions between large ships and whale sharks,” said Biól. Rafael de la Parra Venegas, Executive Director, Ch’ooj Ajauil AC (Blue Realm). “We want to do the same – adjust the ship traffic lanes further away from these areas, to improve safety

Program. DSOP is part of DARPA's Distributed Agile Submarine Hunting program (DASH), which aims to develop affordable distributed technology to address Anti-Submarine Warfare (ASW) surveillance needs over large, operationally relevant areas.    In February, Bluefin mobilized a Boston Harbor Cruises' vessel, the Scarlett Isabella, at their dock in Quincy, Massachusetts and transited for over 48 hours towards the testing site. While severe weather brought on by Storm Q forced the team to adjust logistics plans, they were able to successfully conduct six days of operational testing

A training seminar was conducted in Scituate, Mass., and members of the Hull, Mass., lobster fishing community attended. Shortly thereafter, CR began to charter Hull-based vessels for turbidity monitoring during a Boston Harbor islands cable installation, whale observations during blasting activities during the Hubline pipeline project, lobster collections for the Massachusetts Water Resource Authority (MWRA), vibracore and water sampling for the Army Corps of Engineers on Boston Harbor dredging projects, and geophysical

The team has tested its algorithms in the field, creating underwater models of two vessels: the Curtiss, a 183-meter military support ship in San Diego, and the Seneca, an 82-meter cutter in Boston. The group is performing tests this month in Boston Harbor. “The goal is to be competitive with divers in speed and efficiency, covering every square inch of a ship,” Englot says. “We think we’re close.” This research is supported by the Office of Naval Research.
