DOLPHIN: Enabling Technology for Acoustic Systems

DOLPHIN Signal Processing TechnologyAcoustics enable many core undersea capabilities. Where radio waves do not propagate well, and light is absorbed quickly, acoustic signals help us map, see, locate and communicate. The many products and technologies that employ acoustics all depend upon signal processing, thus new processing approaches can impact many applications.  QinetiQ North America (QNA) and its partner Optimal Systems Laboratory (OSL) have developed DOLPHIN - a patented method using analog cancellation that eliminates receiver saturation and enables simultaneous transmit and receive.

French Frigate Sonars Get an Upgrade

Since summer 2017, four vessels equipped with analog sonars have been upgraded using RTsys AS3i technology (Analog Surface Ship Sonar Improvement), which digitalized and improved the processing of signals rendered by sensors.Brittany-based company RTSYS does not only deals with AUV, subsea recorders and buoys, but can also display a full range of sonar systems such as handheld devices for divers or sonar retrofit. The latter of which led the French SME to lately offer in summer 2017 its services to the French Navy by upgrading analogue sonars on four frigates.In accordance with the ACORES public

Subsea Mining: The Next Big Thing for UUVs

In Europe, there are sure signs that underwater mining is the next big market for autonomous underwater vehicles (AUVs), remotely operated vehicles (ROVs) and new “drones” called HROV, DART or TURTLE. Among the indicators is the involvement of mining companies, governments, rich subsea players and the Dutch dredging community. New vehicles are being developed from Hungary to Hawaii, although Portugal, it seems, is at the forefront of new-vessel commercialization.Apart from dredging up gold and diamonds nearshore, underwater mining is about two activities: tapping the leftover mineral

an early age, I was fascinated by the maritime industry, so it was either commercial fishing or the oil field. I chose the oil field and, specifically, the subsea industry. I studied electric and electronic engineering at college, and began my career with a subsea construction and diving company as a hydrographic survey engineer working on positioning and navigational equipment. That company also had a small fleet of ROVs, (which at the time) were an emerging technology. I was interested in this technology, along with the variety of work scopes where ROVs could be involved, and the potential they had to

U.S. based Ocean Infinity said it has been awarded a contract from the Government of South Korea to search for the wreckage of lost bulk carrier Stellar Daisy, which sank on on March 31, 2017, with 24 people on board.The Stellar Daisy was transporting iron ore from Brazil to China when it was lost in the South Atlantic Ocean, approximately 2,500 nautical miles due east of Uruguay.Ocean Infinity said it expects to commence search operations in January 2019 using its high-tech fleet of autonomous underwater vehicles (AUVs). The company's CEO, Oliver Plunkett, said, “For the sake of all

New Research on Gulf of Mexico Loop Current

the Loop Current Campaign: Data Compilation to Improve Understanding, Simulation and Prediction of the Loop Current SystemThis project will design, develop, deploy, and maintain an information system to digitally compile, update, analyze, and make publicly accessible physical oceanographic and hydrographic data from Gulf of Mexico Loop Current field studies. The system will be an important component of future data compilation efforts for a long-term LCS research campaign. Award Amount: $647,813Project Director: Barbara Kirkpatrick (Gulf of Mexico Coastal Ocean Observing System Regional Association)Projec

Full-Depth Current Profiling Around the Global Ocean

in how deep currents take part in the global climate system. Especially important are the changing heat and CO2 content of the deep ocean.Methods for observing the deep sea below the upper seasonal layer are established. For measuring deep currents, scientists worldwide attach compact ADCPs to hydrographic packages. These packages are routinely lowered to the seabed to catch water samples and to measure water properties.In this report we look at various findings from LADCP work around the global ocean. LADCP measurements were initially looking at deep currents in equatorial regions and in tropical

Subsea Robotics: SOI Mission Discovers New Hydrothermal Vent and Species

AUV, ROV Seafloor Mapping Systems Used on an expedition aboard Schmidt Ocean Institute’s R/V FalkorSchmidt Ocean Institute’s R/V Falkor recently discovered a spectacular new hydrothermal vent field, named JaichMatt, in the Souther Pescadero Basin, Gulf of California.The vents were identified using Monterey Bay Aquarium Research Institution’s (MBARI) Dorado autonomous underwater vehicle to conduct exploratory seafloor surveys with one meter lateral resolution. Simultaneously, MBARI's new Low Altitude Survey System was used from Schmidt Ocean Institute’s ROV SuBastian to map
