DEA Receives Teledyne Marine SeaBat T51-R Integrated Dual Head
David Evans and Associates (DEA), a US consulting firm, has taken delivery of Teledyne Marine's SeaBat T51-R Integrated Dual Head (IDH) system.DEA’s use of RESON’s sensors has evolved from the early applications of the SeaBat 9001 through to the SeaBat T51 and Integrated Dual Head solutions in use today. Applications include coastal and inland infrastructure inspections, site characterization and habitat mapping using normalized backscatter, navigation and nautical charting surveys, civil works design and construction surveys, cable and pipeline route surveys and inspection, and

Ocean-Bottom Seismometers Play Crucial Role in Offshore Sensing
Dalhousie University and supported by a partnership of 10 Canadian universities, NFSI was funded through a major Canadian Foundation for Innovation investment with approximately USD$10.77 (C$15 million) allocated for equipment and infrastructure.Core to this is a national pool of more than 120 broadband ocean-bottom seismometers (OBS). Since operations launched in 2023, around 100 of these have been deployed annually in locations ranging from the Arctic to New Zealand. By placing seismometers directly on the seafloor, researchers can detect much smaller offshore earthquakes and determine their locations
