Goal: To determine acoustic based density and abundance estimates for sperm whales in the Northern Mariana Islands, using data collected during a research cruise conducted during the winter and spring of 2007. Time Period: 2015 Our...
Bio-waves is currently conducting towed hydrophone array surveys and advising our research partners, SocioAmbiental and Ecowaves, who are responsible for conducting baseline surveys and tagging of marine mammals in the Santos Basin, a large marine area...
Goal: To collect baseline information on marine mammal behaviors in the Southern California Bight using both acoustic and visual methods. This information is being collected in order to better assess the potential effects of U.S....
Goal: To monitoring delphinids during mid- and deep-water net trawls in order to mitigate accidental captures or injuries to marine mammals. Our Role: To use a towed hydrophone array system to monitor dolphins in...
Mariana Islands Marine Resource Survey (MIMRS) Goal: To collect data on the occurrence of marine mammals around Pagan Island to provide information for the U.S. Military’s Environmental Impact Statement (EIS) related to the expansion...
Goal: Conduct the first ever systematic survey of marine mammals in and around French Polynesia, the Cook Islands, the Phoenix Protected Islands, Tokelau, and Samoa. Time Period: November 2015 Our Role: To provide acoustic equipment, support and...
Chief Scientist, Tom Norris, presenting real-time passive acoustic monitoring results of the a large-scale vessel survey of western Canadian offshore waters at the Acoustical Society of America Meeting in San Diego. See PRISMM project...
We are leading an R&D project to develop a fully digital, three-dimensional, towed hydrophone array system (the 3-D-V Array). It will be capable of obtaining 3-D bearings, and ultimately, localizations to sound sources such...
The Pacific Region International Survey of Marine Megafauna (PRISMM) survey consisted of an extensive line transect survey that included both visual and passive acoustic monitoring components. This was the first systematic survey of marine...
Irrawaddy Dolphin Conservation Kien Giang Biosphere Reserve, Vietnam We are collaborating with researchers in Vietnam who are assessing the occurrence of endangered Irrawaddy dolphins (Orcaella brevirostris) in the Kien Giang Biosphere Reserve, Vietnam. This...
We recently developed a modular system of affordable autonomous recorders called SonarPoint. This system consists of an array of 3-5 recorders that are precisely time-synchronized to allow localization and tracking of marine mammals and...
Chief Scientist Tom Norris recently co-chaired a special session on ‘Passive Acoustic Density Estimation: Recent advances and outcomes’ for the 176th Joint Meeting of the Acoustical Society of America and the Canadian Acoustical Association held in...
Founder and Chief Scientist Tom Norris gave a talk at the Scripps Institution of Oceanography for the American Cetacean Society (San Diego Chapter) about applying new passive acoustic technologies to issues in conservation biology....
