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...
Our Senior Bioacoustician, Jeff Jacobsen (JJ) first conducted research in the Revillagigedo Islands in 1987, and continued this effort for almost 20 years. JJ took a 10 year hiatus from this challenging research project to focus...
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...
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 provide the monitoring necessary prior to a naval training event, the Submarine Commander’s Course exercise in February 2012, to adhere to the guidelines of the U.S. Navy’s Integrated Comprehensive Monitoring Program Time Period: January...
Goal: To help the U.S. Navy in the first systematic line-transect visual and acoustic survey of the waters around the Northern Mariana Islands and Guam, to determine population density estimates for marine mammals and sea...
Goal: To develop and apply bio-statistical methods for assessing the effects of sonar on marine mammal acoustic behaviors. Time Period: 2009-2013 Our Role: To process recordings of delphinid vocalizations (whistles) and sonar to extract variables that will...
Goal: to evaluate the effects of recording depth, animal behavior and sound propagation characteristics of the water column on whistles and clicks produced by delphinids Time Period: May 2015 – September 2016 Our Role: to collect field...
Goal: To develop a prototype tetrahedral array for towed array surveys of deep-diving species of cetaceans. Time Period: Fall 2015- Spring 2016 Our Role: With our partners, UCSD/Scripps Institute of Oceanography’s Marine Physical Laboratory...
Goal: Create fully automated classifiers for odontocete species that use information from whistles, clicks and the context of acoustic encounters and integrate these classifiers with PAMGuard and Ishmael software packages. Time Period: May 2014...
