Bio-Waves, Inc. is constantly developing and improving technologies, including hardware for researching and monitoring marine mammals, and software for data analysis, detection and classification of marine mammal sounds both in real-time and post-processing applications. See below for some examples of our hardware and software developments. Contact us if you have a need to design, develop or modify passive acoustic technologies for your specific needs.
ROCCA (Real-time Odontocete Call Classification Algorithm)
Bio-Waves researchers and software engineers have developed a free PAMGuard-based whistle classification program called ROCCA, which is used to identify delphinid species based on their whistles. ROCCA can be used to extract whistles and tonal calls from spectrograms, measure acoustic features, and use those features as inputs to one of several random forest classifiers developed for species identification.

Autonomous Acoustic Recorders (microMars)
MicroMARS is a low-cost, miniature Marine Autonomous Recorder System (MARS). This technology development effort was funded through NOAA’s Advanced Technologies Working Group via a grant to the Northwest Fisheries Science Center who then contracted Desert Star Systems and Bio-Waves. MicroMARS was designed to be a small, inexpensive option for autonomous recording of acoustic data from the marine environment. Read More
Towed Hydrophone Arrays
Bio-Waves, Inc. has researchers and engineers with expertise in the design, fabrication and field-application of towed hydrophone arrays. We have built several towed array systems for use in numerous marine mammal research projects in a variety of marine environments, ranging from the arctic to the tropics. We have custom designed hydrophone arrays and components (e.g. pre-amplifiers) for specific research goals and species groups, and we are constantly working to improve our technology. Read More
Bio-Waves, Inc. has helped The U.S. Coast Guard design and test a portable sonobuoy system to help monitor and mitigate potential impacts to marine mammals during their at-sea training around the main Hawaiian Islands. In another unrelated project for the U.S. Navy, we deployed sonobuoys from small airplanes to monitor acoustic behaviors of baleen whales and large odontocetes in real-time while visual observations of marine mammal behaviors were simultaneously being recorded.
