PhD Defense. Of RATs and Men: Underwater passive acoustic localization investigations using relative arrival times and blind channel estimation
HIG 110 2525 Correa Road, HonoluluBrendan P. Rideout PhD Candidate Department of Ocean and Resources Engineering University of Hawai’i at Mānoa Location Information **This defense is hybrid** In person in HIG 110 Zoom meeting ID: 935 1677 2350, Passcode: ORE https://hawaii.zoom.us/j/93516772350 Please join us afterwards (~12:30 pm) in the HIG courtyard to congratulate Brendan Understanding the ecology of any organism requires an understanding of all its life stages. Underwater acoustics provides the ability to observe the submerged lives of marine mammals in ways not possible through visual means. The complexities of underwater acoustic propagation yield both challenges and opportunities to extract information from recorded data,
Seminar: Acoustic signal processing for tracking marine mammals
Biomed T 211 1960 East-West Road, HonoluluPina Gruden, PhD Post-Doctoral Researcher Joint Institute for Marine and Atmospheric Research Acoustics provides a useful tool to study various aspects of marine mammal biology, such as species identification, behaviour, habitat use, and abundance estimation. In order to answer these questions the acoustic information needs to be first extracted and processed from underwater recordings. This is a challenging task due to large volumes of data, noise and interfering signals present in the recordings. Moreover, multiple animals often vocalize at once, and their sounds are very diverse, further complicating the extraction and processing problem. This seminar will focus on a tracking
Seminar: Approaching Residency of Marine Robots for Persistent Underwater Autonomy
Marine Science Building 114 1000 Pope Road, HonoluluDr. Zhuoyuan Song Assistant Professor Department of Mechanical Engineering University of Hawai'i, Manoa Persistent subsea exploration and monitoring are of vital significance in many fields including early tsunami warning, oceanography, marine biology, coastal safety, natural resource exploitation, and environmental preservation. An emerging frontier of marine robotics is the endeavor to achieve long-term residency of autonomous underwater vehicles. Supported by subsea infrastructures such as ocean observatories, resident autonomous underwater vehicles (RAUVs) can acquire power and cabled communication from off-shore docking stations. RAUV could provide prolonged dynamic measurements of the subsea environment and attend to emerging remote events promptly. This talk covers
