Seminar: Improving Odontocete Acoustic Tracking Performance Using More Informative Measures
Zoom Meeting ID______ 935 9608 7383 Passcode: OREseminarPina Gruden, PhD Postdoctoral Acoustic Researcher Joint Institute for Marine and Atmospheric Research, UH Mānoa Passive acoustic monitoring (PAM) is a frequently used tool for various aspects of marine mammal research, including identifying species, their abundance and behavior. Traditionally, boat-based visual line-transect surveys are carried out with the goal of estimating species abundance. PAM is an important addition to visual surveys, especially for elusive species (in which groups are frequently missed by visual observers), species with complex group structure, and species that show behavioral response to boat presence. This seminar will discuss the challenging problem of tracking multiple false
MS Plan A Defense: Detecting spinner dolphin (Stenella longirostris) clicks in noisy and low sampling rate hydrophone recordings

This thesis focuses on click train detection in cases in which sampling rates are too low to capture the full bandwidth of the clicks, and in which impulsive noise confounds current detection methods. We develop an algorithm to detect/classify odontocete click trains based on the regular timing of clicks; the method relies on the slowly- varying nature of Inter-Click
PhD Defense. Of RATs and Men: Underwater passive acoustic localization investigations using relative arrival times and blind channel estimation
HIG 110 2525 Correa Road, Honolulu, HI, United StatesBrendan 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,
Advancements in passive acoustic monitoring: A framework for automated tracking of marine mammals
Watanabe 112 2505 Correa Rd, Honolulu, HI, United StatesDr. Pina Gruden Acoustics Researcher Cooperative Institute for Marine and Atmospheric Research and Department of Ocean Resources Engineering University of Hawaiʻi at Mānoa Location Information **This seminar will be held both in person (Watanabe Hall 112) and over Zoom** Meeting ID: 961 6222 2366 Passcode: OREseminar https://hawaii.zoom.us/j/96162222366 Passive acoustic monitoring (PAM) is an efficient tool for studying acoustically active sources such as marine mammals. Using a variety of sensors and array configurations, PAM can provide insights into species identity, movements, behaviors and abundance of populations, and is thus an invaluable tool for assessing and monitoring populations.
