  • Long Term Trends and Sources of Sound in United States Waters

    Creator:
    Haver, Samara M.
    Abstract:
    Passive acoustic monitoring is a valuable tool for observing the status of marine environments. Comparisons of underwater soundscapes over temporal and spatial scales can provide data to inform marine conservation efforts, including protection of threatened and endangered species. This dissertation utilizes passive acoustic data collected via a broadly spaced array...

  • Applications of slow-moving autonomous platforms for passive acoustic monitoring and density estimation of marine mammals

    Creator:
    Fregosi, Selene
    Abstract:
    Advances in mobile autonomous vehicles for oceanographic sensing provide new opportunities for passive acoustic monitoring of marine mammals. Acoustically equipped mobile autonomous platforms, including gliders, deep-water profiling floats, and drifting surface buoys can survey for a variety of marine mammal species over intermediate spatiotemporal scales. Additionally, such mobile platforms may...

  • Humpback Whale (Megaptera novaeangliae) Calling Behavior In Southeast Alaska : A Study In Acoustic Ecology And Noise

    Creator:
    Fournet, Michelle E. H.
    Abstract:
    Humpback whales (Megaptera novaeangliae) are a widely distributed baleen whale species, well known for their diverse acoustic behavior. On high-latitude foraging grounds, humpback whales produce a suite of non-song vocalizations (“calls”) in concert with foraging and social behavior. In this dissertation I investigated the role of calls in the acoustic...

  • The Soundcheck of the Sea : Comparing Marine Soundscapes on a Continental Scale

    Creator:
    Haver, Samara M.
    Abstract:
    Monitoring marine ambient sound using standardized methods supports assessments of ocean sound levels across widespread ecosystems. This thesis quantifies differences among coastal and deep-water marine soundscapes in the Atlantic and Pacific oceans. The sources of sound in a soundscape are compartmentalized into three components and compared over time and among...
