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...

Mobile Autonomous Passive Acoustic Monitoring of Marine Mammals in the Catalina Basin

Creator:

Edison, Ciera J. and Fregosi, Selene

Abstract:

Traditional visual survey methods for marine mammals can only detect a fraction of the animals present. Even if the animal can be observed from the surface, visual limitations such as time of day and weather conditions can impede this ability. Recent advances in passive acoustic monitoring technologies have led to...

Development and Evaluation of an Animal-borne Active Acoustic Tag to Conduct Minimally Invasive Behavioral Response Studies on Marine Mammals

Creator:

Fregosi, Selene

Abstract:

Development of new research tools is needed to better understand the potential effects of a noisier ocean on individual and populations of marine mammals. Current behavioral response studies utilize ship-mounted sound sources to induce short-term noise-related behavioral responses in tagged animals. Combining the tag with the sound source into an...
