BRIJONNAY MADRIGAL

PhD Student

I am interested in understanding the acoustic behavior of odontocetes, vocal repertoire geographic variation and the impacts of anthropogenic noise on acoustic behavior. Using a variety of passive acoustic monitoring techniques, I seek to better understand the acoustic behavior and effects of noise on two resident species to Hawai‘i, false killer whales and pilot whales, in the Papahānaumokuākea National Monument and the Hawaiian Islands Humpback Whale National Marine Sanctuary. My project will allow us to better understand the impacts of anthropogenic noise on vocal repertoires and rates to inform management within protected areas in the Hawaiian archipelago.

Biography

Brijonnay earned a B.S. in Marine Biology and B.A. in Communication from the University of Hawai‘i at Mānoa in 2016. She earned her M.S. in Marine Science from Moss Landing Marine Labs (California State Monterey Bay) in 2019 where she conducted her thesis work on killer whale calls, developed a vocal catalog and identified ecotype presence in the Chukchi Sea. During her time in the Vertebrate Ecology Lab, Brijonnay conducted a field study on Risso’s dolphin acoustics in Monterey Bay and served as a researcher on a NOAA Fisheries Ecology Division project to characterize rockfish survey vehicle noise in the Channel Islands. Brijonnay is a recipient of the NOAA Nancy Foster Scholarship and looks forward to pursuing her passion for marine science research while also engaging in sanctuary education and outreach.
