Erica’s Ph.D. research at the School of Aquatic and Fishery Sciences (SAFS) uses passive acoustic data and spatial methods to study the behavior and presence of subarctic cetaceans in the Bering Strait and southern Chukchi Sea. With the sea ice retreating earlier and forming later in the year, research is needed to understand how subarctic cetaceans (e.g., fin whales and humpback whales) are extending their residence times in the Arctic during the open water season. Erica uses acoustic data to assess the influence of different environmental variables on the acoustic presence of fin, humpback, and gray whales in the Bering Strait region. Erica completed her B.A. in Integrative Biology at the University of California, Berkeley, and her M.S. at SAFS on maternity denning phenology of polar bears. Her Ph.D. research is supported by the US National Science Foundation Graduate Research Fellowship Program and SAFS. More information on Erica’s research, including publications, can be found on her website.
