Physical-Biological Interactions of Harbor Porpoise Habitat in San Francisco Bay

Harbor Porpoises (Phocoena phocoena) are a small cetacean that inhabit multiple areas along the Pacific Coast. Historically, population studies have primarily been based on aerial surveys and post-mortem data. Golden Gate Cetacean Research began observing these animals up close in San Francisco Bay in 2008, studying their behavior and identifying individuals. Laura is the first graduate student to work with the nonprofit organization, and will investigate how porpoises use chemical and physical aspects of their surroundings in relation to tide flux in San Francisco Bay Estuary. The goal of her study is to produce a fine-scale habitat model, to make biological predictions based on field observations and physical patterns. Laura recognizes wildlife populations as important environmental indicators of ecosystem history, mechanics, and health. She does not only want to protect these populations, but really strives to scientifically comprehend why it is important to do so. Her research will help improve knowledge on environmental state of the Bay, its ecological significance to surrounding areas, and add scientific significance to pre-existing public conservation awareness.
