The Northern San Andreas Fault (NSAF) stretches from the Mendocino Triple Junction, an area in northern California where three tectonic plates meet, south through the San Francisco Bay area.
Over one hundred years after the devastating Great Earthquake, our expedition explored the NSAF, the history of past earthquakes, and the intertwined relationships between large earthquakes and biologic diversity along this, the fastest moving fault in western North America. Our multidisciplinary exploration helped us to understand how tectonic history relates to biodiversity hotspots, and to be able to predict the response these biologically active areas have to future disturbances.Learn more

Captain Mark Kocina and Sam Kesten work together to raise the sails on the Derek M. Baylis. Under full sail, the Baylis was able to traverse survey lines completely under wind power.Learn more
Oregon State University graduate students Morgan Erhardt and Bran Black deploy and recover a CTD off the back of the Derek M. Baylis. Data from the CTD is used to help calculate sound velocity in water, which is needed for multibeam data collection.Learn more
