West Coast OA Cruise Mission Scientist

Bio: I am a researcher at the Instituto de Investigaciones Oceanologicas (IIO) of the University of Baja California (UABC). I’m a member of Mexico’s National System of Researchers (NSI) and a committee member of the Mexican Carbon Program. I received my Ph.D. in Coastal Oceanography from the UABC School of Marine Sciences in 2000 and did my post-doctoral studies at the Scripps Institute of Oceanography in San Diego. My research centers around the role of coastal oceans ecosystems in the global carbon cycle, including ocean acidification (OA) in coastal ecosystems, interactions between OA and other natural or anthropogenic stressors as  hypoxia, climate change, and air-sea CO2 exchange in coastal oceans.

What I’m doing on this cruise:  We are building on work I was doing as part of the 2007 North American Carbon Program (NACP) cruise. This time, we want to learn how the depth of the aragonite saturation horizon is affected by El Niño conditions. We also need to develop and test empirical equations that will allow us to estimate the state of the carbonate system from hydrographic data collected in the southern part of the California Current System (i.e. the Baja California coastal area).
