My research interests are to characterize present-day pH and dissolved oxygen (DO) regimes in coastal upwelling ecosystems and place the observed variability in the context of marine organism exposure histories with particular emphasis on invertebrate larvae. In order to characterize the carbonate chemistry of the inherently variable coastal ocean I am conducting a series of autonomous sensor deployments along the San Diego coastline with the use of SeapHOx packages (DO, pH, T, S, pressure). The observed natural variability is being incorporated into laboratory and in situ transplant experiments to test how pH and DO levels, variability regimes, and physiologically-relevant thresholds affect the health of marine invertebrate larvae. A second project which I am closely involved with focuses on the development of geochemical proxies to evaluate larval pH and DO-exposure history.
