Ocean Global Change Biology
A major focus of our research is to study the physiology and performance of marine organisms in response to both present-day environmental conditions, and to conditions expected for oceans in the future. We are interested in exploring adaptation as a response to climate change and ocean acidification. Recently, work in the lab has focused on ocean acidification. Here, our goal is to understand the physiological response to low pH/undersaturation conditions of seawater in laboratory experiments. In integrated studies that include lab and field work, we are interested in local adaptation in an ocean acidifcation context. Here, our operational goal is to co-locate oceanographic sensors with "biology" in order to explore the scope for adaptation, acclimatization capacity, and physiological response of marine calcifiers as a function of natural variation in pH, the ocean acidification seascape.
