Alaska Ocean Acidification Network
Burke Hales is a professor of ocean ecology and biogeochemistry at Oregon State University, and the inventor of the “Burke-o-Lator” a system that has revolutionized shore-based OA monitoring. Burke is a member of the Alaska OA Network and has been involved with all three of Alaska’s Burke-o-Lators.
Q: Tell us about what element of OA you work on, and how you got interested in this topic.
A: I have studied ocean carbon cycling, from the perspective of carbonate chemistry, since I started grad school in 1988. That project focused on how calcium carbonate dissolution in deep ocean sediments was impacted by CO2 produced by respiration, and made use of an autonomous system that measured pH and oxygen concentration over millimeter scales on the seafloor. From there, I moved on to studying surface-ocean and ocean-margin CO2 cycling, where I devised systems for high-speed autonomous ocean sampling and chemical analysis. Ocean acidification is just one facet of ocean carbon cycling, and in some ways, I have been studying that for nearly 30 years.
