Postdoctoral Fellow (NSF-Funded)

The Coastal Biogeochemical Sensing and the Chemical Sensor group at the Monterey Bay Aquarium Research Institute (MBARI) are currently seeking a postdoc to join the team. The postdoc will work on a multi-institutional, NSF-funded project to improve the accuracy of air-sea CO2 flux estimates from pH profiling platforms such as floats and gliders. Through a recently funded separate NSF project, the Global Ocean Biogeochemistry array (GO-BGC), we plan to deploy hundreds of BGC profiling floats equipped with pH sensors across the globe over the next several years.

One powerful application for these floats is to estimate ocean CO2 flux on regional to global scales over seasonal to interannual timescales. The quality of the calculated flux, however, is contingent on accurate estimates of pCO2 from float pH, with robust uncertainties. Thus, the main objective of this proposal is to improve the accuracy of pCO2 estimates from profiling pH sensors. This 3-year project consists of a series of laboratory experiments to quantify the pressure dependence of thermodynamic constants used to convert pH measurements to in situ pressure, explore the causes of the internal inconsistency of the marine carbonate system, and field experiments to validate laboratory experiments using underwater gliders and Wavegliders in Monterey Bay. The postdoc will be expected to lead all aspects of this project, including data collection and interpretation, project reporting, manuscript preparation, and communicating key results with collaborators and the broader scientific community. The project will be conducted at MBARI under supervision of Dr. Yui Takeshita, with close coordination with the Chemical Sensor group.

A Ph.D. in chemical oceanography, analytical chemistry, or a related field is required. Extensive experience and knowledge of the marine carbonate system thermodynamics, instrument development, as well as demonstrated proficiency in Matlab, R, Python, or similar is highly desired. Willingness to work at sea on day trips, as well as potential week long cruises is also required. The candidate will work with a diverse group of engineers and scientists, thus, strong communication skills are desired.
