Understanding what drives the cycles of gases like carbon dioxide and oxygen is essential to understanding our changing planet. I measure a suite of inert and bioactive gases, like argon and oxygen, to investigate oceanic processes. Dissolved inert gases can tell us about how gases move between the atmosphere and the ocean and what processes drive those fluxes, such as rapid cooling and bubbles created by breaking waves. Dissolved oxygen measurements indicate the productivity of ocean waters. Atmospheric measurements can give us a globally integrated picture of the ocean uptake or release of gases. These different approaches allow my group to investigate a large variety of processes across many spatial and temporal scales.
I am looking for new graduate students to work with me on using dissolved oxygen to measure ocean productivity and on using dissolved N2/Ar to measure loss of bioavailable nitrogen from the ocean. Prospective students will need strong analytical chemistry and quantitative skills. International students should take the GRE exam. Please contact me if you might be interested in pursuing one of these projects.
The Download page contains both dissolved gas databases from my published papers and MatLab scripts for gas solubility and other useful seawater related quantities. I invite collaboration with people interested in using these gases as tracers, particularly modelers.
