Marine Biogeochemistry

EC tower outfitted with sonics, motion sensor, gps, weather station, and gas inlets (A. Zavarsky)


The main focus of my research is ocean-atmosphere interaction. I investigate trace gases that impact people, namely by influencing global climate change and tropospheric chemistry. Another focus of my research is the development of analytical techniques that can be used for laboratory investigations and field campaigns. The research projects in the group are:
1) Development and autonomous deployment of the eddy covariance technique for dimethylsulfide (DMS), acetone, CO2 and N2O open ocean flux measurements
2) Investigation of the oceanic sources/sinks and air-sea exchange of oxygenated volatile organic compounds (OVOCs)
3) Investigation of oceanic sulfur and non-methane hydrocarbon compound (e.g. isoprene) distribution, cycling, and air-sea exchange
4) Determination of the global oceanic source of sulfur to the atmosphere and feedbacks between the middle atmosphere and the ocean surface using data compilations and models (ROMIC-THREAT).
