Field work

During this field campaign, Yuting and collaborators built several long-pathlength adsorption photometric systems on the platform of an aluminum tower. These advanced instruments allowed continuous, high-resolution, and sensitive data collection for the concentrations of nitrous acid, nitrogen dioxide, nitric acid and particulate nitrate (at parts-per-trillion level) in the marine boundary layer. We also collected marine aerosol samples for further chemical analyses and photochemistry experiments.

During this research cruise, Yuting performed shipboard measurements of carbonyl concentrations (at nanomolar level) in seawater with a high-performance liquid chromatography, and conducted incubation experiments on the deck studying carbonyl photoproduction rates in seawater.

Yuting was also involved in an interdisciplinary research project studying the removal of refractory dissolved organic carbon through bubble-bursting processes. 

Yuting participated in a collaborative study that investigated the carbon pool and optical properties of seawaters, and the photochemical reactivity of deep refractory dissolved organic carbon.
