The Western Atlantic Climate Study (WACS) campaign was conducted for 9 days in August, 2012 in the Eastern Atlantic Ocean in collaboration with NOAA, from Boston to Bermuda. The goal was to differentiate glyoxal fluxes between oligotrophic and mesotrophic waters using the Eddy Covariance method in conjunction with our CU-LED-CE-DOAS. Complimentary measurements of other trace gases and aerosols were also performed by scientists aboard the RV Ronald H. Brown to study the properties and composition of nascent ocean-derived aerosols.
