Transient Tracers

: CFC-12 distribution through the Mediterranean Sea

We are measuring gaseous tracers such as CFC-12 and SF₆ in the ocean interior. This provides information about ventilation and circulation.

: The mast of the R/V Tangaroa in Wellington, NZ outfitted with eddy covariance measurement equipment (courtesy of E. S. Saltzman, UCI).

We measure the eddy covariance flux and surface ocean cycling of trace gases important for global climate change and atmospheric chemical processes (e.g. DMS, acetone, methanol).

: The ocean as a source of halocarbons.

We are interested in the air-sea exchange of chlorinated, brominated and iodinated trace gases and in the investigation of their marine sources and the driving factors for their regional and temporal variable oceanic emission strengths, since they have important impacts in the atmosphere.
