Abstract

Oceanic bromocarbons are highly reactive volatile organic compounds and may contribute up to 40% of stratospheric ozone depletion in mid latitudes. High sea-air fluxes of bromocarbons in the tropical regions have been related to biological cycling in the surface ocean, mainly by phytoplankton and bacteria, but the underlying processes and magnitude of the biogenic sources and sinks are poorly known.
In order to understand temporal and spatial fluctuations of oceanic bromocarbons emissions, we studied microbial production and removal
processes in the surface ocean during research cruises with RV SONNE (Tropical Indian Ocean) and RV ALKOR (Central Baltic Sea).
