OCEANIC BIOLOGICAL PRODUCTION OF METHYL BROMIDE
 
Very little is known about the biological rates of production and consumption of methyl bromide in ocean waters, or about the biological players in this biogeochemical cycle of methyl bromide. The mechanism for production of CH3Br in the surface ocean is currently unknown. This is a critical gap in our understanding of the CH3Br cycle. We present here measurements of concentration and production rates for CH3Br in surface waters for a variety of oceanic regimes across the North Atlantic Ocean, Caribbean Sea, and NE Pacific Ocean sampled during May-July 1998. The results presented are part of a larger, four-investigator study designed to evaluate the effects of oceanic, biological degradation and production of methyl bromide (CH3Br) on its uptake by and emission from the ocean, to relate the derived parameters to satellite measurements of oceanic and atmospheric properties, to evaluate the use of satellite data in monitoring oceanic fluxes of this gas, and to incorporate these results into a global ocean-atmosphere model.
