Research Abstract

We conducted systematic measurements of marine-derived halocarbons in the air and in the ocean. Full picture of methyl halides distribution in north-west Pacific and Indian Ocean was obtained from the shipboard measurements. We also found that the strains of cryptophytes and cyanobacteria produced halocarobons during decline phase, and that the in vivo biogenic emission of methyl iodide from marine microalgae was dependent on S-adenosyl-L-methionine (SAM) halide ion/thiol methyl transferase (HTMT) reaction.
