Abstract

Two separate studies in different oceanic regions provide evidence for the production of methyl bromide (CH₃Br) by the prymnesiophyte Phaeocystis. A sampling program to study the seasonal cycle of CH₃Br in a coastal area demonstrated that the seawater was supersaturated with respect to CH₃Br for over 3 months of the year. The greatest saturation was observed during a bloom of Phaeocystis. Also, in situ field measurements demonstrated that CH₃Br was supersaturated over a large region of the northeast Atlantic. A positive correlation was observed between CH₃Br and dimethylsulphoniopropionate (DMSP), indicating that there was a source common to both compounds. An accessory pigment, hexanoyloxyfucoxanthin, which indicates the presence of prymnesiophytes, also correlated positively with CH₃Br.
