Water samples were collected with 12 L Niskin bottles mounted onto a rosette sampler during the up-cast. Dimethylsulfide (DMS) was analyzed on a gas chromatograph (Varian 450C) which was coupled to a purge and trap system slightly modified from the method described in Kiene and Slezak (2006). Dimethylsulfoniopropionate (DMSP) was analyzed as DMS after alkali cleavage (Dacey and Blough, 1987) with the same analytical procedure as described for DMS.
