Dimethylsulfoniopropionate, dimethylsulfide and inorganic nutrient concentrations measured on Kemmerer bottle samples during POLARSTERN cruise PS94

Water samples were collected with 6.4 L Kemmerer bottles through a hole in the sea ice in several meters distance from the ship. 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 a...

Description
Summary:Water samples were collected with 6.4 L Kemmerer bottles through a hole in the sea ice in several meters distance from the ship. 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. The nutrients phosphate (after Murphy & Riley, 1962), silicate (after Strickland & Parsons, 1968), nitrite and nitrate (after Grasshoff et al., 1983) were analyzed in an air-conditioned lab container with a continuous flow auto analyzer (Technicon TRAACS 800). In-between runs reproducibility better than 1.0 % , but typically 0.8% of its average value.
