Dimethylsulfoniopropionate, dimethylsulfide and inorganic nutrient concentrations measured on Kemmerer bottle samples during POLARSTERN cruise PS78 (ARK-XXVI/3) ...
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...

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. Inorganic nutrients nitrate, phosphate and silicate were determined on an Evolution III Autoanalyzer (Alliance Instruments GmbH, Salzburg, Austria). Methods were modified after Grasshoff (Grasshoff et al., 1998; SEAL Analytical). ... : Sampling with the Kemmerer bottles was part of the “Ice station (ICE)” event. ... |
