Measurements of oceanic organosulfur compounds and oceanic ammonium made during the Omex-M30_1 research cruise in the North Atlantic during September 1994

The cruise began on 6th September 1994 and ended on 20th September 1994 with a spatial coverage of +51N to +36N latitude and +1E to -16W longitude. The data consists of: -235 measurements of saturation of carbonyl sulfide in the water column (dissolved phase) by gas chromatography and computation from concentration -288 measurements of concentration of carbonyl sulfide per unit volume of the water column (dissolved phase) by gas chromatography -208 measurement of dimethyl sulfide (DMS) per unit volume of the water column by filtration, purging, cryogenic trapping and gas chromatography. -56 measurements of concentration of ammonium (NH4) per unit volume of the water column (dissolved plus reactive particulate phase) by colorimetric autoanalysis See below for further details.
