Abstract:
Sediment core GeoB23234-1 was drilled using MARUM-MeBo200 at Four-Way Closure Ridge, South China Sea during cruise SO266/1 with R/V SONNE. Gas that has accumulated in voids in the MeBo liners was collected in order to determine the molecular composition of light hydrocarbons (expressed as C1/C2). For this, concentrations of methane and ethane (in mol-% ∑(C1+C2)) were determined by use of gas chromatography.
