Single water samples from MOSES project's cruise stern_2

During Stern_2 cruise single water samples were taken either from a rosette (vertical) or from on the way systems. For the on the way systems a time off-set was calculated and subtracted from the original time. The aim of the sampling was mainly to counter-check with different sensors. More details can be found in the expedition report (Fahrtbericht Moses Sternfahrten). For methane concentrations, water was transferred to glass bottles (120 ml) and stored cold (4°). In the home laboratory a 20 ml head space was created and analyzed via gas chromatography. Magen et al. (2014).
