interpretation of the data; programming of related software (online visualization
and logging of the seafloor observations)
Geochemical Methods
Pore water and water column analyses
Sediment squeezing under inertial atmosphere; photometric and titration
analyses (e.g. Si, P, NO3, NO2, Cl, H2S, O2) at sea and in onshore laboratories;
water/gas hydrate degassing and gas analysis by gas chromatography (C1 to
C4) at sea and in onshore laboratories
XRD analyses (Debye-Scherrer, Guinier, Phillips diffractometer)
