    TRACTION - a transport reaction model specifically designed to account for non-ideal transport and reaction effects (2018)
    PANGAEA
    In:  Supplement to: Haffert, Laura; Haeckel, Matthias (2019): Quantification of non-ideal effects on diagenetic processes along extreme salinity gradients at the Mercator mud volcano in the Gulf of Cadiz. Geochimica et Cosmochimica Acta, 244, 366-382, https://doi.org/10.1016/j.gca.2018.09.038
    Details
    Publikationsdatum: 2023-01-13
    Beschreibung: Presented is an example of the transport-reaction code (TRACTION) applied to the simulation of pore water species in the seawater mixing zone at Mercator Mud volcano in the Gulf of Cadiz. TRACTION was specifically designed to account for non-ideal transport effects in the presence of thermodynamic (e.g. salinity or temperature) gradients. The model relies on the most fundamental concept of solute diffusion, which states that the chemical potential gradient (Maxwell's model) rather than the concentration gradient (Fick's law) is the driving force for diffusion. In turn, this requires accounting for species interactions by applying Pitzer's method to derive species chemical potentials and Onsager coefficients instead of using the classical diffusion coefficients. Electrical imbalances arising from varying diffusive fluxes in multicomponent systems, like seawater, are avoided by applying an electrostatic gradient as an additional transport contribution.

    Heat flow data during Maria S. Merian cruise MSM34/2 (2020)
    PANGAEA
    Details
    Publikationsdatum: 2023-04-27
    Beschreibung: Data for estimating heat flow in the western Black Sea are provided, based on measurements made during Expedition MSM34 (R/V Maria S. Merian). Data are located in the Bulgarian and Romanian Sector of the Black Sea in water depths ranging from 420 to 1500 m. Data were always collected with the GEOMAR-owned 6 m long heat-probe tool, consisting of 22 Thermistors (at 26 cm spacing) along a sensor-string, a reference pressure gauge and calibration thermometer (T100 sensor). Raw data are required to be calibrated relative to the T100 sensor. Calibration data for both expeditions are provided in form of temperature offsets for each thermistor. Data provided include per station all original (raw) data for each deployment (temperature as function of time, pressure/Depth) for each thermistor, as well as initial results after separating each individual measurement sequence into penetration files (pen-files) where the temperature calibration has been applied. Results report an average thermal Gradient, heat-flux and thermal conductivity over the total penetraiton Depth of 6m. Detailed information (temperature and thermal conductivity as function of depth at each location) is given in graphical form as well as ascii data per individual penetration.

    Details
    Publikationsdatum: 2023-07-04
    Beschreibung: During RV SONNE cruise SO242/2 (September 2015) to the DISCOL site in the Peru Basin (SE Pacific) push cores of sediment were taken in the abyssal plains with ROV Kiel 6000 (GEOMAR). The sediment cores were sliced in 0-2 and 2-5 cm intervals and stored frozen until further processing ashore. In the lab on land, sediment samples were freeze-dried, ground to fine powder, phospholipid-derived fatty acids (PLFAs) in the sediment were extracted following the Bligh and Dyer method and they were measured on a gas chromatograph coupled with an isotopic ratio mass spectrometer (EA-c-IRMS).
