    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

    Description: 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.

    Geochemistry of sediment cores during SONNE cruises SO242/1 and SO242/2 at the DISCOL area, Peru Basin (2019)
    PANGAEA
    Details
    Publication Date: 2024-02-16
    Description: This data compilation includes geochemical data on the solid and solute phases of the seafloor sediments in the DISCOL area in the Peru basin (South Pacific). The DISCOL area represents a part of the deep sea that is extensively covered with manganese nodules and represents a unique study area, where in 1989 a circular area with a diameter of about 2 nautical miles was intensely disturbed with a plough-harrow. The presented data was collected during the two legs of the SO242 research cruise in 2015 with the aim to better understand the ecological impacts of deep-sea seafloor disturbances (e.g. through nodule mining operations). Several devices were deployed at each sampling site to retrieve surface and subsurface sediment samples: (i) a Oktopus multiple-corer (MUC), which samples the upper 20 – 40 cm of the sediment including the overlying bottom water; The corer was equipped with a TV-Camera system for precise positioning, e.g. for sampling specific seafloor features like the disturbance tracks; (ii) a ROV-deployed push-corer (PUC) focusing on small-scale topographic features created by the seafloor disturbance; (iii) a box-corer (BC - USNEL Spade Corer) to sample the sediment inclusive macrofauna as well as associated nodules; and (iv) a gravity-corer (GC) extracting sediment up to 10 mbsf.
