    PANGAEA
    Details
    Publication Date: 2023-05-04
    Description: In order to account for dilution effects of carbonate layers, metal data has been CaCO3 corrected for better comparison within and between the cores.

    Publication Date: 2023-07-07
    Description: Video showing the gas release experiment, which has been conducted at ~80 m water depth in the vicinity of the Sleipner CO2 storage site in the North Sea. The gas discharge was observed in situ during a 4 hour dive with GEOMAR's remotely operated vehicle ROV Kiel 6000 equipped with HD camera/video device.

    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.

    Porosity data for sediment cores taken in small-scale disturbance tracks and undisturbed reference sites during SONNE cruise SO239 in the Clarion-Clipperton Zone (CCZ) (2019)
    PANGAEA
    In:  Supplement to: Volz, Jessica B; Haffert, Laura; Haeckel, Matthias; Koschinsky, Andrea; Kasten, Sabine (2020): Impact of small-scale disturbances on geochemical conditions, biogeochemical processes and element fluxes in surface sediments of the eastern Clarion-Clipperton Zone, Pacific Ocean.

    Publication Date: 2024-02-02
    Description: This dataset comprises porosity data from undisturbed reference sites sampled by a multiple corer (MUC) and disturbed push-cores (PUC), which were retrieved using the ROV Kiel 6000 (GEOMAR) during RV SONNE expedition SO239 in 2015. During this cruise, different European contract areas for the exploration of polymetallic nodules in the area of the Clarion-Clipperton Zone (CCZ) were visited (BGR, IOM, GSR, IFREMER), which are currently being explored in light of potential future deep-sea mining. The PUCs were taken in several small-scale disturbance tracks, which were created 1 day to 37 years before sampling for the simulation of deep-sea mining activities in the different exploration areas. The sampled disturbance tracks include 1-day- and 3-year-old EBS tracks (created with an Epibenthic sledge), 8-months- and 37-year-old dredge tracks, and a 20-year-old track from the Benthic Impact Experiment in the IOM area (IOM-BIE). The dataset was produces in the laboratories of the Alfred Wegener Institute (AWI) Bremerhaven, Germany.
