Beschreibung:
This dataset comprises solid-phase total organic carbon contents (TOC) and bulk sediment manganese contents from 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.
