| contents | This dataset comprises leached contents of different manganese and iron mineral phases from sediment cores, which were retrieved by a multiple corer (MUC) 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. Furthermore, one of the protected Areas of Particular Environmental Interest (APEI), more precisely the APEI3 north of the CCZ, was visited. For the extraction of various manganese and iron minerals, the extraction schemes after Koschinsky et al. (2001) and Poulton and Canfield (2005) were combined. The leached mineral phases comprise (1) carbonate-associated Mn and Fe (Mncarb; Fecarb), (2) easily reducible/mobilizable Mn- and Fe(oxyhydr)oxides (Mnmobil; Femobil), (3) easily reducible Fe oxides, such as ferrihydrite and lepidocrocite (Feox1) and associated Mn oxides (Mnox1), (4) reducible Fe oxides, such as goethite and hematite (Feox2) and associated Mn oxides (Mnox2) and (5) magnetite (Femag) and associated Mn oxides (Mnmag). The dataset was produced in the laboratories of the Alfred Wegener Institute (AWI) Bremerhaven, Germany. |
