The scientific work during cruise SO268 was part of the second phase of the MiningImpact project (Environmental impacts and risks of deep-sea mining) and is designed to assess the environmental impacts of deep-sea mining of polymetallic nodules in the Clarion-Clipperton Zone (CCZ) in the Pacific Ocean. Ex-situ oxygen was determined onboard using amperometric Clark type oxygen microelectrodes (Unisense, DK).-117.0131667-117.0124511.8626833311.86436667Federal Ministry of Education and Researchhttps://doi.org/10.13039/50110000234703F0812FJPI-O MiningImpact: Auswirkungen von Manganknollenbergbau auf biogeochemische Prozesse und die Ausbreitung von Stoffen in der Tiefsee
