Ziel der Reise / Objectives of Cruise:
Cruise SO268 is fully integrated into the second phase of the European collaborative JPIO-Oceans project MiningImpact and is designed to assess the environmental impact of deep-sea mining of polymetallic nodules in the Belgian and German contract areas of the Clarion-Clipperton Fracture Zone (CCZ). Leg 1 acquired environmental baseline data in the respective trial and reference areas to develop standards and protocols for impact assessments and recommendations for policy and international legislation. A more technical aim of the cruise was to test tools, technologies, and a concept for the environmental monitoring of future deep-sea mining operations. This comprised oceanographic, biological, microbiological, biogeochemical, and geologic investigations which required the deployment of a multitude of seagoing equipment, such as ROV Kiel 6000 for sampling of sediments, nodules, and benthic fauna as well as carrying out in situ measurements and experiments. AUV ABYSS was used for high-resolution acoustic mapping of the seafloor which has been accompanied by video observations with OFOS. Benthic landers and moorings with acoustic and optical sensors were deployed and recovered for the measurements of oceanographic, physical and chemical parameter. Coring devices (box corer, gravity corer, TV multi corer) were used for collecting sediment samples, and the CTD rosette water sampler and in situ pumps for sampling the water column.
