Abstract

One of the world‘s biggest manganese nodule fields on Earth is found in the Clarion-Clipperton Fracture Zone (CCZ) in the NE Pacific Ocean at 4-5 km water depth. Commercial deep-sea mining activities will affect the deep-sea environment1. We assess the recovery state of controlled anthropogenic disturbances within the CCZ which were created between 1 day and up to 37 years prior to sampling. Here, we present pore-water and solid-phase data of the upper 20 cm of sediment of disturbed sites in comparison with adjacent undisturbed reference sites. We focus on the impact of anthropogenic disturbances on the geochemical conditions of the sediments.
