Scars in the abyss: reconstructing sequence, location and temporal change of the 78 plough tracks of the 1989 DISCOL deep-sea disturbance experiment in the Peru Basin

Florian Gausepohl, Anne Hennke, Timm Schoening, Kevin Köser, and Jens Greinert Abstract High-resolution optical and hydro-acoustic sea floor data acquired in 2015 enabled the reconstruction and exact localization of disturbance tracks of a past deep-sea recolonization experiment (DISCOL) that was conducted in 1989 in the Peru Basin during a German environmental impact study associated with manganese-nodule mining. Based on this … Read more

Journal of Advanced Marine Science and Technology Society | Simulating the Behavior and the Environmental Effect of Sediment Plumes from Deepwater Mining

Hao Xie, Poojitha D.Yapa Abstract A model for simulating the behavior of sediment plumes from deepwater mining and their re sulting environmental effect is presented. This paper contains the complete model formulation and scenario simulations. The sediment transport model includes both the near field (plume dy namics) and the far-field (passive advection-diffusion) phases. The model can … Read more
