Short summary
In the course of former German environmental impact studies associated with manganese-nodule mining, the DISCOL experiment was conducted in 1989 in the Peru Basin. The disturbance tracks created by a plough harrow in the area are still apparent and could be located by high-resolution mapping techniques. The analysis presented in this study reveals the age sequence and the temporal change of the tracks which facilitates more detailed sample interpretations within the area.
