Figure 6. Trawl-induced and natural sediment accumulation rates in the studied submarine canyons.

Stacked bars are divided by the natural sedimentation rate and the overall enhancement of sedimentation rates as a consequence of trawling modernization (trawling-induced) sediment resuspension associated to this activity. Numbers next to each sediment core affected by trawling activities indicate the increase factor of sedimentation associated to trawling activities after the industrialization of the trawling fleet (1960 s–1970 s). This map was generated using ArcGIS 10.3 (http://desktop.arcgis.com/en/arcmap/10.3/main/get-started/whats-new-in-arcgis.htm). Bathymetric information was obtained from a north-western Mediterranean Digital Elevation Model⁶⁶.
