Bathymetric extent of recent trawl damage to the seabed captured by an ROV transect in the Alboran Sea

Bottom trawl fishing is among the most destructive anthropogenic pressures acting on benthic ecosystems, but the full extent of the damage is undocumented because of the limited number of deep-sea observations of impacted regions (e.g., Brennan et al., 2012, 2016). As part of its continuing ocean ex...
