Benthis parameters

Gear “footprints” of 14 distinct towed gear groups (eight otter trawl groups, three beam trawl groups, two demersal seine groups, and one dredge group). The footprint is defined as the relative contribution from individual larger gear components, such as trawl doors, sweeps, and groundgear, to the total area and severity of the gear's impact.

Details

For each gear group, a vessel size–gear size relationship parameters can used to estimate gear width and sediment penetration from vessel size (length or power).
