Description
The Western Iberian Margin (WIM) the area of interest for this cruise is located at the slope of the
Southwest coast of Portugal (depths from 200 to 800 meters), where otter trawling is occurring on a
continuous base, targeting Norway lobster (Nephrops norvegicus). The area includes fishing grounds with
different levels of impact (from no fishing to intense trawling and fixed nets). We identified three main
objectives for this sampling campaign:
1) Identify areas of high and low fishing intensity by means of side scan sonar and ROV exploration
2) Sample different areas/depths between 200 and 1000 m water depth for benthos with box corer
and multiple corer
3) Collect sediments from the fished and the non‐fished site with box corer or multiple corer for
onboard experiments in which different measures of ecosystem functioning will be measured
4) Collect colonization trays at food fall site with the ROV (uAveiro)
