Description
- To obtain estimates of Nephrops densities through underwater videos with photogrammetric sled. - To obtain estimates of Nephrops burrows dendity. To delimit the distribution of Nephrops in the Gulf of Cadiz. - To obtain estimates of bento-demersal macrofauna density present in the Nephrops fishing ground. To calibrate bentho-demersal macrofauna observed in the underwater videos and those obtained in the beam trawl. To prospect non-draggable areas of the circalitoral and batial to know the state of the bottom and the presence of commercial resources. To gather complementary information on the action of the trawl gear in the seabed. - Oceanographic data collection. - Morphological analysis and acoustic response of the substrate through data acquisition bathymetry and reflectivity, as well as very high resolution seismic profiles of areas already prospected or pending to prospect. To collect of sediment samples for sedimentological and community characterization of endofauna. To explore the Portuguese continental margin of the Gulf of Cádiz near the Spanish border in relation to the continuity of the distribution of Nephrops and characterization seabed.
