BUSCADOR RECOLECTA

DESEAS Cruise (29GD20010606) carried out on the Research Vessel García del Cid in 2001, The object of the DESEAS Project, funded by the EU, was to gather preliminary data on the abundance and maximum depth distribution of the rose shrimp Aristeus antennatus in the Mediterranean SeaThree deep-sea areas in the Mediterranean Sea were sampled using a bottom otter trawl during the DESEAS oceanographic survey carried out from early June to early July 2001, covering an area in the western Mediterranean from 600 to 2800 in in depth and two areas in the central Mediterranean, the western and eastern Ionian Sea from 600 to 4000 m in depth.The sampling was conducted with the otter trawl Maireta System (OTMS) using the R/V García del Cid (38 m long; 1500 HP). The OTMS (vertical opening 1.8-2 m; wing spread 14 m) was trawled by a single warp and operated with a pair of rectangular iron otter boards (1.20 x 2.0 m; 450 kg). A detailed description of the net can be found in Sardà et al. (1998). The initial and final tow time were measured using a SCANMAR sonar system down to 1500 m, and the same parameters were assumed below 1500 m. The vessel speed and geographic position were measured using differential GPS. The trawling was carried out during daylight hours.Temperature and salinity profiles were obtained at each haul using a CTD
