IDEADOS-09 Cruise, RV Sarmiento de Gamboa

IDEADOS-09 Cruise (29SG20091130) carried out on the Research Vessel Sarmiento de Gamboa in 2009Benthopelagic ecosystem structure in the western Mediterranean: a multidisciplinary approach and different time scales in the Balearic Islands.The overall objective is to determine relationships between environmental conditions and nekto-benthic slope communities in two areas of the western Mediterranean, with distinct geomorphologic and hydrodynamic characteristics. Sub- Objectives 1.To determine the effect that seasonal variability of the hydrodynamics has on the species and communities of the slope and on their trophic resources along the water column, by means of the study of the various compartments of the zooplankton (micro-, meso- and macro-zooplankton) and nekton (micro- and macro-nekton). 2. To determine the viability of applying acoustic methods for the characterization of the communities in the Deep Scattering Layers (DSL) of the meso-pelagic domain.3. To determine the influence of the high frequency variability (daily, fortnightly and/or monthly) of the oceanographic conditions on the biology and dynamics of the red shrimp. 4. To contextualize the oligotrophic ecosystems of the Balearic Islands from a global perspective, including adjacent areas of western Mediterranean, from: (i) the estimation of the degree of connectivity between populations of the continental margin of the north-western Mediterranean and the Balearic Islands, using geochemical markers in hake otoliths; and, (ii) the analysis of information from fishing exploitation on the peninsular coast and the archipelag
