Salt deformation and sub-salt fluid circulation in the Algero-Balearic abyssal plain(SALTFLU): 1) To identify the three dimensional structure of the salt deformation structures of the Algero-Balearic abyssal plain;2) to collect evidence of fluid migration, accumulation and extrusion at the seafloor; 3) to constrain the link between the observed overburden fluid circulation and deep (sub-salt) origins; 4) to link the fluid circulation pattern to the recent basin evolution with special regard to the tectonic stress propagation derived from convergence between the Africa and European plates.
1. Estimation de l'abondance de les poissons pélagiques par echointegration de les eaux côtières sud de l'Europe. 2. Cartographie de l'are de distribution. 3. Estimation de la abondance des ouefs par enregistrementg en continue. 4. Etalonnage entre l'enregistrement en continue des ouefs et les classiques estations avec Pairovet. 5. Estimation de la biomasse fractionée (Mèthode CHN) de plankton. 6.Etude de les conditions oceanographiques et méteorologiques et sa rélation avec la distribution et abondance des oeufs et adultes des poissons pélagiques. 7. Hydrologie: Charactesisation des propietés termohalines des eaux sur le plateau continental. Mesure de profiles verticales de température, salinité et fluorescende dans des stations et acquisition de données de surface (thermosalinometrie, fluorescence, métèorologie). 8. Placton: Détermination des patrons de distribution de la diversité taxonomique et de la biomasse en différent classes de taille du plancton (phyto et zooplancton) dans la zone d'étude. 9. Cartographie de l'abondance des prédateurs
Campaign to obtain samples of mud mullets (Mullus barbatus) and sediment. The objective is to evaluate the temporal trends of priority chemical pollutants and the study of the biological effects of pollution.
Obtain abundance indexes of lobster (Palinuros elephas) inside and outside the protected area of the Cala Ratjada Marine Reserve, carry out experimental plankton fisheries in order to obtain philosophical larvae of the different species of lobster present in the study area, and install and maintain lobster post-larval collectors in the coastal area (<25m) and deep (> 60m)
Perform an acoustic evaluation by vertical eco-integration of the recruitment of small pelagic species, their mapping and that of the oceanographic and biological conditions prevailing in the recruitment areas.
Cartographic survey, obtaining seismic profiles and knowledge of the nature of the fund from high-resolution geophysical techniques (multi-beam and parametric probes and the use of dredgers.
Monitoring of eutrophication. Water and phytoplankton samples were taken to study the phytochemical and biological characteristics of the water column.
Estimation by pelagic trawling and acoustic methods of the biomass index and population and biological parameters of anchovy (Palinorus encrasicolus) and (Sardine pilchardus sardine as a secondary objective) to assess the state of the fisheries. In the pelagic trawling, the Daily Egg Production Method (MPDH) is applied as biomass estimation. Study of the influence of the hydrographic variables of the water column (temperature, salinity and chlorophyll).
Study of the Spanish continental shelf. Cartographic survey, obtaining seismic profiles and knowledge of the nature of the fund from high-resolution geophysical techniques using dredgers
To collect relevant information to evaluate The levels of eutrophication in the coastal strip between Algeciras and Barcelona (Iberian coast, Alborán Sea and NW Mediterranean).
