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.
The ZEE-2001-EZA campaign was part of the program "OCEANOGRAPHIC HYDROGRAPHIC STUDY OF THE EXCLUSIVE SPANISH ECONOMIC ZONE" (PIHOZE), approved by the Council of Ministers, dated April 22, 1993, and carried out by the Hydrographic Institute of the Navy (IHM) and the Spanish Institute of Oceanography (IEO). The ZEE-2001-EZA campaign aimed to carry out the necessary work to obtain the hydrographic-oceanographic knowledge of the eastern part of the Canarian Archipelago, mainly the areas adjacent to the Islands of Fuerteventura and Lanzarote and complete the work carried out during the campaigns Zee-98, Zee-99 and Zee-00, carried out aboard the B.I.O. Hesperides
Study of different sectors of the Mediterranean margins of Andalusia to analyze the potential existing active tectonic structures, capable of generating geological risks either due to the generation of earthquakes, or secondarily due to the triggering of landslides and / or tsunamis.
Bathymetry and seismic work on the coast of the island of Menorca (Baleares Islands)
They focus on the seabed research of Mediterranean sea (Spain ), both indirect and direct. Carry out a survey of the fishing beaches to later elaborate fishing charts. Systematic bathymetric survey of the study areas with 100% coating (Multi-beam echo sounder EM-300). seismic profiles according to the ship's defeat (Topas 710 system). Performance of sound velocity profiles in the water column. Side sweep sonar in selected areas. Sediment sampling (Shipeck dredges - Box corer). Sampling of Rocky Outcrops (Rock Dredge).

LASEA campain from project CGL2011-30302-C02 has the following objectives: Phase 1: Acquire bathymetric and seismic data from the gulf of Cadiz using acoustic echo sounders EM710, TOPAS and Sparker. Phase 2: Obtain sediment samples from the gulf of Cadiz and complementary bathymetric data.
During the ABRIC-3 cruise, the acquisition of high resolution bathymetries of the fishing grounds in Blanes and Palamós submarine canyons have been carried out using the ship hull multibeamm echosounder. Sediment cores have been obtained to determine the rates of sedimentation in the axes of the canyons. TOPAS seismic profiles were also collected crossing the canyon rims and flanks..

To define the Nephrops distribution in the Gulf of Cádiz 3. To obtain density estimates of megafauna species and the occurrence of trawl marks on the sea bed 4. To measure oceanographic variables using a sledge mounted CTD 5. To prospect circalittoral and bathyal areas witihout trawling activity 6. Sea bed morphological and backscatter analyses
