BUSCADOR RECOLECTA

Two onshore profiles were acquired in E-W and N-S directions through the Variscan and Alpine domains of 140 and 65 km length, ESCI-N1 and ESCI-N2 respectively. Also two offshore profiles ESCI-N3 and ESCI-N4 were obtained with a streamer of 4500 m having 360 channels with a 12.5 m gap between them and a 40 l airgun capacity. ESCI-N3 follows a swerved line in a mainly E-W direction crossing the Variscan structures. ESCI-N4 is a N-S direction profile that crosses both the Cantabrian margin and Le Danois bank Alpine structures. Techincal specifications of offshore profiles: streamer length 4,500 m, 360 channels, group interval 12,5 m and sample rate 4 ms., The ESCI-N project in Northwestern Spain was a subprogram of the ESCI Program (Estudios Sísmicos de la Corteza Ibérica). It is formed by four seismic experiments both on and offshore. This project aimed to image the Cantabrian Zone, West Asturian-Leonese Zone and the northern Iberian margin, thus characterizing the crustal structure resulted from the Variscan and Alpine orogenies and the Mesozoic extension related to the opening of the Bay of Biscay., CICYT (Committee of Science and Technology of the Spanish Ministry of Education and Science), GEO90-0660.-- FICYT (Fundación para el Fomento en Asturias de la Investigación Científica Aplicada y la Tecnología).-- Science and Technology for Regional Innovation and Development in Europe-European Commission, Peer reviewed

Two land seismic profiles across the Betic Chain imaged the deep structure of the crust belonging to two different crustal domains. To the north, one profile samples the crust of the Variscan Iberian Massif that underlies the sedimentary cover of both the Guadalquivir foreland basin and the South Iberian crustal domain. A second profile crosses the Alpine metamorphic complexes of the Betics., Comisión Interministerial de Ciencia y Tecnología - CICYT.-- Dirección General de Investigación Científica y Técnica - DGICYT.--, Peer reviewed

Complete the optical, biological and hydrographic characterization of the massive flowering of microalgae in the Patagonian coasts; understand the relationships between the conditions of the Malvinas Current and the generation of massive flowering; and develop and validate specific algorithms for the determination of pigments (responsible for red tides) from satellite

TRYNITOP-2 Cruise (29HE20080408) carried out on the Research Vessel Hespérides in 2008, Trynitrop ('Trichodesmium and N2 fixation in the tropical Atlantic). The objective of the TRYNITROP project is to characterize the distribution and activity of Trichodesmium and other N2 fixatives, to determine the factors responsible for the control of N2 fixation as well as the contribution of these organisms to the fluxes of C and N mediated by the microbial plankton in the Phototic layer of the Tropical Atlantic. The project will be carried out between latitudes 35º N and 35º S, in the longitude 028º W

MVSEIS Cruise (29HE20080516) carried out on the Research Vessel Hespérides in 2008, MVSEIS: Tectonic control, deep structure and the mud volcanoes of the Gulf of Cádiz characteristics. The main scientific objectives of the MVSEIS campaign can be summarized as follows: 1) Study the morphology and the internal geophysical configuration (seismic, magnetic and gravimetric) of the mud volcanoes and carbonate diapiric dorsal continental margins of the Gulf of Cádiz. 2) Identify, sample and photograph possible active structures of emissions of Fluids in the bottoms of diapiric ridges and mud volcanoes. 3) Sample gas hydrates associated with mud volcanoes and study the geothermal and oceanographic conditions for its formation. 4) Identify and sample biomineralizations (nodules, crusts, chimneys, etc.) by the action of micro / macro chemosynthetic organisms by anaerobic oxidation of methane and / or dissociation of hydrated gases (clathrates). 5) Recognize the role of global (paleo) oceanographic / climatic changes and tectonics in the formation and evolution of mud volcanoes, diapiric ridges carbonated, deep chemosynthetic reefs and associated biomineralisations
