BUSCADOR RECOLECTA

LATITUD-III Cruise (29HE19991101) carried out on the Research Vessel Hespérides in 1999, Latitudinal patterns in regulation of the oceanic plankton production. Latitudinal patterns in regulation of the oceanic plankton production . The objective of the campaign is to study the variation of growth and mortality of the photosynthetic plankton cells throughout the different oceanographic zones of the Central Atlantic, with special interest in tropical gyres (or oceanic deserts) where the conditions are extreme for these organisms. During the study, techniques will be applied for the first time to identify necrotic and apoptopic cells (the two described processes of cell death) in marine phytoplankton, processes that have only been observed in the laboratory. The cell death of photosynthetic plankton is a process unknown until recently, which has important consequences for the oceanic carbon cycle

DECVOL Cruise (29HE19991203) carried out on the Research Vessel Hespérides in 1999, A seismic network was deployed along the interior coast of Deception Island in order to establish a rapid assessment of the level of seismic activity on the island. This objective is focused on observing and checking if the seismic crisis that occurred during the months of January and February of 1999 was still present

CIEMAR Cruise (29HE19991212) carried out on the Research Vessel Hespérides in 1999, Oceanographic campaign composed of different phases according to the geographical area of ​​study (Drake Triangle, Bellingshausen Sea, Bransfield Strait, Gerlache Strait, O'Higgins) The main objectives.1) Modulation of the planktonic distribution by hydrographic conditions . 2) Bentos larval strategies. 3) Mixing processes in frontal regions and modulation of biological production. 4) Establishment of the level of non-movement in the Drake Strait and balance of flows. 5) Thermal structure in the Drake Strait

ESEPAC-2 Cruise (29HE20000116) carried out on the Research Vessel Hespérides in 2000, Experimental Stimulation of Coastal Antarctic Production. The objective of the ESEPAC-2000 campaign is to recognize the factors that limit Antarctic plankton production in order to predict changes in carbon fluxes associated with changes in Antarctic plankton production. The achievement of this objective will be carried out through: 1) Experimental verification of the processes that regulate the production of plankton, through large-scale manipulation experiments in mesocosms (large incubation bags, 30000-50000 liters). 2) The comparison of the experimentally obtained predictions with observations of the planktonic dynamics in Antarctic waters of contrasting areas, by means of oceanographic sampling in diverse zones of the Antarctic Peninsula

LATITUD-IV Cruise (29HE20000317) carried out on the Research Vessel Hespérides in 2000, Latitudinal patterns in regulation of the oceanic plankton production . The objective of the campaign is to study the variation of growth and mortality of the photosynthetic plankton cells throughout the different aoceanographic zones of the Central Atlantic, with special interest in tropical gyres (or oceanic deserts) where the conditions are extreme for these organisms. During the study, techniques will be applied for the first time to identify necrotic and apoptopic cells (the two described processes of cell death) in marine phytoplankton, processes that have only been observed in the laboratory.

TASYO Cruise (29HE20000425) carried out on the Research Vessel Hespérides in 2000, Tecto-sedimentary transport from the continental margin of the Gulf of Cadiz to the Atlantic abyssal plains . The present project focuses on the geodynamic, stratigraphic and morpho-sedimentary study of the continental margin of the Gulf of Cadiz and its relationship with adjacent abyssal areas. It is intended to determine the tecto-sedimentary transport between the platform-slope of the Gulf of Cadiz and the abyssal plains of Herradura and Sena. The area is of special importance because it is very conditioned by one of the most gigantic phenomena of submarine sedimentary transport that can be known both in the Atlantic and in other oceanic areas of the world. This is due to a substrate in the sedimentary basin characterized by an olistostromica mass that conditions a high tectonic and sedimentary instability from the Mieocene to the present day

PARSIFAL Cruise (29HE20000518) carried out on the Research Vessel Hespérides in 2000, Seismotectonics parameterization of the fracturing of the Atlantic margin of SW Iberia: Application of seismogenic models of tsunamis. General objective: Modeling of an active seismogenic area capable of causing large tsunamis of great social and environmental impact. Specific objectives 1) Definition of the structural, morphological and neotectonic style of the south west margin of the Iberian Peninsula by sampling sedimentary rocks (gravity corer), high resolution bathymetric cartography and reflectivity images (echographies) of the seabed. 2) Tectonic characterization of the contact between the Iberian and African plates. For this, active and passive seismic will be carried out to obtain geophysical parameters, which allow the modeling of the entire southern Atlantic margin, Peer reviewed

TECALB Cruise (29HE20000819) carried out on the Research Vessel Hespérides in 2000, Tectonics, structure and morphology of the Alboran Sea and South Balearic Basins and Margins : Acquisition of multi-channel reflection seismic data, seismic refraction / reflection velocities, magnetism, gravity and multibeam probes aboard the BIO Hesperides

EMI Cruise (29HE20001025) carried out on the Research Vessel Hespérides in 2000, Measurement of electromagnetic emissions in the research vessel HESPERIDES and developing a distribution map of the disturbances

FICARAM-I Cruise (29HE20001030) carried out on the Research Vessel Hespérides in 2000, The overall objective of the FICARAM program is the monitoring and the annual evolution of the quantification of CO2 uptake in the Atlantic. Specific objectives during the campaign: 1) Evaluate the air-sea exchange of carbon dioxide, measuring the partial pressure of CO2 on the surface of the sea and the atmosphere. 2) Estimate the incorporation of anthropogenic carbon, measuring the variables of the carbon system (pH and alkalinity) and dissolved oxygen in the water colum
