ZEE-1999 Cruise (29HE19990516) carried out on the Research Vessel Hespérides in 1999, Exclusive Economic Zone Cruise 1999. Hydrographic-Oceanographic research plan of the Spanish Exclusive Economic Zone

FAX Cruise (29HE19990801) carried out on the Research Vessel Hespérides in 1999, Filament and Fluxes (CANIGO). The campaign was carried out in Canarian waters, the main objective was the estimation of the flows of heat, water, salts nutrient and organic material in a filament of the upwelling of Northwest Africa, and to determine the effect of this transport towards oligotrophic waters on the metabolic balance of carbon in the planktonic communities of the Canary region. The specific objectives of the campaign were: 1) Determine the variability and bidimensional structure of the surface fields of temperature, heat of the ocean, nutrients, inorganic carbon and currents, in relation to the filament, during the study period. 2) Determine the three-dimensional structure and field of currents in the upper 300 m of the filament, in order to determine the origin and dynamics of the filament waters. 3) Determine the flow of particulate and dissolved organic matter exported by the filaments from the upwelling to the oceanic waters. 4) Determine the spatial variability of phytoplanktonic phytosynthetic parameters, pigment concentrations and spectral quality of light in the filament region, to allow the development of primary production models on a regional scale. 5) Determine the metabolic balance of microbial communities (community production and respiration) in the transition zone from eutrophic waters to oligotrophic open waters. 6) Observe the langranian displacement field of a body of water along the "jet" of the filament, by means of drifting Argos buoys. 7) Study the evolution of the stratification, vertical shear, concentration of nutrients, productivity and bio-optical parameters in the upper 200 m of the water column, near a drifting buoy that runs along the "jet" of the filament

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
