Oceanographic campaign taking advantage in transit from BIO Hesperides to Antarctica, Mainly experiments have been conducted in the radioactive laboratory

MAYC-95 Cruise (29HE19951004) carried out on the Research Vessel Hespérides in 1995, Continental margin and deep basins: sedimentary record variable. During the campaign of October 1995 two types of scientific activities have been carried out: 1) Physical oceanography studies in transit between Cartagena and Las Palmas de Gran Canaria: 10 CTD stations up to 1000 m and 70 XBT stations up to 800 m. Continuous measurements with thermosalinograph and currents with ADCP. The salinity of the samples was calculated with the autosal. 2) Studies of marine geology on the continental margin of Agadir and the Agadir basin (Morocco): 13 seismic profiles of air cannons and TOPAS system, 3 EM-2 echosounder profiles, 13 gravimetric and magnetometric profiles. The different techniques used have allowed the morphological and seismic recognition of the system formed by the continental margin of Agadir and the Agadir Basin in order to quantify the transfer of sediments from the mainland to the Agadir Basin and to establish the chronology of the important events sedimentary

FRUELA-95 Cruise (29HE19951203) carried out on the Research Vessel Hespérides in 1995, Carbon flow high productivity area: the western basin of the Bransfield Strait and Gerlache Strait, Antarctica. The FRUELA project is a Spanish contribution to the JGOFS program and its main objective is the cauntering of carbon fluxes in an area of ​​high productivity of the Antarctic Ocean. Concrete goals. A) The determination of the abundances of the main groups of organisms (bacteria, phytoplankton, zooplankton, etc ...) involved in the transfer of organic matter and the concentrations of the main chemical compounds involved. B) the estimation of 1) the amounts of organic matter synthesized by phytoplankton (primary production) and transferred against the various groups of organisms. 2) the amount of organic matter breathed and 3) the amount of organic matter that escapes from the upper parts of the water column and sediments to the bottom, Peer reviewed

FRUELA-96 Cruise (29HE19960118) carried out on the Research Vessel Hespérides in 1996, Carbon flow high productivity area: the western basin of the Bransfield Strait and Gerlache Strait, Antarctica. The FRUELA project is a Spanish contribution to the JGOFS program and its main objective is the cauntering of carbon fluxes in an area of ​​high productivity of the Antarctic Ocean. Concrete goals. A) The determination of the abundances of the main groups of organisms (bacteria, phytoplankton, zooplankton, etc ...) involved in the transfer of organic matter and the concentrations of the main chemical compounds involved. B) the estimation of 1) the amounts of organic matter synthesized by phytoplankton (primary production) and transferred against the various groups of organisms. 2) the amount of organic matter breathed and 3) the amount of organic matter that escapes from the upper parts of the water column and sediments to the bottom. 4) the temporal evolution (last decades) of the accumulation of carbon in the sediments, as a record of the accumulated in different areas of the ocean

DRAKE-96 Cruise (29HE19960214) carried out on the Research Vessel Hespérides in 1996, Spanish contribution to WOCE project. The main objective was to occupy section SR1b (Burdwood Bank - Elephant Island) to obtain variable profiles in 21 oceanographic stations as well as during navigation (temperature, salinity and fluorescence) and current profiles with ADCP. For the stations, CTD has been used with temperature sensors, salinity, dissolved oxygen, fluorescence and light transmission

PALEOPAC Cruise (29HE19960309) carried out on the Research Vessel Hespérides in 1996, The PALEOPAC campaign was developed in the South Pacific in March 1996. During the campaign, kasten cores, gravity corers, maxicores, bathymetric profile with EK 500 and EM 12 probe and very high resolution profiles with BPS parametric probe were taken. The concrete areas of the study have been the southern Chilean margin around the Gulf of Penas, the "sea mounts" located in the basins off the Chilean continental margin and the Nazca Ridge. The intensive zone of work and sampling has been the Nazca Ridge. The purpose of the campaign has been to take cores in areas of the Pacific that allowed to study the paleoceanographic variability from the record of indicators of paleotemperatures and paleoproductivities accumulated in the sediment. The analysis of parameters such as the biogenic opaline, the content of organic matter and certain radioisotopes make it possible to reconstruct the records of paleoproductivity, paleotemperature and ocean circulation during periods of hundreds of kiloyears.

GALAPAGOS-96 Cruise (29HE19960328) carried out on the Research Vessel Hespérides in 1996, Geophysical Campaign to the North of the Galapagos archipelago in the Cocos-Nazca dorsal (Galapagos 96). The main objective of this research is to determine the morphological structure of the COCOS-NAZCA dorsal, using gravity, magnetism and high resolution bathymetry data, which allows us to check the hotspot-dorsal interaction models and quantify the effect of the variation in the contribution of magma to axial morphology and cortical accretion processes in expansion zones with intermediate velocities. Specifically we intend to determine how the axial morphology varies along the ridge as a function of the distance to the Galapagos hotspot. In addition, to restrict the magnitude of variations in cortical thickness associated with the Galapagos "swell" and the changes observed in the axial morphology of the COCOS-NAZCA dorsal

CORTES-96 Cruise (29HE19960412) carried out on the Research Vessel Hespérides in 1996, Crustal Offshore Research Transect from Extensive Seismic (CORTES), The CORTES-P96 multisciplinary experiment was carried out longitudinally and perpendicularly to the Gulf of California or Mar de Cortés. More than 1500 miles of reflection seismic, potential field measurements (gravity and magnetism) over 2000 miles were acquired, as well as side-scan echo sounder and sonographs throughout the cruise. The objective was to solve the complex geodynamics of the Gulf of California covering the most significant structures (fracture zones, oceanic ridges and continental remnant blocks) related to the San Andres-Gulf of California transforming fault system. In addition, the limits between Plate Cocos, Rivera, Pacifico and North America were sampled
