TEIDE-95 Cruise (29HE19950415) carried out on the Research Vessel Hespérides in 1995, Study morphotectonic submarine flank of Teide. Among the specific objectives of this Project are the knowledge of the morphology of the seabed, the seismic characterization and quantification of pyroclastic materials and understanding of the origin and evolution of the Orotova, Icod and Güimar valleys. For the resolution of the previous objectives, a set of geophysical techniques has been applied among which are included: Magnetometry, Gravimetry, seismic reflection and multibeam echosounders

VARIMED-95 Cruise (29HE19950602) carried out on the Research Vessel Hespérides in 1995, Mediterranean pelagic ecosystem study: analysis of plankton dynamics. The main objectives are the study of the temporal variability of high frequency (hours) and medium (days, weeks) of the physical and biological phenomena that determine the transfer of matter and energy in the pelagic system (classic trophic networks, based on phytoplankton < herbivore zooplankton < fishes, or microbial networks, based on Phytoplankton < bacteria < flagellates and ciliates< zooplankton < fish. Several in situ experiments have been conducted

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.

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.
