SCAN-2001 Cruise (29HE20001207) carried out on the Research Vessel Hespérides in 2000, Geodynamics of the Scotia plate edge / Antarctic and Antarctic Deep Water paleoceanography. The project and the 2001 SCAN campaign focus on the analysis of areas that comprise the boundary between the Antarctic and Scotia plates. The basic objectives are oriented to the analysis of continental fragmentation processes and the creation of oceanographic basins. The thematic aspects include the geodynamic, petrological and seismic stratigraphy study of directional large faults, the development of backarc ocean basins, the creation of continental blocks and the paleoceanographic analysis on the evolution of Deep Antarctic Water. Special attention is paid to the establishment of the geological processes that take place at the edges of the plates. The aim is to distinguish between the factors linked to local phenomena (tectonic, sedimentary contribution) and those of a global nature (climatic-eustatic change, glacial cycles) which have controlled the paleoceanographic processes and the development of the various depositional provinces

ICEFISH Cruise (29HE20010119) carried out on the Research Vessel Hespérides in 2001, Physiological adaptations of fish in ice (Channichtyidae family) during development, with special reference to the expression and activity of the inducible form of nitric oxide synthase (NOS) .The objective of the campaign is to capture larvae of ice fish to determine: 1) The different isoforms of nitric oxide synthases, the level of protein and mRNA, as mollecular markers of hyperoxia.2) The stage of larval development by allocating the age by otolith analysis and RNA / DNA rates. 3) determine the oxygen consumption under controlled conditions

FICARAM-II Cruise (29HE20010305) carried out on the Research Vessel Hespérides in 2001, 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 column

GOLFO Cruise (29HE20010514) carried out on the Research Vessel Hespérides in 2001, "Dynamic distribution of plankton and seston in the Gulf of Cadiz: scales of variability and control by physical and biological processes"GOLFO. The main objective is to know the variability in the distribution of plankton and seston in the Gulf of Cadiz in relation to the oceanographic processes that affect the basin. The project is divided into 3 subprojects. 1) Study the circulation and distribution of water masses and physical processes in this region. 2) Study the spatial variability of phytoplankton and seston as well as the control scales by physical and biological processes. 3) Study the spatial variability of the picoplankton and zooplankton fractions in this region of the Gulf of Cadiz

ZEE-2001 Cruise (29HE20010801) carried out on the Research Vessel Hespérides in 2001, Exclusive Economic Zone cruise 2001

HITS Cruise (29HE20010907) carried out on the Research Vessel Hespérides in 2001, Characterization of tsunamigenic structures in SW Iberia margin by Side Sonar TOBI. High resoultion imaging of tsunamigenic Structures in the southwest Iberian margin (Hits). The HITS campaign has been designed to determine the detailed geometry of the active seismogenic structures of the South West of the Iberian Peninsula using the TOBI high resolution sonar. In addition, to calculate the style and movement of active faults, as well as recurrence rates, the sampling and subsequent dating of the units associated with the seismic cycle of the fault is necessary, for example the landslides located at the base of the escarpment. For this purpose, we forecast the realization of several gravity cores in areas previously identified by TOBI, corroborated by multibeam. echosounder and parametric probe. Finally, to determine the possible factors that may influence the nucleation and propagation of earthquake ruptures, we plan to investigate the thermal regime of the fault zone by means of the heat flow probe and its possible escape of fluids, by means of a nephelometer / underwater camera SHRIMP

FICARAM-III Cruise (29HE20011028) carried out on the Research Vessel Hespérides in 2001, The overall objective of the FICARAM program is the annual monitoring and evolution of the quantification of CO2 uptake in the Atlantic. The specific objective of the Ficaram III campaign is to evaluate the air-sea exchange of carbon dioxide, measuring the partial pressure of CO2 in the surface of the sea and in the atmosphere. Also salinity and temperature will be measured, chlorophyll by fluorescence, meteorological variables (wind, atmospheric pressure, air temperature and geographical position

COHIMAR Cruise (29HE20011206) carried out on the Research Vessel Hespérides in 2001, Ice streams and glacial-marine sedimentary systems of the Pacific margin of the Atlantic peninsula (COHIMAR). Precise location and cartography of the ice anchoring lines "grounding line" and of the furrows and deposits resulting from the action of the ice streams that occupied the Pacific margin of the Antarctic Peninsula in the glacial peaks, and especially in the Ultimate Maximum Glacier. The investigation will extend to the distal margin of the most interesting sectors
