MALASPINA_LEG6 Cruise (29HE20110513) carried out on the Research Vessel Hespérides in 2011, A circumnavigation oceanographic expedition to generate a high resolution inventory of global change impact on the ecosystem of the ocean, researching its biodiversity in the deep. 1) PHYSICAL OCEANOGRAPHY: The main objective of the Physical Oceanography block is to contribute to understanding the oceanic variability by determining the trends of the different properties of the main bodies of water in the oceans, such as temperature, salinity and oxygen concentration, thus will allow us to determine the variation of atmospheric conditions. 2) BIOCHEMISTRY: The MALASPINA 2010 expedition will study on an unprecedented scale the biogeochemical processes in the ocean on a global scale. It will be investigated where the elements that contribute to life near the surface come from, and what is the fate of the organic matter generated by photosynthesis . The breath of the sea will be measured: the exhalation of gases that conditions our atmosphere and climate. 3) ATMOSPHERIC DEPOSITION: The objectives of block : "organic pollutants and atmospheric deposition" focus on the measurements of the levels of several families of organic pollutants in the global ocean and atmosphere and the quantification of air-ocean flows and their impact on food chains planktonics (phytoplankton and zooplankton). In addition, a characterization and quantification of the flows of organic carbon, aerosols, nutrients and organic biogenic compounds, and the role they play in the ocean biogeochemical cycles will also be carried out. 4) OCEAN OPTICS: In the Malaspina expedition we are going to study the optics of the ocean that involves measuring mainly the color of water and its transparency to solar radiation. 5) BIODIVERSITY AND MICROBIAL PROCESSES: Our main objective is to investigate, to know, what microorganisms are found and how they are acting in the different oceans of the planet, placing special emphasis on the vast and practically unknown deep ocean. 6) ZOOPLANKTON: The objective of this thematic block is to assess the diversity and efficiency of the energy transfer of the ocean zooplankton community on a global scale. 7)PHYTOPLANKTON AND BIOLOGICAL PRODUCTION: Quantify how solar radiation is transmitted through the water column. The behavior of the photosynthetically active light band, which includes visible light of wavelengths between 400 and 700, and of bands of light in the ultraviolet zone will be studied separately. Quantify the magnitude of the organic matter (in particulate and dissolved form) synthesized by the photosynthetic phytoplankton (the so-called primary production or PP), Quantify the carbon consumed by the respiration of the pelagic community, from the surface to the deepest levels of the water column) and compare it with the PP of the different areas visited, - Study the structure of sizes and the distribution by groups of the phytoplankton communities, Evaluate how phytoplankton growth rates vary in response to changes in PAR intensity, ultraviolet radiation and temperature, Estimate the losses due to cell death 8) POPULAR SCIENCE: The Malaspina project has among its objectives to inform society about the impact of global change on the ocean and new opportunities to explore marine biodiversity, increase social awareness of the original Malaspina expedition and encourage scientific vocations among young people 9) STUDENT TRAINING: The Malaspina 2010 project aims to promote scientific vocations among our young people by providing a highly visible activity that will combine aspects of frontier research with an adventure component and attractive teamwork as a training framework. Six universities (U. de Barcelona, ​​U. de Granada, U. de Oviedo, U. de Cádiz, U. Las Palmas de Gran Canaria and U.

ELEFANTE-12 Cruise (29HE20120119) carried out on the Research Vessel Hespérides in 2012, A physical-geological mooring is installed at the East of Elephant Island in order to monitor the presence / absence of the Antarctic slope front on the south slope of the South Scotia Sea, and to study its role in the modification of intermediate waters of the Antarctic Circumpolar Current. The addition of a sediment trap will study the flow of sediments associated with the dynamics of the area and identify terrigenous and biogenic composition. 1) Placement of an anchor constituted by current meters and temperature sensors, salinity and pressure at different depths, in addition to a sediment trap placed near the bottom. The anchor has a length of about 700 m and can be installed on a background of about 1200 m. 2 )Completion of several transects for water sampling using CTD. The purpose of these transects is to calibrate the anchored instruments and carry out a hydrographic survey of the slope front and the southern border of the circumpolar current at the moment of anchoring. The CTDs will be made to the bottom

SCAN-2013_CODEREC Cruise (29HE20130202) carried out on the Research Vessel Hespérides in 2013, SCAN 2013 ( SCotia-ANtarctic) & 'Lithological and chronostratigraphic study of recent sedimentary units of Puerto Foster (Deception Island, Antarctica), COREDEC ' During the 2013 SCAN cruise, two basic objectives related to the evolution of the Western Antarctica: (a) plate tectonics and the development of ocean basins in the Scotia Sea and Straits of Brandsfield, and (b) the paleoceanographic processes that were derived from the establishment of the Circumpolar Current Antarctic (ACC) after the opening of the Drake Passage and the development of Antarctic Deep Water, with its implications and possible contribution to global change. High resolution (SAR) seismic reflection profiles, very high resolution seismic profiles have been made using the TOPAS system, EM 120 multibeam echo sounder, magnetometry and gravimetry in the Scotia Sea and Strait of Brandsfield. 17 SAR profiles have been obtained, with all operating systems with a total of 2679.4 km. They have made a total of 47 lines with TOPAS, MAG and GRAV, along a route of 5,025 km. They have dredged, in addition, 5 morphological reliefs and 3 gravity witnesses have been taken in 1 high with outcropping series. The dredges carried out have provided excellent quality samples of the igneous and metamorphic basement of the Scotia Sea. The objective of CODEREC has been to obtain Seven sediment cores from the inner bay of Deception Island

DETSUFA Cruise (29HE20130304) carried out on the Research Vessel Hespérides in 2013, The objectives of the DETSUFA cruise (BIO Hespérides 04/03–17/03/2013) are (1) to evaluate the footprint in the seafloor of a series of earthquake-generated subaerial landslides that took place in Fiordo de Aysén, Chile, in 2007, which entered the seawater generating a number of destructive tsunamis which killed 10 and produced significant damage in the local infrastructure, (2) to reconstruct the morphology and dynamics of these landslides in order to obtain input data for tsunami modelling, and (3) to determine the occurrence of similar episodes in the past that might have generated other tsunamis, in order to establish a possible recurrence period of such events. The cruise fits within the global scientific interest stirred up by tsunamis in general, being the Fiordo de Aysén a highly relevant analogue for the understanding of this kind of events occurring in semi-enclosed basins such as fjords, lakes or water dams, which often harbour large human population and infrastructures
