ELEFANTE-13 Cruise (29HE20130121) carried out on the Research Vessel Hespérides in 2013, In January 2012, a physical-geological mooring was installed to the East of Elephant Island onboard the RV Hesperides. The mooring was constituted by current meters, temperature, conductivity, and pressure sensors located at selected depths. The mooring was deployed for one year period, and successfully recovered on January 23rd 2013 during the Hesperides Antarctic Survey 2012-2013. The goal of the experiment is to monitor the presence / absence of the Antarctic slope front over the southern slope of the South Scotia Ridge

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

FICARAM-XV Cruise (29HE20130320) carried out on the Research Vessel Hespérides in 2013, FICARAM cruise aims to investigate the evolution of decadal anthropogenic carbon and to evaluate the CO2 uptake capacity in the sector South Atlantic Ocean and its spread to Ecuador and Nord-tropical zone. Another important component of FICARAM cruise aims examine the biological and biogeochemical mechanisms that hinder total dissolved organic carbon (DOC) remineralisation in marine systems, taking a multidisciplinary perspective and applying many different approaches. This objective is the global objective of the Spanish project DOREMI that join this FICARAM cruise. Along the section, the DOREMI project will test the effect of different factors (carbon and nutrient additions, and microbial structure) on DOC degradation in epipelagic, mesopelagic and deep waters, developing some experiments determining the potential degradability of mesopelagic and epipelagic DOM, and the role that labile C supplements plays regulating this process and by the microbial structure

SUBVENT-1 Cruise (29HE20130921) carried out on the Research Vessel Hespérides in 2013, The objective of the SUBVENT-1 cruise is to investigate the evidence of emissions from fluids detected west of the Canary Islands, in the deep zone of the continental margin, where possible acoustic feathers that could have been identified generated by underwater emissions of fluids. The SUBVENT1-0913 cruise has been carried out along the lower slope of the continental margin of the Canary Islands. This area is characterized by the presence of several recent geological structures. Among these are the distal parts of the volcanoclastics debris deposits originated by volcanic avalanches of the Canary Islands, transported by gravity along the slope and probably related in origin to eruptive episodes. In the southern part, numerous and different reliefs (seamounts, hills or mounds) of volcanic origin occur. The most frequents features display heights between 30 and 300 m and they have constituted one of the main aims of this survey. Moreover, in this sector there are several subparallel linear scarps with similar directions to the slope trend that could be associated with the aforementioned mounds. The acquisition of new geophysical data and samples during this cruise will allow a better understanding of the origin of these mounds and the emission processes that have generated them. On the other hand, the knowledge of the relationships between debris and hemipelagic sediments together with those associated with possible venting processes in the area, will reveal not only the sedimentary evolution of this margin, but also to establish emission episodes generating mounds and to know their growth patterns. Furthermore, it would be possible to evaluate the sedimentation rate in the area and the role played by the Antarctic Bottom Water (AABW) mass on this process

SPURS-MIDAS Cruise (29SG20130316) carried out on the Research Vessel Sarmiento de Gamboa in 2013, MIDAS (SMOS ocean salinity and soil moisture products. Improvements and applications demonstration) SPURS experiment (Salinity Processes in the Upper ocean Regional Study). Realization a wide range of mesoscale and submesoscale measurements to contribute understanding the mechanisms of formation and permanence of the largest ocean salinity maximum in the centre of the North Atlantic subtropical gyre. Several standard and prototype instruments are used in measuring sea surface salinity and other ocean variables

BIOCANT-3_LEG1 Cruise (29SG20130424) carried out on the Research Vessel Sarmiento de Gamboa in 2013, The objective of the DOS MARES project is twofold. First, we aim at understanding the effects of the atmospheric teleconnections between the Cantabrian Sea and the north-western Mediterranean Sea, and their impacts on the deep ecosystem, both pelagic and benthic. Second, we want to know in which way the transfer of the signal from the external forcings towards the deep ecosystem controls the community structure and the population dynamics. Thus, in March 2012 we deployed 6 mooring lines equipped with sediment traps and currentmeters in the Avilés and Gaviera canyons and the slope. In September 2012 the moorings were successfully recovered and redeployed again, and during this cruise DOSMARES BIOCANT3 they have been finally recovered and the 1-year monitoring effort finalised. In addition, CTD profiling has been performed to characterise the biological and physical structure of the water column (including the acquisition of discrete water samples), multicorers have been obtained to characterise the geochemical properties of surface sediments, and a multinet used to obtain macro- and meso-zooplankton community structure. Overall, data will allow to characterize the external forcings and abiotic conditions in the Cantabrian Sea, and thus establish the links between abiotic conditions, populations and pelagic and benthopelagic resources
