FICARAM-V CRUISE, RV HESPÉRIDES

  • Ríos, Aida F.
  • CSIC - Unidad de Tecnología Marina (UTM)
FICARAM-V Cruise (29HE20021028) carried out on the Research Vessel Hespérides in 2002, The specific objective during the FICARAM V campaign is to evaluate the air-sea exchange of carbon dioxide, measuring the partial pressure of CO2 from the sea surface and in the atmosphere. This campaign is framed in the European project "CAVASSOO" (Carbon variability by ships of Opportunity). Salinity-temperature, chlorophyll by fluorescence and meteorological variables (wind, atmospheric pressure, air temperature and geographic position) will also be measured. The study will be conducted in the Cartagena-Rio de Janeiro section

TEMPANO CRUISE, RV HESPÉRIDES

  • Vaqué, Dolors
  • CSIC - Unidad de Tecnología Marina (UTM)
TEMPANO Cruise (29HE20021123) carried out on the Research Vessel Hespérides in 2002, The main objective of the project is to quantify experimentally how temperature affects the regulation of metabolic processes and possible changes in the structure of Antarctic planktonic communities and the implications this implies globally. These communities are composed of unicellular microorganisms that have sizes from less than 1 micron in diameter (bacterioplankton and archaea) to a few tens of microns (phytoplankton and protozoa) and multicellular organisms such as zooplankton (small crustaceans, krill). Phytoplankton are constituted by photosynthetic organisms, whereas bacterioplankton, protozoa (ciliates and flagellates) and zooplankton are mostly heterotrophs (consumers of organic matter, either dissolved and particulate). Part of this matter is breathed and returned to the environment in the form of CO2. The mere fact that the water temperature will increase 0.5 and 1 degree in an extreme system such as Antarctica will likely result in increased respiration (CO2 excretion) by heterotrophic organisms which, in part, could be fixed by phytoplankton. , or in the worst case, it could be released into the atmosphere, promoting the greenhouse effect and the global warming of the planet. Experiments related to primary production and temperature and light have been carried out

BREDDIES CRUISE, RV HESPÉRIDES

  • Sangrà, Pablo
  • CSIC - Unidad de Tecnología Marina (UTM)
BREDDIES Cruise (29HE20021227) carried out on the Research Vessel Hespérides in 2002, Mesoscale vortices/meanders in the central portion of the Bransfield Strait: identification and physical–biological coupling-BREDDIES. The general objective of this project is their identification and the study of the coupling between the underlying physical processes and the plankton community. With this aim an interdisciplinary sampling was conducted in the region, with spatial resolution and a degree of interdisciplinary interaction not previously carried on. Through the observations we aim at gaining a better physical and biological characterization of these structures as well as understanding the adjustment mechanisms between the physical processes (water column stability, diapycnal mixing, advection) and the planktonic community (abundance and structure). Additionally we will develop a physical-biological model that allows us to understand and diagnose the nature of such coupling. In this way the results of this project could contribute to the identification of mesoscale structures not previously described and to a better understanding of the adjustment between the planktonic community and the physical environment in the marine antarctic system at the mesoscale range

RG1 CRUISE, RV HESPÉRIDES

  • Ercilla, Gemma
  • CSIC - Unidad de Tecnología Marina (UTM)
RG1 Cruise (29HE20030619) carried out on the Research Vessel Hespérides in 2003, The purpose of the Special Action is to identify and assess the geo-environmental risks in the sinking area of ​​the Prestige vessel, through the integrated study of morphology, stratigraphy and sedimentary facies, bottom types, tectonic structures, fluid migration, seismicity and physical properties. geochemical and geotechnical features that characterize the sediment of the bottom and sub-seabed; It also has the purpose of determining the possible contamination by the fuel of the sea bottom and sub-fund and the geochemical processes acting in said area in order to assess the environmental impact. Before the activity that is going to be carried out on the wrecks, a study like the present one is fundamental, which will allow to know the characteristics of the seabed that this activity has to support and the possible impact that can be exerted on the environment and the interaction resulting between the marine environment and the activity carried out. The institutions participating in the study are: Institute of Marine Sciences (ICM-CSIC), Marine Technology Unit (UTM-CSIC), University of Vigo, University of Cádiz, Geological and Mining Institute of Spain, University of Barcelona, ​​Institute of Sciences of the Earth Jaime Almera (ICTJA-CSIC) and Universidad Complutense de Madrid. The results of this study will be transferable in the short term to the sectors of Government, Industry, Civil Defense and Insurance Companies, to organize what are called prevention and preparation activities, and will help to establish the technical conditions to increase the safety of persons and civil works that may be affected by the Prestige ship spill. The work methodology consisted in the study of bathymetric data obtained with the multibeam probe system EM-12, profiles of high seismic (air cannons) and very high (TOPAS) resolution, and sediment cores of up to 4 m length obtained in three campaigns carried out aboard the ship Hespérides. Various analyzes have been carried out on the sediment samples and include the following types: granulometric analysis, analysis of sand fraction components, determination of carbonate content, X-ray analysis, analysis of physical properties (P waves, magnetic susceptibility, natural radioactivity). ), optical petrographic study -SEM, TEM, DRX-, elemental analysis, organic constituents and radiometric dates. Likewise, seismic networks were installed on land and sea. In the land campaigns (March to October) a terrestrial earthquake intervention network has been deployed in the NW Peninsular, in the area between Ferrol and Vila Nova de Gaia in Portugal. A total of 12 portable stations have been set up to supplement the registration stations with respect to the existing ones permanently, belonging to the national network operated by the National Geographic Institute. On the other hand, to control the local seismic activity around the Prestige, a network of 10 ocean-floor seismometers (OBS) was installed around the wrecks, which remained anchored for almost a month
