BUSCADOR RECOLECTA

GEODEC-MAR Cruise (29HE20020123) carried out on the Research Vessel Hespérides in 2002, Study of Deception Island volcanic complex and its environment from marine geophysical techniques. Partial objectives: - Establishment of models of horizontal and vertical deformation. - Determination of a local geoid. - Analysis of maps of geomagnetic and gravimetric anomalies. - Establishment of a model of the structure of the crust and upper part of the mantle. - Numerical modeling of behavior. of the boilers. - Elaboration of statistical models for the calculation of the return period. - Elaboration of risk and dangerousness maps. - Elaboration of a multidisciplinary scientific support system (SIMAC). -Geodynamic interpretation of the previous models. SOURPROJECTS: GEODEC-GEODESIA: Geodetic studies on Deception Island. GEODEC-MODELS: Modeling of the active geological processes of the Decepción volcano from the integration of geophysical and geodetic data.GEODEC-GEOMAR: Study of the volcanic complex of Deception Island and its surroundings based on marine geophysics techniques

DRAKE-02 Cruise (29HE20020219) carried out on the Research Vessel Hespérides in 2002, Study of the circulation and bathymetry of the environment of the circumpolar current (DRAKE). Objectives: 1-To study the geographic variations of the differents water masses present in Drake passage, Brandsfield sea and Decepcion Island. 2-To verify the NOAA satellites radiometer formalism comparing in situ measurements simultaneously recorded in the Antartic Ocean and Cadiz Gulf with satellite data. 3-To verify the Topex-Poseidon, ERS-2 altimeters by direct comparation of the geostrophic currents computed from altimetry and local currents simultaneous measurements. 4- To compare satellite altimeter data with gravimeter continous records

FICARAM-IV Cruise (29HE20020304) carried out on the Research Vessel Hespérides in 2002, 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

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
