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
