S. ; Knudsen, Per ; Vermeer, Martin ; Andreu, M. A. ; Simó, C. | Instituto de Astronomía y Geodesia (IAG-CSIC-UCM) | 1992GEOMED is a project for the determination of the geoid and of the Sea Surface Topography in the Mediterranean Sea. The existing set of data available on the Mediterranean in already quite significant and it is going to be improved in these years[...]texto impreso
Camacho, A.G. ; Montesinos, F. G. ; Vieira, Ricardo ; Arnoso, José | Blackwell Publishing Ltd | 2001The application of a gravity inversion method enables us to obtain a 3-D density contrast model of the upper crustal anomalies of the volcanic island of Lanzarote (Canary Islands). For this, we use a network of 296 gravity stations distributed o[...]texto impreso
Vieira, Ricardo ; Toro y Llaca, Carmen de | Instituto de Astronomía y Geodesia (IAG-CSIC-UCM) | 1988El gravímetro Askania GS-15 nQ 212 fue transformado en instrumento de cero, es decir de masa estática, en 1979; desde entonces su funcionamiento ha sido contínuo y los resultados de los análisis efectuados de las series observadas han demostrado[...]texto impreso
The method suggests to use a sophisticated scheme for the approximation of the drift of the tidal records. The drift is represented separately in subintervals of the record through polynomials of a variable power. An optimum power is estimated f[...]texto impreso

Vieira, Ricardo ; Venedikov, A. P. ; Toro y Llaca, Carmen de ; Arnoso, José | Instituto de Astronomía y Geodesia (IAG-CSIC-UCM) | 1995This paper is a description of a program named NSV for tidal data processing. Despite the considerable volume of the paper, it deals only with the most important elements of NSV, including its practical use. It is not possible to describe everyt[...]texto impreso

Vieira, Ricardo ; Toro y Llaca, Carmen de | Instituto de Astronomía y Geodesia (IAG-CSIC-UCM) | 1992We present in this paper a synthesis of the first stages of modeling the main constituents of the ocean tides in the Mediterranean sea. We have initiated our work with the construction of the M2 harmonic chart for the whole sea. At the present s[...]texto impreso
Toro y Llaca, Carmen de ; Vieira, Ricardo ; Sevilla de Lerma, Miguel Jesús | Politecnico di Milano . Dipartimento di Ingegneria Idraulica, Ambientale e del Rilevamento | 1993In this paper we describe the modellinng of the M2 and S2 constituents for the Western and Central Mediterranean Sea, based on mareographic observations. The evaluation of the time variations of the sea surface topography is also studied in orde[...]texto impreso

Blanco-Montenegro, I. ; Montesinos, F. G. ; Garcia, Alicia ; Vieira, Ricardo ; Villalain, J.J. | American Geophysical Union | 2005The Bouguer and aeromagnetic anomaly maps of Lanzarote show a gravity high and a dipolar magnetic anomaly over the central part of the island, indicating one isolated source. Assuming that the structure responsible for both anomalies is the same[...]texto impreso

Vieira, Ricardo ; Fernández Torres, José ; Toro y Llaca, Carmen de ; Camacho, A.G. | Instituto de Astronomía y Geodesia (IAG-CSIC-UCM) | 1989Since 1987, and as part of the research project that the I.A.G. is carrying out in the Canary Islands, records are obtained of gravimetric and ocean tides, pressure, temperature, etc. on the island of Lanzarote. The structural and geodynamic fea[...]texto impreso

Montesinos, F. G. ; Benavent Merchán, María Teresa ; Vieira, Ricardo ; Arnoso, José | Elsevier Science | 2011-02We hereby present a new Bouguer gravity map of the La Gomera island (Canarian Archipelago), which is analysed and interpreted by means of a 3-dimensional inversion, in order to contribute to the knowledge of the structural setting of this volcan[...]texto impreso
Vieira, Ricardo ; Ruymbeke, M. van. ; Fernández Torres, José ; Arnoso, José ; Toro y Llaca, Carmen de | Instituto de Astronomía y Geodesia (IAG-CSIC-UCM) | 1990Since 1987 and as a past of the research project that is carrying out the Instituto de Astronomía y Geodesia of Madrid in Canary Islands, a geodynamic permanent station is working in Lanzarote Island, the most northerly and easterly of the main [...]texto impreso
Arabelos, D. ; Spatalas, S. D. ; Tziavos, I. N. ; Sevilla de Lerma, Miguel Jesús ; Toro y Llaca, Carmen de ; Vieira, Ricardo | University of Thessaloniki | 1994Two tidal models for the Mediterranean Sea are recently available. From these models tidal heights have been computed and used to correct the altimeter data of the first 10 ERM's of ERS-I. Comparisons of the statistics of the differences between[...]texto impreso
Toro y Llaca, Carmen de ; Vieira, Ricardo ; Sevilla de Lerma, Miguel Jesús | University of Thessaloniki | 1994In order to evaluate the vertical displacement of the Sea Surface Topography due to the ocean tides, we have made the modeling of the four main constituents M2, 52, 01 and Kl for the whole Mediterranean Sea and the local model N2 corresponding t[...]texto impreso
Toro y Llaca, Carmen de ; Vieira, Ricardo | Instituto de Astronomía y Geodesia (IAG-CSIC-UCM) | 1988En marzo de 1986 y dentro del proyecto de investigación de la Red Ibérica de Mareas Terrestres se instaló en la Facultad de Ciencias Geológicas de la Universidad de Oviedo una estación de registro contínuo de la gravedad. Las fuertes perturbacio[...]texto impreso
Venedikov, A. P. ; Vieira, Ricardo ; Toro y Llaca, Carmen de | Real Academia de Ciencias Exactas, Físicas y Naturales | 1993A new method recently developed in Spain is briefly discussed. The method suggests to use a sophisticated scheme for the appproximation of the drift of the tidal records. The drift is represented separately in subintervals of the record through [...]texto impreso
Arnoso, J. ; Montesinos, F. G. ; Vieira, Ricardo ; Bos, M. S. ; Benavent Merchán, María Teresa | Pergamon-Elsevier Science | 2011Gravity tide records from El Hierro, Tenerife and Lanzarote Islands (Canarian Archipelago) have been analyzed and compared to the theoretical body tide model (DDW) of Dehant el al. (1999). The use of more stringent criterion of tidal analysis us[...]
