    Este estudio pretende relacionar los registros (marzo de 2013 a febrero de 2014) de dos mare贸grafos situados en el Puerto de Barcelona y que se han denominado BCN2 y BCN3. El mare贸grafo BCN2 pertenece a la RED de MARe贸grafos de Puertos del Estado (REDMAR) y refiere los datos al NMMA1995 mientras que BCN3, propiedad de la Autoridad Portuaria de Barcelona, los refiere a la Red Topogr谩fica del Puerto de Barcelona observada mediante t茅cnicas GNSS. Ambos mare贸grafos est谩n separados unos 3Km. en l铆nea recta y unos 8Km. por tierra. El objetivo ha sido determinar la diferencia existente entre los ceros de referencia de los dos mare贸grafos. El nivel de mar observado por los mare贸grafos, sin tener en cuenta la acci贸n del oleaje, est谩 afectado por la marea astron贸mica y la marea meteorol贸gica. La marea meteorol贸gica es de tipo aleatorio, por el contrario la marea astron贸mica es de car谩cter determinista y se puede resolver realizando el an谩lisis de arm贸nicos. Para ello, una vez realizado el control de calidad de los datos brutos, se utiliz贸 la aplicaci贸n T_TIDE en MATLAB obteniendo como resultado para cada mare贸grafo tres gr谩ficas y dos ficheros. Las gr谩ficas representan respectivamente el nivel del mar observado, la marea astron贸mica y la meteorol贸gica o residuo y de los dos ficheros, uno corresponde al c谩lculo de los componentes arm贸nicos, del que nos interesa la componente Z0 (nivel medio del mar) y el segundo contiene la componente meteorol贸gica. Se puede concluir en que el cero de referencia de BCN3 est谩 situado 0,096 metros por encima del NMMA 1995.Peer ReviewedPostprint (published version

    Breakwater settlement monitoring with InSAR data

    No full text
    This paper presents a use case of the Persistent Scatterer Interferometry (PSI) technique apply to Civil Engineering to monitor the dikes settlement on the Port of Barcelona. A geostatistical analysis of the two available datasets of PSI data have been made on a Geographic Information System to obtain a continuous deformation surface. This approach allows us to study the different subsidence velocities that occur within the sections of the breakwater which are in a different consolidation phase. The two datasets of InSAR data were obtained from different satellites and different time periods so a new methodology was developed for concatenating the two measurements a posteriori. Finally, InSAR and GPS measurement are compared to validate the obtained results.Peer ReviewedPostprint (published version

    Geodetic infraestructure in the Ibiza and Barcelona harbours for sea level monitoring

    No full text
    The presentation is directed to the description of the actual situation and relevant information of the geodetic infrastructure of Ibiza and Barcelona sites for sea level determination and contribution to regional sea level rise. Time series are being analysed for mean sea level variations www.puertos.es. .In the framework of a Spanish Space Project, the instrumentation of sea level measurements has been improved by providing the Barcelona site with a radar tide gauge Datamar 2000C from Geonica s.l. near an acoustic tide gauge. Puertos del Estado installed in 2007 a MIROS radar tide gauge and the Barcelona Harbour Authority a GPS referente station in the roof of the new Control Tower situated in the Energy Pier. The radar sensor is over the water surface, on a L-shaped structure which elevates it a few meters above the quay shelf. 1-min data are transmitted to the ENAGAS Control Center by cable and then sent each 1 min to Puertos del Estado by e-mail. There is a GPS station Leica Geosystems GRX1200 GG Pro and antenna 1202. Precision levelling has been made several times in the last two years because the tower is founded in reclaimed land. The measured settlement rate is about 1cm/year that may be could mask the values registered by the tide gauge. A description of the actual infrastructure at Ibiza harbour at Marina de Botafoch, is presented and its applications to sea level monitoring and altimeter calibration in support of the main CGPS at Ibiza harbour. It is described the geometrical precision levelling made in June 2013 between the radar tide gauge and the GPS station. In particular, the CGPS located at Ibiza harbour is essential for its application to the marine campaign Baleares 2013, near Ibiza island. The main objective is to determine the altimeter bias for Jason-2, about 9:09 UTC September 15, 2013, and Saral/AltiKa, about 05:30 UTC September 16, UTC. These activities has been received funding of the Ministerio de Ciencia e Innovacion under Spanish National Project CGL2009-13435/CLI.Peer ReviewedPostprint (published version
