• Resumen

  • L'Estartif tide gaude is a classical floating tide gauge set up in l'Estartit harbour (NE Spain) in 1990. Data are taken in graphic registers from which each two hours the mean value is recorded in an electronic support. In the framework of a Spanish Space Project, the instrumentation of sea level measurements has been improved by providing this site with a radar tide gauge and with a continuous GPS station nearby. This will have a significant incidence in the satellite altimeter calibration activities. Both the classic gaugeand the radar sensor are working in parallel way and have been controlled each week. Also a qualitity control has been clone to ensure the self-consistency of the records collected from both methodologies. The tide gauge heights are geo-referenced to a bechmark in the adjacent jetty identified as number 314094002 in the Cartographic Institute of Catalonia.
