Abstract: Since 1995 two short base-length horizontal pendulums are continuously recording at the station Cueva de los Verdes (Geodynamics laboratory of Lanzarote). Both tilt-meters are modified from the classical Ostrovsky pendulums and are adapted to the local features of the station. The tilt-meters have a working range of measurements of +-20seconds of arc and can resolve up to one second of arc. Such technical properties allow determining the precise tilt response to Earth tides. The tidal tilt models obtained show an important influence from ocean tides. Thus, the estimated amplitude for the main harmonic constituents is of some 4-5 times larger than values measured at continental stations. In this work, the ocean loading and attraction effect, which are computed from global ocean tidal models supplemented with precise regional and local ones will be evaluated. Hence, tidal tilt observations can be corrected from this effect.
