Ocean effects on gravity tides in the Iberian Peninsula

Abstract

As a continuation of our research presented at the 8th International Symposium on Earth Tides in Bonn, we have completed a total of 14 stations of the vertical component in Spain. The strong ocean influence in these data makes them good test for the different maps of oceanic tides. Starting from the maps of Schwiderski, Hendershott, Parke and Zahel, the effects of the ocean tides have been computed for our gravimetric stations. We have prepared maps for the neighborhood of the iberian peninsula, including the Alboran and Balearic seas, using results from hydrography and pelagic observations. The new maps, digitized with a grid of 0º .5 x 0º .5, have been computed for the Spanish stations, and they have been completed simultaneously for the mentioned maps.
