Results of tidal gravity observations in Tenerife , Canary Islands

c Tidal gravity observations have been carried out in Tenerife (Canary Islands) at the. base of the Teide volcano, more than two thousand meters above the sea level. The measurements have been done using a Lacoste&Romberg-G gravimeter (number 665), with electronic feedback during a period of six months. The results show, after a suitable correction of the ocean loading and attraction' effects, a good adjustment with the body tide response. The environment conditions of the station produced also instrumental effects during the obs'ervation period leading to disturbances in the long term signal.
