This report discusses recent progress on the programme of high precision tidal gravity. The programme is now primarily concerned with the field measurement of tidal gravity and a description of present experiments and preliminary results is given. The preliminary results show that a measurement accuracy in amplitude for the principal tidal harmonics O sub 1 and M2 of or - 0.2 is achievable and that phases may be determined to or - 0.1 deg. This is approaching an order of magnitude improvement over existing measurements. Keywords Earth Tides Tidal Gravimeters Ocean Tide Loading Great Britain.
