Tidal gravity observations were made at Asuka Station (71.5¿S, 24.1¿E), Antarctica. The LaCoste-Romberg model G--05 gravity meter was altered to integrate an electrostatic feedback amplifier and was installed in a snow pit. Records for tidal analysis were obtained from June 26 to November 13, 1987, at a sampling interval of 30 min. From the estimated tidal amplitudes, corrections for the oceanic effects were made using Schwiderski's cotidal maps. The ocean tide corrected Δ factors, which define the response of the deformable Earth to lunar-solar tidal forces, were found to be 1.169¿0.008 (O1), 1.127¿0.017 (P1), 1.135¿0.006 (K1), 1.261¿0.003 (M2), and 1.302¿0.039 (S2). The diurnal Δ factors agree with those obtained from statistically derived formulas by Melchior and De Becker. However, the semidiurnal Δ factors (M2 and S2) are 10% larger than the theoretical values predicted by Wahr. This is much larger than the typical 1--2% discrepancy between the statistical model and theory. Similar tidal gravity observations made at Syowa Station (69.0¿S, 39.6¿E) yielded consistent results with those monitored at Asuka Station. The observed M2 Δ factors have a tendency to increase from the equator toward the southern high latitudes. The increasing effect of inaccurate ocean load tidal corrections may be due to Schwiderski's cotidal chart. Tidal analysis resulted in a gravity admittance of -0.24¿0.04 μGal/mbar for the air presure change at Asuka Station. The smaller magnitude compared with the typical value of -0.35 μGal/mbar for a normal crust may be explained by the loading deformation of the ice sheet under the air mass covering an extent of 30 km over the site. ¿American Geophysical Union 1993
