| 英文摘要 | By using tidal gravity observations obtained by lcr-et21 gravimeter at zhongshan station and gwr058 instrument at syowa station in antarctic, we have studied the ocean tide loading (otl) effects with the 3 latest global ocean models (dtu10, eot11a, ham11a) and ambient noise. the results show that the amplitude residuals of o-1 and m-2 decrease from 13.83% and 20.55% to 5.32% and 5.95% at zhongshan station and decrease from 10.84% and 21.52% to 1.91% and 3.40% at syowa station after the otl correction on gravity with the average of 3 ocean tide models. this indicates the effectiveness of the otl correction. using fft transformation with hanning window, we obtain the seismic noise magnitude (snm) in seismic band, which values are 1.574 (zhongshan) and 1.289 (syowa), respectively. however, in tidal band, the ambient noises at zhongshan station are one order higher than syowa station, mainly caused by the different instruments and the local environment of the station. our results can provide effective reference for further use of gravity data of the antarctic to study the local environment and the global dynamics. |
