Data obtained from a transcontinental tidal gravity profile across the United States were analyzed. Results for the principal tidal constituents M(2) and O(1) have shed light on the long-standing problem of the indirect influence of ocean tides on the solid-earth tide. The profile consists of nine observational stations distributed almost evenly around latitudes 39 to 41 degrees north across the United States. The observed values of the gravimetric factor and the phase were found to depend on the tidal characteristics of the Atlantic and Pacific oceans. There is no observable correlation between tidal gravity parameters and the regional geology. When the influence of ocean tides is taken into account, it is possible for the first time to bring the gravimetric factors and phases for all the stations of a transcontinental network into a consistent system within the framework of the earth tidal theory.
对一条跨越大西洋的潮汐重力剖面所获得的数据进行了分析。主要潮汐成分 M(2) 和 O(1) 的结果揭示了长期存在的海洋潮汐对固体潮汐的间接影响问题。该剖面由分布在美国北纬 39 度至 41 度之间的九个观测站组成，几乎均匀分布。发现重力因子和相位的观测值取决于大西洋和太平洋的潮汐特征。潮汐重力参数与区域地质之间没有可观测到的相关性。当考虑到海洋潮汐的影响时，就有可能首次在地球潮汐理论框架内将跨大陆网络的所有站点的重力因子和相位纳入一个一致的系统中。
