Description
Summary:—Tidal ocean corrections for gravity observation play an important part in monitoring studies. Tidal ocean models were tested by Transcontinental Tidal Gravity Profile (TTGP) results. This part of the global tidal network was used for study the influence of the Atlantic and Pacific oceans up to coastline. Our tidal result agrees with static theory and had a weak ocean dynamic influence (Schiwiderski and other models) into the center of the Eurasian continent. Near the coast, where ocean effects were strong, the influence increases. In the East part of TTGP, we obtained observation results for Khabarovsk region, for Sakhalin Island and for Primorye region (Sea of Okhotsk and Sea of Japan). In the South part of the Primorye observation (Russian Far East) long-term measurement was completed at the Posyet Bay level station and Cape Shultz gravity station. Based on the results, a selection of ocean tidal models was made and a number of unresolved issues were determined.
