- Аннотация: During testing of the new native program of tidal prediction ATLANTIDA3.1_2014 the data of gravimetric observations on the Japanese Antarctic station Syowa (Kim et al., 2011) were subjected to substantial additional processing. First of all, these data are interesting due to the rather high latitude of the site location (69º.007 S). This allowed, in particular, to compare with greater reliability two latitudinal distribution of gravimetric amplitude delta-factors: resulting in the construction of a well-known model DDW/NH (Dehant V. et. al., 1999) and calculated in the work (Spiridonov E.A., 2014). At the same time, the stable and accurate superconducting gravimeter located at the station is set just 250 meters from the shoreline, i.e. largely influenced by ocean. In this regard, the interest is also represented in the performance testing in Antarctic of modern oceanic tidal models (in particular, FES2012).As a result of the analysis it was found that the best oceanic tidal model in the Antarctic zone is TPXO7.2. This coincides with the results of work (Kim et al., 2011). However, in general, the range of results obtained by different ocean models proved to be quite large. Nevertheless, it was shown that at high latitudes, regardless of the choice of oceanic tidal model, application of the theoretical amplitude delta- factors for the Earth without the ocean from DDW /NH model in more than 70 % leads to a more distant from the observation results than the use of amplitude factors of our model.
