We investigate a nearly 8-year record (2010–2018) of the superconducting gravimeter OSG-
060 located at Djougou (Benin, West Africa). We first perform a tidal analysis with ET34-ANA
v7. 1 software that leads to the gravimetric amplitude and phase factors for all separable
waves according to the available time duration. We test nine different ocean tide models for
the main eleven tidal constituents (Ssa, Mm, Mf, Q1, O1, P1, K1, N2, M2, S2, K2). After
correction for ocean tidal loading we obtain the real and imaginary parts of the residual …
