The Influence of Sediments, Lithosphere and Upper Mantle (Anelastic) With Lateral Heterogeneity on Ocean Tide Loading and Ocean Tide Dynamics

Ocean tide loading (OTL) and ocean dynamics (OTD) are known to be affected by Earth's internal structures, with the latter being self-attraction (SAL) potential. Combining 3D earth models Lyon LITHO1.0, we construct a hybrid model quantify coupled effect of sediments, oceanic continental lithosphere, anelastic upper mantle on OTL OTD. Compared PREM, this more realistic produces significantly larger vertical displacement up 3.9, 2.6, 0.1 mm for M2, K1, Mf OTL, respectively. Moreover, it shows smaller vector difference amplitude 0.2 than PREM observations at 663 Global Navigation Satellite System stations, confirmation cumulative due these features. On other hand, find resonant impact wider extent magnitude OTD, especially M2 K1 tides. Specifically, is concentrated in ranges 0–6 0–1.5 respectively, which considerably SAL (mostly 0–2 0–1.0 mm, respectively). Since similar level compared accuracy modern data-constrained that require correction geocentric induced displacements, regard its consideration potentially beneficial OTD modeling.
