    • In order to understand better the stress field and dynamics characteristic of the lithosphere at Prydz bay in the Antarctica, rotation-correlation shear wave splitting method is used to study 5 earthquakes recorded by three ocean bottom seismometers recovered at Prydz bay during the 31th Chinese Antarctic Research Expedition to obtain the anisotropy characteristics of the continent and ocean transition of Prydz bay in this paper. Our inversion results show strong anisotropy in the lithosphere of Prydz bay with spatial differences in small scale. The fast shear wave polarization directions are from N40°E to N60°E, fast and slow shear wave times delay are from 0.2 s to 1.3 s. We think that the anisotropy at the oceanic part is dominated by the mantle flow of mid-ocean ridge spreading, while the continental part is dominated by the relic structural fabric of the ancient lithosphere at the top of the upper mantle, and the middle zone with shallower and thinner anisotropy layer may be influenced by the both reasons above.
