<p>The structure of Antarctic ice sheet may provide important clues about potential ice-bedrock interaction. In this study, we present a high-resolution shear wave velocity image of the Larsemann Hills region in Prydz Bay, East Antarctica, based on multimodal surface wave tomography using ambient seismic noise data collected from a linear array of 100 seismic stations spanning ~21 km near Zhongshan Station. To improve the process of dispersion curves extracted from linear subarrays, we employed a random subarray strategy preventing the loss of resolution with smaller subarrays and preserving horizontal detail when larger subarrays are used. Our suface wave imaging result reveals a low-velocity ice layer in parts of the surveyed area, displaying horizontal variations in shear wave velocity structure. These features are consistent with results from ice-penetrating radar (IPR) profile and horizontal-to-vertical spectral ratio (HVSR) analysis, indicating laterally heterogeneous ice-sheet structures associated with a low-velocity layer near the icebed interface. The observed low-velocity layer may reflect the combined influence of fault-related processes, geothermal effects, and ice-flow dynamics acting after the formation of the ice sheet. Overall, this study demonstrates that high-resolution passive seismic method can provide valuable insights into the coupled evolution of subglacial structure and the overlying ice sheet.</p>
