Geoacoustic Model of Coastal Bottom Strata off the Northwestern Taean Peninsula in the Yellow Sea

摘要: In the shallow coastal area, located off northwestern Taean Peninsula of eastern Yellow Sea, geoacoustic models with two layers were reconstructed for underwater acoustic experimentation and modeling. The Sea experienced glacio-eustasy sea-level fluctuations during Quaternary period. Coastal sedimentation in was characterized by alternating terrestrial marine deposits that reflected fluctuating sea levels. based on data from piston, grab cores high-resolution 3.5 kHz, chirp seismic profiles (about 70 line-kilometers, respectively). Geoacoustic extrapolated down to 3 m depth models. property seafloor sediments is considered a key parameter modeling environments. For simulating actual environments, P-wave speed adjusted in-situ below floor using Hamilton method. proposed could be used submarine inversion shallow-water environments study area.
