TY - JOUR T1 - Theoretical Solution and Applications of Ocean Bottom Pressure Induced by Seismic Waves at High Frequencies JF - Geophysical Research Letters Y1 - 2022 A1 - Deng, Han A1 - An, Chao A1 - Cai, Chen A1 - Ren, Hengxin AB - Previous studies have demonstrated that the ocean-bottom pressure associated with seismic seafloor motion is linearly proportional to the vertical seafloor acceleration, for frequencies much lower than the resonance frequency of water layer (c0/4h, c0 water sound speed, h water depth). In this article, we use realistic observations to verify a theoretical relation between the ocean-bottom pressure and vertical acceleration up to the water resonance frequency. We then show two applications of the theoretical relation. First, the pressure amplitude recorded by differential pressure gauges is calibrated, and the calibration coefficient is found to vary by frequency. Second, Rayleigh wave phase velocity near the water resonance frequency can be calculated from recordings of pressure and vertical seafloor acceleration at a single station, which is useful to constrain the shallow Earth structure.
