WebIn this study, measurements by a horizontal hydrophone array towed by the R/V Marcus G. Langseth behind a seismic source array have been used to characterize short-range propagation of airgun pulses and predict the acoustic energy radiated from a … Web9 aug. 2024 · The pre-conditioning of the two component OBN seismic data before summation is a necessary step for both hydrophone and vertical geophone components. To remove the shear wave leakage from the vertical geophone components, a denoise methodology developed by Jeong and Tsingas ( 2024) using all four components was used.

The … Web25 jun. 2024 · For his part, Guimarães is working with Bluware, a Houston-based seismic data company, to sharpen information-processing times. Because ocean bottom nodes are already on the seafloor, the echoes their hydrophones capture do not need to be bounced back up to a waiting ship. But it can still take time to recover the devices and study the data. Web5 dec. 2024 · Vector hydrophone arrays also face the problem of grid mismatch when using the compressed sensing method for array design. To the best of our knowledge, there are few articles on the vector hydrophone array design under the o -grid model. For this reason, the vector hydrophone array design under the o -gird model is studied in this … cables type
