WebABSTRACT Near-field hydrophone (NFH) data from hydrophones attached to a marine source array are commonly recorded for every shot in a seismic survey and are typically used for source signature estimation. There is recent interest in using NFH data to acquire near zero-offset reflection data in the sub-surface that are used in seismic ... WebJun 25, 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.
