The marine cable includes a plurality of active modules. Extend the bandwidth of your data for any marine acquisition type or technique. seismic data and their acquisition, processing, and interpretation processes. Because nearly all modern seismic data are in digital form in order to be stored and analyzed in computers, we need to learn several important concepts about sampled time series such as sampling rate and aliasing; the latter is an artifact due to under-sampling. During the seismic data acquisition process, marine positioning equipment provides acoustic, compass, and depth measurements so seismic data processors can tie navigation and location data to geophysical data to determine the location of potential reserves for precise drilling operations. Seismic Data Acquisition: Modern Land and Marine Technologies and Methods by R. Malcolm Lansley. Marine. The appropriate energy source and receiver depend on the location and the application.
