Method and apparatus for marine source diagnostics

A graphical user interface (GUI) and control system for controlling and testing an acoustic source. The control system includes real-time data processing of individual source near-field measured signatures and synthesis of array far-field signatures. The control system determines individual source out-of-specification conditions and computes far-field signatures based on an array configuration and, when applicable, excluding failed sources. Source, array, and troubleshooting information are presented to a user in real-time over a GUI monitor to allow informed decision-making regarding continued and/or modified survey operations and operational parameters.
