Abstract

fetched live from OpenAlex

Summary The General Dynamics Marine Vibrator System completed the industry’s first pilot marine seismic survey in October of 2023. Source signatures for both the marine vibrator and airguns are processed and compared for a single line. Comparisons between peak over pressure, peak and average radiated power, total radiated energy, in-band radiated energy, power and energy spectral densities, bandwidth, and repeatability are made. Particular attention is paid to the difference in out-out-band radiated sound between the air guns and APS marine vibrators (which are specifically designed to have low harmonic distortion, high fidelity waveform control, and low out-of-band radiation). The microsecond-level GPS-based timing synchronization of the marine vibrators is discussed and characterized. In addition, the continuous, sweep-by-sweep quality assurance system that monitors timing synchronization and source signature fidelity, available in near-real-time both locally to the operators and remotely to the shore-based personnel, is shown. Special thanks is given to TotalEnergies, Shell, and ExxonMobil for sponsoring the pilot via the Texas Engineering Experiment Station, and to Kappa Offshore Solutions for efficiently conducting the pilot with zero HSE incidents.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
