Sv-Wave And P-Wave High Resolution Seismic Reflection Using Vertical Impacting And Vibrating Sources
Bibliographic record
Abstract
Shear wave seismic reflection profiles are generally acquired using sources and receivers horizontally oriented to avoid interferences of the signal with unwanted energies like converted- or P-waves. With various tests using a sledge hammer impulsive source, we have defined a window of acquisition for SV-wave recording. The SV reflected signal can be differentiated from the surface waves in the frequency domain. Our tests have been conducted on the Champlain Sea sediments in the vicinity of Ottawa, Ontario, Canada. These Sediments have already proven to be ideal for P-wave and SH-wave high-resolution seismic imaging. SV sections using a vibrating source otbained over such environment display the highest resolution we have yet observed in any land-based seismic reflection survey. Tests over more compacted sediments have been less conclusive but it is hypothesized that this new SV high resolution seismic reflection method may be used in sedimentary environments that are already kwown to give good results with the SH-wave reflection method. The greatest benefit of the method is that with the same raw shot records it is possible to process a P and an SV high resolution seismic section.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
