Geophysical and Geotechnical Characteristics of Champlain Sea Sediments in the Ottawa Valley, Canada
Bibliographic record
Abstract
Summary The soft Champlain Sea sediments of the Ottawa Valley, Canada are susceptible to earthquake-triggered ground failure and contribute to significant amplification of earthquake shaking. We investigate the geophysical and geotechnical properties of Champlain Sea sediments and the underlying shape of the bedrock basin. The objective of the multidisciplinary approach is to characterize the geophysical and geotechnical signatures of high sensitivity clay and silt, and to improve understanding of how these sediments respond to earthquake shaking. Geophysical techniques employed in this study include microtremor recordings, high-resolution seismic profiling, electrical resistivity imaging, and downhole geophysical logging. Geophysical and geotechnical data suggest a bedrock basin up to 98 m deep with a soft sediment fill that exhibits localized evidence of leaching and high sensitivity. Results are consistent with the presence of retrogressive landslide scars in the Breckenridge study area.

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.
