High Resolution Marine Seismic Surveying in the Sudbury Basin, Ontario, Canada
Bibliographic record
Abstract
Summary The Sudbury basin in Ontario, Canada has been historically studied due to its economic mineral deposits and unique geology. High resolution marine seismic surveying was conducted in two lakes to explore sediments for imbedded neo-tectonic indicators providing evidence of neo-tectonic activity prior to anthropogenic influence. Seismic profiles revealed four distinct acoustic facies correlating to sediment facies described and cored in the encompassing Huron basin. Utilizing these interpretations a rudimentary chronology was established for the sediment stratigraphy based on the timing of significant regional events such as deglaciation and the warm/arid Hypsithermal climatic event. Faulting was confined to older (> 8000 ybp) sediments while sediment slumping was recorded throughout the succession, revealing persistent neo-tectonic activity since deglaciation. This study demonstrates the use of shallow marine seismic surveying for reconstructing late and post glacial environments, and how this information can be applied for investigating on-going natural hazards such as neo-tectonic activity.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
