Slope-fan and glacial sedimentation on the central Beaufort continental slope, Arctic Canada
Bibliographic record
Abstract
Quaternary sedimentary environments in the central Beaufort Sea continental slope are evaluated using interpretations of three-dimensional (3-D) seismic data. Previous knowledge of slope sedimentation has been limited to sparsely located, low-resolution vintage seismic-reflection profiles. The 3-D data image a number of channel-levee complexes that comprise a previously unknown slope fan we call the Kugmallit fan. The Kugmallit fan includes angular unconformities, and a broad spectrum of sediment deformation from coherent slide blocks and slumps to debris-flow deposits. The fan has been regionally truncated by a planar erosional unconformity overlain by laminar glaciomarine to hemipelagic sediments. This unconformity represents a significant change in depositional style, likely the result of reorganization of Plio-Pleistocene fluvial systems during the Last Glacial Maxima into the present day Mackenzie River drainage system. We infer that overpressure and fluid flow within the sediments in this slope fan are potential geohazards for exploration drilling.

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.
