Pleistocene ice outlets on the central Scotian Slope, offshore Nova Scotia
Bibliographic record
Abstract
The style of Quaternary sedimentation on the central Scotian Slope near the Shelburne G-29 well is interpreted from seismic reflection profiles. Three types of shelf-edge ice margin produced different styles of sediment accumulation in the later Quaternary on the slope. 1) Ice margins of ice streams persisted for many thousands of years at the shelf edge and resulted in active sedimentation of coarse, channelled deposits, and debris flows. 2) Seaward of outer shelf banks, ice advance onto the upper slope was short lived and sedimentation was dominated by fallout from ice-margin plumes. 3) Under intermediate conditions, ice advance deposited upper slope till and subglacial meltwater cut gullies, but active sedimentation seaward of a broad ice front was lacking. These ice-margin facies overlie an early Quaternary prodeltaic margin and a major debris-flow deposit. The Quaternary sediments are offset by slope-parallel faults that have provided pathways for mud diapirs.

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.
