Mid-latitude complex trough-mouth fans, Laurentian and Northeast fans, eastern Canada
Bibliographic record
Abstract
Submarine fans seaward of mid-latitude glacial ice streams in cross-shelf troughs show a complex evolution. Unlike high-latitude fans where glacigenic debris-flows predominate, meltwater discharge appears to play a larger role in fan evolution, reflected in the growth of high channel-levees and the development of broad, flat-floored submarine valleys. Where canyons are deeply incised, large mass-transport events may be triggered leading to much of the mid-fan area being constructed of mass-transport deposits (MTDs). The Laurentian and Northeast fans are two large submarine fans that lie seawards of major glacial cross-shelf troughs on the continental margin south of Nova Scotia, Canada (Fig. 1a). Both fans span more than 300 km from the shelf break to the Sohm Abyssal Plain. The fans have well-developed channel-levee systems with the western levee of the Laurentian Fan forming a major constructional feature on the margin (Fig. 1c, e). Multibeam and side-scan data coverage of the fans is more complete for the lower fan of Northeast Fan and for the middle and upper fan of Laurentian Fan. Fig. 1. Multibeam bathymetry, backscatter, side-scan and seismic-reflection data over large mid-latitude trough-mouth fans south of …

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.
