Late Quaternary geological history of the SW Grand Banks Slope and Rise off Green Bank and Whale Bank: implications for geohazard assessment
Bibliographic record
Abstract
A reconnaissance survey of late Quaternary stratigraphy and geohazards has been carried out on the deep continental margin seaward of Green Bank, Haddock Channel and Whale Bank, based on sparse Huntec sparker lines and seven new piston cores. The area is crossed by the large Haddock valley seaward of Haddock Channel. To the southeast, Whale Slope is relatively undissected, but the slope seaward of Green Bank is dissected by tributaries of Haddock and Halibut valleys. Five regional reflections were correlated throughout much of the study area in Huntec sparker profiles. The distribution of major mass-transport deposits, evacuation surfaces and headscarps was mapped. Most piston cores penetrated to between Heinrich layer 1 and the last glacial maximum and recovered principally mud. Cores adjacent to Haddock Valley contained abundant thin sand beds of late Pleistocene age. Cores were correlated with adjacent long core records on St Pierre Slope and at the Narwhal well site. Extrapolation of ages from cores suggests that the recurrence interval of regional failures is several tens of thousands of years. More frequent local failures are found at the foot of active fault scarps.

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.
