Carbon isotope stratigraphy for the late Maastrichtian based on Site U1403
Bibliographic record
Abstract
Review of "Maastrichtian carbon isotope stratigraphy and cyclostratigraphy of the Newfoundland margin (Site U1403, IODP Leg 342)" by Friedrich et al. for Climates of the Past.The ms describes the bulk carbonate carbon isotope stratigraphy of IODP Site U1403 for the late Maastrichtian using cyclostratigraphy based on Fe/Ca and magnetic susceptibility to establish an astronomically calibrated age model.The record is subsequently compared with that of the Zumaia section in northern Spain and claim is made that the new record reflects global climate change more reliably.In that case this would be an important contribution as the latest Cretaceous is a fascinating interval with both short warming and cooling periods, and potentially leading to a delicate state C1 CPD Interactive comment Printer-friendly version Discussion paper

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.
