A <sup>10</sup>Be chronology of early Holocene local glacier moraines in central West Greenland
Bibliographic record
Abstract
New cosmogenic 10Be exposure ages constrain Greenland Ice Sheet (GrIS) deglaciation and the culmination of a local glacier advance on the southern shore of Nuussuaq (peninsula) in central West Greenland. Mean ages of GrIS deglaciation and local glacier moraine deposition are 10.5±0.1 ka (n = 2) and 10.4±0.2 ka (n = 5), respectively. The similar ages suggest an advance/stillstand of local glaciers soon after the local retreat of the GrIS. The moraines dated in this study may be correlative to the nearby Disko Stade moraines. Moraine chronologies for both GrIS moraines and our local glacier moraines in central West Greenland correspond to detrital carbonate peaks in a Labrador shelf marine sediment core that records Laurentide Ice Sheet (LIS) discharge from Hudson Strait. Large freshwater discharge events into the North Atlantic sub‐polar gyre have been linked to abrupt cooling events in the Northern Hemisphere during the early Holocene. We propose LIS freshwater input to the sub‐polar gyre and associated regional cooling as the main driver for advance/stillstand of both local glaciers and the GrIS in central West Greenland during the early Holocene.

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.
