A numerical model of postglacial relative sea level change near Baffin Island
Bibliographic record
Abstract
It is intuitive that some form of causal relationship must exist between the ablation of late Pleistocene ice sheets and the variations in RSL (relative sea level) seen preserved in the geologic record of coastal areas. The form of this relationship has been quantified in numerical models which successfully explain the major features of the global postglacial RSL record ( Farrell and Clark, 1976 ; Peltier and Andrews, 1976 ). By increasing the spatial resolution of these models, Quinlan and Beaumont (1981 , 1982 ) examined details of the RSL record within Atlantic Canada and proposed a compatible late Wisconsin ice reconstruction for that area. The current paper uses the Quinlan and Beaumont (1982) approach to analyse the RSL record of the region around Baffin Island. There are two principal objectives: first, to derive an ice reconstruction consistent with the known RSL record; and second, to use this reconstruction to estimate the form of the RSL record for sites where direct RSL Indicators are either absent or anbiguous in their implications.

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.
