Historical relative gravity observations and the time rate of change of gravity due to postglacial rebound and other tectonic movements in Canada
Bibliographic record
Abstract
A major re‐adjustment of the primary Canadian Gravity Standardization Network (CGSN) is carried out based on relative gravity measurements spanning over 40 years. Anticipating that secular variations of gravity, dominated primarily by the continuing process of glacial isostatic adjustment could be detected, we parameterize the time rate of change of gravity ( ) into the observation equation and estimate it directly from a generalised least squares solution. Time rates of change of gravity ( ) from repeated absolute gravity observations, as well as absolute gravity values at selected sites are used as weighted constraints. The results are presented in form of a map and demonstrate that the primary CGSN, with its over 40‐year‐long history, can provide us with useful constraints for the evaluation/verification and refinement of post‐glacial rebound models.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
