GULLY FORMATION AND CLIMATE CHANGE IN THE CANADIAN ARCTIC: A POSSIBLE ANALOGUE OF NEAR-RIM, IMPACT-CRATER GULLIES IN UTOPIA AND WESTERN ELYSIUM PLANITIA, MARS. R.J. Soare
Bibliographic record
Abstract
Introduction: The origin and development of Martian gullies remains a controversial topic within the planetary science community. Formation hypotheses are diverse. In earlier work [1], we hypothesised that the recent formation of some near-rim impactcrater gullies (Fig. 1) in Utopia and western Elysium Planitia was related to obliquity-driven rises in lateAmazonian mean temperatures and to the localised thawing of near-surface ice-rich regolith or permafrost (permafrost whose pore space is taken up if not exceeded by the presence of frozen water), perhaps even massive ice beds, that were emplaced during earlier obliquity cycles [2]. Possible geological markers of this ice-rich permafrost are lobate (alas-like) depressions [3-5], pingo-like mounds [6-8] and small-sized polygonal patterned-ground [3,9], all of which are ubiquitous in the region.

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.
