Abstract

fetched live from OpenAlex

Beaufort Mackenzie (BMB) permafrost and methane gas hydrate (GH) occurrences appear paradoxical. Relict terrestrial permafrost and GH from the Pleistocene sea level lowstand are degrading slowly in response to marine transgression below the Beaufort Sea. In many onshore Mackenzie Delta (MD) locations, such as at the Mallik site, thick permafrost and GHs are also degrading slowly in response to Holocene ground surface temperature warming. In contrast, taliks commonly lacking GH indications are inferred below shallow lakes.Why should taliks form below shallow lakes while submarine permafrost and GHs persist? We compare models of talik, permafrost and GH behavior below such lakes and compare them to models of BMB GH occurrence to describe lacustrine inundation effects and the factors controlling the contrasting MD permafrost/GH and talik environments.

Full frame distilled prediction

Teacher imitation

Not 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.
