Abstract

fetched live from OpenAlex

The dating of cryoturbated palaeosols associated with past ice-wedge activity on late-Holocene sandy fluvial terraces in a region of continuous permafrost leads to an interpretation of periods of ice-wedge growth and active cracking that alternated with periods of decay, dormancy and active layer deepening. The reconstruc tion corresponds with palaeoclimatic information obtained from existing Arctic-wide and regional proxy rec ords. The ‘Little Ice Age’ stands out as a period of intense ice-wedge activity in the study area. It was followed by a warm thawing interval during the first half of the twentieth century. From ad 1946 to 1991, a well-documented cooling of the climate took place, which reactivated 94% of the studied ice wedges. The pyramidal shape of ice-wedge tops and the depths of the upgrowth features could be correlated between sites several kilometres apart, clearly indicating a regional climatic response. The mean annual air temperature dropped from about–7.8°C in 1946 to–8.9°C in 1991. The threshold temperature for active ice wedges probably lies within this range.

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.
