A Dynamic Process Model of Palsa Genesis and Development based on Geomorphologic Investigations at the Boundary Ridge Palsa Bog
Bibliographic record
Abstract
This original research of seasonal thermodynamic and dynamic geomorphologic processes at the Boundary Ridge palsa bog near Schefferville, Quebec reports characteristic differences in heat flow (Q,), and resulting permafrost mass aggradation/degradation behavior, between a mature-phase palsa (Palsa A) and young-phase palsa (Palsa B). Quantitative analysis of September 1976-August 1977 thermal data indicates how changing palsa material characteristics and bog thermodynamics affect palsa geomorphology. Q, patterns for Palsa A show greater amplitude, and shorter active-layer heat loss duration, at its center than along its periphery. Basal active-layer ice aggradation was more evident in Palsa A than Palsa B. Although Palsa A experienced lesser Q, amplitudes than Palsa B, increased Q,, phase lag resulted in more heat loss and productive ice growth at depth. Palsas A and B experienced permafrost-zone isothermal conditions just below 0°C for seven to eight months of the year, interrupted only by the winter

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.
