Preliminary results of a study on active layer hydrology in the discontinuous zone at Schefferville, Nouveau-Québec
Bibliographic record
Abstract
A detailed study of the water balance of a lichen tundra underlain by permafrost was started in September 1976. Data collection at the 9 000 m2 site near Schefferville, Québec includes air and ground temperatures, precipitation, évapotranspiration, and changes in soil moisture storage as well as incoming short-wave and net all-wave radiation. It is shown that the development of the active layer is strongly influenced by the amount and distribution of moisture in the soil at freeze-up. Moisture transfer within the unsaturated zone is shown to be strongly influenced by the temperature field within the active layer during freeze-up. During the thaw season the confinement of infiltrated water by permafrost is not only a major soil moisture reservoir and medium for suprapermafrost ground water flow, but it is also shown to maintain évapotranspiration at or near the equilibrium rate for the tundra as well as causing a significant increase in evaporation from permafrost induced wetlands.

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.
