STRATIGRAPHY, DISTRIBUTION OF ACTIVE LAYER AND DISCONTINUOUS PERMAFROST IN KANGIQSUALU J JUAQ BASIN, NORTHERN QUEBEC
Bibliographic record
Abstract
The hydrological basin is located to the southeast of Ungava Bay. This study is carried out to investigate the stratigraphy which is necessary for the understanding of the hydrological and thermal regimes of this basin. To establish the stratigraphic framework. surface geophysical surveys have been conducted. In addition, thermistor cables and piemmeters are installed at three sites in order to obtain the parameters required for the hydrological and thermal investigations. The geophysical results are calibrated with drill hole information. The results of a ground probing radar profile are correlated with those of electrical soundings. This integrated approach facilitates the interpretation of geophysical soundings on uncalibrated sites and allows a better understanding of the stratigraphic sequences in marine sediments. Detailed transect surveys are conducted across the basin. These surveys indicate that permafrost covers 40 % of the basin area Its thickness, determined from geophysical surveys, varies from 2 to 20 m (average 11 m). The average permafrost thickness is similar in sand and gravel, till. and clayey silt deposits. On the test sites, the thickness of permafrost obtained from geophysical interpretation is compared with the extrapolated temperature profiles measured along drill holes. In addition, the depth extent of permafrost is correlated with snow cover thickness. Isotemperature sections and geoelectrical pseudo-sections indicate that permafrost is colder in

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.
