Permafrost and environmental conditions at stream crossing sites in the northern Mackenzie Corridor, Northwest Territories
Bibliographic record
Abstract
Aboriginal Affairs and Northern Development Canada (AANDC) and the Geological Survey of Canada established ground temperature monitoring sites at three stream crossings along the northern Mackenzie Corridor in order to examine the impact of local environmental conditions on permafrost. Ground temperatures were measured between August of 2009 and August of 2010 at hilltop, north and south facing slopes and valley bottom sites. Water and ground temperatures beneath the stream were also measured to provide information on the thermal influence of tundra streams on permafrost. Surface layer measurements consisting of vegetation height, active layer thaw depth and snow depth were acquired along cross valley transects. In addition, ground penetrating radar surveys were conducted to determine winter stream conditions at each site. This dataset improves the characterization of permafrost and environmental conditions at stream crossing sites where significant geotechnical challenges exist and provides useful baseline information necessary for the planning, design and regulation of infrastructure along the potential development corridor.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
