Application of geosynthetic barrier wall to containment of hydrocarbons in the Arctic
Bibliographic record
Abstract
The effect of freeze-thaw cycles on the hydraulic conductivity of a geosynthetic clay liner (GCL) is assessed with respect to Jet Fuel A-1 (Arctic diesel). GCL specimens subjected to 0 and 5 freeze-thaw cycles and specimens recovered from a site on Brevoort Island in the Canadian Arctic after 3 years are examined. The GCL recovered from Brevoort Island had the lowest hydraulic conductivity with respect to de-aired water. Freeze-thaw cycles did not have a negative impact on hydraulic conductivity with respect to de-aired water. Freeze-thaw cycles did increase the hydraulic conductivity, k, with respect to Jet Fuel A-1. However, the hydraulic conductivity was still very low and the results suggest that the GCL can be expected to perform well as a hydraulic barrier in the medium term with respect to the effects of both freeze-thaw and permeation with Jet A-1. More testing is needed to assess long term performance.

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.
