Helicopter time-domain electromagnetic data over the Eastern Hatfield buried-valley aquifer system, Saskatchewan
Bibliographic record
Abstract
Buried-valley aquifers occur across the Canadian Prairies with a lack of surface expression and complicated network geometries. As part of an effort to map and characterize the Hatfield buried-valley aquifer, the Geological Survey of Canada commissioned a helicopter time-domain electromagnetic survey consisting of 2617 line-km of data over 940 km2 near Esterhazy and Rocanville in southeastern Saskatchewan. Survey results are presented as apparent-conductivity maps and as 3D conductivity-depth models. The Hatfield and Rocanville buried valleys are clearly imaged along with several other erosional and depositional features, some of which have been previously identified at the local scale and are currently utilized as groundwater resources, but for which the extent has not been fully mapped. Other features identified in the survey represent potentially new groundwater resources and can be used to help unravel the details of valley formation, groundwater flow, and aquifer recharge.
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.
