Time-domain electromagnetic data for the Spiritwood valley aquifer, Manitoba
Bibliographic record
Abstract
This Open File reports on recent time-domain electromagnetic geophysical data collected and processed by the Geological Survey of Canada as part of the Aquifer Assessment and Support to Mapping project within the Groundwater Geoscience Program. A 1062 km2 area of the Spiritwood valley aquifer in southern Manitoba has been developed as a site for testing the application of airborne electromagnetics and other surface and downhole geophysical methods for regional mapping and characterization of buried valley aquifers in Canada. In November of 2013, time-domain electromagnetic soundings were performed at selected sites to better constrain the airborne results. One-dimensional modelling and inversion of the data show marked variability in the data and the resistivity models between different geological settings. In particular, depth to bedrock is clearly resolved in the models and the incised buried valley interpreted from the regional airborne survey is associated with a relatively strong resistive anomaly indicative of coarser grained material or a high-potential aquifer.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
