Electrical geophysics applied to assessing permafrost conditions in Pangnirtung, Nunavut
Bibliographic record
Abstract
As part of the project "Building Resilience to Climate Change in Canadian Communities" within the Climate Change Geoscience Program of Natural Resources Canada, electrical geophysical experiments were conducted in and around the hamlet of Pangnirtung, Nunavut in August 2009. Two-dimensional electrical resistivity imaging was performed in an effort to aid permafrost characterization and landscape hazard mapping efforts in the small Inuit community on Baffin Island. The electrical geophysical data were collected in conjunction with georadar data, geomorphologic mapping and shallow borehole drilling (see LeBlanc et al., 2010). The geophysical data are more extensive, spatially continuous, and provide deeper subsurface information than the mapping and drilling data. However, the geophysical data provide proxy measurements of geology and permafrost conditions, and are thus subject to interpretation and should be considered as complementary to other forms of terrain and permafrost assessment.

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.
