A non-invasive investigation of polythermal glacial hydrology: Stagnation Glacier, Bylot Island, Nunavut, Canada
Bibliographic record
Abstract
In comparison to temperate examples, there are relatively few studies to date focused on the hydrology of polythermal glaciers. In particular, seasonal evolution of hydrological architecture at high latitude glaciers is poorly understood, with exception of a number of recent hydrochemical and dye tracing analyses. However, contemporary research has shown ground penetrating radar (GPR) to be effective tool for imaging englacial structures. To investigate seasonal evolution of englacial, subglacial and ice-marginal hydrology at the informally named Stagnation Glacier, Bylot Island, Nunavut, repeated sub-surface surveys using GPR were conducted, complemented by dye tracing and analysis of proglacial instream sediment transport. Results from all three methods strongly indicated progressive, yet subtle development of a polythermal glacier's hydrology through the summer. This work documents structural thermo-hydrologic progression at a polythermal glacier, and the integration of results, and interpretations presented here have potentially significant implications for the conceptual understanding of Arctic glacial hydrology, including water pressure distribution.

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; a candidate call from one teacher head, not a consensus.
