Deep groundwater circulation through the High Arctic cryosphere forms Mars-like gullies
Bibliographic record
Abstract
We report here the discovery of the northernmost known perennial spring, located in the polar desert of the Canadian High Arctic (average precipitation 75.5 mm/yr; average annual air temperature 19.7 C). The high-discharge spring (∼520 L/s) has also anomalously high temperatures (9.0 C), despite occurring in a region of low geothermal gradient and thick (>400 m) permafrost. Active erosion at the spring outlet forms gullies with alcove-channel-apron morphology, remarkably similar to archetypal gullies observed on mid-latitude regions of Mars. Geochemical and isotopic data show a meteoric origin for the waters, demonstrating that deep circulating groundwater systems can form active connections through the cryosphere to the subsurface, even in the absence of thermal anomalies. This discovery challenges current understanding of high-latitude permafrost hydrology.

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.
