Radium and radon in massive ice, groundwater, seawater, and sediments in the Northwest Territories, Canada, 2019
Bibliographic record
Abstract
Rapid warming in the Arctic is degrading permafrost and massive ice deposits, which releases solutes previously trapped in ice and frozen soils into groundwater, rivers, and the coastal ocean. Radium (Ra) and radon (Rn) isotopes are enriched in groundwaters and may therefore have utility as tracers for the delivery of permafrost-derived solutes to the ocean, particularly if massive ice- or permafrost- derived meltwaters have a distinct isotopic ratio. Radioactive (radium, radon) and stable (oxygen-18) isotopes were measured in massive ice, permafrost, groundwater, surface waters, and sediments on Tuktoyaktuk Island and Peninsula Point in the Northwest Territories, Canada, with the goal of identifying the isotopic signature of the massive ice endmember. To our knowledge, this is the first dataset that reports radium and radon activities in massive ice deposits.

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.
