Time series analysis of atmospheric mercuryin Kuujjuarapik/Whapmagoostui (Québec)
Bibliographic record
Abstract
Recent mercury depletion events observed in the Arctic have opened the horizon to numerous new aspects on mercury fate and cycling in the environment. Total Gaseous Mercury and other Atmospheric Mercury speciations are measured in Kuujjuarapik/Whapmagoostui (Lat.: 55.30°N; Long.: 77.73°O) along the Hudson Bay (Québec) with Tekran 2537A, 1130 and 1135 units. The former is measured since August 1999 whereas the latter are measured during springtime periods over the last three years. Mercury Depletion Events are observed at this low latitude région. MDEs are observed between February and April and are occurring during both the day and nighttime periods. Typically, MDE in Kuujjuarapik are related to air temperature. During MDEs, a significant speciation conversion from Hg, to RGM and TPM is operating. However, ratios of TPM to RGM conversion are variable in time.

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.
