Abstract
The presence of mercury (Hg) is increasing in Arctic region and the Arctic sea will take short time to reflect changes in atmospheric Hg levels. Hence, monitoring of mercury content in the environmental matrices of Arctic is highly significant. The present study assessed the total mercury (THg) as well as various Hg fractions in the sediments of Kongsfjorden, an Arctic Fjord in Svalbard. The Hg toxicity mainly depends on the form which occurs. Fractionation study will help to understand the different forms of Hg in sediment samples. The mean concentration of THg in sediment was 485 ng/gm dry weight. The results of fractionation indicated the mobility of Hg in the Kongsfjord sediments. The highest percentage of Hg was in fourth fraction (F4) followed by the fractions F2, F1, and F3 and final fraction (F5). The high Hg concentration in the initial fractions indicated the availability of Hg for chemical and biological transformations and transport in the Fjord. Hence potential toxic effects are possible in the system.

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 it
