Chemical Characteristics and Seasonal Variation of Snow on Urumqi Glacier No.1 of the Eastern Tianshan,China
Bibliographic record
Abstract
Alpine glacier and snow can record signals of surface earth.From September 2002 to October 2005,Surface snow samples were collected on Urumqi glacier No.1 and chemical characteristics and seasonal variations of major ions,dust,and metal were measured.Results show that the concentration of major ions is Ca2+SO2-4NO-3Cl-NH+4Mg2+Na+K+,Ca2+ is the dominant cation,SO2-4 is the dominant anion.All ions have good correlation except NO-3.δ18O shows minus correlation with air temperature change.Dust and major ionic concentrations in the snow show obvious seasonal change trend,with higher concentrations in spring but lower ones in summer,which indicates the chemical input of dust activities to snow.Temporal changes of heavy metal(Cd,Pb,Zn,Al,Fe) indicate that human activities also have effect on the snow chemistry.

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.
