Particle densities of wetland soils in northern Alberta, Canada
Bibliographic record
Abstract
Particle density is a fundamental soil physical property, yet values of soil and organic matter particle density (ρ s and ρ o ) vary widely in the literature. We measured particle density of organic soils from five wetland types, and from exposed sediments of drying ponds, in northern Alberta, Canada. Our measured values of organic soil and pond sediment ρ s varied widely (1.43–2.39 Mg m -3 ); however, calculated values of ρ o (1.34–1.52 Mg m -3 ) were relatively constant. The measured and calculated ρ s and ρ o values were similar to those obtained in published studies using similar methods, but were higher than the values provided in many reference texts. Given the relatively small variability in ρ o , the use of mean values of ρ o , combined with measurements of organic matter loss-on-ignition, shows promise as a simple method for obtaining reliable estimates of ρ s across a range of wetland types. Key words: Particle density, peat, organic matter, wetland soil, loss-on-ignition

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.
