Abstract
Abstract Snow tube samplers are the primary method of measuring snow water equivalent (SWE) in the field, as they are considerably less destructive to the snowpack and faster to use than traditional snow pit techniques. This study evaluates the performance of three commonly used snow tube designs: Standard Federal, Meteorological Service of Canada (MSC), and SnowHydro. The Standard Federal and MSC designs have previously been extensively tested; however, the SnowHydro is a new design for which an error analysis has not yet been published. We compared the three designs in a shallow, highly stratified snowpack in both a forest and a clearcut, conditions that are not well represented in previous studies. While the Standard Federal produced SWE values closest to snow pit measurements, the SnowHydro snow tube outperformed the other two designs in terms of coring performance and produced more consistent SWE measurements. Although this is the first published study to quantify the performance of the SnowHydro sampler, additional studies under varying snow conditions are required to adequately quantify sampling errors.

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
