Abstract
Abstract: This paper presents results from measurements of the intensity of sand transport by wind on the beach and stoss slope of a vegetated foredune over one day, at Greenwich Dunes, Prince Edward Island, Canada. Measurements of wind speed and direction were made with arrays of cup anemometers and 2-D sonic anemometers. Sediment transport intensity was measured at a height of 2-4 cm above the bed using 6 Sabatech omnidirectional saltation probes which count the impact of saltating grains on a piezoelectric crystal. Individual sensors appear to provide a consistent response to fluctuating sand transport. Where there is a considerable supply of dry sand the saltation system responds very rapidly (1-2 seconds) to fluctuations in wind speed- i.e. to wind gusts. Where sand supply from the surface is limited by moisture or by the presence of vegetation, mean transport rates are much lower and this reflects both a reduction in the instantaneous transport rate and in a transport system that becomes increasingly intermittent. While at this stage the saltation probes cannot provide a reliable estimate of the total sediment flux, they do provide a useful insight into the nature of the transport

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
