63. Hydrological and Biological Event Based Variability in the Fine-Grained Sediment Structure of a Small Undisturbed Catchment
Bibliographic record
Abstract
In 2001 a study in an undisturbed, highly productive salmon bearing stream (O'Ne-eil Creek) was undertaken in the northern interior of British Columbia, Canada. The aim was to determine if the structure and settling characteristics of the aggregated sediments varied significantly over the different hydrological and biological regimes of an open-water season. Sampling regimes included the hydro- logical conditions of the rising limb of spring freshet, falling limb flows of snowmelt and summer rainstorms, while biological conditions included sampling during spawning and die-back of 13 580 sockeye salmon. A negative relationship between shear stress and effective particle size diameter, D50 is evident for the hydrological regimes, while the largest floes occur when live and dead salmon are present in the stream. Increased organic matter quality and biological resuspension of gravel-stored material attributed to spawning salmon, reflect their physical and chemical influence on the change in size and density of aggregated fine sediment in this stream system.

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.
