Abstract
The purpose of this study is to document the magnitude and variability in surface sediment deposition in salt marshes along the New Brunswick coast of the Bay of Fundy. We measured the thickness of sediment accumulated over clay marker horizons for the period of one year. Sediments were sampled at seven sites from the head of the Bay to the outer Bay, distributed to span a gradient in tidal range (6-12 m). Within each marsh sample plots were located to control for relative elevation, distance from vegetated edge, and vegetation zone. Accumulated sediment was greater than 4 cm on some plots. Sediment accumulation generally decreases with relative elevation and distance from vegetated edge within marshes and increases with tidal range, which tends to co-vary with suspended sediment concentration. We conclude that changes in sediment supply will have the greatest impact on low marsh accretion while changes in sea level or marsh hydrology will be most important to high marsh accretion.

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
