Modern observations of floccule ripples: Petitcodiac River estuary, New Brunswick, Canada
Bibliographic record
Abstract
Abstract Mud floccule ripples, small mud rip‐up clasts, erosional scars and tool marks are reported for the first time from the macrotidal Petitcodiac River estuary, New Brunswick, Canada. The ripples occur on the intertidal flats and are ebb‐oriented. Observations have been conducted during the spring low tide at high‐river and low‐river discharge. Floccule ripples forming during the high‐river flow are characterized by increased silt fraction, low relief and sinuous to lunate form. The ripples forming during the low flow are clay‐dominated, have very low relief and are characterized by narrow straight ridges and patchy distribution. The preserved mud floccule ripples manifest in interbedded silt‐rich and clay‐rich deposits with parallel, wavy, lenticular and current‐ripple lamination. Presented floccule ripples are current‐generated, non‐episodic in nature and are sedimentologically characterized. The ripple origin is constrained by morphometric and grain‐size analyses, and observed hydraulic processes. It is confirmed that mud floccule ripples originate under a similar range of hydraulic parameters as documented in previous flume studies. This study confirms application of work conducted in recent decades on mud‐dominated marginal‐marine environments and helps with understanding of properties and distribution of fine‐grained sediments in tidally influenced settings.

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.
