Abstract
A prototype instrumented tripod system designed for quantifying physical processes in muddy surfzone and nearshore regions was tested on tidal flats north of the Amazon River mouth. Physical data (i.e. wave characteristics, current velocities, suspended-sediment concentrations and characteristics) recorded during a 15-hr deployment at 1- 3.5 m water depth on this energetic, non-barred, fine-grained deposit demonstrate the value of this system to make field observations of sediment dynamics over an underconsolidated cohesive boundary. Significant sediment transport is occurring via resuspension of fine-grained particles and aggregates by wave-induced velocities up to 100 cm sec -1 . Tidal currents (0-35 cm sec -1 ) are shorenormal with a low-frequency (residual) component advecting material alongshore. Physical data are supported by simultaneous coring which allows documentation of reworking for the uppermost over a semi-diurnal tidal cycle. A fluid-mud layer (< 10 cm) thick covers the seabed and changes in density and thickness with varying benthic shear stress, Muddy deposits accumulating in this setting are composed of physically stratified laminations of silt/clay (µ - to cm-scale).

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; both teacher heads agree on what is shown here.
