Abstract
The nature of the physical regime in the vicinity of the Rhine ROFI (Region Of Freshwater Influence) has been determined in a series of collaborative observations. Extensive surveys with shipboard CTD/rosette systems have been used to complement time series observations by an array of moorings instrumented with currentmeters, transmissometers and fluorimeters. The observations reveal a highly variable system in which the influence of the freshwater input from the Rhine extends northeastwards from the source and out to 30 km from the coast. The mean flow within this region is generally parallel to the coast (northeastwards) and with surface speeds, determined by the HF radar, of 15-20 cm.s-1. The residual current at sub-tidal frequencies was strongly correlated with windstress-forcing with a transfer factor of approximately 1 %. Water column structure exhibits marked periodic variations particularly on semi-diurnal and semi-monthly time scales, the latter highlighted by contrasting post-springs and post-neaps surveys of the ROFI region. Springs tidal stirring was reinforced by strong wind (and wave) mixing which brought about complete vertical homogeneity everywhere except at the Rhine mouth. After the following neaps, and a period of light winds, the water column was observed to have re-stratified over the whole inshore region through the relaxation of the horizontal gradients under gravity and with the influence of rotation as in the model of Ou (1983). The switching of the water column regime between stratified and mixed conditions was observed to markedly change the coupling between low frequency surface and bottom currents and is also reflected in the suspended sediment variations. Generally high levels of seston throughout the coastal boundary layer in the post-springs period were followed by a dramatic reduction especially in the region which re-stratified. An interesting exception was the combined occurrence of high turbidity and low salinity in surface waters due to the immediate influence of the Rhine outflow near the source.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
