Abstract
A large number of several-month current time series is now available in the western Mediterranean Sea, and harmonic and spectral analyses provide spatially coherent information about the major tidal (M2, S2, N2 and K1) currents in the region. When they are significant, these currents are generally barotropic, they mainly rotate clockwise and their ellipses have orientations that are strongly dependent on the local bathymetry. From the Alboran Sea to the Algerian Basin, the Ibiza Channel and as far as the Sardinian Channel, the velocities of the semidiurnal components continuously decrease from a few 10(-2) m/s in the west to 10(-3) m/s and even less in the east. The phases increase eastward from the Alboran Sea to 3-4 degrees E in the western Algerian Basin, and can then be considered as constant as far as similar to 9 degrees E in the Sardinian Channel. Such a phase variation is consistent with numerical models and results from the presence of an amphidromic zone near 0-2 degrees E. Eastward of similar to 9 degrees E, the phases should increase again, under the influence of another amphidromic zone located in the Sicily Channel. In both the Gulf of Lions and the Ligurian Sea, the velocities are extremely low and the ellipse characteristics are erratic, again in agreement with the models. In the Corsican Channel, where relatively shallow depths induce an increase of barotropic currents, the semi-diurnal components have a phase roughly opposed to that in the southwestern part of the sea. Considering the amphidromic zone in the Sicily Channel, this out-of-phase relationship is consistent with the occurrence of a zone of maximum elevation in the eastern Tyrrhenian Sea. The K1 currents in the Corsican Channel are lower than the M2 ones, but much larger than any other tidal current. They are exactly in phase with the elevation in the whole sea. All these results also prove that low tidal currents can be discerned in records made by simple instruments.

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.
