Abstract
Sapropels, i. e. discrete, black and organic-rich layers sedimented in the Eastern basin in anoxic conditions, constitute record, over the past 500,000 years, of eleven particular interactions between marine circulation and biology during glacial as well as temperate climates. Considering climatic and dynamic aspects, we argue that this formation is preconditioned by the stoppage of dense water formation in the Adriatic Sea, following sea-level and/or freshwater input changes. In this case, oxygenation of eastern deep water depends solely on the dense water formation in the South Aegean Sea, a process modified by episodic freshwater inputs. This scheme explains correlations between sapropel events and the strong African monsoons responsible for Nile river flooding over several thousand years (Rossignol-Strick, 1983). At the time of sapropel formation, Mediterranean general dynamics and planktonic productivity were not drastically changed. The deciphering of Mediterranean climatic records needs to take into account northern ice sheet changes (via sea-level, temperature and salinity in the adjacent Atlantic), as well as tropical climatic oscillations (via increased freshwater inputs and sapropel events).

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.
