Abstract
Investigations into the occurrence and concentrations of hydrogen sulphide in sediments of the Gulf of Gdansk were carried out in September 1994. It was found that the concentration of H2S increased with basin and sediment depths. The highest concentration (1244 μmol dm) was recorded in the 4–8 cm sediment layer at the deepest of the stations investigated (station 14; 82 m depth). The studies demonstrated that numerous species belonging to the macrozoobenthos are exposed to H2S concentrations from several to several hundred μmol dm . These are both deep-water species – Macoma balthica, Harmothoe sarsi, Saduria entomon, Pontoporeia femorata – and shallow-water species – Corophium volutator, Mya arenaria. High concentrations of hydrogen sulphide, i.e. > 1000 μmol dm, caused the number of different macrozoobenthos species to decrease, even though abundance and biomass levels remain high. The studies indicated that the presence of hydrogen sulphide is best tolerated by two species – Macoma balthica and Harmothoe sarsi.

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.
