Abstract
The spatial and seasonal variations in phytoplankton species composition and abundance in relation to physico-chemical properties were studied during Jan.-Dec. 1992. During the course of investigation, Biddulphiaceae, Coscinodiscaceae and Chaetoceraceae among Centrales and Naviculaceae among Pennales emerged as floristically rich families. A considerable variation was noticed with respect to the species assemblages of different months. Population density of phytoplankton showed conspicuous seasonal variations. The cell counts varied between 9-759 x 10 3 cells l -1 . Diatoms constituted the most dominant group followed by dinoflagellates. Occurrence of Asterionellopsis glacialis, bloom during April followed by the blooming of Peridinium sp. in May could be taken as the most striking feature of this study. Of the various environmental parameters studied, change in salinity and nutrient concentrations played major role in controlling the distribution and abundance of phytoplankton. Termination of bloom occurred due to depletion of silicate and nitrate from the water column.

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.
