Abstract

fetched live from OpenAlex

Data collected off the southwest coast of India at the onset of the 1987 southwest monsoon season suggest that the commonly observed high concentrations of chlorophyll and rates of photosynthesis of the season may not be due to greatly enhanced chlorophyll-specific (normalized) photosynthetic rates of the bulk phytoplankton. Instead it is proposed that the seasonally increased nutrient supply primarily increases the growth rate of the otherwise more diffusion-limited large-celled species, which then can materially increase in numbers, since they are poorly controlled by grazers. If so, the principal role of the high nutrient concentrations would be to permit the build-up of a large algal biomass and pigment concentrations that, coupled with moderate normalized photosynthetic rates, yield the observed high production rates per m 3 and m 2 of the upwelling season.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
