Abstract

fetched live from OpenAlex

Continuous plankton recorder data for phytoplankton color index, total diatoms, Calanus finmarchicus stages 1–4 and 5–6, C. glacialis, C. hyperboreus, and Paracalanus–Pseudocalanus spp. collected between the years 1961 and 1998 in the Canadian Atlantic region were analyzed for geographic and temporal changes. Significant differences in both geographic and temporal scales were detected. Changes were observed in all taxa during 1991–1998 with the phytoplankton color index increasing significantly (P = 0.05). A shift in the climatology occurred after 1991 as concentrations of C. finmarchicus and Paracalanus–Pseudocalanus became significantly higher (P = 0.05) in the first 3 months of the year compared with the years 1961–1974. Multiple linear regressions calculated between various biological taxa and the storm, temperature, and stratification indices showed that these physical indices explained between 21 and 51% of the multiple regression variance.

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.
