Decadal changes in phytoplankton color index and selected calanoid copepods in continuous plankton recorder data from the Scotian Shelf
Bibliographic record
Abstract
Continuous plankton recorder data for phytoplankton color index, total diatoms, Calanus finmarchicus stages 14 and 56, C. glacialis, C. hyperboreus, and ParacalanusPseudocalanus 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 19911998 with the phytoplankton color index increasing significantly (P = 0.05). A shift in the climatology occurred after 1991 as concentrations of C. finmarchicus and ParacalanusPseudocalanus became significantly higher (P = 0.05) in the first 3 months of the year compared with the years 19611974. 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.

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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
