Plastic pollution within "The Gully" Marine Protected Area of the Scotian Shelf, Northwest Atlantic
Bibliographic record
Abstract
This dataset contains information on plastic particle densities, characteristics (colour, morphology), size, and polymer types collected from seawater in "The Gully" Marine Protected Area between 1990 and 2019. Also included are the characteristics, sizes, and polymer types of ingested debris removed from the stomachs of two Endangered northern bottlenose whales (Hyperoodon ampullatus) stranded in Canada in 2019 and 2021. These data appear across 4 tabs in a single .xlsx file, connected by a SampleID column. Please see the following publication for full details: Kelly, N.E., Feyrer, L., Gavel, H., Trela, O., Ledwell, W., Breeze, H., Marotte, E.C., McConney, L. and Whitehead, H., 2023. Long term trends in floating plastic pollution within a marine protected area identifies threats for Endangered northern bottlenose whales.

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.
