A review of Hamilton Harbour beaches: Towards delisting 2020, successes and challenges
Bibliographic record
Abstract
Bayfront and Pier 4 Beaches are located in Hamilton Harbour, Ontario, Canada. Both beaches experienced health advisory postings >60% of the bathing season prior to 2005. In order to de-list Hamilton Harbour as one of 43 areas of concerns, the water quality at Bayfront and Pier 4 Beaches must meet the provincial water quality objective of 100 cfu of Escherichia coli 100 ml−1 > = 80% of the bathing season for a minimum of three consecutive years. In 2005, the Hamilton Harbour Beach Committee was formed to guide beach managers on decisions pertaining to beach remediation and E. coli mitigation. Here we discuss the various studies, projects and public outreach programs delivered by Environment Canada, the City of Hamilton and the Bay Area Restoration Council to improve beach health and move toward delisting as an Area of Concern by 2020.

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.
