Supply Chain Narratives in the Salish Sea’s Transboundary Ecosystem: News Media and Public Positioning of the Roberts Bank Terminal 2 Expansion
Bibliographic record
Abstract
The Vancouver Fraser Port Authority’s proposed Roberts Bank Terminal 2 marine container facility in Delta, British Columbia, presents a narrative of economic opportunity and expansion for Canadian government and industry, and simultaneously has raised serious concerns in the transboundary Salish Sea watershed region about issues of sustainability, biodiversity, community impacts, and tribal rights. Ongoing media coverage of the yet-to-be-constructed project, which received federal government approval in April of 2023, has amplified the government’s economic justification for the maritime infrastructure. Yet numerous news outlets have simultaneously raised concerns over short- and long-term ecological deterioration and negative impacts to local communities. This two-pronged narrative underscores a disconnect between the aspirations of Canada’s federal government and the growing environmental concerns articulated by local and also transboundary constituencies in the Salish Sea watershed.

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.
