Abstract

fetched live from OpenAlex

Ocean waves can generally increase the initial dilution of produced water andsubsequently affect the ecological risk. To study the wave effects on ecological risk, aprobabilistic based buoyant jet dispersion model has been in tegrated with risk analysissoftware. @ RISK, to assess ecological risk for a case corresponding to publishedparameters for the White Rose field, off west coast of Canada. The ecological risks onsheepshead minnows were evaluated by conducting Monte Carlo simulation for fourdifferent discharge scenarios. The Hazard Quotients (HQs) method was used tocharacterize the risk. Contour plots of probability distributions of (HQs) from those fourdischarge scenarios were compared and discussed. The wave effects were identified by comparison of the wave and no wave simulations.

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.
