Modelling long-term multi-species impacts from oil spill scenarios using Salish Sea Atlantis
Bibliographic record
Abstract
The Salish Sea is a major transportation route for oil between Canada and the USA. Continued oil transportation leads to concerns about the impact of spills on the surrounding ecosystem. Short-term impacts of oiling are more apparent and heavily studied, but the long-term effects of oil contamination throughout the ecosystem are not well known. A Salish Sea Atlantis whole-ecosystem model has been developed that allows us to explore the effects of contaminants on future trophic interactions. We used Atlantis, forced with time-series fields of water currents, temperature and salinity from the SalishSeaCast NEMO Model, to examine the impact of oil spills on key flora and fauna within the region. In collaboration with the Commonwealth Scientific and Industrial Research Organisation (CSIRO), here we present the results of specific oil spill scenarios developed in conjunction with the Department of Fisheries & Oceans Canada (DFO-Pacific) and Transport Canada. We focus on the potential long-term impacts of point source hydrocarbon contamination throughout the food chain. This includes groups of primary producers such as phytoplankton and seagrass, important fish species including salmon, as well as large mammals.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
