Abstract

fetched live from OpenAlex

This paper presents a model for the evaluation of marine sites that utilize site specific spatial datasets in the estimation of ecosystem cumulative effects. The model is motivated by the evaluation of marine sites for aquaculture. Maps of the coastal zone of Grand Manan Island, New Brunswick in the Bay of Fundy along Canada's Atlantic coast are utilized for the purpose of illustrating the model. The data sets, processed as thematic layers in a Geographic Information System (GIS) describing the marine site, represent natural resource abundance, habitat inventory, valuations from economic and recreational activities, and influence plumes from sources of effluents. The valuation methodology assigns quantitative yields by layer-area of each selected site, as well as yields for the pairwise overlapping “cumulative effects” layers of the datasets based on defined yield impact functions. Results are presented that validate the model as an effective decision support tool for defining aquaculture sites of interest.

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.
