Abstract

fetched live from OpenAlex

), resulting in faster rates for lighter crudes. However, photo-dissolution rates and importance to oil mass balance varied as a function of both reactivity and properties that govern slick thickness and light absorbance. Thicker slicks (∼1 mm) of light and heavy crudes produced more DOC by photo-dissolution compared to thin slicks due to higher rates of light absorbance. However, the mass lost from thin slicks (∼1 μm) was quantitatively relevant for calculations of oil mass balance, with a modeled ∼5% loss for a simplified, hypothetical spill after 1 day of sunlight exposure. The ULSFO was unusual in its exceptionally low photo-reactivity, suggesting distinct fates for this high-spill-risk product. The results show that photo-dissolution is a relevant fate process for a wide range of oil products and that it is controlled by oil properties and composition, making possible predictions of oil fate and effects for future spills at sea.

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.
