Abstract

fetched live from OpenAlex

Water quality in remote lakes on the east side of Lake Winnipeg was largely unknown. This study was the first attempt at characterizing the baseline conditions in a large number of lakes on the east side of Lake Winnipeg. Water quality of up to 99 boreal shield lakes was sampled by floatplane in 2004 and 2005. Standard physical and chemical water quality data were collected for each lake. Water quality in this region was affected by characteristics of the watershed such as soil type, the proportion of wetlands in the watershed, and forest type. Watershed disturbance such as forest fire and forest harvesting appeared to have a marked influence on water quality. Forest harvesting disturbance and to a lesser extent fire disturbance was associated with the most eutrophic lakes. However, the most dramatic differences compared to reference sites appeared to only occur when a larger proportion of a watershed had been disturbed. The data indicated that if watershed forest harvesting had an impact on water quality it appeared to be of longer duration than that of forest fire.

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.
