Benthic fauna in Hamilton Harbour and adjacent Lake Ontario 2002–2005 in comparison to 1964
Bibliographic record
Abstract
The benthic fauna of Hamilton Harbour was surveyed in 2002–2003, with additional sampling in adjacent Lake Ontario in 2005. Oligochaetes were dominate, with high densities at both 1.7 m depth and in the middle of the harbour at 23 m. Chironomids density was 410 to 6800 m-2 above 9 m depth, but very rare below 9 m. The benthic community was limited to species tolerant of severe eutrophication, with non–oligochaete taxa rare below 8 m depth. Typical littoral gastropods, amphipods and non-chironomid insects were very rare. Diversity ranged from 0.2 on the south side to a maximum of 2.5 near the north shore. Periodic low oxygen limits the benthic community in large areas of the harbour. Limited nearshore habitat and contaminated sediments restrict the community in other parts of the harbour. Total density was low along the exposed western Lake Ontario shoreline, but diversity was high.

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; both teacher heads agree on what is shown here.
