Benthic diatom communities from rivers in close proximity to the Athabasca tar sands (Alberta, Canada)
Bibliographic record
Abstract
This project was undertaken to study diatom communities from rivers in close proximity to tar sands development in the Athabasca River watershed, Alberta, Canada. Over the past years, tar sands development in Alberta has been intensified and presents new challenges for environmental management in Alberta. As the predominant technologies for extracting bitumen from the tar sands rely on large amounts of freshwater, concerns on the water quality of natural water bodies and its impacts on aquatic life and human health are increasing. Although limited information on the diatom communities in this region is available from the late 1970s and early 1980s, there are no reference diatom communities with which to compare modern-day samples. In this study, water and diatom samples were collected from nine sites in 2008 and replicate samples were collected from a subset of those sites in 2009. Based on the few samples available, it was not possible to directly link tar sands-related pollution with changes in diatom community structure, although diatoms clearly showed a response to dissolved organic carbon (DOC) and conductivity. However, diatom communities collected represent a benchmark for biomonitoring assessment in the region following expansion of the industry and represent valuable information for future studies.

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.
