Impacts of retrogressive permafrost thaw slumps on aquatic systems in the Peel Plateau, Northwest Territories, Canada
Bibliographic record
Abstract
Along the slopes of the Richardson Mountains, west of the Mackenzie Delta in the Northwest Territories of Canada, the stratigraphies of two lakes with large retrogressive thaw slumps within their catchments are examined using paleolimnological techniques.The lacustrine geomorphological impacts of current thaw activity are examined, as well as the past occurrence of large-scale thermokarst disturbances.Sediment stratigraphies from the larger lake suggest repeated erosion through time.The sediment stratigraphy from the smaller lake records ~55 cm of deposition due to thaw slump activity in the past 20 -40 years.Aside from the recent thaw slump activity recorded in the smaller lake basin, neither system provided discernable evidence of long-term, ancient slump activity.The difference in the magnitude of impacts of the two systems is primarily attributed to catchment area to lake area and disturbance area to lake area ratios.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
