Fluvial response to late Holocene glacier fluctuations in the Nostetuko River valley, southern Coast Mountains, British Columbia
Bibliographic record
Abstract
Late Holocene glacier fluctuations and changes in bed elevation are recorded in the alluvial fill of the west fork Nostetuko River valley, southern Coast Mountains, British Columbia. Valley-wide aggradation coincides with periods of local and regional glacier advance on centennial timescales. Peat layers containing in situ tree roots and stumps formed during periods of floodplain stability that coincide with intervals when glaciers were restricted. Radiocarbon ages on roots, tree stems, and woody plant detritus in the peat layers record five major phases of Holocene glacier advance, the most recent at the culmination of the Little Ice Age. A high-resolution record of Little Ice Age glacier fluctuations was derived by cross-dating ring-width series of fossil trees in the peat layers with a previously established master ring-width chronology and by constraining floating ring-width chronologies with radiocarbon ages.
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.
