Holocene Sedimentary Environments of the Goat Meadows Watershed, Southern Coast Mountains, British Columbia
Bibliographic record
Abstract
This paper presents the results of an investigation of Holocene erosion and sedimentation in a small subalpine watershed in the southern Coast Mountains of British Columbia. The study involved determinations of the volume and mass of lake sediments accumulated during each of four time periods (10,510-6700 BP; 6700-6340 BP; 6340-2400 BP; and, 2400 BP to the present); analysis of physical, chemical and mineralogical properties of the sediments and palaeoenvironmental interpretations of erosion and sedimentation rates, sediment sources and organic productivity. Indications are that the paraglacial period was complete by ca. 10,000 BP and that there followed a period of low sedimentation (10,000-6700 BP); higher sedimentation rates determined for the period 6700-6340 BP may reflect accelerated rates of erosion during the warmer/drier xerothermic interval. Rates declined again during the period 6340-2400 to be followed by higher rates in the most recent period (post 2400 BP). It is hypothesised that progressively cooler and wetter conditions have activated the older weathered slope materials. Analysis of slope sediments is consistent with this hypothesis.

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.
