Abstract

fetched live from OpenAlex

Abstract A long-term proxy record of glacier mass balance was developed for Colonel Foster and Septimus glaciers on Vancouver Island, British Columbia, Canada. This was accomplished by analyzing the radial growth characteristics of climatically-sensitive mountain hemlock trees (Tsuga mertensiana), and by comparing this response with mass balance records from four glaciers in the Pacific Northwest. A strong (negative) relationship between the two records for the period 1966–1994 provides the basis for a mass balance reconstruction extending back to 1600. The reconstruction is in general agreement with information derived from dated moraine sequences at the two glaciers on Vancouver Island, and it has potential applicability to glaciers in adjacent areas of coastal Pacific North America. Our results highlight the likely influence of the Pacific Decadal Oscillation (PDO) on glacier dynamics during the mid- to late-Little Ice Age (LIA) and provide the groundwork for long-term glaciohydrologic studies.

Full frame distilled prediction

Teacher imitation

Not 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.
