Glacier status and contribution to streamflow in the Olympic Mountains, Washington, USA
Bibliographic record
Abstract
Abstract The Olympic Peninsula, Washington, USA, currently holds 184 alpine glaciers larger than 0.01 km 2 and their combined area is 30.2 ± 0.95 km 2 . Only four glaciers are >1 km 2 and 120 of the others are <0.1 km 2 . This represents a loss of 82 glaciers and a 34% decrease in combined area since 1980, with the most pronounced losses occurring on south-facing aspects and in the more arid northeastern part of the range. Annual rate of loss in glacier area for seven of the largest glaciers accelerated from 0.26 km 2 a −1 (1900–80) to 0.54 km 2 a −1 (1980–2009). Thinning rates on four of the largest glaciers averaged nearly 1 ma −1 from 1987 to 2010, resulting in estimated volume losses of 17–24%. Combined glacial snow, firn and ice melt in the Hoh watershed is in the range 63–79 ± 7 × 10 6 m 3 , or 9–15% of total May–September streamflow. In the critical August–September period, the glacial fraction of total basin runoff increases to 18–30%, with one-third of the water directly from glacial ice (i.e. not snow and firn). Glaciers in the Elwha basin produce 12–15 ± 1.3 × 10 6 m 3 (2.5–4.0%), while those in the Dungeness basin contribute 2.5–3.1 ± 0.28 × 10 6 m 3 (3.0–3.8%).

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.
