Abstract

fetched live from OpenAlex

Over the past decade there have been dramatic reductions in the areal extent of sea ice in late summer over the Arctic Ocean. For sub-regions in the western Beaufort Sea (off Alaska) and the deeper offshore waters of the Canadian sector of the Beaufort Sea, the trend towards reduced total ice concentrations in late summer ranges from -11.4 and -7.3% per decade, respectively, which is comparable to the reduction of -11.1% per decade in overall Arctic Ocean during late summer. In the central Canadian Arctic sub-regions through the Northwest Passage, the trends in total ice reduction are smaller at +1 to - 6 percent per decade. The trends computed for old ice can be quite different from that of total ice concentrations. In the western “chokepoint” area of the Northwest Passage (Viscount Melville Sound), the late summer trend is -6% per decade and +2.5% per decade for total and old ice, respectively. The trends in the long-term sea-ice thickness measurements in the Beaufort Sea over the continental shelf and in the eastern portions of the Canadian Arctic do not show major reductions unlike measurements from the deepwater Arctic Ocean.

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.
