The Dynamic Response of Sea Ice to Warming in the Canadian Arctic Archipelago
Bibliographic record
Abstract
Abstract Ice arches in the Canadian Arctic Archipelago (CAA) block the inflow of Arctic Ocean ice for the majority of the year. A 22 year record (1997–2018) of Arctic Ocean‐CAA ice exchange was used to investigate the effect of warming on CAA sea ice dynamics. Larger ice area flux values were associated with longer flow duration and faster ice speed facilitated by increased open water leeway from the CAA's transition to a younger and thinner ice regime, which together have contributed to a significant ice area flux increase (10 3 km 2 /year) from Arctic Ocean into the northern CAA from 1997 to 2018. Remarkably, the 2016 Arctic Ocean ice area flux into the CAA (161 × 10 3 km 2 ) was 7 times greater than the 1997–2018 average (23 × 10 3 km 2 ) and almost double the 2007 ice area flux into Nares Strait (87 × 10 3 km 2 ). Continued warming may result in the CAA becoming a larger outlet for Arctic Ocean ice area loss.

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.
