Abstract

fetched live from OpenAlex

Nares Strait, situated between northwest Greenland and Ellesmere Island is a major sea ice export path from the Arctic Ocean. One of the narrowest parts of the strait --- Kennedy Channel --- is host to several islands. These obstacles' impact on the ice flow along the Strait has yet to be investigated. Here we show that during autumn, these islands can interrupt the relatively homogenous sea ice flow through Kennedy Channel, carried by wind and water currents, and shield downstream regions from becoming ice-covered, resulting in the formation of hitherto unknown transient polynyas, whose size and extent were correlated with the wind's strength and direction along Kennedy Channel. These polynyas likely impact the regional meteorology and oceanography through enhanced air-sea fluxes of heat, moisture, momentum, and carbon dioxide. The presence of open water may also impact the complex and productive regional ecosystem.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
