Abstract

fetched live from OpenAlex

This study was motivated by observations of significant salinification of the upper Eurasian Basin that began around 1989. Observational data and modeling results provide evidence that increased arctic atmospheric cyclonicity in the 1990s resulted in a dramatic increase of the salinity in the Eurasian Basin. Two mechanisms account for the Laptev Sea salinization: eastward diversion of Russian rivers and increased brine formation due to enhanced ice production in numerous leads in the Laptev Sea ice cover. Both these mechanisms are linked to changes in wind patterns and were essential to the formation of salinity anomalies. The resulting Laptev Sea salinity anomaly was advected to the central Eurasian Basin. The strong salinization over the Eurasian Basin altered the formation of cold halocline waters, weakened vertical stratification, and released heat upward from below the cold halocline layer. Our analysis suggests that local processes in the Laptev Sea may have a basin‐wide impact on the thermohaline structure of the Arctic Ocean.

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.
