Abstract
The California Undercurrent is known to transport relatively warm, high‐salinity, nutrient‐rich water from the equatorial Pacific to Vancouver Island along the western continental slope of North America. This transport helps maintain the high productivity of the eastern boundary California Current system. In this study, we use several decades of water property survey data for the coasts of Oregon, Washington, British Columbia, and Alaska to show that equatorial Pacific water carried poleward by the undercurrent can eventually reach the Aleutian Islands, roughly 11,000 km from the source region. Long‐term current meter records confirm the undercurrent as far north as Vancouver Island, where the current is found to be weakest in spring but then to strengthen through the summer and fall before merging with the wind‐forced, poleward flowing Davidson Current in winter. The core depth of the equatorial water increases from 150 m ± 25 m off northwest Washington (near the northern end of the western North America coastal upwelling domain) to 225 m ± 25 m off southeast Alaska (near the southern end of the Gulf of Alaska coastal downwelling domain).

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 it
