Anomalous subarctic influence in the southern California Current during 2002
Bibliographic record
Abstract
A highly anomalous water mass of apparent subarctic origin, characterized by negative temperature and salinity anomalies, high concentrations of dissolved oxygen and inorganic nutrients, and unusually high chlorophyll fluorescence, was observed off southern California during summer 2002. This water mass was confined spatially to a narrow ribbon in the upper pycnocline: at a density of σ t = 25.0 kg m −3 and ∼150–350 km offshore, within and seaward of the main California Current core. These observations are very similar to those made off the Oregon and Vancouver Island coasts at about the same time, implying a displacement of subarctic waters more than 1200 km equatorward within the California Current. The maintenance of strong water property anomalies over this distance demonstrates the efficacy of the California Current as a conduit of water masses and plankton. The magnitude of the anomalies observed in July 2002 suggest the occurrence of the largest subarctic intrusion into the California Current System in the 50+ year historical record and may reflect low‐frequency climate variability.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
