Abstract
Ocean current direction measurements through the Canadian archipelago have required development of a strategy that uses specialised instrumentation to cope with the small horizontal component of the earth's magnetic field in this region. Subsurface instrumented moorings collecting bihourly data through yearlong deployments, use precision heading reference systems to measure the orientation of Acoustic Doppler Current Profilers mounted in streamlined buoyancy packages. Current directions are then corrected for the significant fluctuations in magnetic declination occurring near the magnetic pole, using data from a nearby geomagnetic observatory. Concurrent observations of current speed and direction from independent moored measurement systems are shown to be in good agreement. KEY WORDS: current direction measurement, low magnetic field, polar, Arctic mooring instrumentation, magnetic pole

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
