Abstract
Since 1991 personnel from the Bedford Institute of Oceanography have been using helicopter-borne Electromagnetic Induction sensors to measure sea ice thickness distributions. To fill the gap between timeconsuming ice measurements through auger ice holes and long-transect profiles lines collected along helicopter-borne sensors, a miniature Electromagnetic Sensor mounted on a sled was tested in 2008 during the IPY’s Circumpolar Flaw Lead Experiment. Real time GPS location and ice thickness data were collected by the EM Sled at 1sec intervals and compared to measurements obtained through ice holes. Good agreement between auger and EM thickness were found along two calibration lines of 170cm and 70cm thickness located on a mobile pack ice floe in the eastern Canadian Beaufort Sea.

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
