High frequency acoustic observations of episodic mixing events in Lunenburg Bay
Bibliographic record
Abstract
High frequency backscatter observations recorded through acoustic current profilers and velocimeters at three locations within the Lunenberg Bay were analyzed. It was found that six periods of enhanced surface-intensified backscatter and three periods of enhanced scattering near the bottom occurred between 260-290 days. Local sheltering of wind and waves resulted in distinct data sets from each location for any given period of enhanced scattering to varying degrees. Wave height estimates were made using the data from the internally recording ADCP, which was equipped with a waves measurement package and calculated a spectrum every half hour, using 20 minutes of data sampled at 2 Hz. Wind speed measurements were made using a shore based anemometer on a 10m tower, which were reported every hour. The results show that the event at day 272, which was the focus of the preliminary investigations of the periodic events, corresponds to the arrival of Hurricane Juan at Halifax, NS.

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.
