Monitoring the dispersion of an intentionally released tracer, SF<inf>5</inf>CF<inf>3</inf> with an instrumented, unmanned surface vehicle
Bibliographic record
Abstract
We describe the physical and operational characteristics of an autonomous platform for ocean observation which has considerable potential for tracer dispersion and gas exchange studies. The Dorado (International Submarine Engineering, Port Coquitlam, B.C.) is an 8.2 m long, 1.2 m in diameter, snorkelling, semi-submersible vehicle powered by a 315 kW Caterpillar marine diesel engine. Capable of cruising at 8 m s-1(16 knots) for sustained periods of up to 28 hours, the vehicle's linear range is on the order 1 × 103km. We further describe plans for the Dorado's maiden scientific voyage. The vehicle will be equipped with a novel, compact, unattended GC and membrane-based equilibrator, as well as, supporting instrumentation. The vehicle will be used to monitor the dispersion of the deliberate tracer, SF5CF3, following a surface injection on the Scotian Shelf during the summer/fall of 2016. The analytical system will be tuned for the detection of the SF5CF3and SF6.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
