Environmental Characterization for the RDS-4 Experiment in the Halifax Harbor Approaches and Emerald Basin
Bibliographic record
Abstract
The RDS-4 sea trial is the fourth in a series of trials sponsored by TTCP MAR TP-9 on the topic of Rapidly Deployable Systems. These trials are meant to study innovative designs of a new generation of economical, lightweight, and rapidly deployable sonar systems. The RDS-4 trial is scheduled for September/October 2002, and will take place in the approaches of Halifax Harbor and Emerald Basin (Scotian Shelf). This report characterizes the acoustic and oceanographic environment of both areas. The first site is adjacent to the coast at the entrance of Halifax Harbor. The very shallow-water site was chosen to maximize opportune target traffic near the RDS systems. The second site is located in water depths on the order of 100 m in Emerald Basin southeast of Halifax Harbor. This site will allow for a wide range of deployment depths for the experimental systems. It will also allow potential submarine targets to conduct submerged operations. Fishing activity is also more likely at this site.

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.
