Resonances due to near-bottom soliton packets
Bibliographic record
Abstract
At the Acoustical Society of Americas Nashville meeting, 28 April–2 May 2003, we presented oceanographic modeling and acoustic modeling of the ONR winter 1997 Primer4 experiment conducted on the shelfbreak and continental slope south of Cape Cod in the Middle Atlantic Bight. Near-bottom solitary internal wave simulations in this region were generated using a forcing tidal velocity of 0.3 m/s to initiate the primitive equation Lamb model. The simulated internal waves were benchmarked against oceanographic data taken by Lynch. Similar to the acoustic mode coupling mechanism seen in the near-surface solitary wave packets, these near-bottom solitary internal waves also exhibited acoustic mode coupling—in this case the coupling transferred the acoustic energy from the trapped normal modes to the lossy continuous modes. This resulted in a loss in signal intensity, but no accompanying resonances were observed. As an update to that work we will show cases where the resonances are present, and are due to the conversion of the acoustic energy from the trapped normal modes to the lossy continuous modes.

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.
