Modeling the Spatial Response of the Airfoil Shear Probe Using Different Sized Probes
Bibliographic record
Abstract
The airfoil shear probe is the only robust sensor currently available for measuring the rate of dissipation of kinetic energy in the ocean. The wavenumber (or spatial) resolution of the shear probe is determined by its physical dimensions, while the bandwidth of shear fluctuations is determined by the rate of dissipation. For most oceanic work, the conventional airfoil probe resolves the shear spectrum adequately. However, measurements taken in regions of larger dissipation rates, such as boundary layers, require a resolution beyond that of currently available shear probes. A newly designed probe, with dimensions approximately one-half of those of the conventional probe, was tested side by side with the conventional probe in a vigorously turbulent tidal channel. The relative response of the two types of probes indicates that both probes are characterized by a single-pole low-pass filter, with half-power wavenumbers of 49 and 88 cpm for the larger and smaller probes, respectively. After correction for this response, the spectra from both probes agree closely for the dissipation range 10−7 to 10−4 W kg−1. Variance estimates from corrected spectra only agree with the Nasmyth empirical spectrum over a limited range in dissipation rate.

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.
