Abstract
Remote sensing of coral reef environments may provide ecosystem managers with an effective monitoring tool, however, it is currently limited by some unexplained changes to the signal received by the sensor. Existing water column correction techniques attempt to account for signal modification by using Beer's law of logarithmic decay to account for attenuation of downwelling irradiance. Our objective for this study is to use downwelling irradiance values, collected in situ, to statistically evaluate Beer's law and suggest the appropriateness of applying a constant value of attenuation to satellite or airborne imagery. Findings suggest different bottom types and depths may modify attenuation coefficients differently. As a result, Beer's law of logarithmic decay is not appropriate for water column correction techniques for shallow water environments over bright surfaces.

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 it
