Opens an interactive Shiny application for analysing underwater light environments. It has five guided tabs:

  • Depth Propagation – attenuate a built-in or uploaded irradiance spectrum through a Jerlov water type and download the per-depth lux and photon-flux table.

  • Species Perception – photoreceptor quantum catch for a chosen species under a selected bundled light-source condition at that source's stated reference depth.

  • Colour discrimination – Vorobyev-Osorio just-noticeable difference (JND) between two reflectances under the in-water light field.

  • Visibility – Secchi depth, photic depth, and horizontal visual-range scenario estimate.

  • Detection – explicitly unvalidated object-background contrast-threshold distance scenarios.

Requires the shiny package.
