[ 1 ] [ 2 ] The investigation was led by Captain Morris G. Jory. [ 3 ] The posthumous investigation was led by Lieutenant Commander Joseph R. Scullion.
The loudspeaker setup offers the advantage that stimuli can be precisely controlled to mimic natural stimuli or to test certain wave properties. Wave characteristics are measured optically. This is done by shining a laser (often helium-neon) at the water surface. Reflections and distortions of the laser's beam are picked up by a photodiode.

The use of sight probably varies with species and water conditions. The shark's field of vision can swap between monocular and stereoscopic at any time. [58] A micro-spectrophotometry study of 17 species of shark found 10 had only rod photoreceptors and no cone cells in their retinas giving them good night vision while making them colourblind.

[3] It is set in the scenic North Cascades, which is a sub-range of the Cascade Range. The peak is situated midway on the high ridge which connects Forbidden Peak with Boston Peak.
Usually the setup of a fluorescence assay involves a light source, which may emit many different wavelengths of light. In general, a single wavelength is required for proper analysis, so, in order to selectively filter the light, it is passed through an excitation monochromator, and then that chosen wavelength is passed through the sample cell.
