Fluorescence for Underwater Research: Principles, Tools, Techniques, Applications and Discoveries Charles H. Mazel NightSea LLC 20 New England Business Center, Andover MA 01810 Abstract Fluorescence is the phenomenon by which light is absorbed at one wavelength and re-emitted at another, longer wavelength. Many marine organisms contain fluorescent substances, and the right excitation light source can reveal surprising new colors and patterns. While there were sporadic early scientific investigations of instances of fluorescence in the marine environment, more focused research projects are of very recent vintage. Despite this, fluorescence is already proving to be a useful tool for a variety of marine science applications. This paper reviews the history of underwater fluorescence investigation, the principles behind it, the tools and techniques for using it, current and potential applications, and some of the interesting discoveries that have already been made simply as a result of going out and conducting pure exploration for fluorescence in the sea. Introduction It is often the case that if you look at things in a different way you see new and potentially interesting aspects of them, and fluorescence certainly gives you a new and different view of the underwater world (Figure 1). Using fluorescence as a tool for marine biology is an idea that has appeared and re-appeared over the last 70 years, but it has only recently begun to take root as a practical technique with specific applications. As such it is still a relatively unexplored phenomenon, and we make new discoveries almost every time we go beneath the surface in the dark. Most divers have already seen underwater fluorescence, even if they are not aware of it. If you see an intensely orange coral at a depth of 20m, it is fluorescing. The orange wavelengths of light have been removed from the downwelling solar radiation by the filtering effect of water, so the only way to be orange at depth is to fluoresce. Many corals have intense green coloration that arises from fluorescence. But many corals and other organisms that appear dull in daylight, or under a white light at night, at any depth will glow with remarkable colors and patterns when illuminated with the right light in the dark, while most organisms that are intensely colored in daylight do not fluoresce at all. You generally can't predict whether something will fluoresce from its 'normal' appearance, so you just need to get in the water and look. This presentation reviews the history of underwater fluorescence investigation, the principles behind it, the tools and techniques for using it, current and potential applications, and some of the interesting discoveries that have already been made simply as a result of going out and conducting pure exploration for fluorescence in the sea. 1
