One experience that you must have before you die is to swim with the florecerence. There are many things in nature that bring you closer to the magic that exists in biology but this phenomenom is at the top of the list. Swimming at night is an exilerateing activity, the ocean water seems like pool of inky darkness and the fact that you cannot see anything inside reminds one of how little control we have in this element if something was to come apon us. However, with biolumence, suddenly your movement makes the water come alive with lights. You step into the water and your foot becomes illuminated as you slide it along the sand, as you enter the water and begin to swim, you test this experience, twisting your hand below the surface watching the streams of light come of the back of your fingers. It is like you some sort of supernatural creature made from light who is constantly exfoiliting. It will make the temptetation of those midnight swims even more irresistable from that point forward.
Biolumence is the indication of a type of zooplankton is present in the water, which exists depending on the season, the currents, your location and the time at night. It´s a kind of plankton that will makes a nightly migration up the water column at the beggining of the night to reach its feeding territory at the surface, preying on different zooplankton and phytoplankton throughout the night before returning to the bottom as the morning approuches. You can see this too, as the reaction of light in the water will seem much stronger as the night goes on representing the concentration of the plankton. These type of zoolplankton have a short lifespand, so when they have food available their population quickly expands and quickly drops when they lack it. Since their food comes indirectly or directly from the amount of phytoplankton, the bioloumence observed in the water increases accordingly to when the conditions are right for the phytoplankton. The amount of sunlight and nutrients in the water control the phytoplankton populations so when conditions are correct for this you will accordingly see the biolumence increase aswell.
One of the nice things about sailing is it brings those scientific biology and oceanography classes into context. It gives you appreciation for these things you may of learned, they are not just facts that were memerized and found vaugely intresting, you now have a memory with an attached emotion of awe and beauty to give the a deeper significance to the knowledge.
