Working first with Charles Mazel's nightsea equipment I started in 2007 in the construction of the first HiTec/High Power Underwater-fluorescence torches. I used the first HighPower blue LEDs, which were introduced by OSRAM Opto Semiconductors. Since this time I published many articles about the theory, which can be found as Links on my homepage > https://www.uni-due.de/zoophysiologie/
There you will also find Links to many of my YouTube movies. Besides nice photos during nightdives are scientific condiderations. In addition to Reef Check studies during the day we can monitor big reef areas by large scale scanning with our HighPoer torches, which allow an illumination of corals up till 30 meters. In this way one can check the state of the reef. Healthy corals send fluorescent light (species specific rainbow colors, dead or partial dead corals show a dark blue or even black color. An important point is the possibility to identify tiny recruits (around 1 -10 mm) in larger distance, which is not possible during daylight reedf check. These studies are important in the context of the worldwide threat of corals and their role as an important fish and evertebrate biotop and coat protection. A movie about coral deaseas con be found here >Coral Project Dahab 2012.mov - YouTube and here > CoralDiseasesHiTecFluorescence.mov - YouTube
The beaty of corals under fluorescence can be seen here: Fluorescence during Night Dives - To Be Or Not To Be - YouTube I have also tested the Light&Motion Sola.Nightsea in Marsa Shagra (South Egypt) in September 2013.
I think after 35 years with (microscope) fluorescence and electron microscopy in the laboratory the step to marine fluorescence was not to large.
As molecular biologist (embryologist) I worked on gene regulation during early embryonic development. By the way the embryoic development of all organisms is one of the most critical period also and especially for marine organisms. For our US readers and friends I should mention that I stayed 3 times for up to 7 month each (sabbaticals) in Oak Ridge National Laboratory, Tennesse (operated by the Atomic Energy Commission), at the NIH (Bethesda) and UCLA, LA.
Meanwhile we offer special filters (customer oriented) for underwater strobes, which are prepared for differnt strobes by 3D-printing > iGoScuba The theory behind it can be seen here:http://www.uni-due.de/zoophysiologie/ab.guests/PhosphorLowPDF For further informations you can reach me under my email adress horst.grunz et uni-due.de
I am looking forward to get important informations in this forum Best regards Horst
