Reef Night Dives Fluorescence Corals

The movie shows the reef during night dives using fluorescence with special HiTec LEDs. Living corals in contrast to dead ones show different intensive colors. The species specific colors are correlated to GFP (green fluorescent protein). For the detection of GFP in a jellyfish three scientists earned the nobel prize for chemistry in 2008. The fluorecent technique can be used for large scale analysis of the status of coral reefs worldwide which are under natural and anthopogenic threat.
