What is Midnight Dive/Black Water Dive?
Midnight dive or Black Water Dive refers to diving conducted when daylight is no longer present, therefore Black Water Dive. It became popular in Hawaii first but has during the last years spread all over the world and is today a popular form of diving, especially for macro- and photo/video enthusiasts.
Like many living creatures, plankton is attracted by light. By putting artificial lights in the ocean we can attract huge groups of plankton and thereby also attract pelagic creatures (filter feeders) form the depths of the ocean. Black Water dive can be done in many different ways but the most common way is to either rig a drop off with lights to attract the small creatures of the ocean or attach lights under a boat that is either anchored or drifting. When midnight dive with our live aboard Ryoma I, we setup many lights on the edge of the drop off around 10 meters deep, to create a bright area just outside the edge of the drop off and attract the fishes living in the deep dark waters below and around the drop-off.

Compare to traditional night diving, this style of diving means less swimming around with a flashlight to look for fish and instead we can just wait around the “light area” for the fishes to come up. The kind of marine life you can experience during these dives is probably species you never encountered before or at least not in that stage of its life cycle. Juvenile fishes are very vulnerable and to have a chance to survive until adult age they need to either stay close to the surface or deep down in the water during daytime. But by night, attracted by light and food they come to these “lighted area” to feast on the plankton, larval fish and drifting jellyfish gathered. Many kinds of juvenile fishes can be spotted together with jellyfishes, squids and much more mysterious creatures.

Why Palau?
Palau is well known in the diving community for its extraordinary marine diversity and with all of Palau´s reefs and drop-offs; it becomes a perfect place to experience Black Water Dive and all of its beautiful creatures. The upwelling current around the drop-off´s makes a perfect environment to set up lights and attract a big number of different species. Especially the juvenile fishes are usually not strong swimmers, meaning an upwelling current is a big help for them to reach other depths.
