Blackwater and Bonfire Diving in North Sulawesi

 

Dive into the Deep, Discover and be Amazed!

Have you heard of blackwater or bonfire diving? Do you know what they are? These are exciting dives which reveal some incredible critters in their larvae stages – many of which are not seen by the majority of divers.

It All Begins with Plankton
There are two types of plankton; zooplankton (which is animal based) and phytoplankton (which is plant based). These two forms of plankton drift with the ocean currents and are the source of all marine life. The word “Plankton” is derived from the Greek word “Planktos” which translates into English as “drifter” or “wanderer”. Did you know that in one teaspoon of sea water there are literally billions of life forms?

What is Blackwater and Bonfire Diving?
Blackwater diving takes place over deep water, away from the reef. From Murex Manado and Murex Bangka we usually head out from the resorts into the open ocean. Bright lights are suspended in the water column at various depths up to 25 meters. The lights attract plankton in the water column which in turn attracts intriguing and rarely seen larvae stage critters.

Bonfire diving takes place at shallower depths on the reef or sandy slope – at both resorts we have no shortage of suitable dive sites. Bonfire diving is also based around the use of bright lights to attract plankton and larvae stage and more mature critters.

Blackwater and Bonfire Underwater Photography Subjects
The most iconic blackwater and bonfire dive critters include crustacean and cephalopod larvae. Other common subjects include jelly fish and other critters which drift freely in the open ocean. Many of the larvae stage critters are not yet displaying any coloration and are often translucent as they are in the early stages of development. Both types of diving feature a lot of critter behavior spotting and imaging opportunities.

Best Times for Blackwater and Bonfire Diving
It’s possible to blackwater and bonfire dive at any time but the most abundant dives are around the new moon – up to 4 days before and 3 days after. Around the new moon there is little moon light so the bright dive lights become more active. When there is a full moon there is already light on the surface so the level of activity is dispersed and less centered around the dive lights.
