Αποστολή Andi στη Twilight Zone 2004

In May 2004 a team of ANDI’s top (American Nitrox Divers International, Ltd.) divers traveled to Indonesia to explore the depths between 125 and 150 meters on the slope of Manado Tua Island (North Sulawesi).

The team was hosted by Murex Dive Resort & Liveaboard who provided accommodations, boats and support staff for the expedition. In addition, Murex offered the best-equipped gas blending station in the area which is a necessary part of an expedition such as this

The expedition was led by Bart De Gols, Director of ANDI Benelux and completed 14 team dives to depths of 100 - 150 metres using Closed Circuit Rebreather systems and housed underwater video cameras. This team included one of the pioneers of mixed gas technical diving, Ed Betts, Founder and Executive Director of ANDI International.

These dives took place on the fringing walls on the south side of Manado Tua Island. This is where several local fishermen have caught Coelacanth fish (Latimeria menadoensis).

Dr. Mark Erdmann, the project’s marine biology advisor had previously conducted one survey of the site from a manned submersible and believes that this twilight zone habitat is very suitable for coelacanths.

The ANDI team explored a large range of sites within Bunaken Marine National Park and recorded extensive video footage of the most interesting and unusual fishes and invertebrates encountered. The ANDIteam also mapped those areas of the twilight zone in BMNP that are most amenable to further exploration and development as deep technical dive sites.

These dives where the first dives ever to explore the twilight region below 75 metres in Bunaken Marine National Park. Several divers have dived below 75 metres breathing air and upon resurfacing, remembered little or nothing of what they saw. Also Ed Baktis, Deep Support Diver on this expedition made the first rebreather dive in the National Park. The ANDI team used their own proprietary software to plan, calculate and log these dives in the 500 fsw range. This cutting-edge software is now commercially available under the trade name ANDI-GAP DivePlanner. This impressive dive planning tool is of benefit to recreational as well as technical divers. A trial version of this tool is available at ...
