Map the Reef, Help It Grow.

Looking for a course you won't find anywhere else? 3D Mapping & Coral Gardening was created by Manta Dive and is only offered on Gili Trawangan. Over 2 days and 4 dives, you film the reef to build detailed 3D maps, plant and care for corals, and take part in real experiments that measure how well coral gardening helps reefs recover.
 
This is hands-on conservation: the footage you shoot and the corals you tend feed directly into ongoing research on the health of the Gili reefs.
 

Skills You Will Gain

  • Reef Research Methods: how scientific experiments are set up to test what really works for reef health.
  • 3D Mapping: understand how underwater 3D mapping works, then shoot the footage yourself.
  • Substrate ID & Coral Gardening: tell hard corals, soft corals, sponges, algae, rock and rubble apart, spot when a reef is out of balance and help damaged areas regrow.

What Is Included

  • Theory & 4 Training Dives: every lecture and dive on the course programme.
  • Complete Dive Gear: mask, fins, wetsuit, BCD, regulator, tank and weights for all your training dives.
  • 3D Mapping Equipment: cameras and everything needed to film the reef.
  • Coral Gardening Tools: gloves, tools, slates, transect lines and all other equipment for the practical sessions.
Not included: Marine Park Fee of Rp100,000 per person, paid in cash on arrival.
