October 16, 2009 – Biorock Monitoring
Koh Tao’s Biorock, our major project for 2008 continues to thrive at its home over by Koh Nangyuan on the island’s northwest. It isn’t dived as regularly as we would like so Eco Koh Tao organised another introductory dive for divemaster trainees and instructors who had yet to visit this ground breaking project. Due to a weak buoy line we are limited in our visits to days when the weather is exceptionally calm and the boat pressure on the insufficient anchor is minimal. Thankfully we had a perfect day for this visit and 11 of us took the opportunity to explore Hin Fai.		Monitoring continues on the Biorock site where estimates are made of random selections to guage coral coverage and growth at the site.
As well as being an introduction to the dive location it was also an opportunity for us to add valuable biological diversity to the site by transferring coral fragments found nearby on the sea floor. As a site its scientific importance is of great value being one of the largest Biorock sites in the region. Research is important to determine whether the techniques and its technology deliver the projected results. IDCS Nathan Cook and Advanced Open Water diver Jacqui Cook collected growth data using a 1 square metre template to estimate the amount of coral coverage on the site. This is being done on a regular basis and will quantify the change of coral coverage as time progresses.

		Thank you to everyone who took time out to visit Hin Fai, some for the first time. All the divers enjoyed the dive immensely and will hopefully have a chance to visit it again as it progresses.
