One of the most readily observable, and avoidable, damages to coral reefs is due to the dropping of anchors to park boats. Dropping an anchor instead of using mooring lines can destroy hundreds of years of coral growth in only a few moments, and leave a pile of unconsolidated rubble in its wake which can take decades or centuries to recover. Mooring lines are permanent lines attached to a solid base that boats can pick-up and attach to, rather than dropping anchors on or near the reef.
On Koh Tao, we have mooring lines at every dive site around the island, which not only allow boats to park but also improves the safety of divers ascending and descending. In all, there are over 130 mooring lines around the island as of late 2014. But this was not always the case. In 1998, only 3 of the island’s then 19 dive sites had mooring lines, and boats dropping anchors on the reef was identified by survey respondents as the most “prominent and visible impact” to Koh Tao’s reefs (Flumerfelt, 1999). Furthermore, many instructors on the island at the time told numerous stories of being almost hit by falling anchors while teaching courses to new students. The major problem, they said, with installing mooring lines was the cost, the lack of involvement by the island’s then 18 dive schools, and a lack of understanding about the maintenance involved.
In 2014, Shark Guardian managed to collect over 4,600 entries into the eShark Database, including sightings of 1,480 sharks from 10 different species. The sightings are submitted by concerned divers around the country, and around the world, in order to evaluate and track population levels for conservation efforts. The data collected is shared with national policy makers such as the Thai Department of Fisheries, as well as international organizations such as the IUCN.
This year, the group is ramping up the project yet again looking to get even more reports on sharks, turtles, marine mammals, and other important marine organisms or problems. From November 2014 – April 2015 they will try to get as many submissions as possible, and need your help to do so.
All divers can contribute to this database, even if you have never seen a shark. In fact, they need to know about the dives you have done and not seen sharks as much as they need the sightings information. Submitting data is easy, and takes only a few minutes, you can submit a couple of dives, or your whole log-book.
One of the most miraculous and important events in any organism’s life is reproduction. Every species does it differently, each evolving their own strategies to fit the physical and biological conditions specific to them. Normally, we are overjoyed to observe this rare event on the coral reef, such as with our yearly coral spawning and larvae culturing project. Or we spend large amounts of time ensuring the act was successful by caring for juvenile sea turtles and giant clams. However there are a few organisms on the reef which we would rather not see reproducing (other than the divers).
On September 12th, 2014 we observed the mass spawning event of several Crown of Thorns Starfish (COTs). These starfish are a major problem around our island, and have reached outbreak levels in some sites over the last 5 years. They are a corallivore, which can consume about 148-238 cm2 of our living coral from the reef each day. In many parts of the world, such as the Great Barrier Reef, they have been conclusively found to be a leading threat to reef health, and they have been trying to control them since the 1970’s. We also remove many of the starfish here around our island as often as we can, collecting 138 individuals from 9 sites in 2014.
2015 is a big year for New Heaven Dive School, as it marks the 20th year of providing great diving and wonderful memories here on Koh Tao. And to mark the occasion we would like to see many of our old family members, friends, staff, and customers come back and help us celebrate. So we are announcing it early, in hopes that people will have time to plan their trips. We will hold several parties and events throughout the year, which you can see on the schedule at the bottom of this article. But first, let’s have a look back at some of the most memorable events and people that have enriched our lives and ingrained themselves in our hearts to make New Heaven into what it is today.
New Heaven Dive was originally started in June 1995 by Kampanat NaSongkhla, or P’Kong, when he started diving from the beach in Chalok Bay with just 2 sets of dive equipment, 4 tanks, and a small longtail boat. With these humble beginnings, P’Kong looked to introduce visitors to the beauty of Koh Tao’s underwater world, and treated every customer as a dear friend, which they inevitably all became.
