'Tis the High Season

We’re welcoming divers at New Heaven as the low season comes to an end. The sun is out and our sandy shores invite travelers from all around the world who are looking for a dose of tropical this winter.

In order to explore the hidden depths of the sea, we must become acutely aware of a process most of us don’t spare much thought to: our breathing. With my love of the ocean and Yoga it was a no-brainer for me to create a new course in Freediving and Yoga at New Heaven Dive School. Bringing two of my passions together and sharing them with other like-minded individuals has been a great success this past year.

Will Sea Turtles Survive the Anthropocene?

The modern day sea turtle has existed for around 80 million years, and they can be found in all ocean waters except the polar regions. There are now only 7 living species left in the world, so it is important to protect those that remain.

Meanwhile in the Maldives…

Recently, NHRCP instructors Kait Harris and Pau Urgell traveled to the Maldives to work alongside the Island Livelihood Institute, educating local island communities on coral reef ecology and artificial reefs as a tool for restoration. During our stay, we learned a great deal about the restoration efforts happening on many of the islands, and were able to pass on some of our knowledge too.

Once a year, during a period of about 15 minutes, many hard coral colonies of the same species will spawn synchronously in the same area. Corals cannot move, that’s why reproductive success depends on the accuracy in spawning time of all the colonies.

Recently, the mass coral bleaching event occurring on Australia’s Great Barrier Reef (GBR) has had extensive media coverage, bringing to light the severe consequences of the changing climate. But what is coral bleaching? And why is this year set to be particularly bad?

Although the climate is slowly warming globally according to vast scientific consensus, there are patterns of weather which influence particular areas of the planet, causing more severe weather events at certain periods of time. El Niño is a complex interaction between ocean and atmospheric temperatures which result in certain patterns of climate which prevail for 9-12 months at a time, occurring every 2-7 years.

A Not So Selfish Gene

One of the philosophies that is central to our work here at the NHRCP, is the preservation of the genetic diversity of our coral reefs.  Koh Tao’s reefs are beautiful and diverse ecosystems. containing a wide variety of different coral species and growth forms. The emphasis that we place on the understanding of coral taxonomy helps our team of conservationists gain an appreciation for the genera of coral that are less abundant on our reefs, encouraging the protection of these marginalized species.

Within the realms of biology lies an underlying skeleton that allows the very heart of the science to thrive, this being the concept of classification. The organisation and categorisation of different organisms can be based on type, size, and any number of variables and characteristics, each with its own crucial importance to research to the most detailed level, and to the largest biological questions of all. This skeleton is comprised of many parts, and at its very backbone, lies the concept of taxonomy, used as the most common form of classification. Taxonomy is the classification system by which organisms are divided into phyla, families, species, etc, and rely strongly on the variation in the internal anatomy of organisms and in modern analysis, differences in the genetic makeup between organisms, i.e, DNA. You can learn more about a taxonomic approach to classification in our introduction to key invertebrate species of Koh Tao and the Gulf, in our learning resources section here.

Giant clams, a sheltered reputation

Giant clams, Tridacna Sp., are not widely known by the every-day tourists. Three different species occur at Koh Tao; Tridacna maxima, Tridacna squamosa and Tridacna crocea. Although giant clams are not widely known, they can easily compete with the rest of the coral reef in a beauty competition due to their stunning camouflaging coloration. Moreover giant clams live up to their name and can reach impressive sizes, the largest species in this genus reaching up to 1.4 meters! At Koh Tao however the largest individuals grow up to a more conventional 40 cm.

Giant Clams get hold of food in two different ways. The first source of food for giant clams is zooplankton, which are obtained through filter-feeding, this is the main food source for giant clams in their early stages of life. Giant clams also have a symbiotic relationship with a unicellular algae (called zooxanthallae), which live in the tissues of the clams. These algae share some of the sugars and carbohydrates they produce, through photosynthesis, with the clam. Not only does the zooxanthallae provide about 90% of the clams daily energy budget, they are also responsible for the clams unique and ornate coloration.
