Gulf of Tomini

Gulf of Tomini covers the area of six million hectares. It is bounded by Minahasa Peninsula. On the eastern side, the gulf meets the open Molucca Sea.  Thus, the gulf is classified as semi-enclosed water. This condition brings several benefits to the gulf. First, is that the gulf has stable current that makes the objects safe and comfortable enough for diving. Second, pelagic marine life becomes very lively and varied.

The third benefit for being a large semi-enclosed water is that this gulf becomes the best habitat for plenty species of corals to live. World Ocean Conference and Coral Triangle Initiative Summit has agreed to note the Gulf of Tomini as the Heart of Coral Triangle. Overall, there are about 500 species of coral noted to live on this amazing gulf.

The depth is varied and can reach up to 4,000 meters deep with several walls of vertical drops. The walls are great spots for diving as you can find various species of sea animals and corals. Do not get surprised if you encounter some sharks, whales, trevallies, and even dolphins.

The formations of the walls are also fascinating as you may see some caverns, holes, and cracks. Most of them were formed due to massive natural erosion from the ancient reefs. You may also find some hill-like formation on the base of the gulf.
