Dive in to the heart of the Coral Triangle in Asia, home of the richest coral reefs on Earth
Thursday, June 4, 2015
Editors note: This post is the first in a series of guest entries by members of the
XL Catlin Seaview Survey
team, a group dedicated to recording and revealing the world’s coral reefs in high-resolution, 360-degree panoramic imagery. These posts will take you behind the scenes of the project and introduce you to the people taking these images.
Asia Pacific is home to some of the world’s top marine biodiversity hotspots. To celebrate World Oceans Day on June 8, we’ve worked with Google to
our largest ever collection of underwater imagery on Google Maps, featuring 360-degree virtual dives from
20 reefs across the region
, including the Philippines, Indonesia, the Solomon Islands, the Cook Islands, Australia and American Samoa.
Here’s a look at the virtual dive locations captured by the XL Catlin Seaview Survey team
Come take a closer look at how we carry out these underwater surveys by going behind-the-scenes on our dive at Indonesia’s Bunaken National Park, the heart of the Coral Triangle. Often called the “underwater Amazon,” the Coral Triangle is a 5.7 million square kilometer area that spans from the Philippines in the north, down to Indonesia and as far as the Solomon Islands in the east. This giant triangle is also home to 76% of known coral species and over 3,000 species of fish.

Every dive begins with getting our divers rigged up and the 60kg camera off our research boat Makarena and into the water. The SVII is a revolutionary camera system that creates high-resolution 360-degree images of the underwater environment using technology similar to Google Street View. By attaching SVII to an underwater scooter, we can cover distances of up to two kilometers in a single dive, taking about 3,000 images each time.
We’ve also added instruments to this camera set-up, including a depth transponder (altimeter) so that we can read the altitude of the camera from the sea floor, which allows us to gather standardized scientific information at a volume and scale which was previously unattainable to the marine science community.

We’ve seen large schools with hundreds of reef fish such as
(Chaedotontidae spp) or
red toothed triggerfish
(Odonus niger) cascade down the healthy reef slope. On this particular day, we were lucky enough to be greeted by a dolphin and a free swimming banded sea snake cruising along of one Bunaken Islands’ epic undersea walls.

While we could easily spend all day amongst the depths and colors of the Coral Triangle’s reefs, we try to complete our expeditions as early as possible to get started on downloading and processing the images. We’ll tell you more about the data we gather from these 360-degree photos in upcoming posts, but for now, we hope this new underwater imagery available on the
XL Catlin Global Reef Record
will give anyone with an Internet connection the ability to immerse themselves in stunning coral reefs like never before.
