Fire Walking

Written by

As the sun begins to set and the lagoonal waters are calm, I begin to smell the strong aroma of burning coconut husks and leaves as we approach the beach near the village Rukua on Beqa Island. The Pacific Blue Foundation (PBF) team and I are attending a fire walking ceremony, an important cultural and spiritual exercise that has its roots strongly tied in with the Beqa Island community.

Fire walking is a traditional ritual that has been practiced in various cultures around the world for centuries. One of the most well-known places where this ritual is still performed is in the Beqa Lagoon in Fiji. This ancient tradition is not only a testament to the Fijian culture but also a spectacular event that draws tourists from all over the world…

Measuring the size of a Tsunami

Written by

How big was the size of the tsunami that hit Tonga last year? A new study led by scientists at the University of Miami and the Khaled bin Sultan Living Oceans Foundation measured the size of the Tongan tsunami and found that it was similar in size to the one caused by the eruption of Krakatoa in 1883.

The 2022 eruption of a submarine volcano in Tonga was more powerful than the largest U.S. nuclear explosion, according to a new study led by scientists at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science and the Khaled bin Sultan Living Oceans Foundation.  

The 15-megaton volcanic explosion from Hunga Tonga-Hunga Ha’apai, one of the largest natural explosions in more than a century, generated a mega-tsunami with waves up to 45-meters high (148 feet) along the coast of Tonga’s Tofua Island and waves up to 17 meters (56 feet) on Tongatapu, the country’s most populated island.

In a new analysis in Science Advances, researchers used a combination of before-and-after satellite imagery, drone mapping, field observations collected by scientists at The University of Auckland, and high-resolution bathymetric maps from the Khaled bin Sultan Living Oceans Foundation’s Global Reef Expedition, to produce a tsunami simulation of the Tongan Archipelago. The results showed how the complex shallow bathymetry in the region acted as a low-velocity wave trap, capturing a more than hour-long tsunami with waves up to 85 meters (279 feet) high one minute after the initial explosion.

Science Without Borders®: Conserving the Tropics

Written by

The Science Without Borders®: Conserving the Tropics project was developed by the Khaled bin Sultan Living Oceans Foundation to help address the United Nations Ocean Decade Challenge to “understand the effects of multiple stressors on ocean ecosystems, and develop solutions to monitor, protect, manage and restore ecosystems and their biodiversity under changing environmental, social and climate conditions.”

Our project focuses primarily on conserving tropical marine ecosystems, including coral reefs, seagrass meadows, and mangrove forests, as well as incorporating measurable actions that communities can use to reach their conservation goals.

The Science Without Borders®: Conserving the Tropics project uses a co-design approach to help coastal communities improve ocean literacy and develop science-based solutions to conserve their tropical marine ecosystems…

Measuring reef health from space

Written by

With compelling evidence that we have lost half of the world’s tropical coral reefs over the last few decades, there is an urgent need to understand their overall health. Without this basic information to use as a baseline, it is near impossible to mount a response to the so-called global reef crisis. The most straightforward method we have for monitoring reefs is conducting SCUBA diver surveys. However, this type of field work is logistically and financially challenging to execute on large scales, so developing a new method to monitor reefs remotely is key.

In attempt to find a solution, Anna Bakker combines the fields of remote sensing, computer science, and ecology to measure reef health from space. Recently, Anna published a paper in Coral Reefs, which utilized the Living Oceans Foundation’s Global Reef Expedition field dataset to build a model that can predict coral cover and other metrics of coral reef health using open-source satellite data.
