These islands are part of the Rock Islands an archipelago that includes approximately 250 to 300 islands in the group. The Islands were in part formed from limestone of accent coral reefs and coral uprisings. The Rock Islands are a World Heritage Site since 2012.

The latest report from the Khaled bin Sultan Living Oceans Foundation finds Palau’s reefs had the highest coral cover observed on the Global Reef Expedition—the largest coral reef survey and mapping expedition in history.Scientists at the Khaled bin Sultan Living Oceans Foundation (KSLOF) have released their findings on the state of coral reefs in Palau.

Their research, based on extensive underwater surveys, found Palau’s reefs had the highest live coral cover of all the reefs studied on the Global Reef Expedition, a scientific research mission to assess the health and resiliency of coral reefs around the world.

Published today, the Global Reef Expedition: The Republic of Palau Final Report summarizes the Foundation’s research on the status of coral reefs and reef fish in this island nation and provides conservation recommendations that can help preserve these outstanding coral reefs for generations to come.

Over the course of five years, KSLOF’s Global Reef Expedition circumnavigated the globe collecting valuable baseline data on coral reefs to address the coral reef crisis. In 2015, the Global Reef Expedition came to Palau, where an international team of scientists and local experts spent nearly a month at sea surveying coral reefs in ten states across the country. Working together, they conducted over 1,800 standardized surveys of the benthic and fish communities on coral reefs in Palau.

They found Palau’s coral communities to be in excellent condition compared to other reefs in the region. The average live coral cover recorded in Palau was over 45% and reached 60 or 70% in some marine protected areas.

This coral cover is very high, even among the world’s best coral reefs. “Palau’s coral cover is truly exceptional,” said Alexandra Dempsey, the Director of Science Management at KSLOF and one of the report’s authors. “It indicates a robust benthic coral reef community with high coral cover and species diversity.”

These coral reefs have likely benefited from Palau’s efforts to conserve their natural marine heritage. Palau has a long history of marine conservation. Key is the traditional policy of “bul”—a moratorium on catching particular species or fishing on certain reefs to protect habitats that are critical to the community’s food security.

Conservation of the country’s reefs was further boosted in 2015 by the establishment of the Palau National Marine Sanctuary, which delivered one of the world’s largest protected areas of ocean.

“Unsurprisingly, this long- term commitment to marine conservation has delivered some of the most vibrant reefs the Foundation encountered on its Global Reef Expedition,” said Dr. Sam Purkis, KSLOF’s Chief Scientist as well as Professor and Chair of the Department of Marine Geosciences at the University of Miami’s Rosenstiel School of Marine and Atmospheric Science. “Given that Palau’s efforts are yielding tangible conservation results, the country might serve as a role model to other countries in the South Pacific and beyond.”

Despite a thriving coral community, Palau’s reefs had fewer and smaller fish than would be expected for a healthy coral reef ecosystem. Reef fish communities in Palau were similar to those surveyed in other nearby countries in the south and western Pacific. Many of the biggest fish appeared to be missing. Signs of overfishing were also observed on some of Palau’s nearshore reefs despite existing regulations, particularly on reefs near population centers.

“Fish are a critical component of a robust coral reef community. They’re important not only ecologically, but for the people who depend upon the reefs food or income,” said Renée Carlton, Marine Ecologist at KSLOF and lead author on the report.

“We saw some warning signs regarding reef fish communities, but are also hopeful that by expanding current fisheries management regulations and establishing more no-take no-entry areas, Palau’s reef fish communities could become some of the best in the world. The commitment Palauan’s have made to conserving their reefs is highly commendable and I hope they’re able to use the findings in this report to continue preserving their natural resources for future generations.”

The Global Reef Expedition mission to Palau gave scientists the chance to study some of the most beautiful and pristine coral reefs in the western Pacific Ocean. For the most part, the report released today shows what reefs can be when given the opportunity to thrive.

Although several years have passed since the expedition, data from this research mission will be critical for monitoring changes to the reefs over time and help managers identify priority sites for conservation action. The Living Oceans Foundation has shared copies of the report with government officials, conservation organizations, and marine managers so that these findings can aid in ongoing coral reef conservation and management efforts in Palau.

The Study of Palau Coral Reefs:

“Global Reef Expedition: The Republic of Palau Final Report” was published online on October 19, 2020. The study’s authors include Alexandra Dempsey and Renée Carlton from the Khaled bin Sultan Living Oceans Foundation, and Sam Purkis of the Khaled bin Sultan Living Oceans Foundation and the Rosenstiel School of Marine and Atmospheric Science at the University of Miami. Copies of the report are available to view and download on the foundation’s website at lof.org.

Is This The Best Dive Center Ever? W\@wakatobidiveresort

@sennacher 
#askmark Hi there, regarding DSMBs. I’m no expert whatsoever and normally I deploy it correctly. This weekend we dove on very strong current and I almost lose my breath while deploying it (mouth inflate) as it tangled a bit on my reg. It scared the sh&t out of me so. Is there any “little cylinder” kind of thing in order to keep my reg in my mouth to deploy it safer?  I haven’t tried to do it with my LPI… but asume it would tangle also.
Thanks

How Twinset Valves Work In Scuba Diving | Shutdown Drills And Isolator Tips Explained #scubadiving #askmark #twinset

Confused about how to use twinset valves or perform a proper valve shutdown drill? You’re not alone.

In this AskMark episode, Mark explains how valves work on twin cylinders, including how to safely open and close them, how isolator valves function, and why valve drills (also known as shutdown drills or V-Drills) are critical for diagnosing leaks during technical and recreational dives. Please visit our website for more Scuba news, underwater photography, hints & advice, and travel reports: https://divernet.com/ 

Mark also shares tips on muscle memory for reaching your left and right posts, isolator-first vs isolator-last logic, and how to prevent over-tightening or unsafe valve positioning. This guide is perfect for divers transitioning to twinsets, sidemount divers curious about manifold setups, or anyone wanting to improve their gas management skills. 

Let us know in the comments how your instructor taught valve drills and don’t forget to leave your questions using #AskMark to get featured in a future video.

#askmark hi Mark. Could you do a video on how to deal with the valves and manifold on twin cylinders. It’s confusing to remember which way to open the valves and it’s easy to get wrong particularly in emergencies. Thanks
