Establishing Baselines for Fiji’s Coral Reefs

Coral reefs occupy less than one percent of the ocean floor, yet 25% of all marine life call coral reefs home. But, their homes are being threatened. The oceans have been dramatically changing and this change is often going unnoticed. With the recent climate report from the Intergovernmental Panel on Climate Change (IPCC) urging governments and individuals to take action now to reduce the effects of climate change, it has become even more critical for us to start monitoring and changing the way we affect aquatic environments.

Coral reefs occupy less than one percent of the ocean floor, yet 25% of all marine life call coral reefs home. But, their homes are being threatened. The oceans have been dramatically changing and this change is often going unnoticed. With the recent climate report from the Intergovernmental Panel on Climate Change (IPCC) urging governments and individuals to take action now to reduce the effects of climate change, it has become even more critical for us to start monitoring and changing the way we affect aquatic environments.

Over the past four years, Global Underwater Explorers’ (GUE) conservation initiative, Project Baseline, has been collaborating with scientific and government entities around the globe to provide data on critical environments using divers and submersibles. Last year, GUE sent a team of divers, scientists, and volunteers to Fiji to explore and establish baseline conditions for several of the world’s healthiest remaining coral reefs.

“It is our responsibility and certainly our mission as Project Baseline, to get out there and document these reefs in order to understand what is here and to present that, not only to scientists, but also to local people and to the world to encourage them to care more about what is here and to try harder to protect it,” Project Baseline Director Dr. Todd Kincaid said.

The mission in Fiji took place over fourteen days onboard the private motor yacht m/y Ad-Vantage, which was donated for use by the project along with its submersible Moby, to collect data on the health of deep and shallow Fijian coral reef ecosystems at ten different locations.  

Dr. Brian Walker and Dr. Ciro Rico photographed coral populations during 16 open circuit dives. Some of the images from the different sites they visited can be seen on Project Baseline’s database. 

The Diving

For the Fiji mission, Project Baseline partnered with Dr. Ciro Rico from the University of the South Pacific in Fiji, and Dr. Brian Walker and Dr. Charles Messing from Nova Southeastern University in Florida. Drs. Walker and Rico were able to complete 16 open circuit dives to conduct detailed documentation of specific coral colonies at depths between 12 and 20 meters.The GUE technical dive team, made up of Mel Jeavons, Jamie Obern, Martin McClellan, and Kincaid, conducted three plus hour-long dives where they collected fifty-five 50-meter long video transects at depths of 30, 20, and 10 meters.

Ad-Vantage’s submersible pilots also conducted 12 video transect dives. The dives were made at the same or nearly the same locations as the dive teams but between the depths of 50 and 362 meters. The primary mission of the submersible dives was to collect vertical video transects of benthic conditions across the steepest portions of the slopes. In addition, Dr. Messing was able to go on eight submersible dives during which he documented deep benthic life forms and collected 29 physical samples. The samples were later preserved and delivered to USP to be added to their South Pacific archives.

“One of the things we did find is that as we ascended from deep water of 300-400 meters, life got more abundant and diverse as we reached the top of the deep reef wall,” Dr. Messing said. “There were also some interesting parallels with the Bahamas where I have dived before. Because both of these environments are limestone, we saw some of the same basic geological structures, and organisms used some of the same adaptations as those on the opposite side of the world, which I found really interesting.”

The team of rebreather divers was responsible for taking video transects of both the benthic and the fish life at varying depths. The footage is then shared with scientists and students. The footage from this trip will help one student develop his thesis. Pictured here are GUE divers Mel Jeavons, Jamie Obern, and Martin McClellan.

Reaching Out to Villages

Project Baseline missions are not limited to just science or diving, but also include public outreach. The Fijians rely on the ocean to live. Their food and their economy depend on the health of the coral reefs that surround the islands and their livelihoods are threatened by a lack of understanding and adequate protections.

To combat this threat, Project Baseline reached out to Fijian villages that were near the dive locations in order to share what is happening beneath the waves with the people it matters to the most.

We met with village leaders and invited them aboard the m/y Ad-Vantage and for tours of the ship and the sub, as well as an overview of our mission and its relevance to our efforts to protect and sustain their ties to the sea. We also met with and described our mission to municipality leaders in Vunisea and representatives of Fiji’s Department of Fisheries and Wildlife.  Project Baseline hopes that by sharing what is happening underwater with the people of Fiji, they will take the first steps in managing how the reefs will be impacted in the future.

One of the most important elements to the mission in Fiji was to share what we were doing with the Fijian Villages near the sites we were diving. Here, Dr. Todd Kincaid is explaining our mission objectives to one of the chiefs.

Results

The good news? There is still a cause for hope.

“The reefs that we have monitored so far are in relatively good health compared to other sites of the world,” Dr. Rico said. “And in particular to see that the Astrolabe Reef is pretty much a pristine ecosystem. I think it’s a model of healthy coral ecosystems, and it is obvious that the remoteness of the place and the fact that it is far from human settlement is an important difference.”

Not all of the locations we were able to dive were as healthy as the Great Astrolabe Reef. Signs of distress and disease were present on the reefs that were closer to populated islands.

“In the areas that we have visited on this trip, we haven’t seen evidence of mass bleaching,” Dr. Walker said. “We have seen some disease. There were low levels of disease at most sites. At sites closer to human populations we saw an increase in dead coral and cyanobacteria blooms and other indicators that they are probably being impacted by their locations.”

The reason for the diseased and dead coral is still being examined. However, all indicators point toward stresses from local unsustainable land uses – pollution and overfishing – rather than global warming or climate change. If there is a silver lining, it is that these are impacts that can be quickly and effectively countered through public engagement and an investment in sustainable practices. The effects go beyond just the health of the coral. Jeavons and Obern were a part of a previous study collecting video transects on Fijian Coral reefs and they noticed some differences since the last time they visited the islands

“You can see the commercial fishing pressure on the reefs. I remember when we were here 20 years ago there were a lot more of the big predators. A lot more grouper, a lot more snapper and they’ve just gone,” Obern, a GUE instructor from New Zealand said. “If you haven’t collected the data and you can’t give something that’s measurable, definitive to prove to people that it is gone, then it is just in my memory. To come back here and get more baseline data so we can say, no this is what’s happening going forward, is really important.”

Onboard the m/y AdVantage, scientists from Nova Southeastern University in Florida, and the University of the South Pacific (USP) in Fiji were collecting specimen during the submersible and scuba dives. Here, Dr. Charles Messing from Nova and a masters student from USP preserve pieces of coral and sea fans to study after the mission was completed.

About Project Baseline

GUE’s Project Baseline initiative started in 2009, is at the forefront of data collection efforts by citizen scientist divers around the world. With over 100 projects in 38 countries, the initiative is more than just the Global Missions you may have read about. Our volunteer divers have collected over 2,700 images, 46,000 temperature readings, and almost 4,000 visibility measurements, all of which are visible on our public database.

Book Review: “We are the Ocean,” by Captain Paul Watson

An illustrated journey to teach kids about the importance of water. 

By Amanda White

When you read with children, they are connecting the words you say to the pictures on the page and to the things they see and do in their world.  That seems pretty obvious, but a lot of parents don’t make the connection that the stories you choose to read to your kids can have a great impact on your child’s outlook of the world and themselves. 

So, for us underwater lovers and environmentalists, books that cover these topics are key to teaching our children how important it is to protect and love the planet we call home and the creatures that live here. Storytelling is a powerful way to not only encourage your child’s imagination and further their education, but it is also a great way to shape the way they will go out and care for the planet and the beings on it.

Such books covering topics related to environmentalism and protecting the ocean are growing within the children’s book industry. One such book that was released this year is “We Are the Ocean” by Captain Paul Watson who founded the activist organization Sea Shepherd, whose mission is to protect and conserve the world’s oceans. 

In his book Captain Watson explores the connection between water and all living things. He takes a poetic stance toward describing how water sustains life and the continuous cycle through which it goes through all animals and plants. He explains this very simply for kids to understand the concept on the most basic level. 

With beautiful illustrations by Sarah Borg that depict the adventure of two children and their dog friends, your child will learn about the importance of water and our direct relationship with it. The book teaches kids that water is in the cells of all plants and animals, including their own bodies. It even explains that readers drink water that was “once within the body of dinosaurs”. The book does a great job of sharing the concept that the ocean is a part of all of us and even has a Sea Shepherd boat in the illustrations. The hope is to instill young readers with a love for the ocean and a passion to take care of it as they grow older.  It rings true of Captain Paul Watson’s most infamous quote, “If the oceans die, we die”.

“We are the Ocean” is great for kids who are just learning to read, as it is written for kids ages 3-5 years old who are in preschool or kindergarten. This book would be a great addition to your child’s reading list and would make an excellent holiday gift for the ocean-loving kids in your life. You can find We are the Ocean online and in stores at Barnes and Noble, on Amazon, and in the Paul Watson Shop.

A Bit About Captain Paul Watson

Named by Time magazine as one of the “Top 20 Environmental Heroes of the 20th Century,” Captain Paul Watson, has been fighting for our planet for over 60 years.  For years he worked on freighters and deep sea vessels and it was because of this, as well as his participation in a  demonstration at the U.S. and Canadian border, that he and several others created Greenpeace. Watson and the group were demonstrating against nuclear testing on Amchitka Island in the Aleutians. He continued his activism, and in 1977, he founded Sea Shepherd Conservation Society, whose mission is to be “a global movement to defend, protect and conserve life and diversity in the ocean.” Today it truly is a global movement with chapters in over 40 countries and is one of the few organizations that is actively protecting wildlife. Their current campaigns are, “Saving the Vaquita”, “Preventing IUU Fishing”, “Protecting Wild Salmon”, “Beaked Whale Research”, “Protecting Sea Turtles” and “Ocean Cleanup”
