BIOROCK ELECTRIC CORAL REEF RESTORATION COMES BACK HOME TO JAMAICA AFTER 25 YEARS
The first new Biorock electrical coral reef restoration project in Jamaica for 25 years has been started.
The small project is located in front of Westender Inn, at the extreme end of the West End of Negril, facebook.com/westenderinn
Electric reef restoration technology was invented and developed 30 years ago in Jamaica by late architecture Professor Wolf Hilbertz and Dr. Tom Goreau at the Discovery Bay Marine Laboratory (T. J. Goreau & W. Hilbertz, 2012, Reef restoration using seawater electrolysis in Jamaica, in T. J. Goreau & R. K. Trench (Editors), Innovative Technologies for Marine Ecosystem Restoration, CRC Press).
It is a few kilometers from the last Jamaican Biorock project, in Little Bay. Local fishermen were amazed to see corals grow right over the solar panel powered Biorock reef.
Made from layers of conch shells, it was crowded with young lobsters and fish until the Biorock reef, the solar panel, and nearby houses were demolished by Hurricane Ivan on September 11-12 2004. Local fishers are eager to see more Biorock!
The area offshore from the project site had been a vast forest of elkhorn coral that reached the surface, which was demolished by Hurricanes Allen, Gilbert, and Ivan. There has been little or no sign of reef recovery along most of the coastline, except in a few small areas.
We have found elkhorn colonies nearby and are rescuing loose naturally broken coral fragments that are still alive but that would otherwise die, and propagating them on the Biorock reef.
There are so few remaining living naturally broken fragments now left in the area that we are starting with only around a dozen small naturally broken coral fragments, mostly Acropora palmata, Porites astreoides, Porites divaricata, Diploria clivosa, Diploria strigosa, and Agaricia agaricites. Two of these were found completely bleached where they had been washed into crevices.
But there are young corals of half a dozen species all over on the rocks underneath the Biorock structure, and these will grow up through the Biorock reef, while new corals will settle all around.
The result is that we will grow the reef upwards by about a meter, protecting the rocky shore from erosion, and eventually allowing sand to build up. The entire seafloor of the area is now eroding severely because it is densely covered with rock-boring sea urchins, constantly chewing holes right into the dead reef rock. We will turn a collapsing reef back into an actively growing one.
The return of life-saving Biorock electric reef restoration technology back home to the island of its birth can restore the lost corals, fishes, and vanishing beaches all around Jamaica if done on a large scale. Twenty-five years of involuntary exile from Jamaica were forced on us by lack of funding and support from both Jamaican and foreign institutions.
Since then we did around 400 Biorock projects in around 40 countries all around the world, keeping reefs alive when they would die from high temperatures and pollution, growing corals back rapidly in places where there has been no recovery, and even growing back severely eroded beaches in just months.
The Global Coral Reef Alliance thanks the Westender Inn, Negril for their support for the project, in particular Dan Brewer, Keith Duhaney, Steve Drotos, the entire Westender staff, Booty, Beenie, Ken, Ceylon Clayton, and the people of Orange Hill and Little Bay, Westmoreland, Jamaica.
Let’s make Jamaica’s coral reefs, beaches, and fisheries beautiful again: bring Biorock back home where it was born!

CORAL ARKS, CLIMATE STRATEGY:
SAVING CORAL REEFS IN THE SHORT AND LONG TERM
May 7 2017. The Global Coral Reef Alliance / Soil Carbon Alliance urgently seeks funding during 2017 to support leadership in Geotherapy: global ecosystem regenerative development to reverse climate change, and for the Biorock Electric Reef Coral Ark Program with Indigenous Peoples (below).
CORAL REEF ARKS
Coral reefs are the most sensitive ecosystem to global warming and will be the first to become functionally extinct due to excess atmospheric CO2 from fossil fuel combustion, imminently threatening the major marine biodiversity, fisheries, tourism, and shoreline resources of over 100 countries. The threat was fully understood by 1990, but was deliberately ignored for nearly 30 years by governments unwilling to solve the global climate change problem. As the result the current United Nations Framework Convention on Climate Change (UNFCCC) is a death sentence for coral reefs. Restoration of lost reefs is a life and death matter for the Small Island Developing States, and especially the atoll nations.
Massive coral mortality from heat shock took place across the globe in 2015 and 2016, record hot years, at precisely the temperatures forecast nearly 30 years ago by the Goreau-Hayes satellite sea surface temperature HotSpot method. 2017 will probably be even hotter, and many of the few Great Barrier Reef corals that survived the severe 2016 bleaching have bleached and died unusually early in 2017. Many new more regions will bleach this year as the equatorial and northern regions warm up. Since hotter years will certainly follow, we now have only a few years left to protect the last of the most critically threatened natural resource of the ocean.
Even if all fossil fuel use stops today, we will still face millions of years of high temperature, sea level, and CO2, continuing long after IPCC’s model projection time horizons of 50 or 100 years, condemning future generations to extinction of coral reefs and flooding of low lying coasts where billions of people live, unless CO2 is urgently reduced to preindustrial levels.
Biorock Coral Arks are the only way known to save corals from high temperature stress during the interim period until regenerative development strategies can reverse CO2 increase. During 2016 almost all the corals on Biorock Coral Arks in Indonesia survived the bleaching mortality of more than 95% of corals on nearby reefs, and they grew back a severely eroded beach naturally in just months. Indonesian fishing villages with Biorock reef projects have not only restored their fisheries, they have been transformed from the poorest villages on their island to some of the most prosperous, because so many tourists come from all over the world to swim over their spectacular Biorock corals and fish.
An immediate crash program is needed NOW to restore our damaged reefs using methods that 1) greatly increase coral growth rates, and 2) greatly increase coral survival from high temperature stress, and 3) work directly with coral reef communities. Biorock technology is the only method that does so, and can be powered on any scale by developing our vast but untapped clean and sustainable wave, wind, solar, and ocean current energy. Biorock methods greatly increase coral settlement, increase coral growth rates 2-6 times, prevent coral death after bleaching from heat shock, speed up coral recovery, and result in much higher survival, up to 50 times higher (5,000%) in the worst cases.
All marine organisms and ecosystems, not only corals, benefit from Biorock electric fields because they directly stimulate natural biochemical energy production. Biorock reefs greatly increase fish populations, create new sustainable mariculture opportunities, and build growing, self-repairing reefs of any size or shape that turn severely eroding low island beaches into growing ones naturally in just months, allowing them to grow despite global sea level rise. All other methods of coral reef restoration and shore protection will eventually fail catastrophically under global warming and global sea level rise.
In order to prevent catastrophic loss of fisheries, shore protection, tourism, and biodiversity in the coming years a massive program of coral reef restoration is needed in all the coral reef countries, and especially the Small Island Developing States (SIDS). Biorock Coral Arks are our last hope to maintain coral reef ecosystem services until global warming is reversed. There is no time to waste: failure means condemning around a billion people to become climate refugees.This should be under the direct control of the countries affected, using the state of the art Biorock methods, which have been developed in the SIDS, without any help at all from the rich countries or funding agencies. This is a long-term task, and only those really committed to
This should be under the direct control of the countries affected, using the state of the art Biorock methods, which have been developed in the SIDS, without any help at all from the rich countries or funding agencies. This is a long-term task, and only those really committed to long-term restoration of their immediate environment can do so. Only local people are seriously dedicated to restoring their own fisheries, shorelines, and natural resources over the generations that will be needed until global warming can be brought under control. To be truly effective, all funding should be put directly into community- based environmental management initiatives supporting local efforts to restore and manage the resources they have lost, not to foreign or even national institutions, who will waste the money on bureaucracies, foreign consultants, and big international NGOs (BINGOs).
They should specifically NOT be under the control of those programs funded and controlled by the rich countries, which have spent 40 years systematically denying the massive declines of reefs that were already long known in the SIDS, denying their clearly proven linkages to global warming, and actively preventing any effective action to restore coral reefs with fiction about “resilience”. These groups are now attempting to control all reef funding, and if they succeed they will waste all the money by repeating their past failures.
GCRA Community-managed Coral Ark projects will be designed and built working directly with indigenous fishing communities who have already shown they want to act to restore their marine resources, and whose trust we have won through years, decades, or generations working with them on their coral reefs. These sites will be used to train other community-based environmental management groups who want to restore their coral reefs, fisheries, and beaches in their regions. Our first priorities are:
Jamaica is where coral reef diving research first began and where the decline of coral reefs, and all their causes, were first documented and understood. Jamaica is also where Biorock electric coral reef restoration was invented by GCRA researchers Wolf Hilbertz and TG 30 years ago, but unfortunately there have been no Biorock projects in Jamaica for 25 years. We have worked closely with Jamaican fishermen documenting changes on the reefs for 65 year., TG, a native speaker of Jamaican patois, wrote the integrated whole watershed and coastal zone management plans for both ends of Jamaica. We will focus on coral reef and fisheries restoration in Westmoreland, where the fishermen still remember the amazing coral growth and fish and lobster populations attracted to solar powered Biorock reefs we built with them 25 years ago. The former reef is now a barren wasteland, and the locals want to restore their collapsed reefs and fisheries.
The Guna Indians of Panama are lobster divers who live on 50 low islands, a quarter of which they are now abandoning due to erosion caused by global sea level rise. They are already global warming refugees! Our work there focuses on restoring coral reef growth to restore the lobster and fish populations, and growing Biorock shore protection reefs to save their islands from erosion and grow new islands. The Guna are a remarkable traditional culture that never lost their independence, have preserved all their cultural and political institutions, yet greatly value education and modern knowledge. Although TG is of Ngobe Indian descent (the largest and poorest indigenous community in Panama), his family have worked closely with the Gunas for generations, and he has complete authorization by the Guna Government to do environmental restoration projects there, something no other outsider has. The local will is there, but funding is nonexistent for independent Indigenous communities.
The Comca’ac (Seri) Indians of the Sea of Cortes are the smallest and most remarkable Indigenous culture of Mexico. They survived for hundreds of years in barren desert islands by diving for seafood, in particular, several unusual endemic species now on the verge of extinction. TG dived with them to understand the growth conditions of their unique biological resources and is working with them to develop their remarkable tidal energy resources to produce electricity, fresh water, Biorock building materials that consume CO2 from the atmosphere, and much more productive Biorock mariculture of their threatened native species.
Indonesia has the world’s largest, richest, and most biodiverse coral reefs, yet around 95% have been badly damaged. Our Indonesian team has built around 300 Biorock coral reef restoration projects in many islands of Indonesia, including Bali, Lombok, Flores, Sulawesi, Sumbawa, Java, and Ambon. These have created prosperous ecotourism communities, restored fisheries, preserved coral reefs from dying from global warming, grown back severely eroded beaches in months, and won many international environmental awards, including the United Nations Equator Award for Community-Based Development and the Special UN Development Programme Special Award for Oceans and Coastal Management. The Biorock Indonesia team is developing plans for large Biorock mangrove restoration projects in areas destroyed for shrimp farms that will become Orang Utan habitat in Kalimantan (Borneo) as well as major mangrove peat carbon sinks, restoring areas damaged by mining in Sulawesi and Halmahera, and restoring eroded beaches in Raja Ampat, West Papua. We have trained hundreds of Indonesian students in the new restoration methods, but there is no funding for them to help the fishing communities all across this nation of 17,000 islands and 250 million people that are asking for training to also re-grow their reefs, fisheries, and shorelines as the first communities we trained have done.
In Vanuatu, TG trained a fishing community to build a dozen Biorock reefs to restore their own coral reefs, which were dynamited, dredged, turned into an airstrip by the US military in 1943, and never recovered. Fishing villages all around Vanuatu, concerned about their reefs, have tried all other methods of coral reef restoration, and found that they all failed. Now, having seen the results of the Biorock pilot projects, they all want training too to develop their own community reef fisheries mariculture projects. Their eagerness to learn methods to be more productive and less destructive is incredible, and we are delighted to help them!
TG’s family has worked with local Aboriginal communities to document the health of their corals on the Great Barrier Reef for generations, and have photos of the same reefs from 1927, 1950, 1967, and 1998. We need to repeat these photos and videos again, now that most of the corals have died from global warming in 2017, exactly as we had predicted would happen. We will work directly with the Kuku Yulanji Aboriginals of the Daintree Forest, owners of Low Isle, where we stayed and photographed each time, to restore their dead coral reefs and establish their Sea Rights to all of their territory, underwater as well as above. TG is a hereditary member the Dhuwa Yolngu Aboriginals of Arnhem Land, the oldest culture in Australia, which has preserved knowledge of all the places they lived in the last 50,000 years, including those drowned by the sea after the last Ice Age.
GEOTHERAPY GLOBAL CLIMATE REGENERATION STRATEGIES
GCRA is helping The Commonwealth Secretariat (CS), 52 countries with 2.5 billion people, a third of the Earth’s population, develop a strategy of Regenerative Development to Reverse Climate Change, for presentation to the United Nations Framework Convention on Climate Change in December. This aims to stabilize CO2 at pre-industrial levels in decades, to prevent runaway climate change impacts. Our Geotherapy book and recent FAO papers on factors controlling rates of regenerative drawdown and long-term storage of CO2 in soils provide the scientific basis of the strategy. We have also developed superior Biorock electric restoration methods for mangroves, seagrasses, and salt marshes, whose peat soils are the most cost-effective carbon sinks on the planet.
There won’t be any operational funding for strategy development or implementation until after approval by the Commonwealth Secretariat in June, and UNFCCC in December, but the CS has asked TG to advise them on marine issues and present the scientific foundations of the strategy to the UN Food and Agriculture Organization Global Symposium on Soil Organic Carbon in March 2017 in Rome, the Society for Ecological Restoration Conference in Brazil in August, and at UNFCCC.
It will also be very important to make other such strategically critical presentations where needed to help support the strategy development in the coming months, especially with the majority of the Commonwealth nations, the Small Island Developing States (SIDS) of the Pacific, Caribbean, and the Indian Ocean. GCRA has worked directly on coral reef issues in almost every single SIDS in the Pacific, Indian Ocean, and the Caribbean, and has close contacts with may SIDS environmental groups and governments, starting with Jamaica, where GCRA originated. GCRA is therefore extremely familiar with the local environmental management problems and can identify the specific locations that would most benefit from regenerative development strategies in each of these countries.
HIGH IMPACT DOCUMENTARY FILMS
GCRA, and its partner, the Soil Carbon Alliance, seek funding to complete three documentary films, and books, of critical importance to climate strategies:
DIRT RICH by Marcelina Cravat, Passelande Films, Berkeley. Shows how soil carbon is being increased by many methods around the world, and how it can reverse global climate change. Filming is already complete, and funding is needed for final editing and production phases, including soundtrack, narrators, promotion, etc. We have previously collaborated on ANGEL AZUL, about underwater art, tourism, coral reefs, dolphins, algae, and sewage in Cancun.
CORAL GHOSTS by Andrew Nisker, Take Action Films, Toronto. The history of coral reefs, the most climatically threatened ecosystem, from life to death, and hopefully to regeneration. Funding is needed for filming at critical sites around the world, in the Great Barrier Reef, Jamaica, Bahamas, Indonesia, Micronesia, Panama, the Red Sea, and others to compare with our underwater photograph collection, the world’s largest and oldest, in order to understand the causes of the changes at each reef, and show how to reverse them. We will focus on training local Indigenous fishing communities to restore their coral reefs and fisheries, especially the Kuku Yulanji Aboriginals of the Great Barrier Reef. We have previously collaborated on GROUND WARS, in production for The Nature of Things with David Suzuki, on health and environmental impacts of golf course chemicals on coral reef and human health.
SCIENCES OF LIFE, TECHNOLOGIES OF DEATH: THE 1970 MIT STUDENT STRIKE AGAINST WEAPONS RESEARCH AND THE MOVEMENT FOR SOCIAL RESPONSIBILITY IN SCIENCE by Tom Goreau & Videosphere, Cambridge, MA. MIT students in 1970 went on strike specifically over the issue of weapons research on campus, at a time when all other campuses were focused on the Viet Nam War. MIT succeeded in stifling debate on the issue by expelling the student leaders, but the undergraduate student, graduate student, faculty, and administration led the formation of many organizations focused on the social responsibility of science and engineering. The moral issues raised nearly 50 years ago are just as relevant today in the era of mass bombing and global warming, but have been effectively ignored since 1970. The various points of view of the many participants from all sides are being explored by interviews with the surviving leaders of the 1970 events on all sides.
GLOBAL CORAL REEF ALLIANCE – SOIL CARBON ALLIANCE
GCRA/SCA is a global non-profit network of volunteers working with essentially no funding on direct action projects with local communities to protect and manage coral reefs, and all other ecosystems, all around the globe. For more than 25 years GCRA has provided cutting edge research on community-based ecosystem restoration and management in developing countries and indigenous communities, the impacts of global climate change on ecosystems, and helped invent important new technologies to reverse them and regenerate the ecosystem services providing our planetary life support systems, founded on restoration of natural biogeochemical recycling processes.

DEC Approves MacNeil Park Outfall Pipe
BY JAMES FARRELL
Staff Writer : Queens Tribune
A proposed city Department of Environmental Protection (DEP) storm water outfall pipe on the northern shoreline of College Point’s MacNeil Park has been granted a permit by the state Department of Environmental Conservation (DEC), despite the months-long outcry by local environmentalists.
The pipe would empty out near DEC-protected wetlands that are currently being restored and preserved by the College Point-based conservation group the Coastal Preservation Network (CPN). CPN has been restoring the sea marsh at the site for years, growing an ecosystem of oysters, mussels and shoreline grasses that the group argues helps reduce shoreline erosion caused by increasing sea levels. In October, the group led a protest, claiming that pollutants found in the stormwater flowing from the pipe could kill the carefully preserved marine life.
But the DEC disagreed after responding to 222 public comments. The permit was effective as of April 13.
“DEC carefully analyzed the substance of the city’s application, application materials and plans for the outfall; conducted multiple site visits to inspect the project area; and reviewed the responses shared during the public-comment period for this project—and found no potential for significant adverse impact to wetland habitat, oysters or water quality would result,” said DEC spokeswoman Erica Ringewald.
The pipe is part of a $132 million infrastructure project to reduce sewer drainage into Flushing Bay. Currently, three combined sewer outfalls in different locations overflow into the bay during heavy storms, releasing untreated sewage and rainwater. The new pipe, which would allow for the decommissioning of the three combined outfalls, would emit only stormwater—not sewage—creating less pollution in the bay overall.
But while CPN president and marine biologist James Cervino approved of the reduced sewage, he argued that the stormwater would still carry pollutants that would fall directly into the sensitive ecosystem.
“It’s not pretty little rainwater that comes off people’s drains,” Cervino said. “It goes into the street. There are oil slicks in the street; there’s animal feces in the street; there’s salt, de-icing chemicals on the street.”
In its response to public comments, the DEC acknowledged that the stormwater has some pollutants, but added that those pollutants are already being discharged at the site and that the water would be generally cleaner than water emitted from the combined outfalls.
But as the Queens Tribune reported in March, Cervino’s own tests of water near clogged storm sewers in College Point found levels of lead and zinc that exceeded regulatory levels. This is a sign, he argued, that the water entering the pipes may not be as harmless to the habitat as the agencies let on. He argued that the public comments were made by specialists in marine immunology who know the risks of such pollutants firsthand, and feared that no such specialists were consulted by the DEP.
Among the public comments was one from Dr. Thomas Goreau, who has worked on the project with Cervino, serves as president of the Global Coral Reef Alliance and was an advisor to the United Nations.
In an interview with the Queens Tribune, Goreau explained that the project was the “most successful that’s ever been done of its kind” since it pioneered a new method using solar panels to speed up the growth of oysters, salt marsh and mussels. Since those habitats can slow erosion, Goreau argued that the technique could provide an alternative to sea walls and other costly artificial structures for protecting shorelines from global sea rise. He said that the pipe would destroy his group’s work.
“I don’t know how they plan to absorb the toxic levels, illegal levels, of pollutants that are going to be in storm runoff, even if no sewage goes into it,” Goreau said.
The DEC told the Queens Tribune that “trained biologists” from the Division of Marine Resources and Marine Habitat Protection carefully reviewed the application and conducted site visits. The agency also added that the plan includes a splash pad—which serves to prevent erosion caused by the outflow of water—and 8,607 square feet of new sea grasses extending west of the new pipe, although Cervino and Goreau both said that pollutants could threaten the sea grasses already at the site.
Both Cervino and Goreau had also suggested that the outfall pipe be extended a few 100 feet farther out, so that the stormwater runoff doesn’t fall directly onto the habitat. In response to these comments, the DEC argued that installing the extended pipe would cause more extensive damage.
“But they’d avoid all the long-term damage that’s going to happen from destroying the environment right at the coastline,” Goreau countered.
In a statement, Councilman Paul Vallone (D-Bayside) said that he was unhappy that the DEC had not agreed to extend the pipe.
“While we appreciate the closing of the combined sewer overflow, which will increase the quality of the water in the area, the situation could have been further improved by including any of the pretty basic concessions that were ignored,” Vallone said.
On Monday, state Sen. Tony Avella (D-Bayside) said that he was also disappointed, but understood the situation.
“I trust DEC,” Avella said. “I spoke to the commissioner several times about it and he assured me they did a careful review of the application and permit.”

To: NYS DEC Commissioner Basil Seggos State Senator Tony Avella
New York City Department of Environmental Protection is racing ahead with irresponsible plans to destroy the most successful oyster, mussel, and salt marsh restoration project ever done in New York City, or anywhere else.
These projects, approved by New York State Department of Environmental Conservation, have for 10 years pioneered new methods for restoring these valuable ecosystems, providing habitat for birds, fish, and shellfish, protecting shores from erosion, and improving coastal water quality, which could save the City billions of dollars in adapting to and mitigating global warming and global sea level rise (please see current photos attached).
The MacNeil Park projects have shown for the first time how to restore vibrant marine ecosystems to barren shores where everything had died from toxic waste dumping at the site for more than 50 years. They not only restored life to a wasteland, but showed for the first time how to grow these organisms under extreme stress conditions that they normally could not survive. Our team is now expanding the project to fill in all the gaps.
10 years of work will be destroyed if DEP puts the storm drain where they intend. This will not only flush water shown by chemical analysis to have illegally high concentrations of toxic lead, copper, zinc, hydrocarbons, and untreated sewage, but the water flow will wash away the beach sediment and cause severe local coastal erosion at a site that is a designated public recreational area and entry way for kayaks.
Using the Biorock restoration method, we had 100% survival of oysters during the winter when 93% of control oysters died. The few surviving control oysters stopped growing in winter, and their shells were chalky, crumbly, and dissolving due to cold acidic water, but Biorock oysters grew all winter, and their shells were bright and shiny with no dissolution.
The Biorock restoration method has grown salt marsh lower in the intertidal zone than salt marsh grass can tolerate, it grows taller, faster, greener, and spreads faster than controls, grows back in larger spreading patches after every winter when controls die, and has prolific root growth and mussel populations which bind sediment and prevent erosion by waves.
The mussel growth has been so extraordinary that in a few years we have raised the height of the beach where we are growing them by up to a foot, much faster than the rate of global sea level rise, about an eighth of an inch a year. Therefore, we are able to grow beaches upwards at places where they are now washing away from erosion.
Oysters have spontaneously settled near our projects, but not away from them, showing that oyster settlement is increased by the Biorock process. These oysters have shown exceptionally high growth and survival.
These incredible results show for the first time that it is possible to extend salt marshes seaward to protect coasts from erosion. All salt marshes in the US are rapidly eroding and collapsing into the sea due to global sea level rise and increased storm wave strength caused by global warming. Jamaica Bay is the worst example of this. The methods pioneered at the McNeil Park project could save Jamaica Bay salt marshes, and help protect Kennedy Airport from flooding by the sea and storm surges (remember Sandy!).
This destruction of a historic restoration project is entirely un-necessary! There is an existing storm drain at the site that runs out past the project to the low tide mark, built long ago to prevent contaminated water washing directly onto the beach. But instead of using it or upgrading it, DEP plans to dump polluted water directly at the shoreline high tide mark, and flush away 10 years of extraordinarily successful work with polluted water!
The bulldozers are right at the edge of the project, ready to move into action unless DEC can get them to responsibly act to save New York City’s precious green shorelines! We urgently appeal for your help to save the projects that will make New York the leader in natural shore protection.

Scientists to use solar energy to regenerate locally extinct corals
Marine scientists will use solar energy for the first time in India to regenerate corals that become extinct from the Gulf of Kutch off the Gujarat coast thousands of years ago.
Scientists across the world are trying to come up with various methods that can regenerate bleached and locally extinct corals. One such technique, popularly called biorock, has helped scientists in many countries to conserve and protect coral reefs also known as underwater gardens.
Pemuteran in Indonesia has the world’s largest coral regeneration project where biorock has been used.
India has four major coral reefs — Andaman and Nicobar Islands, Lakshadweep, Gulf of Mannar and Gulf of Kutch. While the reefs in Andaman are considered the richest and most diverse, the ones in Kutch area are the poorest. Only 30% of the coral in Kutch area are alive, albeit in a degraded condition.
“We have identified a site in the shallow waters near Shivrajpur in Dwarka area of Gujarat where the pilot project could be carried out. There are some challenges such as siltation and high tidal fluctuations which we have to address. Using solar power is under consideration and the technical details are being worked out,” Shyamal Tikader, chief conservator of forest in Gujarat, said.
Coral reefs are like underwater gardens and one of the most diverse ecosystems on earth providing food and shelter to millions of species. They are under threat because of climate change-induced ocean acidification, pollution and human activities among others.
“We will be using electricity to re-grow corals for the first time in India. These corals had become locally extinct from the Kutch region long ago but can be found in other reefs across India. Plans are going on to start the pilot project in April with the help of solar power,” Chowdula Satyanarayana, a coral scientist with the Zoological Survey of India (ZSI) who is leading the project, said.
A steel structure would be first installed on the seabed and could be of any shape ranging from a simple arch to as complex as that of a motorcycle. Cables would connect the structure to a power source such as solar panels, which would float on the surface of the sea.
Very low doses of electricity – less than 12 volts – would then be run through the structure via the cables. The electricity would trigger a chemical reaction in the sea water, similar to that of electrolysis. Minerals, mostly calcium carbonate (limestone), would get deposited on the steel structure.
“Divers would attach fragments and twigs of corals brought from other reefs like Gulf of Mannar to the steel structure. The structure, which now will have a layer of limestone on it, can act as a base for the corals to grow again,” Satyanarayana added.
Scientists have selected five species of branching corals for the project which grow very fast and once used to dominate the Kutch reef. The zooxanthellae – tiny plant-like organisms that make live corals colourful – return automatically helping the corals to thrive.
The coral polyps, which are animals, and zooxanthellae share a mutual relation. The corals provide shelter to the zooxanthellae and compounds these tiny algae need for photosynthesis. The algae in return produce oxygen and help the corals to remove wastes.
They also supply them with glucose and amino acids which the corals use to make fats, proteins and carbohydrates and even calcium carbonate. Most importantly, the zooxanthellae give colours to the otherwise white corals.
Under stressful conditions such as pollution, high temperature and ocean acidification among others, the coral polyps expel the zooxanthellae. Without the colour, the corals turn white a process which is popularly called coral bleaching.
With a base of limestone and low doses of current supplied at regularly, the corals could grow nearly 20 times faster and have better chances of survival, experts claimed.
“It is just like giving oxygen to an athlete while he is running. With oxygen, he would be able to run faster and for a longer period. Similarly, it has been seen that providing small doses of electricity helps the corals to recuperate faster and survive longer,” Satyanarayana said.
The ZSI is trying to rope in Thomas Goreau, a US-based coral expert who along with Wolf Hilbert developed and patented the biorock method.
“We have helped many countries in setting up biorocks. Next, I would be providing special materials and help Satyanarayana. Biorock doesn’t just help corals but have helped to restore the fish population, which often takes shelter in these structures,” Goreau told Hindustan Times over email.
Presentations by Tom Goreau, Coordinator, Soil Carbon Alliance
Coastal Preservation Network President James Cervino has tested wastewater that would go into the Department of Environmental Protection’s planned stormwater outfall for MacNeil Park in College Point, and he isn’t happy with the results….
For nearly 30 years we have been able to predict mass coral bleaching accurately with the Goreau-Hayes Satellite SST HotSpot method (Goreau, 1990 US Senate Hearings on Climate Change; Goreau et al., 1993; Goreau & Hayes, 1994). We have routinely predicted, and confirmed, bleaching events that have never been documented by the coral list or NOAA. There were many such bleaching events last year in places that were hotter for longer than the GBR, but dive shops are now routinely concealing bleaching as “bad for business”.
In one large area of the Pacific where bleaching was certain last year, only one single dive shop would admit it had happened, but did not send photos, not one of the other dive shops would respond to a request for confirmation if bleaching was happening.
The NOAA data base and the web site that documents the HotSpot data is still up, but this may simply be an accidental oversight, as all US Government sites documenting climate are being shut down because the data contradicts the politically-motivated lie that climate change is not happening!
It is very important that other countries take the data leadership role that the US regime is now destroying, because otherwise no-one will have warning when their corals are about to bleach or die.
We can only hope that the European Union, Japan, and China take up the responsibility of real time HotSpot mapping needed to provide alerts.
If there is no database documenting coral death from heat stroke, Governments will continue to falsely say that 2 degrees C further warming is “acceptable”, they will continue to sentence coral reef ecosystems to death, and billions of people living along low lying coasts to become desperate migrants, so many that no walls will be high enough.
Below is the latest Pacific HotSpot map. In case it is the very last one that we will ever see it is important to realize that a large area of the South Pacific from the Great Barrier Reef, New Caledonia, Vanuatu, Fiji, Samoa, and Tonga is warming rapidly and now is at or just below bleaching thresholds, although of course it will take about a month at present conditions for it to be generally noticeable, sooner if it continues to warm up, as normal at the very start of the hot season.
The current rate of warming is greatest in the GBR, bleaching temperatures have been reached unusually early in the season, and the hot season in Australia has not even started yet!
Barring miraculous cooling, there may be little coral left in the GBR later this year.
Ray Hayes and I have always pointed out that it is extreme events that cause bleaching, not mean changes, and the model based predictions of bleaching, which are based on mean rates of change, which say that bleaching might be a problem in the GBR in another 50 years, have proven falsely optimistic yet again.
When lies trump truth, the new dark ages begin.
