The lawsuit by Centro de Incidencia Ambiental (CIAM) against dredging that would damage coral reefs in front of the Panama Canal (based on GCRA reef surveys with the Galeta Marine Laboratory) was admitted by Panamanian Courts on 8 January 2018. This means that the construction works in the port must be suspended while the Court provides a final merits decision. Because we filed an amparo de garantías action, we argued infringement of the constitutional rights to a healthy environment, sustainable development and health. Because of these arguments, once this type of lawsuit is admitted it immediately suspends the legal effects of the resolution that approved the project’s EIA until a final decision is made by the Supreme Court.

A Case Study in Bali Province during the last seven years, a thesis dissertation at Xiamen University, Fujian, China by Sandhi Raditya Bejo Maryoto, Biorock Indonesia Maluku Project Officer, covers the rapid expansion of coral exports for the aquarium trade in Indonesia in general, and Bali in particular.
Indonesia plans to end export of wild corals and switch to 100% export of verifiably cultured corals by 2020. With the banning of coral exports by the Philippines, and most recently by Fiji (BBC Article), Indonesia now has a near-complete monopoly on global aquarium coral exports, so now would be a good time for Indonesia to accelerate the phase-out of wild coral exports.
The world ornamental coral trade continues to grow as the result of increasing demand for aquarium industries. Indonesia as a major exporter has distributed corals worldwide with the USA as the biggest market, followed by 87 other importing countries. Ditjen KSDAE (Directorate General for Conservation of Natural Resources and Ecosystem) of MoEF (Ministry of Environment and Forestry) and P2O-LIPI (Research Center of Oceanography – The Indonesian Science Institution) was mandated as a management and scientific authority, respectively, in this curio trade management in Indonesia which is highly referred to CITES provisions. The trade entangles numbers of fishermen, middlemen, wholesalers, and coral companies in advance of exportation. As reported by CITES, a total of 25,569,984 corals were traded from Indonesia in 1985 until 2014. More than 49% (12,719,104 pieces) of all corals were exported to the USA in the same period. As the trade directed to be more sustainable, cultured corals grew steadily during the last decade. BKSDA Bali (Conservation and Natural Resources Agency of Bali Province) also reported similar results in regional coral exportation from Bali. There were 9,583,821 pieces of ornamental corals, mostly were cultured corals, traded by coral companies based in Bali during 2010 – 2016, with annual growth rate of 19.06%. It constituted almost 60% of total Indonesia exportation and was carried out by 25 coral companies. Existing management measures e.g. quotas, licensing system, and spatial management through no-take zones have been put into effects despite still requires various improvements. More comprehensive studies and scientific data are therefore essential in decision making process to set out adaptive management strategies and thus ensuring sustainable coral trade.
An exceptionally healthy coral reef directly in front of the Panama Canal breakwater is threatened by dredging for the new Isla Margarita Port Terminal. Unless strict measures are taken to prevent mud from getting out of the Eastern Channel onto the adjacent coral reef, Panamanians stand to lose this habitat that is part of their national heritage.
Environmental impact assessments made for the port development only considered dead previously dredged areas inside the breakwater, and completely ignored the healthy coral reefs less than a hundred meters away, connected by an open channel to the dredging and landfill sites.
A survey by the Global Coral Reef Alliance (GCRA) and the Galeta Marine Laboratory of the Smithsonian Tropical Research Institution (STRI), at the request of Centro de Incidencia Ambiental (CIAM), found a healthy coral reef with high living coral cover right in front of Isla Margarita and the eastern end of the Panama Canal breakwater. These reefs are not mentioned anywhere in the port’s Environmental Impact Assessment (EIA): the EIA mentions only dead habitat in the area, which would not be affected from dredging nearby. The living coral reefs are only about 100 meters away from the Port dredge and filling operations.
This reef is close to the Isla Galeta Protected Area, and strong measures are needed to protect the highly vulnerable corals from suspended sediments.
This report, and the photos and video attached to it, describes the health status of this extraordinary reef (figures below) and the measures needed to monitor and protect it.
The full report, with photographic and video documentation can be seen below.
After the survey of Isla Margarita reef was done, the project proponents announced without warning that they had made a mistake: they needed 16 times more dredging material to complete the project than they had projected, and most of the required sand for the filling operations would be dredged in Nombre de Dios. Unfortunately, Nombre de Dios represents the center of the best shallow fringing coral reef flats in the entire Caribbean and is a site of global biodiversity importance.
Two new Global Coral Reef Alliance videos answer the question many people have: what happens in a hurricane? Here we show that Biorock reefs hit by the eye of three of the strongest Caribbean hurricanes, Hanna, Ike, and Irma, suffered almost no physical damage and built up sand around them during the event.
In contrast, solid concrete objects nearby caused so much scour and erosion around and under them that they sank into the sand. Solid breakwaters cause reflection of waves at the solid surface, concentrating all the wave energy in one plane, which causes sand to wash away in front of the structure, then underneath, until it is undermined and collapses. This is the inevitable fate of any vertical seawall, so they need constant and costly repair and replacement. After Hurricane Andrew every single shipwreck in South Florida was torn apart or moved great distances due to the strong surface drag. Not one remained intact.
Biorock electric coral reefs can be any size or shape. For growing corals, we make open frameworks, so the corals can benefit from the water flow through the structure, just as they do in coral reef. As a result of their low cross section to waves, they dissipate energy by surface friction as waves pass through them, refracting and diffracting waves rather than reflecting them. Their low drag coefficient means that they survive waves that would move or rip apart a solid object of the same size.
Here we show what happened to Biorock reefs after the most severe hurricanes ever to hit Saint Barthelemy and Grand Turk. Incredibly, there was little or no physical damage to the structures or to the corals, even though these structures were not welded, simply wired together by hand, and they were not physically attached to the bottom, simply sitting on the bottom under their own weight, attaching themselves to hard bottoms and cementing sand around their bases through growth of limestone rock over their surfaces.
These astonishing results follow our previous video showing the record recovery of severely eroded beaches behind Biorock reefs:
It is important to realize that neither rocks nor structures exposed at low tide shown in this video are an essential part of the method. Almost all of Biorock structures are completely submerged and have no rocks. At Pulau Gangga this design was used to protect the beach from storms at high tide, and effectiveness was more important than aesthetics to the Resort, so they opted not to have what most people want: an invisible watchman that you can’t see at low tide sunset!
In addition, Biorock electric reefs greatly increase the settlement, growth, survival, and resistance to stress of all marine organisms, with only a single known exception: predatory sharks avoid electric fields that confuse them, protecting people and sharks from each other (Uchoa, O’Connell, & Goreau, 2017). In 2016 there was nearly complete survival of Biorock corals during severe high-temperature events that bleached and killed more than 95% of corals on nearby reefs.
Our results show that Biorock electric reefs are the most cost-effective method for saving corals from global warming, restoring reef communities (whether corals, oysters, or mussels), and protecting coastlines from erosion and global sea level rise.
Increasing stress from global warming, sea level rise, acidification, sedimentation, pollution, and unsustainable practices have degraded the most critical coastal ecosystems including coral reefs, oyster reefs, and salt marshes. Conventional restoration methods work only under perfect conditions but fail nearly completely when the water becomes too hot or water quality deteriorates. New methods are needed to greatly increase settlement, growth, survival, and resistance to environmental stress of keystone marine organisms in order to maintain critical coastal ecosystem functions including shore protection, fisheries, and biodiversity. Electrolysis methods have been applied to marine ecosystem restoration since 1976, with spectacular results (Figures 1(a)-(c)). This paper provides the first overall review of the data. Low-voltage direct current trickle charges are found to increase the settlement of corals 25.86 times higher than uncharged control sites, to increase the mean growth rates of reef-building corals, soft corals, oysters, and salt marsh grass— an average of 3.17 times faster than controls (ranging from 2 to 10 times depending on species and conditions), and to increase the survival of electrically charged marine organisms—an average of 3.47 times greater than controls, with the biggest increases under the most severe environmental stresses. These results are caused by the fundamental biophysical stimulation of natural biochemical energy production pathways, used by all organisms, provided by electrical stimulation under the right conditions. This paper reviews for the first time all published results from properly designed, installed, and maintained projects, and contrasts them with those that do not meet these criteria.

Low-voltage direct current trickle charges using Biorock electrolytic technology   grow limestone structures
of any size or shape in the sea and produce the only self-repairing marine construction material that gets
stronger with age , and grows breakwaters capable of rapidly growing back severely eroded beaches . But
in addition to physical benefits the process also has profound stimulatory effects on all forms of marine life.
Biorock structures have been repeatedly shown to greatly increase the settlement, healing, growth, survival, and
resistance to stresses such as extreme high temperatures, sedimentation, and eutrophication in stony corals -, soft corals , oysters -, sea grasses , and intertidal salt marsh grasses . Many other organisms, including clams, tunicates, sponges, and fishes have also been observed to greatly increase their populations in electrical fields, but few measurements have been made on them to date. This review summarizes the available data on the effects of low-voltage direct current electrical stimulation on growth rates, survival, stress resistance, and physiology, which suggest the mechanism is a completely general one that benefits all organisms . Results from projects that were properly designed, installed, and maintained are included in the main part of this paper. Because understanding the causes of negative results play an important role in the scientific method, projects that do not meet those criteria of proper design, installation, and maintenance are discussed separately.
2. The Impact of Electrical Stimulation on Marine Organisms
2.1. Published Results from Properly Designed, Installed, and Maintained Projects
The very first Biorock project, built at Grand Isle, Louisiana in 1976, was completely covered by multiple layers of spontaneously settling oysters that grew to adult size in about 3 months . Recent Biorock projects in New York City show dense spontaneous settlement of oysters on rocks near Biorock structures. Nevertheless, no controlled studies of oyster settlement have yet been conducted. By the late 1980s it was found that electrically stimulated corals grew 3 – 5 times record rates for their species, even under conditions of severe stress. Since then hundreds of projects have been built all across the Caribbean, Pacific, Indian Ocean, and Southeast Asia, with most projects being in Indonesia, the global center of marine biodiversity. While slowly growing Biorock structures have been densely covered with hundreds of spontaneously recruiting corals  , only two studies have documented coral settlement on them  . When these are compared to spontaneous recruitment of corals in natural habitats in the same units (recruits per square meter per month) the rates of settlement on electrically charged Biorock are found to be 1 to 4 orders of magnitude greater (Figure 2(a)), with a mean of 25.86 times higher than those reported from field settling experiments.
Growth rates of reef building hard corals -, gorgonian soft coral , oysters -, and salt marsh grass (Spartina alterniflora)  have been quantitatively compared on Biorock with identical clones off Biorock
in the same habitat. The results show that the electrically stimulated organisms grow typically 2 to 10 times faster (Figure 2(b)), with a mean of 3.17 times greater than controls. In addition hard and soft corals that have
been collected naturally broken and badly damaged are observed to heal completely, release little or no mucus, and regain bright color and polyp extension within a day, while controls remain pale and continue to look injured
and release mucus for two weeks . Corals in electrical fields are observed to bud and branch more densely  . This is reminiscent of the well known role of DC electrical fields in healing ruptured cellular membranes and cuts in the skin of organisms: if the polarity is correct the cut rapidly heals and closes, while if it is reversed the cut opens up . Survival of hard corals -, soft corals , oysters -, and salt marsh grass  in electrical fields compared to un-electrified controls also show many times higher survival (Figure 2(c)), with a mean of 3.47 times higher than controls. This is especially the case in extreme stress conditions from excessively high temperatures, sedimentation, or eutrophication, when almost all the controls die, but most of the electrically charged organisms survive. For example in the severe 1998 Maldives bleaching event Biorock reefs had 16 to 50 times higher coral survival than surrounding reefs, and every single control coral transplanted onto cement structures died . In the 2010 Thailand bleaching events corals bleached less (in some cases not at all), recovered faster, and had much higher survival than the same species of corals on surrounding reefs . Similar results have been seen with oysters , salt marsh grass , and seagrass . Control oysters in New York City nearly all died over a severe winter, and the shells of the survivors shrank in size because they were etched and dissolved from acidity caused by increased CO2 solubility in cold water. In contrast Biorock oysters continued to
grow throughout the normally dormant period, and their shells were shiny with no signs of dissolution from acidity . This is in part because the Biorock electrolytic process generates net alkalinity, and so counteracts acidification . A comparison of 6 genera of corals grown on Biorock with genetically identical clones in the same habitat  showed that electrically stimulated corals had higher densities of the symbiotic alga Symbiodinium sp. (Figure 3(a)), even higher Symbiodinium cell division rates as measured by mitotic indices (Figure 3(b)), but had generally lower chlorophyll per Symbiodinium cell (Figure 3(c)). This is analogous to the lowered chlorophyll content of corals exposed to high light, which is interpreted as a mechanism to prevent excessive photosynthetic production and symbiotic alga growth -. The greatly increased growth rate of corals with electrical stimulation appears to occur despite less dependence on the symbiotic algae, and therefore is a direct effect of the electrical field itself.
All of these phenomena indicate that electrical fields in the right range greatly stimulate the health of marine organisms. These effects are not residual, they occur only when the electrical field is on (Figure 4(a)). These results are no surprise, since all forms of life from bacteria on up maintain a roughly tenth of a volt potential difference between the outside of the cell and the inside, and use electron and proton flow along this voltage gradient to make ATP and NADP, the fundamental energy and reducing currencies of all life. ATP production and protein synthesis are both directly stimulated by DC electrical currents over a very broad range spanning orders of magnitude , increasing with current to a maximum and then decreasing at excessive levels (Figure 4(b)). 2.2. Results from Improperly Designed Experiments This section discusses published results from projects that do not meet the criteria of proper training, materials, design, installation, and maintenance according to the inventors of the electrical stimulation method. All have failed to get the results achieved by those with proper training and materials, for several different reasons. As
there are several different causes for their failure to achieve prime results, these inappropriate projects are reviewed below by major categories of the flaws in their design or execution.
2.2.1. Mistake -1: Current Reversed
In these projects the power leads are connected backwards. Instead of the cathode being protected from corrosion, it rusts very rapidly instead, and the anode, instead of being clean, is instead heavily overgrown by rapid growth of soft minerals. Sometimes it takes months before they realize their mistake, and often the error was only recognized much too late when the author visited and pointed it out. These mistakes can easily be prevented by promptly sending photos for advice. In some cases reports based on this mistake have been published claiming that the method is a total failure. A report by the Texas A&M University Galveston Coastal Geology Laboratory was paid for the State of Texas General Lands Office (GLO), in order to see if electrical methods could protect steel with mineral coatings, as had been shown by Hilbertz in the 1970s. Texas A&M found instead that the charged structures rusted even faster than the controls! They never realized their mistake, nor apparently did Texas GLO.
2.2.2. Mistake 0: No Current
This can result from power supply failure or from cable breakage.
In some of these cases the project was properly designed and installed, but those running the project failed to realize that it was not under power and send photos to the author for confirmation and advice on how to fix it. Some of these continued making measurements for up to year not realizing that the project was not under power, and the mistake was only realized afterwards when they finally sent the first photographs to the author, who immediately recognized they were not receiving electrical current. That is why even trained groups are advised to send frequent photos for advice.
Other cases were by untrained imitators using incorrect design and materials. These failures were largely caused by power supplies burning out, electrical cables breaking, or bad contacts. Most such failures were caused by extreme storm events, such as hurricanes, typhoons, and cyclones, and were not properly diagnosed or repaired. In other cases they resulted from deliberate destruction by people running boats over the cables, breaking cables by dragging anchors over cables, by people dumping anchors on top of projects accidentally or deliberately, or saboteurs who cut cables for bizarre reasons of their own, usually involving a personal grudge against a local partner rather than the project itself. Unfortunately several projects that received no current resulted in published theses and papers.
One example is a thesis project by Zaidy Khan at the University of the South Pacific, which found no difference in growth rates of corals on structures which were thought to be under power but which in fact were not, and control structures known to receive no power.
The same error occurred in a thesis project by Andrew Taylor of James Cook University, supervised by Bette Willis, who sought to compare coral growth on structures with and without power. Taylor did not build any electrified structures, he simply used one of our field sites without permission, which his thesis advisor did not seem to realize was fundamentally unethical. The structure he thought was under power was in fact not, due to a burned out power supply that had not been repaired or replaced. In addition Taylor’s control corals died from disease, but a poster was presented anyway at the International Coral Reef Symposium claiming that Biorock corals did not grow faster than controls.
Another experiment done by Bogor University at Pramuka Island in the Seribu Islands north of Jakarta was victim of deliberate turning off of the power. The local power supply was in a commercial restaurant that was paid for supplying power, but which in fact turned the power off except during short visits by students making measurements. The interpretation of several Master’s theses was compromised by failure to realize what had happened until later.
In several cases groups in places like Thailand, the Philippines, Germany, Japan, the United States, and other places, who falsely claim to be trained in Biorock methods have been making unauthorized projects that have been complete failures. Their pitiful results are an obvious failure to all visitors, and an embarrassment because the imitators then say the method doesn’t work, not that they aren’t trained to do it properly.
2.2.3. Mistake 1: Current Too Low
This mistake results from powering too large an area with too small a power source, or failure to recognize that cables are broken or inadequate. One example comes from Terlouw , who reports measurements made on a project in Ko Tao, Thailand that was partially installed, but whose installation was never completed to standards. As a result of inadequate and broken cables the project received only a little power in the first year. In the second year new cables were installed and a failed power supply replaced so the project received power, but in the third year the cables broke and or the power supply failed, so only a small trickle or no power reached the project. These conditions were identified by the author from photographs sent from the project, but were not recognized by Terlouw, who reported that corals on Biorock grew faster than control corals by a factor of 1.54 in Year One, by a factor of 5.04 in Year Two, and by a factor of 1.33 in Year Three. Terlouw, not recognizing the cause of the variations, suggested that benefits are mixed, but our interpretation is that the higher results in Year 2 are due to that being the only year with adequate power, while Year 1 and Year 3 were underpowered, resulting in lower rates.
A similar mistake was made with oysters by Piazza et al. . In this particular case the oysters thought to be getting electrical current were in fact getting almost none at all, because flawed experimental design concentrated the current onto fresh pieces of bare steel. Piazza et al. found that the oysters that they incorrectly thought to be under power grew only 1.15 times faster than controls.
2.2.4. Mistake 2: Current Too High
Over-charging has been known to cause negative effects from the very start, but most groups that set up experiments without proper training or materials use high power to get quick results. As shown in Figure 4(b) of this paper, excessive current causes negligible benefits, and if too high, causes negative effects, killing corals. Unfortunately most of those who get negative results due to overcharging do not realize their error, and many of them have published their results anyway. This mistake is the cause of the very poor results reported by Schuhmacher, Schillak, Van Treeck, Sabater, Yap, Eggeling, and their colleagues -. Since these authors did not realize their mistakes and published negative or minor results, it has been widely claimed that the method does not work, but in fact their poor results were entirely due to lack of proper training, experimental design, materials, etc. Such mistakes are even worse when done in a closed system tank. As a result of their overcharging the corals had only very small increases in growth rates, or they bleached and failed to grow entirely, or died.
2.2.5. Mistake 3: Ethical
Borrell et al.   reported that one coral species grows a bit faster with electricity but that another species had its growth reduced and inhibited by the electrical field  . In fact, the alleged reduction of one species’ growth was for a completely different reason: terminal phase male parrotfish established their breeding territories on the Biorock project, and marked them by biting off all the growing tips of that one species only, while ignoring them in the control site. The author of this paper personally set that project up, and documented the cause, but this was completely and knowingly ignored by the authors of the report, causing deceptive and false conclusions.
These results all point in the same direction: low-voltage trickle charges can greatly enhance the health of marine organisms. Voltage gradients in the right range appear to create the ideal biophysical conditions for the creation of biochemical energy, stimulating healing, growth, survival, and resistance to stress. The external field maintains the cell membrane gradient and greatly reduces the need for cells to spend a large part of their energy pumping electrons, protons, and ions to maintain the gradient, freeing this energy for metabolism, growth, and resisting environmental stress.
Unfortunately many people copying the Biorock method think they can do so without training. The results of improperly designed, installed, and maintained projects set up by people without training using improper materials always fail to replicate the results of projects by trained people using approved methods and materials, for several obvious reasons. These people inevitably blame the technology itself and not their lack of training. Almost every data point in these graphs represents populations of different species grown in the field under different electrical conditions, most of which are likely to be suboptimal. For example oyster growth rates next to a former toxic waste dump in New York City increased with current, up to 10 fold (NB, length increase only, the volume increase is a thousand fold), even though they were getting power less than a quarter of the time, and probably would have grown even faster with more power . Much more work is needed to find out the optimal conditions, which are likely to be subtly different for each species. It has not escaped our attention that because membrane electro-chemical gradient-driven energy production is universal among all cellular life, going back to the last common ancestor, the method will apply to all organisms, although the effects and best conditions will depend on the electrical conductivity of their medium.
Maintaining ecosystem services in the face of accelerating global climate change will require methods that increase growth, survival, and resistance to escalating stress. These results indicate that the Biorock process is unique in accelerating settlement, growth, healing, branching, survival, and resistance to environmental stress. This allows marine organisms to be kept alive under conditions that would otherwise kill them, and enables entire complex ecosystems to be restored in a short period of time in places where there is no natural recovery (Figure 1). The Biorock electrolysis method, by stimulating the natural energy production mechanism, is the only ecological restoration method known that can maintain and restore marine ecosystems under conditions of accelerating global warming, sea level rise, ocean acidification, sedimentation, and excessive nutrient inputs, especially under severe stress where all other methods fail. It is urgent that the method should be optimized and applied on a large scale as soon as possible, especially in coral reefs, the ecosystem most threatened by global warming  , and in extending oyster reefs and salt marshes seaward to reduce coastal damage caused by global sea level rise.

Wind speeds and climate extremes are driven by atmosphere temperature and pressure differences, which are increasing due to global warming, because temperature differences between land and sea get greater with global warming.
Here is the latest global sea surface temperature and air temperature anomaly maps. The Arctic is exceptionally warm, and most of the North Atlantic is 2 degrees C or more above average, causing much more evaporation over the ocean that turns into snow in a northeaster, and dumps it on my sidewalk.
Also notice the hot water around Australia. The Great Barrier Reef will bleach for the third year in a row if this hot water does not go away very soon. The biggest patch of cool water, in the eastern equatorial Pacific, is the remains of a La Niña that failed to develop and is fast dissipating.
Coral reefs are already the first victims, we exceeded the global bleaching temperature tipping point threshold in the 1980s, there is now very little time left to save them.

Stephen Jay Gould (my advisor at Harvard), The Golden Rule, 1993 , phrases in brackets inserted for clarity.
“By what argument could we [humanity], arising just a geological microsecond ago, become responsible for the affairs of a world 4.5 billion years old, teeming with life that has been evolving and diversifying……Nature does not exist for us, had no idea we were coming, and doesn’t give a damn about us…..
We can surely destroy ourselves, and take many other species with us…..On geological scales our planet will take good care of itself and let time clear the impact of any human malfeasance [but it will take several million years]……
If we all treated others as we wish to be treated ourselves, then decency and stability would have to prevail. I suggest we execute such a pact with our planet.
She holds all the cards, and has immense power over us – so such a compact, which we desperately need but she does not at her timescale, would be a blessing for us and an indulgence for her.
We had better sign the papers while she is still willing to make a deal. If we treat her nicely she will keep us going for a while. If we scratch her, she will bleed, kick us out, bandage up, and go about her business at her own scale…..
The Earth is kinder than human agents in “the art of the deal”. She will uphold her end; we must now go and do likewise.”

Corals continued dying around the world in 2017 from global warming, pollution, and disease, and GCRA continued to show policymakers and the public the severity of the damage and to pioneer regenerative solutions. GCRA will accelerate its efforts in 2018.
GCRA’s Indonesia coral reef restoration projects continued to lead the world in 2017. Our Balinese partner, Yayasan Karang Lestari, recipient of the 2012 United Nations Equator Award for Community-Based Development, was selected for special honors at the 2017 World Ocean Day Event at the UN Oceans Conference for turning their village from the poorest in Bali to one of the most prosperous by restoring their coral reef. Last year, corals on Biorock reefs in Indonesia survived when severe bleaching killed almost all the corals around them, and Biorock reefs grew back a severely eroded Sulawesi beach in just a few months by growing corals and seagrasses in front of Pulau Gangga Dive Resort. Biorock Indonesia teams continued to manage around 300 Biorock reefs, start many new ones, and train new teams to start projects all across Indonesia. See 2017 Biorock Indonesia training workshop clips below:
Biorock coral restoration projects were maintained at several locations in the Panama Caribbean. One of the finest coral reefs left in the Caribbean, with exceptionally large ancient corals, was studied in the Guna Comarca (Indigenous Territories). Another reef with high live coral cover was found right in front of the Panama Canal breakwaters, and efforts are underway with local environmental groups to save this reef from being killed soon by dredging for a container port.
The first new Biorock reef restoration projects in Jamaica in 25 years were started near the last ones. A coral nursery growing elkhorn coral was established. This coral used to form huge forests at this site, but all vanished decades ago. The project is very small because of the tiny amount of coral now available to propagate, but will expand quickly as it grows rapidly. The best reef left in Jamaica was filmed, and efforts re-started with the local community to get it protected and managed locally.
New coral reef restoration projects were developed for early 2018 with local partners in Grenada, Mexico, Indonesia, Panama, Bahamas, and Vanuatu. These will incorporate new advances in Biorock Technology, and feature use of CCell wave energy devices to protect eroding shores and grow beaches back. See announcement.
GCRA researchers published a paper in the Journal of Animal Behavior showing electrical fields around Biorock structures inhibit sharks from biting but have no effect on other fishes. Available here. The tiny electrical field confuses sharks so they don’t bite. Biorock coral reef restoration projects can help protect people and sharks from harming each other.
Biorock oyster and saltmarsh restoration projects in cold waters continued at our toxic waste sites in New York City, and a short experiment was done to test applicability in San Francisco Bay.
Research projects were started with the University of Aalborg in Denmark, and the University of the Basque Country in Spain focusing on the chemistry, physics, and engineering properties of the materials produced by the Biorock process.
Tom Goreau spoke on large-scale community-managed marine ecosystem restoration at the United Nations Oceans Conference in New York, and at the United Nations Climate Change Conference in Bonn. His paper on the factors controlling the rate of CO2 drawdown to reverse climate change was published in the Proceedings of the UN Food and Agriculture Organization Global Conference on Soil Organic Carbon in Rome. He also participated in international conferences on agricultural regeneration in Mexico, on regenerative development to reverse climate change in London, and on re-greening of the Sinai Desert in the Netherlands.
GCRA filmed an interview by Tom Goreau with Professor Robert Kent Trench, the world’s top expert on coral symbiosis, looking at the oldest coral reef photographs from Belize and discussing the changes. Tom Goreau featured in two full-length documentary films that are now in final production stages for release in 2018. One film directed by Marcy Cravat will be on soil carbon and reversing climate change, the other by Andrew Nisker will be on environmental impacts of golf course chemicals. A new documentary was funded to start filming in 2018 on the historic GCRA Coral Reef Photograph Collection, the world’s largest from the 1940s, 1950s, and 1960s, and the long-term changes they document.
GCRA researchers looked at a major collection of nearly a thousand corals from the Great Barrier Reef, made 50 years ago in 1967, but packed away in a museum without ever being identified or studied, and is assisting getting the corals documented and identified, along with the major taxonomic collections of Caribbean corals.
GCRA proudly announces the GCRA Coral Classics Series, with the first volume to be posted in early 2018 being A STUDY OF THE BIOLOGY AND HISTOCHEMISTRY OF CORALS, the foundational work of coral biology and coral reef ecology. This masterpiece by Thomas F. Goreau, the world’s first diving marine scientist and founder of modern coral reef science, was his 1956 Yale University Ph.D. thesis. Although it is the essential starting point for all serious students of corals and coral reefs, it has long been unavailable. The GCRA publication includes all the original figures and photographic plates from the classic study of coral anatomy, ecology, and physiology available, newly re-edited individually for clarity.
Not 2 degrees, not 1.5 degrees, not even 1 degree!
That’s why the United Nations Framework Convention on Climate Change, where I will speak tomorrow about large-scale regeneration of marine ecosystems to reverse global climate change, is a death sentence for coral reefs as it now stands, because governments have chosen to sacrifice coral reefs, despite the scientific evidence that they are the most climatically vulnerable ecosystem!
The documents below show that the UNFCCC was fatally flawed from its conception, and needs to be strengthened if it is not to prevent global warming-caused extinction of coral reefs and flood low lands where billions of people now live.
TECHNICAL BRIEFING FOB INTERGOVERNMENTAL NEGOTIATING COMMITTEE MEETINGS UNITED NATIONS. NEW YORK. MAY 7 1992
MEMORANDUM: CAN WE AVOID ECOSYSTEM DAMAGE FROM CLIMATE CHANGE?
TO: INC NEGOTIATORS
FROM: Dr. Thomas J. Goreau, President, GCRA
1. IPCC projections for future climate change are based on assumed sensitivities of temperature and sea level to carbon dioxide increase that are 1O times less, and 1250 times less respectively, than have actually taken place in the past. The last time global temperatures were 1-2 degrees C above today’s values, sea level was 5-8 meters higher, compared to the 0.1 to 0.3 meters projected by IPCC. These observed changes imply that current projections may seriously underestimate potential long-term rises in sea level and temperature.
2. Coral reefs around the world are bleaching from heat shock stress and corals are increasingly dying as episodes increase in frequency and intensity. Bleaching took place after “hot spots”, regions of ocean temperature 1 degree C above normal, hit reef areas during the hottest months. Mass bleaching was unknown before the 1980s. Reefs which have escaped hot spots by luck are certain to be damaged if they continue. Major components of tropical marine biodiversity, fisheries, tourism, and shore protection are at serious risk from global warming.
3. Halting global warming requires stabilization of C02 concentrations in the atmosphere, not just stabilizing emissions. This requires both reduced supply of C02 to the atmosphere from fossil fuels and increased removal of C02 by protecting remaining forests and reforesting currently degraded areas. Simultaneous supply and demand-side measures are needed. Rapid global increase in biomass is essential because this is the only practical measure which can significantly reduce C02 concentrations within decades. Even drastic emissions reductions require over a century to have major impacts on C02 levels. Reforestation and increased energy efficiency together can affordably stabilize C02, providing an interim measure until non C02-producing energy sources replace fossil fuels.
4. Forest protection is not a sectoral issue. Boreal forests are the most efficient carbon sinks because they hold on to carbon for the longest in wood and soil. Tropical forests are inefficient, they hold on to carbon for a short time before returning it to the atmosphere. However, increased tropical forest cover is also critical because it is the most important ecosystem for reducing the atmospheric lifetime of C02 and the total heat each additional molecule adds to the atmosphere. Global warming will make all forests less efficient carbon sinks. Oceans are an extremely inefficient sink, unless they are dangerously polluted.
5. The Convention at present Is Inadequate to protect coral reefs from climate change. It requires stronger commitments to reduce atmospheric greenhouse gas concentrations. Global, long-term, wholistic thinking Is needed on all sides now before it is too late to save and restore reefs and forests.
