The Good, The Bad and The Ugly

Two news, one good and one bad. Then the ugly:

THE GOOD: NASA claims to have developed an innovative method called OMEGA (Offshore Membrane Enclosures for Growing Algae), that grows algae, cleans waste-water, captures carbon dioxide and ultimately generates biofuel without competing with agriculture for water, fertilizer or land.  Wow.
The system is made up of large flexible plastic tubes called photobioreactors. They float in seawater and contain freshwater algae growing in waste-water. These algae are among the fastest growing plants on Earth.  They use energy from the sun, carbon dioxide and nutrients from the waste-water to produce biomass that can be turned into biofuel and other valuable products such as fertilizer and animal food. In the process, the algae clean the waste-water by removing nutrients that would otherwise contribute to forming marine deadzones.Photo: NASA
The objective of this project is to investigate the technical feasibility of a unique floating algae cultivation system that could lead to commercial uses. Research by scientists and engineers has so far shown that OMEGA is an effective way to grow microalgae and treat waste-water on a small scale.
NASA is analyzing the OMEGA system as an alternative way to generate aviation fuels. Potential implications of replacing fossil fuels include reducing the release of green house gases, decreasing ocean acidification and enhancing national security.

OMEGA Project Accomplishments:
(NASA OMEGA project: Jan 2010 – May 2012)
    •    Demonstrated controlled microalgae growth on waste-water in floating PBRs.
    •    Operated 100, 200, 1,600, and 3,200-liter PBR systems for repeated algal growth cycles.
    •    Showed that forward osmosis could be potentially coupled with OMEGA to enhance both biomass production and waste-water treatment.
    •    Showed efficient uptake of CO2 using gas exchange column.
    •    Developed protocols for harvesting algae and controlling grazers.
    •    Determined impact of biofouling.

THE BAD: A team of researchers from the University of Queensland has studied how Ocean Acidification affects the settlement of baby corals onto a reef.  This important study found that the increase in acidity in the oceans has a dramatic effect on their ability to survive.  Christopher Doropoulos, lead author of the study, commented that “baby corals are initially found as swimming larvae before they choose their place to attach to the reef and settle for life, a critical step to their survival and the maintenance of coral reefs. […] The coral larvae normally have this amazing ability to settle on one particular type of rock-like seaweed called Titanoderma. This stony seaweed is a safe haven for young corals, yet we found that, as levels of ocean acidification increased, the coral larvae avoided this seaweed and started to settle absolutely anywhere.”

“Ocean acidification also changed the types of seaweeds available to the corals and had a damaging effect on their preferred species of Titanoderma,” said Mr Doropoulos.
“Our study identifies three major negative impacts of ocean acidification on baby corals. It reduces the number of corals settling, it disrupts their behavior so that they make unwise decisions, and reduces the availability of the most desirable substrate for their survival. This may have severe consequences for how coral reefs function and how they recover from major disturbances.”

Ocean Acidification and Education
Tuesday, May 01, 2012
By Daniel de la Calle

Inspired by our upcoming screenings for students this Thursday and Friday in the Southern Chilean town of Puerto Montt we want to post information for and about students and Ocean Acidification:

»Students from the Ridgeway School (Plymouth, UK) were commissioned by the European Project on Ocean Acidification (EPOCA) and the UK Plymouth Marine Laboratory to produce an animation film to explain the issue of Ocean Acidification to young people.  They talked to scientists, conducted their own research both at school and in the National Marine Aquarium and were involved in the whole process of animation.  The result was this 8 minute film that won the Royal Society of Chemistry's Bill Bryson Prize.


»Last month youngsters from Ivybridge Community College,UK, and from Brest, Brittany got together and exchanged ideas and oppinions on invasive non-native species and Ocean Acidification.  The event was supported by Marinexus, a cross-channel research and outreach project to bring together marine science and outreach in Devon and Brittany to raise awareness of marine ecosystems in the Western Channel and of their ability to cope with the effects of human activity.

»The classic Ocean Acidification experiment with vinegar and white chalkboard chalk carried out at the Reuben H. Fleet Science Center in San Diego, California. Easy to replicate in any school:


»Santa Monica High School’s "Car Team" students of Team Marine won First Place out of 35 high schools in the 2011-12 QuikSCience Challenge, a regional environmental science ocean stewardship competition. Since the beginning of the school year, “Car Team” students have worked to convert a 1971 red convertible Volkswagen Super Beetle into a 100 percent electric vehicle (short video). With their zero-emission car awaiting its final step (installation of the battery pack), the students’ “lesson plan on wheels” will soon be wrapped with the logos of all sponsors and showcased across Los Angeles County at schools and community events to promote cleaner alternative transportation. As part of their competition, they also went to Lincoln and John Adams Middle Schools to educate youth about the problems of and solutions to climate change and ocean acidification.
As part of the conversion process, the students have created a manual with pictures intended to help others repeat the process. Students have worked with local electric car experts, including Paul Pearson of Gas to Electric Conversions, as well as Samohi's automotive teacher Dan Cox, and City Hall's Rick Sikes to develop the manual.

»University of Miami grad student Rachel Heuer has received a National Science Foundation Graduate Research Fellowship to study how Gulf toadfish (Opsanus beta) might cope with Ocean Acidification.

 "Her initial findings indicate that toadfish exposed to elevated CO2 levels, relevant for the near future and current upwelling regions, lose increased amounts of base from the body through the intestine. This is problematic since toadfish and other marine fishes need to retain bases to help them cope with acidic environments. Heuer's preliminary findings suggest that this intestinal base loss negatively affects their overall pH balance and health.
"During my NSF Fellowship, I hope to build upon these findings by assessing the energetic cost and exploring the effects of long-term CO2 exposure in the Gulf toadfish. I am excited to utilize this fellowship to contribute to a rapidly expanding field of ocean acidification research," says Heuer."

»Finally, for those that have finished their studies and are looking for work the Imperial College London offers a 3 year Postdoc in Modelling Biodiversity Responses to Human Impact.  The main research objective is to develop a rigorous global model of how local biodiversity responds to human impacts, in order to support projections of how alternative socio-political scenarios will affect global and regional biodiversity. Biodiversity data will come from published comparisons of assemblage composition along gradients of threat intensity. You will develop and populate a database of precise measures of threat intensity corresponding to the diversity data, developing new measures from remote-sensed data as necessary; you will also develop a database to hold species=92 functional trait data. You will employ advanced statistical modelling tool, such as generalized additive mixed models, to relate diversity to threat intensity. The successful candidate will work closely with Professor Andy Purvis (the Principal Investigator).
You must have a PhD in Ecology or Environmental Science or have equivalent level of professional qualifications and experience.  For more details, click HERE

Protection
Monday, March 19, 2012
By Daniel de la Calle

»Could the protection of marine areas be counterproductive? That is what Professor Ray Hilborn, from the University of Washington's School of Aquatic and Fisheries Sciences, believes. Professor Hilborn stated in late February during an interview for an Australian radio station.  You can read the transcript HERE and listen to the interview HERE.
While some of his arguments are somewhat interesting I could not agree less with them.  Protecting land, lakes, rivers and seas is always a good idea and has proven to be visibly effective: beneficial. To claim that this will increase fish and seafood demand from parts of the world (China, Thailand or Brazil) where fishing and farming is not properly done just means some measures need to be taken about food imports.  The rest is demagogic.  The US, Australia or the EU could easily ban such imports, take measures, work with producing countries on production and quality control, impose sanctions.  To affirm that marine reserves do nothing other than appease people's consciences and deviate us from global problems like Ocean Acidification is first of all not true.  Since when is a good policy the one responsible for bad practices in other areas?  We could perfectly well be protecting marine areas while we finally began taking worldwide factual measures.  I simply cannot see how setting up good examples and leaving some parts of the world in peace from the stress we cause upon them is in any way detrimental.  Let's move the discussion to terra firma: would Professor Hilborn suggest to act in the same fashion in his country's National Parks? Should hunting and controlled farming be allowed in Yosemite and Yellowstone?  I think the problem for the nth time is that we persist in looking at the seas of the world with different eyes from the way we see land, that is why we continue using them as "magical" dumps and we are depleting them in the style hungry teenagers go through their parent's fridges some Saturday nights.

»The Center for Biological Diversity filed a formal notice of intent to sue the National Marine Fisheries Service this week "for failing to develop a recovery plan for two species of coral, elkhorn and staghorn, that live off the coast of Florida and the Caribbean.  Although these corals have been protected under the Endangered Species Act since 2006, the Fisheries Service still has not yet developed a crucial, and legally required, recovery plan to avoid extinction and secure their future survival."
Both elkhorn and staghorn corals were in fact the first species to be protected under the Endangered Species Act back in 2006 due to the threat of global warming and Ocean Acidification.  In a few decades they have declined by more than 95%. Photo: Elkhorn and Staghorn corals

»Mobile marine reserves as means for protection in the future.  This is the proposal conservationists brought forth at the annual meeting of the American Association for the Advancement of Science in Vancouver, Canada.  How would this work out?  The mobile marine reserves would use GPS tracking devices to follow endangered marine animals such as sharks, leatherback turtles or albatross and the areas with the highest populations would be temporarily closed down to trawlers and industrial fishermen.  As Professor Larry Crowder of Stanford University expressed at that meeting, "Less than 1% of the ocean is protected at this point, and these marine parks tend to be built around things that sit still like coral reefs and seamounts. But tracking studies show that many, many organisms - fish, marine mammals, sea turtles, seabirds and sharks - respond to oceanographic features that don't have a fixed point. These features are fronts and eddies that may move seasonally, from summer to winter, and from year to year based on oceanographic climate changes like El Nino or the Pacific Decadal Oscillation."
The idea is no doubt interesting; whether it is realistic or not depends more on national and international regulation, since the technology is already available.

»The Atlantic Ocean Alliance has launched a campaign to protect Antarctica's ocean through the world's largest network of marine reserves.  The Antarctic Ocean contains waters from the Indian, Atlantic and Pacific Oceans and for this reason some scientists do not consider it a separate ocean.  Although this part of the world is largely untouched and unexplored it faces several environmental problems derived from climate change, overfishing, ultraviolet radiation and Ocean Acidification.  The area the Atlantic Ocean Alliance wants to conserve is the Ross Sea.  The protection network would cover roughly 3.6 million square kilometers between Antarctica and New Zealand.  It is seen "as a first step towards establishing a comprehensive network of marine reserves and MPAs around Antarctica.” The proposal was presented to the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), a body made up of representatives from 24 nations and the European Union that is precisely focusing on protecting marine areas in the Antarctic this year.

Woke up today missing Jimmy McNulty, hence the title.  News, unstoppable, like rolling trains filled with sea adventures, awards, money, great videos and mahi mahi.  Who could possibly offer you more?:

MBARI (Monterey Bay Aquarium Research Institute) researchers started carrying out this past February a three month expedition along the Gulf of California, that 700 mile long finger of water between the peninsula of Baja California and mainland Mexico.  You can check on their website logbook for updates on their research, which involves no less than two vessels, over 25 ROV pilots, 60 scientists plus the ship's crew.  Since the scope of research is quite broad, the expedition has been divided into seven legs, each one lasting around ten days.  Leg number four will be about greenhouse gases in the deep sea.  It will be led by Peter Brewer (buscar) and the marine chemists present will study the behavior of methane and carbon dioxide in the high-pressure and low-temperature environment of the gulf's deep basins.  They are hoping that Brewer's work will help in the design of future experiments to test the effects  of Ocean Acidification on a variety of marine organisms.
Also, check this mesmerizing, soothing and informative video on jellyfish made by MBARI staff.  It won honorable mention in the National Science Foundation's 2011 International Science and Engineering Visualization Challenge.

University of Miami student Sean Bignami has received a $5,000 scholarship as winner of the Guy Harvey Scholarship Award. Mr. Bignami is a graduate student pursuing a Ph.D. at the Rosenstiel School of Marine & Atmospheric Science.  The focus of his study is how the changing chemistry of the marine waters as a result of Ocean Acidification might affect the early development of large marine fish.  His work uses mahi mahi and cobias as case studies.
He intends to devote much of his career to sharing the results of his research with decision-makers to ensure marine resources are managed effectively. He has also been teaching marine science to teachers and students, and for the last two years has worked with the “Science Made Sensible” outreach program, an effort that pairs Miami graduate students in science, math and engineering disciplines with middle school science teachers to provide students with more hands-on learning experiences.
"Communication is often not the strongest of a scientist's skill set, at least not when considering the general public's need for information to be delivered in a simple way that highlights its application to everyday life," Bignami wrote in his scholarship application. "Reaching the public at a young age may be the most important way to instill love and appreciation for the ocean and the services it provides."

This news piece is not so new.  A team of 19 scientists, using sensors developed at Scripps Institution of Oceanography at UC San Diego reported this past January results about the broadest worldwide Ocean Acidification study to date.  They measured acidity in 15 ocean locations, from the Antarctic to the temperate and tropical seawater and results were very different from one place to the other.  While in places like the Line Islands of the South Pacific and Antarctica the range of pH variance is limited, in sections of the California coast subject to upwelling pH fluctuations are intense.  In some of the study areas the decrease in seawater pH deriving from CO2 emissions was still within bounds of natural pH fluctuation, but other areas already experience daily acidity levels expected to only be seen at the end of the century.
The study was made possible because all sensors were designed by Todd Martz, marine chemistry researcher at Scripps, so he "was in a unique position to assimilate a number of datasets, collected independently by researchers who otherwise would not have been in communication with each other.  Each time someone deployed a sensor they would send me the data, and eventually it became clear that a synthesis should be done to cross-compare this diverse collection of measurements," he said.  That was when Gretchen E. Hofmann, an eco-physiologist and professor in UCSB's Department of Ecology, Evolution & Marine Biology, worked with Mr. Martz to put together the research team to create that synthesis.
The authors noted that they only worked with information about coastal surface oceans, so more study is needed in deeper ocean regions further off the coast.

In South America This Fall: In April!

Today we want to briefly share with you our plans for A Sea Change during the upcoming months.  During the last few months last year, we had been discussing our possible presence during the RIO+20 summit this coming June.  We kept receiving mixed signals: encouraging, hopeful news together with worried comments about the role given to the oceans at the summit, the sudden change of schedule (it was initially going to coincide with Britain's Queen Elizabeth's crowning anniversary…), about the official agenda and the way things were being organized.  In the end both Barbara and Sven thought it might be important for Niijii Films to travel back to Brazil with the hope of creating more focused buzz around ocean acidification.  It was their view that with credentials, we could enter the conference itself and share an ocean acidification media package that would contribute information to ongoing discussion about ocean health in  Rio de Janeiro.  We are still working on the specific plan for the days of Rio+20, so your suggestions and ideas are more than welcome.  Should we organize our own event during the summit? Of what type? Would it make an impact to distribute copies of the documentary amongst the delegations? Do we need to be present at all the major meetings? Which are a most critical? Should I pack my own lunch or buy it there? Please email me at aseachangedocumentary@gmail.com if you plan to attend the conference and would like to meet, or if you have some words of advice or experience for me, I will be delighted and grateful.

We have also begun to schedule some work both in Peru and Chile for late April and early May.  We are aiming for a couple of screenings in Peru followed by three in Chile and hope to do as many interviews as possible, get the media interested and willing to inform Chileans and Peruvians; the same type of effort we displayed in Brazil and Colombia during 2010 and 2011.  Again, if you have any recommendations of universities or institutions we should contact for the screenings, or know which are the most crucial newspapers and television channels to deliver our message about Ocean Acidification through, please write us at aseachangedocumentary@gmail.com.

It has been over three years since the film premiered in the States, five since we began filming, but the story continues to resonate with force.  Maybe because A Sea Change came out before most people had heard about Ocean Acidification, because the scientific community keeps revealing the detrimental consequences of higher acidity in the ocean or because of the film's deeper message about our legacy for future generations, the truth is that A Sea Change will be very much alive in 2012.

¤Marine Spacial Planning presents a rational approach to ocean management.  The system tries to "allocate space in the ocean allowing compatible uses to coexist, separating incompatible ones, all while protecting the environment".  This video presentation with Philippe Cousteau explains things in more detail:

"The ocean economy in the USA is larger than the entire farm economy and employs almost twice as many people."

¤PDF by the National Marine Sanctuaries and NOAA on West Coast Sanctuaries and an Ocean Acidification Plan.

¤We post (almost) all videos that have to do with Ocean Acidification.  THIS ONE HERE comes from Tufts' University Environmental Biology class and it was done by Valerie Cleland, Anne Elise Stratton, Erica Rigby, Zobella Vinik. Artsy.

¤Interesting study funded by The Nature Conservancy (PDF). It is titled "Detecting regional anthropogenic trends in ocean acidification against natural variability" and quoting the authors it shows "that the current anthropogenic trend in ocean acidification already exceeds the level of natural variability by up to 30 times on regional scales. Furthermore, it is demonstrated that the current rates of ocean acidification at monitoring sites in the Atlantic and Pacific oceans exceed those experienced during the last glacial termination by two orders of magnitude."

¤Scientists from the Instituto de Ciencias del Mar in Barcelona have identified the molecular mechanism that links the increase of water temperature to the inhibition of aromatase.  Aromatase is the enzyme responsible for transforming androgens into estrogens, and estrogens are essential in the formation of ovaries in all non mammal vertebrates. So under high temperatures during the larval and juvenile periods of sea bass this epigenetic environmental factor "overwrites" DNA information and turns all initially female sea bass into males.


... which indirectly has to do with what I see as the irrevocable responsibility derived from knowledge, the one that raises the profound moral question of entitlement.  We often discuss our choices around the planet and the need for preservation and protection in view of our future survival as a specie. We cry about deforestation in the Amazon jungle imagining all the hypothetical drugs that would have been extracted from plans, fight against overfishing in fear of depletion of a food source, protect air quality with our children's lungs in mind.  This barely raises our status in the animal kingdom to that of a sophisticated predator, exclusively focused like the rest on self preservation, lately becoming a plague to all life matter. I am completely certain that the women and men of the next era, if we do not cause our own fall and hope to deservedly call ourselves "evolved" will fully understand the position of responsibility for our actions, acting as we do now on a planetary scale.  Those people of the future will obviously continue to plant, harvest, kill to eat, or for protection, will still want a comfortable and happy life, but they will do it all responsibly, placing first that question of entitlement.

My best buddy jokes that the world is like a public toilet: we all want to walk into the same kind of place.  The way each one of us leaves it behind is unfortunately another story.


Saint Nicholas Post

 As advanced celebration of Saint Nicholas the Wonderworker tomorrow, here are a few links, photos, videos and news for you all, stuffed inside the shoes you are putting out tonight:

    A team of scientists at Santa Cruz's University of California have spent the past three years studying the submarine springs at Puerto Morelos, Mexico.  The springs offer a preview of sorts of the fate of coral reef ecosystems in a less basic (damaged by Ocean Acidification) marine environment.  The submarine springs, known as "ojos", are common along the eastern coast of the Yucatán Peninsula.  For thousands of years limestone "karst" landforms near the coast have featured underground drainage systems that discharge brackish water at the ojos.  The discharged water has lower pH than the surrounding seawater.  Professor Adina Paytan and the rest of the team monitored ten of those "eyes" (ojos) and conducted ecological surveys around each site.  "This study has some good news and some bad news for corals," said Paytan, coauthor of a paper published last november in the journal Coral Reefs,  "the good news is that some species of corals are able to calcify and grow at very low pH.  The bad news is that these are not the ones that build the framework of the coral reefs.  So if this is an indication of what will happen with future ocean acidification, the reefs will not be as we know them today."

    Following up on such efforts as the World Seed Bank, Australia's Taronga Western Plains Zoo has started developing a "frozen zoo", a bank of genetic material from endangered species.  Some frozen sperm and IVF embryonic cells from two coral species present in the Great Barrier Reef were flown this past November to the New South Wales zoo.  The vials, stored now in liquid nitrogen, contain enough material to produce more than a million new corals even hundreds of years from now.  Those new corals could be used in some future re-population or to increase the genetic diversity of particular reefs.  The work was carried out by the zoo's manager of research and conservation programs, Dr Rebecca Spindler, and by Dr Mary Hagedorn, a world expert in coral IVF at the Smithsonian Institution.  They worked with two common staghorn species (Acropora millepora and Acropora tenuis), but Dr Hagedorn understands they now "need to sit with Australian coral scientists and ask which are the most important species for Australia [to store]".

    Northwest oyster die-offs made the news in newspapers, television and the internet last month.  THIS is a good piece by Elizabeth Grossman for Yale Environment 360 on the hatcheries and the problems this $73 million a year industry has had to endure since 2006.  The particular water conditions of this region, in which colder, more acidic waters surge from the bottom of the ocean, has already made it very difficult, at times impossible, for oyster larvae to grow.  The article has interesting quotes by NOAA's Dick Feely, George Waldbusser from Oregon State University and Benoit Eudeline, chief scientist at the Taylor Shellfish Hatchery.

    Virginia's oyster industry is taking very seriously the news about Pacific Northwest farms being affected by Ocean Acidification and is trying to take proactive monitoring measures and lessons learned in other areas for the more-than-probable future.  Although cases of damage from acidification have only been noticed in Maine, the Atlantic coast could begin to suffer from the same oyster larvae hatching problems seen West.

    A large ceramic coral reef is awaiting those who visit the American Association for the Advancement of Science in Washington.  The 10 by 15 feet piece was created by artist Courtney Mattison with the title "Our Changing Seas: A Coral Reef Story".  In the words of Ms. Mattison it "combines marine conservation science and policy, fine art and social sciences".  The large mural work is part of a group exhibition called "Beneath the Surface: Rediscovering a World Worth Conserving".
More info from the NOAA Coral Reef Conservation Program HERE.

    Scientists at UCSB's Marine Science Institute recently confirmed the critical role algae-clearing fish have in coral growth and recovery.  At Moorea Coral Reef in French Polynesia the researchers discovered that the region's herbivorous fish clear the way for coral growth by eating algae from around the reef.
A combination of a series of cyclones and the raise in numbers of crown-of-thornes sea stars had brought the previous 40-45% outer reef coral coverage (which is significantly high) to almost zero, but the corals are beginning to make a comeback.  Although algae usually take over a cleared area, fish prevented them from reaching a level of coverage that kept baby corals from growing.  MSI scientists believe more effort should be put in the future into preserving fringe reefs, where algae-consuming fish grow up, in order to have a healthy population of adult fish in the future.

    A year or two ago we already wrote about this: Mussel shells are perfect recoding devices into which scientists can examine water acidity and other significant data.  Dr. Cathy Pfister from the University of Chicago and her colleagues have been taking samples from 1,000 year old middens from the Makah Nation in Washington State, comparing them with shells from the 1970s and 2000s and measured the changes.  

The conclusion is that they are even greater than would be expected from the process of Ocean Acidification, local upwelling or the changes in nitrate and phosphate.

     The University of New Hampshire will benefit from the more than $1.7 million federal funding recently awarded by NOAA to NEARCOOS, the Northeastern Regional Association of Coastal Ocean Observing Systems.  The money will go to the University of Maine, the Gulf of Maine Research Institute, the Universities of Maine, Massachusetts, Rhode Island and Connecticut and the Bedford Institute of Oceanography, in Nova Scotia as well.  The University of New Hampshire plans to use these moneys to support a wave buoy implemented with instruments to continue measuring Ocean Acidification at Great Bay.

The Hook that Caught the Fish that Saves the Corals that Inspired the Artist
Sunday, November 27, 2011

By Daniel de la Calle

 

Here are a few Ocean and Ocean Acidification news bits found while surfing the web over the past week.  I hope some are news to you:

    How long has man been catching fish from the open ocean? 42,000 years at the very least. Archeologists from the Australian National University in Canberra have found two broken fish hooks made from shells amongst 38,000 fish bones in a cave in East Timor.  It is not known how the fish were caught, but researchers speculate that it was done from boats or rafts using either nets or fiber lines with hooks.  Published three days ago in the journal SCIENCE. READ IT HERE.


The fishing hooks. Scale is in millimeters.

  •According a study in the current issue of Proceedings of the Royal Society B: Biological Sciences by researchers led by David Bellwood from James Cook University in Queensland, the depletion of large fish due to overfishing can lead to a reef containing only small fish that cannot perform crucial cleaning tasks for the development and sprouting of new colonies.  Research focused on parrotfish across 18 locations from the western Indian and Central Pacific Oceans and concluded that large parrotfish are the real efficient pruners and cleaners of vast reef systems thanks to their jaw size.

In their absence, small fish can only do their light grazing activities that are known as "dusting".  An increase in the number of small fish means the dusting is overdone while the mowing and weeding is being neglected.  Once again, a lesson on moderation and the fragility of ecological balance.  Read more HERE or HERE.

    Colleen Flanigan, an environmental artist and metallurgist from the US is going to use Biorock (a trademark technology developed in the 1970s that runs a low-voltage electric current through metal in saltwater, causing the accumulation of limestone) to grow a coral colony on a metal sculpture.  The sculpture was built in Cancún last June; it has a 15 by 6 feet sinuous design inspired by the DNA double helix and is planned to be lowered via crane into the shallow waters of MUSA, the underwater museum off Cancún I wrote about last year, the one with the 400 life-size submerged sculptures by Jason deCaires Taylor.  The electrolysis taking place with Biorock lowers the acidity of water and could one day make possible small "artificial" niches of corals in a marine environment that might otherwise be hostile to polyps.

    Going much farther back than the aforementioned 42,000 years, to some 250 million ago, about 95% of our planet's marine life and some 70% of all terrestrial species vanished forever as wildfires covered the planet, oceans acidified and temperatures soared.  A research team led by Shu-Zhong Shen, member of China's Nanjing Institute of Geology and Paleontology believes evidence points to a "runaway greenhouse event".  A study published last week on Science gives the most detailed picture yet on how the Permian mass extinction unfolded.  Our current problem comes from fossil fuel burnings, while during the Permian period the culprits were volcanoes releasing massive amounts of CO2 and methane.  Geological and also fossil records point to several "kill mechanisms", such as fires, acidification, loss of oxygen in the oceans and even hypercapnia (too much CO2 build up in organisms, causing death).  The world's climate at the end of the Permian changed "from basically like today, where you had hot tropics and cooler polar regions, to a world in which everything was a tropics", says Charles Henderson, of the University of Calgary.  This catastrophe did not happen overnight, though. It took thousands of years to die out and the bulk of the extinctions most probably occurred over a 20,000 year period.  Link to an article on the VANCOUVER SUN covering this information.

    Monterey Bay Aquarium Research Institute scientists have launched a sophisticated, unique tool to study the effects of Ocean Acidification on deep-sea animals in their native habitat, using free-flowing water.  The idea behind Free-Ocean Carbon Enrichment (FOCE) is to create a test area on the seafloor where seawater pH can be controlled.  Small animals can be placed in the test chamber and their behavior and physiological responses monitored.

    Two papers recently published in Global Change Biology by scientists from Australia, the US and France provide an interesting look at how the threat of Ocean Acidification to reefs vary from one to another.
"Overall, CO2 enrichment and ocean acidification is bad news for coral reefs", says Dr. Ken Anthony, Research Team Leader for the Climate Change and Ocean Acidification team at the Australian Institute of Marine Science.  "But some reef areas take up more CO2 than they produce (through photosynthesis), which can lower the vulnerability of neighboring reef areas to ocean acidification.  On the other hand, reef areas with greater coral cover produce more CO2 than they consume (through calcification and respiration) and that adds locally to the ocean acidification threat".  Dr Joanie Kleypas of the National Center for Atmospheric Research believes that "If we can start to understand which areas of large reef systems such as the Great Barrier Reef can counteract pH changes locally and which areas cannot, then we are better able to assess the relative risks of ocean acidification".
"Reef managers have been faced with the problem of ocean acidification as a uniform threat affecting all reef areas equally.  These new studies are a first step to help reef managers understand how some areas might in fact lower the impact of ocean acidification in neighboring areas, whereas others will further acidify themselves.  Seagrass beds, for example, can significantly reduce CO2 levels in the water, providing more favorable chemical conditions for neighboring reefs", says Dr Anthony.  Continue reading HERE.

    I recently saw an advertising piece about the use of biodegradable bags and plastic wrappings on sailing boats.  Sailors around the world should embrace the idea and commit to only using compostable and biodegradable bags, leading an example and modestly fighting the alarming presence of plastics in the oceans.  The particular brand is called BioBag, and HERE is the page where you can read more about the benefits of using such products.

    David Shiffman, a PhD Student and research assistant at the RJ Dunlap Marine Conservation Program asked for our vote in the 2011 Blogging Scholarship (which provides $10,000 towards education and research expenses) finals.  I already voted for him and his shark conservation blog HERE.  If you want to vote too just remember that it is the bubble next to "David Shiffman: Southern Fried Science".

    Two or three blog posts ago I wrote about insular dwarfism and this week I have some news about animals diminishing in size: recent studies indicate that climate change might be shrinking numerous plant and animal species.   David Bickford, from the National University of Singapore believes ectotherms (cold-blooded animals like toads, turtles and snakes that rely on environmental heat sources) are changing a lot.  The study draws information from fossil records as well as "comparative studies and research implicating anthropogenic climate change over the last hundred years".  For example, fossils from a warming phase during the Palaeocene-Eocene Thermal Maximum indicate that burrowing invertebrates like beetles, bees and ants shrank in size by up to 75%.  In the seas, each degree of warming has been shown to decrease the size of fish by up to 22%, but the biggest threat to marine life could be the reduced growth rates of phytoplankton in response to acidification, which "could negatively affect all ocean life because it forms the basis of the marine food web", says Bickford.

    Researchers in Spain are using posidonia oceanica seagrass meadows to track the evolution of heavy metal pollution in Mediterranean waters all the way back to 4,500 years ago.

The first heavy metal residue is found in the strata going 2,800 years back, coinciding with the first mining and metal work by Romans and Greeks.  During the last 1,200 years the presence of metals has increased gradually, but it was within the last 350, since the beginning of the industrial revolution, that the levels began to skyrocket, with a significant increase in the presence of lead, zinc and arsenic.  These threatened seagrass beds can be invaluable to research, but they more importantly serve as a great filter and storer of heavy metals along the Mediterranean shoreline.
As a footnote, the posidonia meadows around the coast of the island of Ibiza are over 5 miles long and are believed by some to be the biggest and eldest living organism, continually growing for over 100,000 years.

    A new study by a group of European scientists led by Michael T. Burrows, from the Scottish Marine Institute, reveals that, although ocean temperatures are increasing at a slower rate than in the atmosphere, its progress and effects on sea life is quite similar.  Spring keeps coming two days earlier every year and regional temperatures are traveling North and South from the equator at an average speed of 27 kilometers per decade.  Also, the rate of warming seen by the scientists was greatest in equatorial oceans, which is also where biodiversity is currently highest, the analysis shows.
Species are having to either migrate to keep living within the same temperatures or, in some cases, modify their reproductive times.  But these options are not available for all animals.  Arctic species cannot migrate to colder regions and in places like the Mediterranean, where the sea is enclosed between Europe and Africa, a migration North is not possible.  Carlos Duarte, research scientist for the Consejo Superior de Investivaciones Científicas in Spain concludes: "when the speed of climate change is faster than the speed organisms can disperse or when there are physical barriers that make dispersion impossible species can only adapt or become extinct."
