1 In less than two weeks our good friend and Associate Producer Ben Kalina will be premiering his new documentary SHORED UP at the Monclair Film Festival. We are all equally proud and eager to watch the final result of over three years of work and dedication.
SHORE UP:
"Our beaches and coastline are a national treasure, a shared resource, a beacon of sanity in a world of constant change…and they’re disappearing in front of us.
Shored Up is a documentary that asks tough questions about our coastal communities and our relationship to the land. What will a rising sea do to our homes, our businesses, and the survival of our communities? Can we afford to pile enough sand on our shores to keep the ocean at bay? In Long Beach Island, New Jersey and the Outer Banks of North Carolina, surfers, politicians, scientists and residents are racing to answer these questions.  Beach engineering has been our only approach so far, but is there something else out there to be explored?  Our development of the coastlines put us in a tough predicament, and it’s time to start looking for solutions.

2 UCSB professor Debora Iglesias-Rodríguez and postdoctoral researcher Bethan Jones have discovered a line of marine organisms that in fact increase their calcification in waters with dropping pH levels. In the new study published by PloS ONE and funded by the European Project on Ocean Acidification they found that the unicellular marine coccolithophore Emiliania huxleyi still manages to develop shells when exposed to waters with high CO2 levels.

3 A new study by University of Miami Rosenstiel School of Marine and Atmospheric Science researchers focuses on the effects of Ocean Acidification on cobia fish larvae.  These large tropical fish are highly mobile as they mature and constitute a popular species among recreational anglers.  After exposing the larvae to different levels of CO2 they discovered remarkable resistance consistency in growth, development and activity under probable end-of-the-century pH scenarios.  The study also showed a significant change in otolith ("calcium carbonate structures within the fish's inner ear that are used for hearing and balance") size, up to a 58% increase in mass.  Photo: Cod Otoliths
When tested in a mathematical model of otolith function, the result showed an increase in hearing sensitivity and up to a 50% increase in hearing range.
The study is the first to report impacts of ocean acidification on a large, pelagic tropical fish species.
"Increased hearing sensitivity could improve a fish's ability to use sound for navigation, predator avoidance, and communication. However, it could also increase their sensitivity to common background noises, which may disrupt the detection of more useful auditory information," says  University of Miami researcher Sean Bigmani.

6 The Ocean Cleanup Array is an innovative prototype designed to palliate one of the oceans' saddest problems: plastic pollution of the world's waters.  This design by aerospace engineering student Boyant Slat looks like a giant vacuum cleaner equipped with floating arms to direct plastic trash along the water surface to a central filtrating structure. The Ocean Cleanup Array project claims to be capable of collecting seven million tons of plastic a year with the use of solar and tidal power to run this vessel nonstop around the 5 ocean plastic gyres.

How much is too much?  When does a stream of information flow over and one more entry, article, news piece or documentary simply becomes redundant, numbing white noise, counterproductive annoyance? Searching online today, the 12th of April of 2013, for the term Ocean Acidification brings up 1.900.000 pages.  Little compared to Climate Change's 73.600.000, that's true, but when it comes down to the repercussion either figure is having in our fight against environmental threats it seems strength does not exactly lie in numbers after all. Could be we just need to reach the 1.420.000.000 behind Oil or the 2.990.000.000 coming with Money.  But we needn't despair yet, Love does still shines above all this with over 7.560.000.000 entries.*

"A melt of Greenland's ice is washing large amounts of the nutrient iron into the Atlantic Ocean where it might aid marine life in a rare positive side-effect of climate change, a study showed on Sunday.
Greenland's thaw, which is raising world sea levels, is also adding about 300,000 tonnes of iron a year to the North Atlantic, based on projections from the muddy melt water of three glaciers in the southwest, it said.

"We suggest that glacial runoff serves as a significant source of bio-available iron to surrounding coastal oceans," the scientists, mainly at the U.S. Woods Hole Oceanographic Institution (WHOI), wrote in the journal Nature Geoscience.
"We would expect this glacial contribution of iron to the North Atlantic Ocean to continue to increase under future warming scenarios," they added.
The findings show that "as glaciers and ice sheets melt there may be other effects than just increased sea level," said Maya Bhatia, who was leader of the study at WHOI and the Massachusetts Institute of Technology.

This is because the byssal threads become weaker and lose their ability to stretch as far."

According to Melissa Pespeni, evolutionary biologist at the University of Indiana, sea urchin larvae studied in her lab under a high CO2 environment showed few visible changes in growth and development, but some noticeable alterations in the abundance of certain genes.  The changed genes are involved in promoting growth, producing minerals and keeping pH within a range that's tolerable to them.
"If any organism were able to adapt and evolve, it would be the sea urchins, because they live in an environment where they're experiencing daily changes in pH," says Pepsini.
The urchins are very long-lived and have more genetic variability than any other species — including humans, she added. Consequently, the urchins have a broad arsenal for responding to changes in their environment.

≈≈≈≈Crabs, crabs, crabs. For some reason three studies about crabs and Ocean Acidification showed up in the news over the last few days:
The first one is about the "effects of Ocean Acidification on Juvenile Red King Crab and Tanner Crab Growth, Condition, Calcification and Survival".
"At the end of the experiment, calcium concentration was measured in each crab and the dry mass and condition index of each crab were determined. Ocean acidification did not affect the calcium content of red king crab but did decrease the condition index, while it had the opposite effect on Tanner crabs, decreasing calcium content but leaving the condition index unchanged. This suggests that red king crab may be able to maintain calcification rates, but at a high energetic cost. The decrease in survival and growth of each species is likely to have a serious negative effect on their populations in the absence of evolutionary adaptation or acclimatization over the coming decades."

Finally, the third one is about research published back in 2009 in the journal Geology by Justin Baker Ries (marine geologist at the University of North Carolina's Aquarium Research Center) and coauthored with Anne Cohen and Daniel McCorkle indicates that "higher levels of carbon in the ocean are causing oysters to grow slower, and their predators -such as blue crabs- to grow faster".  The article points out that "Over the next 75 to 100 years, ocean acidification could supersize blue crabs, which may then eat more oysters and other organisms and possibly throw the food chain of the nation’s largest estuary [Chesapeake Bay] out of whack."

We cannot let the month end and watch the season slowly fade out without a postful of links, videos, news and photos on Ocean Acidification:

»The Oceanography Laboratory at Villefranche-sur-Mer (France) is deploying nine "mesocosms" (52 m3) over a 30 days period in order to cover the range of pCO2 anticipated for the end of the present century.  These "mesocosms" are 15 meter deep plastic tubes closed at the bottom to collect organic matter and open at the top to remain in contact with the atmosphere.  25 researchers from six European countries are taking part in the tests, the second of their kind in the Mediterranean.  While the first experiment, conducted in June/July 2012 in Corsica, was dedicated to the assessment of ocean acidification effects during the summer oligotrophic period, this second one will take place during the winter-spring phytoplanktonic bloom.  Here is a "France 3" news piece on the story:

»Ocean Acidification may affect the Great Lakes in the same was it is altering the oceans, according to modeling the study of carbon cycles by Galen McKinley, Professor of Atmospheric and Oceanic Sciences at the University of Wisconsin.  It is clear this is a more complex environment, already severely affected by runoff from cities and agriculture and infested with invasive zebra and quagga mussels that absorb large amounts of calcium carbonate to build their shells.
“One potential area where we might get helped out with is impacts to quagga and zebra mussels,” says McKinley.  “Evidence shows they do not like the lower pH.”
But nobody can guess the outcome of this mix of pollution, Acidification and invasive species until some research is done. “Right now we don’t have enough consistent and detailed measurements to accurately capture what the pH level even is and if it is permanently changing,” says McKinley.

»"Ocean acidification and nitrous oxide"
By Michael Beman, University of California, Merced
"Human activities have fundamentally altered the chemistry of the atmosphere and ocean, ultimately pushing our planet into a new geological period known as the ‘Anthropocene.’ While human-driven increases in atmospheric carbon dioxide (CO2) concentrations—and their strong connection with climate change—are well-known, atmospheric nitrous oxide (N2O) concentrations have increased in parallel with CO2. N2O is both a strong greenhouse gas and the dominant destroyer of stratospheric ozone; the steady increase in N2O concentrations is driven primarily by agricultural fertilization, yet N2O is produced by multiple microbial groups that interact in complicated ways, and that may respond to other forms of environmental change. At the same time, climate change is not the only effect of elevated CO2: 25-33% of human-generated CO2 dissolves in the ocean, where it forms a weak acid and reduces ocean pH—a process known as ‘ocean acidification.’ pH is fundamental for ocean chemistry and ocean organisms, and changes in dissolved nutrients, metals, and forms of inorganic carbon are an expected consequence of future ocean acidification. Ocean pH is projected to decline by 0.3-0.4 units by the end of the century, producing wide-ranging effects that include reduced calcification in corals, shellfish, and phytoplankton; altered physiology in fish and other animals; and changes in ocean biogeochemical cycles. In this overview talk, I will present the drivers behind ocean acidification and increased N2O, the underlying dynamics of these changes, their projected effects, and their ultimate interactions."

In order to monitor the evolution of these changes, seven oceanographic surveys were carried out over six months (November 2011-April 2012) from the beginning of the eruptive stage to the post-eruptive phase. Here, we present dramatic changes in the water column chemistry including large decreases in pH, striking effects on the carbonate system, decreases in the oxygen concentrations and enrichment of Fe(II) and nutrients.

As well as being home to everything from whelks to whale sharks, the oceans offer a range of critical services, including acting as a source of food and regulating the atmosphere.
In particular, the oceans are also vital as sponges for green house gases, taking carbon dioxide out of the atmosphere through two processes - dissolving straight into the water column and also through photosynthesis by phytoplankton.
Today, the oceans soak up around one third of all of human carbon emissions

≈≈≈≈"Climate Change and Ocean Acidification", as delivered on the Senate floor by Senator Sheldon Whitehouse:
"Wednesday, December 12, 2012
Mr. WHITEHOUSE. Mr. President, there are many signs of the fundamental, measurable changes we are causing in the Earth's climate, mainly through our large-scale emission of carbon dioxide from fossil fuels. These are irreversible changes, at least in the short run, so we should take them very seriously.
Over the last 250 years, the global annual average concentration of carbon dioxide in the atmosphere has increased from 280 parts per million to 390 parts per million. That is a 30-percent increase. We have recent direct measurements that the carbon dioxide concentration increased by 15 percent since 1980 when it was 339. In 1980 it was 339 and now it is 390. That is just a dozen years in which the concentration of CO
2 in our atmosphere has increased by more than 50 parts per million. Fifty parts per million is a big shift if one is not aware of the scales we are talking about here. For 8,000 centuries--800,000 years--longer than homo sapiens have existed on the face of the Earth, we can measure that the carbon concentration in the atmosphere has fluctuated between 170 and 300 parts per million. A total range of 130 parts per million has been the total range for 8,000 centuries. We are now outside of that range up to 390, and we have moved 50 points since 1980, in a number of decades. So the consequences are going to be profound, and perhaps no consequence of that carbon pollution will be as profound as the increasing acidification of the world's oceans.
Science, of course, has known since the Civil War era, and most of us understand, that excess carbon dioxide in the atmosphere creates a warmer atmosphere known as the greenhouse effect. There is nothing new about that. But not all of the carbon dioxide emitted by human activity--by our use of fossil fuels--stays in the atmosphere. Carbon dioxide is soluble in water and the oceans cover 70 percent of the Earth. Where the atmosphere is in contact with the oceans, a portion of the carbon dioxide in the atmosphere dissolves into the oceans, reacts with the sea water to form carbonic acid and increases the overall acidity of the oceans.
There is sometimes quarrel and debate about complex modeling of climate and atmospheric projections, but evidence of ocean acidification is simple to measure and understand. Indeed, even the small noisy chorus of climate change deniers and corporate polluters is noticeably quiet on the issue of ocean acidification because they simply cannot explain away the facts.
National Oceanic and Atmospheric Administration scientists gauge that over the past 200 years, hundreds of billions of tons of carbon dioxide have been absorbed into the oceans. NASA, which is able to put, for instance, a man on the Moon and a Rover on Mars and has reasonably good scientists working there who can accomplish those achievements, reports that:
“The amount of carbon dioxide absorbed by the upper layer of the oceans is increasing by about 2 billion tons per year.”
NOAA scientists say the oceans are taking up about 1 million tons of carbon dioxide per hour. So in more or less the time my remarks are concluded, the equivalent of more than the weight of the Washington Monument of carbon will have been dumped into our oceans. All of the extra carbon dioxide humans have pumped into the oceans has caused the global pH of the upper ocean water to change--a nearly 30-percent increase in the acidity of the oceans.
As my colleagues can see, the curve is not only moving upward but is steepening. Where is it headed? By the end of this century, it is projected we will have a 160-percent rise in ocean acidity. As we can see, not only are the oceans becoming more acidic, but they are becoming more acidic at a very rapid pace. The rate of change in ocean acidity is already thought to be faster than at any time in the past 50 million years.
I talk, when I give this weekly speech from time to time, about the 800,000 years our planet has had a carbon dioxide concentration between 170 and 300 parts per million and how long a time period that is compared to say humankind having the mastery of fire, humankind having engaged in agriculture, humankind even existing as homo sapiens. It is longer than all of those things. But that is just measuring in the hundreds of thousands of years. We are talking about a rate of increased carbon concentration and ocean acidity climbing faster than at any time in the past 50 million years.
What does that mean? Well, a paper published in the journal Science, which is a mainstream, non-crank publication, earlier this year concluded that the current rate of carbon dioxide emission could drive chemical changes in our oceans that are unparalleled in at least the last 300 million years. We are back into geologic time now since we saw that kind of an effect. The authors warn that we may be “entering an unknown territory of marine ecosystem change.” Well, when our range of review is in the hundreds of millions of years and the authors are talking about entering unknown territory, that is really saying something.
Here is what Dr. Peter Brewer, the senior scientist at the Monterey Bay Aquarium Research Institute, has to say. Let me quote him:
“The outcome is very clear that we are in uncharted territory in the entire span of Earth history. The primary cause of this is simply the rate of CO2 change; we are changing Earth far, far faster than any recorded geologic shift ever.”
Repeat: “We are changing Earth far, far faster than any recorded geologic shift ever.”
What does this mean for marine life? Well, as the pH of sea water drops, so does the saturation of calcium carbonate, which is the compound found in the sea water that aquatic animals use for the construction of their shells and of their skeletons. Some sea creatures absorb calcium carbonate directly from the water; others ingest it as food and then through their bodies it works out to build their shells. At lower saturations of calcium carbonate, calcium carbonate is not as available to these species, and it becomes more difficult for them to make their shells; species such as oysters, crabs, lobsters, corals, and the plankton that comprises the very base of the oceanic food web. We have seen this happen in real life already with the disaster that befell the Pacific Northwest oyster hatcheries when acidic water came in and killed off all the juveniles that were being grown.
Over 1 billion people on this planet rely on marine protein as their primary source of protein, and then, of course, there are the countless jobs that depend on fisheries, on tourism, on restaurants, boat building, maintenance, shipping, and the list goes on. The Presiding Officer is from Maryland, which is another ocean State. He is clearly aware of the importance of that ocean economy.
As things get harder for the species to survive and thrive, sooner or later it will get harder for the economies they support. Let me give my colleagues a specific example: the tiny pteropod, a type of snail, which is about the size of a very small pea. It is also known as the sea butterfly because its foot has adapted into two butterfly-like wings which allows it to propel itself around in the ocean. These images show what can happen to the pteropod's shell when the creature's underwater environment is lacking in those compounds and becomes more acidic. That is not good for the pteropods.
Another study compared pteropods incubated in sea water with today's pH to pteropods incubated in water with the acidity and chemical conditions projected for the year 2100. The study found a 28-percent decrease in shell growth. Maintaining their shells against that acidity requires energy--energy that would otherwise go into other biologic processes such as growth or reproduction. So increasing ocean acidity is an external stress that makes it harder for species such as the pteropod to survive.
Who cares about the lowly pteropod? Well, salmon do. Forty-seven percent of the diet of some salmon species in the Pacific is pteropods. The salmon fisheries that support coastal jobs and economies also care about the salmon. Ocean fishing in the United States overall is a multibillion-dollar industry connected to hundreds of thousands of livelihoods, and we should care about our fisheries industry, even if one doesn't care about the salmon or the lowly pteropod.
These unprecedented changes in ocean acidity are not happening alone, unfortunately.
These changes come along with dramatically changing ocean temperature, which is also driven by the same carbon pollution. Just recently, NOAA proposed listing 66 species of coral as endangered or threatened, citing climate change as the driver of those species' three key threats: disease, warmer seas, and greater ocean acidification. When you add to those three conditions the preexisting stressors, such as nutrient pollution and destructive fishing practices, well, 35 percent of the world's reefs are classified as in a critical or threatened stage.
Scientific projections indicate that coral reef ecosystems could be eliminated in 30 to 50 years. The young pages who are on the floor of the Senate listening to this speech may very well live into a time when coral reefs and the ecosystems surrounding them are extinct. The death and decline of coral reefs, which are the most diverse ecosystems on the planet, in turn wounds hundreds of other species that call the reefs home. When a reef ecosystem collapses and does not recover, it quickly becomes dominated by algae, and the rich mix of species developed over hundreds of millions of years that was once present there then disappears.
Scientists think the coral reefs off the coast of Papua, New Guinea offer a window into future effects of ocean acidification because there are natural emissions of carbon dioxide which bubble up from the sea floor through the ocean and raise the concentration making the sea water more acidic. Researchers have found that many species, especially the more complex framework-building corals, which provide shelter to other organisms, do not thrive where the pH is lower.
These are two photographs taken in the same reef. We see how rich and vibrant this reef looks away from the carbon dioxide. Here, near the carbon, where the acidification is higher, it is a shadow of the healthy reef. The human-driven acidification of the ocean is capable of causing--indeed is destined to cause if we do nothing--a serious imbalance in the ocean's complex ecology. The external stress of carbon pollution will result in a new equilibrium in ocean ecosystems.
When we consider what this portends for our food security, for our planet's biodiversity and economically for ocean-based industries, we cannot afford to ignore these changes that are happening, that are measurable in our oceans.
Unfortunately, ignoring it is exactly what we are doing by failing to curb carbon pollution. There are high stakes involved. Our oceans cover 70 percent of the planet. We cannot change their chemistry without expecting profound consequences. It is time we realize we are, in fact, part of the very food chain being disrupted by the mounting acidification of the ocean.
The disruption of international fishing due to climate change and acidification threatens to destabilize local and global economies and compromise a major basic food source. How much? How much are we willing to sacrifice for the luxury of letting corporate polluters foul our planet with unchecked CO2 emissions? Carbon pollution from fossil fuels is depleting the health of the oceans as well as affecting the atmosphere. Unless we take serious action to reverse course, the consequences may be dire. We are sleepwalking through history. I implore my colleagues to heed the clear and persistent warnings that nature is giving us: to acknowledge the responsibility presented to us in this moment and to respond appropriately before it is too late.
I yield the floor.

Deceptive December
Friday, November 30, 2012
By Daniel de la Calle

December in the Southern Hemisphere equals summer heat and the end of the school year, but thanks to the winds from the north we still get snowflake and icicle lighting on the streets of Rio de Janeiro and the ever-present image of that famous obese man promising presents, provokingly overdressed with those boots and red coat.

Let's begin this confusing month with our classic news update on Ocean Acidification and the state of the world's seas:

≈≈≈≈This past Tuesday Governor Chris Gregoire made Washington State the first to adopt a policy to take on Ocean Acidification after signing an executive order underscoring the importance of recommendations from her Blue Ribbon Panel On Ocean Acidification.  The order signed by Gregoire, whose term will end in January, calls on the state to invest more money in scientific research, curb nutrient runoff from land, and push for cuts in greenhouse gas emissions on a regional, national and global scale.
“A healthy ocean is critical to our health and our coastal economies.  We have learned that human caused emissions of carbon dioxide are dramatically altering the ocean’s chemistry at an alarming rate.  These emissions, mostly resulting from burning fossil fuels, are now threatening our ocean ecosystems. Ocean acidification is yet another reason to quickly and significantly reduce emissions of carbon dioxide across the planet,” said Gregoire.
“Let’s get to work,” Gregoire told  audience at the Seattle Aquarium, adding that she would propose that the legislature reallocate $3.3 million in state funding to pay for research and other actions. “Let’s lead the world in addressing this global challenge.”

≈≈≈≈Scientists from NOAA, British Antarctic Survey, Woods Hole Oceanographic Institution and the University of East Anglia discovered severe dissolution of the shells of living pteropods in the Southern Ocean during a science cruise in 2008.
The team examined an area of upwelling, where winds cause deep cold water to be pushed upwards from around 1,000 meters to the surface of the ocean.  Upwelled water is usually more corrosive to a particular type of calcium carbonate (aragonite) that pteropods use to build their shells.  The point at which this occurs is known as the "saturation horizon".  The team found that the combined influence of ocean acidification and natural upwelling meant that in some areas the saturation horizon was around just 200m - the upper layer of the ocean where pteropods live.
"Co-author and science cruise leader, Dr Geraint Tarling from BAS, said: “Although the upwelling sites are natural phenomena that occur throughout the Southern Ocean, instances where they bring the ‘saturation horizon’ above 200m will become more frequent as ocean acidification intensifies in the coming years. As one of only a few oceanic creatures that build their shells out of aragonite in the polar regions, pteropods are an important food source for fish and birds as well as a good indicator of ecosystem health. The tiny snails do not necessarily die as a result of their shells dissolving, however it may increase their vulnerability to predation and infection consequently having an impact to other parts of the food web.”"
The results of the study are published in the journal Nature Geoscience.

≈≈≈≈The Smithsonian Magazine recently published the results of new research done by Georgia Institute of Technology revealing how corals send out chemical signals to recruit the help of goby fish in removing toxic seaweed.  If turtle weed, a toxic seaweed that causes bleaching, gets tangled up on coral branches "the researchers worked out how the coral contacts the gobies to let them know that they need their hedges trimmed. Once the coral gets hit with chemicals from the invading turtle weed, it releases its own chemical signal—an emergency call to gobies—within 15 minutes. And, within another 15 minutes or less, gobies receive the message and swoop in to nibble away at the encroaching foliage."
"It’s also possible that such subtle chemical signals could be disrupted by ocean acidification. Clownfish and damselfish raised in seawater with the acidity scientists predict we’ll see in the year 2050 have trouble identifying scents in seawater to find their homes or avoid predators. If these gobies have similar problems, the impacts of acidification on reef communities could be greater than expected."

After the Storm
Friday, November 16, 2012
By Daniel de la Calle

The storm passed and so did the election, strangely intertwining both in a way that made hard to distinguish one from the other.  In a world steamrolling to global weirding certain people call a late October hurricane in Manhattan "the new normal".  For some absurd reason such a catchphrase has also become political, either tabu, denied, or embraced and yelled with sad predictability.  
I do not have the answers, cannot recite the facts, numbers, figures, correlations or graphics and wont pretend I do.  If the whole issue is tabu to you chances are you stumbled upon this post and are shaking your head in disgust.  If you believe, worry and despair you probably find the futile comfort and warmth of this small reflection of your credo.  I simply and desperately wish we could all quietly agree the storm showed once again how mighty strong nature is, how easily it turns a cargo boat into a sinking toy and it blows the million dollar homes like dandelion seeds in July.  Maybe then being humble, respectful, watchful and preventive will also become the new normal.
Some news to keep afloat in the current surge of information; we do not want the blog to flood too.  November feels the longest month of the year:

Chris Gregoire formed a 28-member panel to work on a 43-item list of projects and 20 top priority measures on Ocean Acidification the state could tackle prior to the upcoming state legislature session in January.
"Potential top priorities include:
1 Reducing air emissions that can be linked to local ocean water acidity.
2 Reducing amounts of nutrients flowing into local sea water. These measures could involve overhauling sewage treatment plants and other sewage system to meet standards that still need to be set..
3 Exploring using salt-water vegetation to combat the impact of ocean acidification.
4 Improving and expanding monitoring of ocean acidification."

13 News for the 31st
Wednesday, October 31, 2012
By Daniel de la Calle

Three years ago you really needed to scrape at the bottom of the barrel to come up with news on the web about Ocean Acidification.  Today I am "only" posting 13 items and have to leave at least 10 more out:
≈≈≈≈64% of the waters existing outside national jurisdiction, the "high seas", are yours.  And mine. As John Platt rightly writes in a recent Mother Nature Network article, "according to the United National Law of the Sea Convention, these unregulated bodies of water — and the fish and minerals they contain — belong to all of mankind and should be used to serve the common good."
The new TerraMar Project wants to protect those high seas.  If you visit their site you can claim a parcel of the ocean, take a virtual dive with Google, friend a marine species or find interesting educational projects. Although the main purpose of the website is to celebrate the oceans, the website does address the various threats to life inside those waters, from plastic pollution to illegal dumping, from overfishing and whaling to Ocean Acidification.

≈≈≈≈Sweden wants trash and wants it badly.  The Scandinavian nation is facing an unusual problem since their waste-to-energy program began running out of source material.  20% of Sweden's district heating comes from garbage incinerators, but they are not producing enough waste to feed it on their own, so 800,000 tons of trash are being imported every year from neighboring European countries (mainly for those new rich, the Norwegians) to power plants.  That is how Norway has ended paying Sweden to take their trash and then receives the residue polluted ashes, filled with heavy metals, back to bury in home soil.

≈≈≈≈A CBS news piece about Ocean Acidification and oyster farming in Washington State.


≈≈≈≈The Smithsonian announced this week the launching of a $10 million project to study coastal marine biodiversity and ecosystems around the world over a long period of time.
"The Tennenbaum Marine Observatories will be the first worldwide network of coastal ecological field sites, standardizing measurements of biological change. By studying sites with Smithsonian experts in biology, ecology and anthropology, and using technologies like DNA sequencing, the project will provide an unprecedented understanding of how marine biodiversity is affected by local human activities and global change, such as ocean warming, acidification and rising sea levels."
"The project will have five field sites: the Smithsonian Environmental Research Center in Edgewater, Md., on the Chesapeake Bay, the Institution’s marine station at Fort Pierce, Fla., Carrie Bow Cay in Belize and the Smithsonian Tropical Research Institute’s two locations in Panama—Bocas Del Toro on the Caribbean and Naos station on the Pacific. As the project grows, the Smithsonian will establish additional research sites with collaborators around the globe to monitor coastal ocean health, with the goal of at least 10 new sites within the next decade."

≈≈≈≈Interesting Op-Ed piece on the NY Times a couple weeks ago about "How to Catch Fish and Save Fisheries".  Environmental ministers from numerous countries met last week to, for a second time, try to reach an agreement that protects 10% of the world's oceans.  As Carl Safina and Brett Jenks point out, the situation around the world is dire, but there is still hope because we have not reached a point of no return yet. The biggest challenge, but also a big portion of the solution is in the hands of small-scale fisheries and the expansion of TURF (Territorial User Rights Fisheries) reserves.

It will provide critical baseline data on the changes in chemistry or acidification in those remote seas and will also be first of its kind about the relative acidity–expressed as pH–of the waters in McMurdo Sound, Antarctica."
"Deployed by divers under the sea ice and left in place at the end of the 2011-2012 Antarctic research season, the sensor gathered data through the month of June, which is the height of winter in the Southern Hemisphere. Data gathering ended when the instrument’s battery failed in the frigid waters. Having a pH baseline will provide an important benchmark for scientists to begin to test whether certain species have the physiological and genetic characteristics to adapt to projected change."

2. Divide your rubbish onboard, take it home to be composted or recycled. Use plastic as little as possible and never never let it risk going overboard.
3. Use diesel as little as possible or, if you can, convert to bio fuels.
4. Conserve water with foot-pedal sinks and dish washing.

Not Only Ocean Acidification
Thursday, July 12, 2012
By Daniel de la Calle

Marine researchers from around the world are in Cairns, Australia, this week for the 12th International Coral Reef Symposium (July 9-13):
"From Cairns, 2,600 scientists have signed a Consensus Statement on Climate Change and Coral Reefs.
The consensus statement calls for a worldwide effort to overcome growing threats to coral ecosystems and to the livelihoods of millions of people who depend on them. It is urging immediate action to stave off what the scientists are calling "escalating damage" to coral reefs, as a result of rising sea temperatures, ocean acidification, overfishing and pollution from the land.
The World Resources Institute has also just published a new report called Reefs at Risk Revisited in the Coral Triangle. The report, a map-based analysis of threats to coral reefs around the world, particularly hones in on the countries of the Coral Triangle - Indonesia, Malaysia, Papua New Guinea, the Philippines, Solomon Islands, and Timor-Leste.
According to the report, more than 85% of reefs within the Coral Triangle region are threatened by local stressors, such as overfishing, pollution, and coastal development.

Speaking from Cairns at the ICRS2012, Jeremy Jackson, a senior scientist from the Smithsonian Institution, said reefs globally have seen severe declines in coral cover over several decades. 

In the Caribbean, for instance, he said 75-85% of the coral cover has been lost in the past 35 years. 

Jackson, the 2012 recipient of the Darwin Medal, said that even Australia's Great Barrier Reef, one of the best-protected reef ecosystems on the planet, has experienced a 50% decline in coral cover in the past 50 years.

.
Jackson said climate change is making this already rapid decline of coral reefs worse. He also touched on how climate change is causing increased droughts, agricultural failure and sea level rises at much faster rates.

"That means what's good for reefs is also critically important for people and we should wake up to that fact," Jackson said. "The future of coral reefs isn't a marine version of tree-hugging but a central problem for humanity."

According to the marine experts, coral reefs provide food and livelihood for many tens of millions of coastal inhabitants globally, as well as having tourism spin-offs. The scientists estimate that reefs provide upwards of US$170bn to US$375bn in goods and services globally each year."

1. Drive a more fuel-efficient car can translate in $18,000 savings over the car's lifespan.
2. Using LED bulbs instead of conventional ones. You get the same light for 15% of the electricity (saving $100 annually).
3. Washing clothes in cold instead of hot water (another $100).
4. Power strips curb "phantom loads" and reduce the electricity bill (just a strip for the printer can save $130 a year).
5. Sealing and insulating the house properly. Air leaks can be responsible for 15 to 25% of your heating and cooling.

How long can you hold your breath for underwater? A minute? Two? And what do you think the world record in static apnea might be? 1, 2, 5, 10, 15 minutes?
In early June German free diver Tom Sietas, 35, set the new world record competing with former world record holder, Brazilian Ricardo Bahía, by holding his breath for 22 minutes and 22 seconds (no typo). People can also accomplish incredible things underwater.
