Snowden leaves Moscow airport

August 1, 2013

Russia’s interfax news agency reported  at 1354 CET that Snowden had now left Moscow’s Sheremetyevo Airport and crossed the Russian “border”.

Interfax: 

MOSCOW. Aug 1 (Interfax) – The Federal Migration Service has issued former CIA employee Edward Snowden with a certificate, which allows him to leave the Sheremetyevo airport’s transit zone, lawyer Anatoly Kucherena told Interfax on Thursday.

“I have just delivered documents from the Russian Federal Migration Service. He can now leave the transit zone,” said the lawyer, who is rendering legal services to the U.S. whistleblower.

The saga continues.

I suppose he will in due course end up in Latin America.

Economists are – by and large – religious or political advocates

August 1, 2013

A recent article by March Buchanan in Bloomberg got me to wondering why “Economists” and “Economics” – in spite of their gross and sometimes spectacular failures – have the high status they do. I come to the conclusion that “Economists” are – by and large – just religious or political advocates and “Economics” is no more than a study of social behaviour.

Is Economics a Science or a Religion?

The idea of economics as religion harks back to at least 2001, when economist Robert Nelson published a book on the subject. Nelson argued that the policy advice economists draw from their theories is never “value-neutral” but foists their values, dressed up to look like objective science, on the rest of us.

Take, for example, free trade. In judging its desirability, economists weigh projected costs and benefits, an approach that superficially seems objective. Yet economists decide what enters the analysis and what gets ignored. Such things as savings in wages or transport lend themselves easily to measurement in monetary terms, while others, such as the social disruption of a community, do not. The mathematical calculations give the analysis a scientific wrapping, even when the content is just an expression of values.

Similar biases influence policy considerations on everything from labor laws to climate change. As Nelson put it, “the priesthood of a modern secular religion of economic progress” has pushed a narrow vision of economic “efficiency,” wholly undeterred by a history of disastrous outcomes.

The practice of the black-magic that is considered economics – for it is certainly no science in the Popper sense – gets much of its cloak of respectability from the fact that the Nobel Prize exists (more correctly the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel).  

The Nobel prize in Economics should never have been created. In fact Nobel never wanted one and he is probably spinning in his grave as prize winners, one after another, prove – at best – to be mere historians and – at worst – religious or political zealots.  The prize adds more stature to the discipline of economics than it deserves. Almost every economic theorist has developed wonderful hindcasts but few – if any – have produced theories which can consistently make correct forecasts.

Wikipedia – The Prize in Economics is not one of the original Nobel Prizes created by the will of Alfred Nobel. ……. In his speech at the 1974 Nobel Banquet Friedrich Hayek stated that if he had been consulted whether to establish a Nobel Prize in economics he would “have decidedly advised against it” primarily because “the Nobel Prize confers on an individual an authority which in economics no man ought to possess… This does not matter in the natural sciences. Here the influence exercised by an individual is chiefly an influence on his fellow experts; and they will soon cut him down to size if he exceeds his competence. But the influence of the economist that mainly matters is an influence over laymen: politicians, journalists, civil servants and the public generally.”

The Nobel family are among the harshest critics of the Economics Prize being associated with Alfred Nobel:

“The Economics Prize has nestled itself in and is awarded as if it were a Nobel Prize. But it’s a PR coup by economists to improve their reputation,” Nobel’s great great nephew Peter Nobel  told AFP in 2005, adding that “It’s most often awarded to stock market speculators …. There is nothing to indicate that [Alfred Nobel] would have wanted such a prize.”

Members of the Nobel family are among the harshest, most persistent critics of the economics prize, and members of the family have repeatedly called for the prize to be abolished or renamed. In 2001, on the 100th anniversery of the Nobel Prizes, four family members published a letter in the Swedish paper  Svenska Dagbladet, arguing that the economics prize degrades and cheapens the real Nobel Prizes. They aren’t the only ones.

To make it worse the Prize  is now “available to researchers in such topics as political science, psychology, and sociology”.

The political advocacy which is inherent in the theses promoted by Nobel Economics laureates have led to spectacular failures. Milton Friedman and his rabid monetarism gave rise to many of the crises today, Muhammad Yunus and the Grameen bank with their concept and practice of microcredit have exacerbated the risks of the debt trap into which so many small farmers have fallen. Krugman’s politics are essentially of the left and usually encourage profligacy. His analyses are more destructive than constructive and he has fault to find with almost every other theorist cutting across all political boundaries. He himself has yet to advocate any consistently successful theories. Amartya Sen focuses on analysing the “economics of poverty” but has nothing real to offer for its alleviation beyond platitudes representing his own political values from his ivory tower.

The world’s economies lurch from one crisis to the next but rarely are the crises foreseen. The only constant that can be observed is that growth – when it happens – leads to the improvement of the human condition but no “economic theory” has been able to deliver sustained growth. Growth – when it happens – achieves more for poverty alleviation than any social welfare program. Real wealth creation achieves more in achieving full employment or achieving social equality than merely redistributing a static pot of wealth.

As Mark Buchanan writes:

There’s a real danger in seeing economics as an objective science from which all values have been stripped.

It may be that “economics” will always be subject to the vagaries of human attitudes and behaviour and – since these are never constant or rational – that economics theory applied to political reality can never be more than a very short-term action plan.

Results falsified but only “inadvertently” by researchers at Queensland University of Technology

July 31, 2013

There are strange goings-on down under at the Queensland University of Technology (QUT).

The story has all the necessary ingredients for a genuine scandal. Falsified results in a grant application and a paper, the paper retracted, grant money awarded on the basis of the alleged results, a University with commercial interests in the alleged results of the alleged research, a whistleblower’s name illegally revealed by the Vice Chancellor of the University, and the Crime and Misconduct Commission accused of colluding with the University.

The University has found that the falsification of results was inadvertent and not fraud and nothing to worry about.

===============

UPDATE: Now the QUT “investigation” which came to the “finding” that the falsification was “inadvertent” and not fraud is itself being questioned by the federal agency that gave the scientists a $275,000 grant for stem cell work.

31st July: The National Health and Medical Research Council is not satisfied with some of QUT’s investigative procedures and wants a review by the Australian Research Integrity Committee. The move is unusual, with the ARIC set up in 2011 to ensure research allegations of misconduct are investigated properly taking on just a handful of cases.

============================

It is compelling reading and lives up to the convoluted tradition of Australian politics. But I have some difficulty in telling the “good guys” from the “bad guys” – if there are any “good guys” in this saga at all!

29th July: QUT reputation at risk after grant application and research mistakes

RESEARCHERS at one of Queensland’s top universities have admitted to incorrectly filling out a lucrative grant application in a mistake that could cost the university hundreds of thousands of dollars.

The “inadvertent” mistake by Queensland University of Technology scientists has put the university’s reputation at risk, the Vice-Chancellor says. The National Health and Medical Research Council is examining the circumstances under which it awarded QUT a $275,000 grant for research, and QUT boss Peter Coaldrake said the university faced having to pay it back. 

Whistleblowers have exposed errors in the reporting of embryonic stem cell research, prompting an internal probe into alleged misconduct and the retraction of a key research paper. The lead researcher has admitted to The Courier-Mail that an “inadvertent mistake” occurred in the writing of the grant application and an associated scientific paper published in 2010.

The NHMRC awarded the money to fund research into stem cell cultivation at QUT’s prestigious Institute for Health and Biomedical Innovation. The scientists were working on developing a “world-first” product to safely grow human cells in the lab without the use of risky animal proteins.

However, university insiders accused the researchers of exaggerating some results. “It was alleged that some data in the grant application had been falsified,” Prof Coaldrake said.

The scientists were subsequently cleared by a QUT inquiry. QUT later told the NHMRC there was no misconduct in the grant application. The journal involved has since retracted the article, a highly unusual step. …

30th July: QUT researchers cleared of fraud

AN “inadvertent” mistake in filling out a grant application by researchers at Queensland University of Technology saw the university awarded $275,000 for stem cell research and which has subsequently lead to an internal probe into research misconduct and the retraction of a research paper, the Courier Mail reported yesterday.

The NHMRC awarded the grant for research into stem cell cultivation at QUT’s Institute for Health and Biomedical Innovation. The scientists were working on developing a “world-first” product to safely grow human cells in the lab without the use of risky animal proteins, the Courier Mail said.

But the researchers were accused of falsifying some results, even though the scientists were subsequently cleared by an internal inquiry of any wrongdoing.

The whistleblowers who drew attention to irregularities in the research say QUT has a conflict of interest because it is a shareholder in a company called Tissue Therapies which was set up with the express purpose of developing and commercialising products based on the research.

30th July: Premier Peter Beattie gave QUT researchers in grant controversy an extra $225,000 for related work

QUT scientists at the centre of a controversy over a $275,000 federal grant for a now discredited journal paper also received $225,000 from then premier Peter Beattie for related work, as part of a 2007 funding package worth more than $1 million.

But while QUT has informed the Crime and Misconduct Commission and the National Health and Medical Research Council about errors in the application for the federal grant and the retraction of a key research paper, the university has not told the State Government.

31st July: QUT vice-chancellor Peter Coaldrake reports himself to CMC for disclosing whistleblower’s identity

QUT Vice-Chancellor Peter Coaldrake has reported himself to the Crime and Misconduct Commission after disclosing the identity of a protected whistleblower.

Prof Coaldrake named the person in an interview with The Courier-Mail in which he discussed the allegations by the whistleblower of research misconduct by QUT scientists. Prof Coaldrake later turned himself in to the CMC.

QUT later confirmed the employee’s status as a whistleblower protected by the Public Interest Disclosure Act. This law makes it an offence for public officials to disclose the person’s identity without their consent, except for the purposes of official investigations. The offence carries a fine of up to $9000. …… In the same interview Professor Coaldrake declined to name four academics from other universities involved in investigating research misconduct allegations involving a retracted scientific paper. He said this was because he wasn’t sure if the academics’ identities were known by the stem cell researchers being investigated. … QUT has declined to explain why Prof Coaldrake volunteered the name of the whistleblower.

Ahluwalia’s PhD cleared of fraud by Imperial College

July 31, 2013

I have posted extensively about Dr. Jatinder Ahluwalia’s scientific misconduct while at University College London and earlier at Cambridge. He was awarded his PhD by Imperial College London in a collaborative industrial doctorate with Novartis as his sponsor.

Following the ruckus, Imperial College investigated his PhD but have now cleared him of any fraud but their report does complain that access to Ahluwalia’s lab books was restricted by Novartis and only supervised access was permitted. Ahluwalia’s career in academia has virtually come to an end but I do have a suspicion that his PhD supervisors at Imperial College (Dr. Istvan Nagy) and at Novartis ( Dr Marco Compagna) cannot be completely free of all blame.

On the atmosphere in the research group, Dr Nagy suggests that Jatinder Ahluwalia was under no pressure to publish or to produce results in Dr Nagy’s group and Dr Nagy felt that a climate to produce fraudulent data did not exist, since there was no reason to produce papers in a hurry.
From discussions with Dr Nagy on the set-up of Dr Ahluwalia’s supervision arrangements it appears that the separation between Novartis and Imperial may have led to errors in supervision, where any mistakes that Jatinder Ahluwalia may have made in methodology and interpretation could not easily be checked.

THES and Retraction Watch cover the story.

THES: 

Imperial College London has cleared disgraced researcher Jatinder Ahluwalia of committing fraud during his industrial doctorate at the institution. 

However, a report setting out the finding also reveals that Imperial experienced considerable difficulties in investigating its suspicions due to the reluctance of the industrial collaborator on Dr Ahluwalia’s studentship to grant access to his lab books.

The investigation was announced in August 2011, after Dr Ahluwalia’s co-authors agreed to retract a 2003 Journal of Neurochemistry paper, of which he was first author, following the failure of his former supervisor, Istvan Nagy, to replicate its findings.

In 2010 a paper written while Dr Ahluwalia was a postdoctoral researcher at University College London was retracted by his former boss, Anthony Segal, after a UCL committee found that he had manipulated his results and had probably interfered with colleagues’ experiments to cover his tracks.

It subsequently emerged that Dr Ahluwalia had been dismissed from the University of Cambridge’s PhD programme in 1997 after his supervisor suspected him of faking results.

He then did a PhD at Imperial between 1999 and 2002, funded by a Medical Research Council “Case” studentship, in collaboration with the pharmaceutical company Novartis.

In 2009, while the UCL investigation was ongoing, Professor Segal informed Imperial of his suspicions about the 2003 paper. No misconduct was found during a subsequent investigation, but the paper was corrected in 2010 after “an arithmetical error” was identified.

Following its 2011 retraction, a six-person panel investigation panel – which included Imperial’s pro-rector for education, dean of students and student union president – was formed to check Dr Ahluwalia’s PhD work for fraud. None was found. …..

Dr Ahluwalia left the University of East London, where he had been a senior lecturer in pharmacology, in 2011 following an internal investigation. His current whereabouts are unknown.

Retraction Watch: 

We’ve uploaded the entire report here.

Ahluwalia, as Retraction Watch readers may recall, has had a paper in Nature retracted, as well as one in theJournal of Neurochemistry. The Nature retraction followed an investigation at University College London, where he was a postdoc, and he then left the University of East London after we reported that he had been dismissed from Cambridge the first time he had tried to get a PhD.

Imperial, where he earned his doctorate, began investigating more than two years ago. They began looking in whether he should lose his PhD after the Journal of Neurochemistry retraction, because that paper formed the basis of his thesis. They found:

The panel determined that there was no evidence of research misconduct in Dr Ahluwalia’s thesis. It noted that fraudulent activity by Dr Ahluwalia had been reported elsewhere but that this did not suggest that misconduct had occurred at Imperial. As no evidence of fraud or misconduct at Imperial had been identified, the award of the PhD should stand.

Part of the reason the investigation took so long was because of problems accessing Ahluwalia’s data, given that his supervisor was a :

An initial confidential review of the thesis and publications was carried out by a private firm contracted for the purpose and identified the need for further investigation. In parallel to this a protracted negotiation ensued between the College and Novartis for the panel to have access to Dr Ahluwalia’s notebooks which were in Novartis’ possession. Eventually supervised access to the notebooks on Novartis’ premises was agreed by Novartis.

Europe is paying the price for its infatuation with renewable energy

July 30, 2013

Electricity and the price of its generation is now one of the most fundamental parameters which steers the economy and industry and ultimately the level of unemployment in any country. It ought not to be subject to the misguided whims and fancies of “feel-good” environmentalism, but for the last 2 decades much of Europe has been travelling down a cul-de-sac chasing a mirage. Instead of just focusing on generating electricity at the lowest possible cost while keeping the air and water sufficiently clean, politicians have been lured down the renewable energy path in a fantasy of saving the world from the imaginary dragon of carbon dioxide emissions. Instead of just using wind and solar energy in the special niches they are suited to, they have been subsidised and promoted as basic generation which is a role they cannot fulfill.

The US with its much lower electricity prices now has a significant competitive advantage over Europe and will come out of the  recession much faster as it creates jobs.

As David Garman and Samuel Thernstrom write in the Wall Street Journal:

Europe has bet big on wind and solar energy, and many environmental advocates would like America to follow. Wind and solar have a role in the U.S. energy economy, but we would be wise to see the cautionary tale in the European experience and adjust our plans accordingly.

Wind and solar generate 3.5% of America’s electricity today, but Denmark gets 30% of its electricity from wind and hopes to produce 50% by 2020. Germany, Europe’s largest national economy, produces roughly 12% of its electricity from wind and solar today, and it wants renewable energy to account for 35% of electricity generation by 2020.

Clean energy powered by renewable resources is understandably attractive. But the honeymoon with renewables is ending for some Europeans as the practical challenges of the relationship become clear.

The first challenge is cost. Germany has reportedly invested more than $250 billion in renewable energy deployment, and its households pay the highest power costs in Europe—except for the Danish. On average, Germans and Danes pay roughly 300% more for residential electricity than Americans do.

But it is not just price that is at issue. The reliability of electricity supply is not helped by the inherent instabilities of having too much dependence on intermittent and unforeseeable sources.

Another challenge of Europe’s growing dependence on renewable energy is far more serious: the potential loss of reliable electrical supply. It’s one thing to ask consumers to pay more for cleaner energy; it’s another to force them to endure blackouts. …..

……. Grid operators generally rely on coal and nuclear plants to meet baseload demand while modifying gas and hydroelectric power output to meet shifting demand. But electricity from wind and solar is variable and intermittent. Nature determines when and how much power will be generated from available capacity, so it is not necessarily “dispatchable” when needed.

When intermittent renewables are small players in the grid, they can be easily absorbed. But as they reach European levels of penetration, the strain begins to show. There are increasing reports of management challenges resulting from wind and solar across the European grid, including frequency fluctuations, voltage support issues, and inadvertent power flows. Anxious operators are concerned about potential blackouts.

In an April 17, 2012, letter to EU Commissioner for Energy Gunter Oettinger, for example, Daniel Dobbeni, the European Network of Transmission System Operators president, said grid operators are “deeply concerned about the difference in speed between the connection of very large capacities of renewable energy resources and the realization in due time of the grid investments needed to support the massive increase of power flows these new resources bring.” He also expressed great concern “about the potential destabilizing effect of outdated connection conditions for distributed generation that are not being retrofitted anywhere fast enough.”

The article continues with a warning to the US about unhealthy subsidies.

There is also an important lesson in the European experience with energy subsidies: Focus incentives so they reward the right behavior. Lavish subsidies for wind and solar have changed Europe’s generation mix, but the costs have been high because the subsidy structure prioritized mass deployment rather than efficiency, reliability and innovation. Even in the U.S., the wind-production tax credit has occasionally produced “negative pricing”—that is, turbine operators pay grid operators to take their power even though it isn’t needed, just so the wind generators can collect tax credits.

Facebook and Twitter are “publishers”, not merely “couriers”

July 30, 2013

Social media like to claim that they merely provide a “platform” or  are just “communication enablers” or only provide “communication media” and therefore that they are not responsible – and should not be held responsible – for the content they disseminate.

But they protest too much.

It is quite wrong to compare Facebook or Twitter or LinkedIn to a telecommunications enterprise or a postal service or a courier service or an e-mail service provider. In all of these a specific identifiable “sender” directs a communique to a specific, identified “receiver”. The carrying of the communique to the specific receiver is the service provided by the communications enterprise and is not in any sense “publishing”. The service provided by the social media is more than just the provision of a soap box in Hyde Park (a platform) or the provision of a Board or a Wall in a town square onto which a newspaper could be appended. Any website could be a platform for comments but the website owner must take ultimate responsibility for the content published on the web-site.

Facebook and Twitter disseminate their users communiques to a general audience without discriminating as to who may receive the communique. Their business models rely on this audience being as large as possible. Their advertising revenues depend upon the dissemination being as wide and as “indiscriminate” as possible. They are not so different to a radio or a TV broadcast where the broadcaster tries to reach as large an audience as possible. The broadcaster is clearly responsible and accountable for the content of the broadcast. A free newspaper being distributed at all Metro stations but where revenues are dependent upon advertising also has a responsible publisher. Any advertising revenue accrues to the publisher.

The clincher for me is that the placement of advertisements based on circulation is decisive proof of the existence of a publisher. All published material does not contain advertising. Not all advertising is proof of the existence of a publisher. A billboard or sandwich-board owner for example, is not a publisher. But the mere existence of advertising based on circulation numbers or “reach” or any similar parameter is conclusive proof – I think – of the existence of a publisher. And it is the person or organisation responsible for the circulation who takes the advertising revenues and in consequence must be the responsible and accountable publisher.

Freedom of speech does not really enter the argument. The publisher may choose to publish whatever he pleases. He may refrain from “censoring” his users if he so wishes. Or he may – at some cost – ensure that the content he publishes meets criteria that he sets himself. But he remains responsible and accountable for what he publishes. Facebook and Twitter cannot abdicate their responsibility because they choose not to exercise the quality control they could.

It seems to me to be self-evident that Facebook and Twitter are not “billboards” or “sandwich-boards” but are full fledged “broadcasters”. And a broadcaster is a publisher. They could take responsibility for the content they disseminate if they wanted to. It just costs. They can be held accountable for what they indubitably do publish – and they should.

A retraction can achieve more publicity than the original paper

July 30, 2013

A jaundiced view of retractions and questions of a cynical kind:

  1. Could an article or paper be deliberately written so as to be retracted later for the ensuing publicity?
  2. Can a deliberate retraction be managed so as to generate credit for the journal or the author who requests the retraction?
  3. And is it not “perfectly correct” to cite a retracted paper in a subsequent paper as a  “publication (retracted)”?

A retraction – if sufficiently “interesting” – can get more publicity than the original paper. It may be a cliche but it is nonetheless true  that there is no such thing as bad publicity. And if the retraction is at the “request of the authors” the author may actually demonstrate and even build a reputation for integrity!

This story at Retraction Watch of an article pulled by Slate raises my suspicions that just publicity was actually the objective.

RetractionWatch: 

Slate has retracted an essay they published as part of a partnership with Quora, an online question-and-answer site, after acknowledging that they “did not vet the piece properly.”

The piece garnered hundreds of comments, many of which questioned whether its claims were legit, and some of which pointed out that the author may have posted questionable material on the web before.

This now appears where the article, originally published at 5:01 p.m. on Thursday, July 25, originally did:

Editor’s note: On July 25, Slate published in this space an essay from its partner site Quora titled “Are Doctors Biased Against Obese People?” Because the piece did not meet our editorial standards, we have taken it down.

On Friday at 6:09 p.m., brandchannel started a post about the article with a quote from the piece:

When I was pregnant, one OB called me disgusting and told me to have an abortion.

brandchannel doesn’t mention the retraction, which Slate tells us happened Friday night, just over 24 hours after it as originally posted. But brandchannel anticipated that move, including the entire Slate-Quora piece saved for posterity, …..

I note also from Professor Debora Weber-Wulff’s blog that retracted papers still show up being cited – as retractions – in other papers. The paper is in PLoS and is supposedly a peer-reviewed online publication.

36. Rathinam C, Klein C (2012) Retraction: transcriptional repressor gfi1 integrates cytokine-receptor signals controlling B-cell differentiation. PLoS One 7.

Retraction? Are they citing the retraction of the article as a reference for what had been stated in the article retracted? 

Retracted papers are also being included in CV’s! I suppose that the paper was accepted for publication – even if later retracted – is some kind of an achievement!

It reminds me of the old story where CV’s in India would regularly include something like

“BA, 1943, University of Aligarh (fail)”.

This was considered – socially and academically – acceptable as proof that the author had at least done the course and had appeared for the examination!

Czechs jump off the renewables train to nowhere

July 30, 2013

From Power Engineering:

The Czech Republic’s government has voted to end support for renewable power generation in a bid to reduce rising consumer electricity bills.

The law proposes to stop subsidies for new projects and goes in to effect from 2014.

Subsidies for renewable-power sources have raised prices for Czech energy users in the past three years as the cost is passed on through customer bills.

Prime Minister Jiri Rusnok said in the statement, that rising electricity prices “threatens the competitiveness of our industry and raises consumers’ uncertainty about power prices.”

Only hydro, wind and biomass power plants that got construction permits in 2013 will be eligible for support if they’re completed before the end of 2014, the statement said.

Earthquakes release methane from methane hydrates

July 29, 2013

“Natural” release of methane from methane hydrates by earthquakes is more common and more significant than has been thought or accounted for in climate models.

The inescapable conclusion is that effects  being attributed by the demonisation of carbon to man made carbon dioxide emissions (even if real) may well be partly due to the natural release of such methane.  The global temperature pause for the last 17 years or so and the clear but small decline in global temperatures for the last 5 years is quite clear. At the same time emissions from fossil fuel combustion have been steadily increasing. These are a clear indication that the supposed linkage between carbon dioxide concentration and man-made carbon dioxide emissions on climate is very suspect if not completely broken.

It is also becoming increasingly clear that climate models – even though very complicated – are far too simplistic and just don’t (can’t) take all factors into account. Clouds, aerosols, particulates, solar effects, lunar cycle effects through the tides, ocean cycles and now earthquakes are all poorly understood and largely ignored in climate models. There is far more in the realms of the unknown about the climate than is known. We don’t even know what we don’t know.

David Fischer, José M. Mogollón, Michael Strasser, Thomas Pape, Gerhard Bohrmann, Noemi Fekete, Volkhard Spiess & Sabine Kasten, Subduction zone earthquake as potential trigger of submarine hydrocarbon seepage, Nature Geoscience (2013) doi:10.1038/ngeo1886

Here we present geochemical analyses of sediment cores retrieved from the convergent margin off Pakistan. We find that a substantial increase in the upward flux of gas occurred within a few decades of a Mw 8.1 earthquake in 1945—the strongest earthquake reported for the Arabian Sea. Our seismic reflection data suggest that co-seismic shaking fractured gas-hydrate-bearing sediments, creating pathways for the free gas to migrate from a shallow reservoir within the gas hydrate stability zone into the water column. We conservatively estimate that 3.26×108 mol of methane have been discharged from the seep site since the earthquake. We therefore suggest that hydrocarbon seepage triggered by earthquakes needs to be considered in local and global carbon budgets at active continental margins.

New York Times:

Dr. Fischer and his colleagues analyzed sediment cores taken in 2007 from two locations in the northern Arabian Sea where hydrates were present and seepage was occurring. They found chemical signatures in the cores suggesting that the methane flow greatly increased sometime in the mid-20th century. Looking through seismic records, Dr. Fischer found that a magnitude 8.1 quake occurred in the area in 1945. The quake, which was centered less than 15 miles from where the cores were taken, and a resulting tsunami, killed up to 4,000 people.

The conclusion was inescapable, Dr. Fischer said. “The quake broke open gas-hydrate sediments and the free gas underneath migrated to the surface.” The hydrates themselves did not dissolve. “They remain there,” he said.

Dr. Fischer said the researchers chose the core locations in the Arabian Sea because they wanted to get a better understanding of how methane seepage was related to tectonics, and the area is in an active zone where one of the earth’s tectonic plates slides beneath another. But they were not thinking about the effect of individual earthquakes, and his discovery of the 1945 quake in the records “was probably a moment I’ll never forget,” he said.

The upward flow of methane is continuing today, and the researchers do not know when it might stop. All told, they estimate that nearly 10 million cubic yards of methane have been released from the core sites over the years. But that is a conservative figure, Dr. Fischer said, because immediately following the quake the flow would have been much higher.
