Scientific Data Disappears At Alarming Rate, 80% Lost In Two Decades

samzenpus posted about 8 months ago | from the here-today-gone-tomorrow dept.

Science 189

cold fjord writes "UPI reports, 'Eighty percent of scientific data are lost within two decades, disappearing into old email addresses and obsolete storage devices, a Canadian study (abstract, article paywalled) indicated. The finding comes from a study tracking the accessibility of scientific data over time, conducted at the University of British Columbia. Researchers attempted to collect original research data from a random set of 516 studies published between 1991 and 2011. While all data sets were available two years after publication, the odds of obtaining the underlying data dropped by 17 per cent per year after that, they reported. "Publicly funded science generates an extraordinary amount of data each year," UBC visiting scholar Tim Vines said. "Much of these data are unique to a time and place, and is thus irreplaceable, and many other data sets are expensive to regenerate.' — More at The Vancouver Sun and Smithsonian."

queazocotal (915608) | about 8 months ago | (#45744523)

That's not the point.
The actual published results - even if published in an obscure journal tend to stick around _much_ more.

Even old journals which go out of publication get their archives and the rights to distribute them bought - as there is some small amount of value there, in addition to the copies in the various reference libraries around the world.

The problem is that if you are wondering about that graph on page 14 of the paper that the whole paper rests on, you can't get the original data to recreate that graph.

This is a major problem because the only way to check that graph is now to redo the whole experiment.

Why must you have their data? (0)

Anonymous Coward | about 8 months ago | (#45744743)

Reproduction of results isn't "add the numbers that they produced to see if they sum to the value they said it did". That isn't replication of science.

Since the science is supposed to be repeatable and the paper (if valid science not pseudoscience bollocks) contain enough information to do the assessment again (e.g. like a patent as supposed to be), then you MUST consider it BETTER to re-do the experiment again and collect your OWN data and see if the data fits the result of the previous paper.

What if, for example, there was a bias on the original potentiometer, making all voltages appear different from what they are? The result would be WRONG, but your method of "redoing the experiment" would NEVER show this. Doing the experiment again and producing your OWN data would.

No but it is amazing what NEW science you can do with OLD data. I've worked with the Transportable Array project for example http://www.usarray.org/researchers/obs/transportable [usarray.org] it's over a decade old and scientists are still discovering new ways to take advantage of the data and will likely be doing so for decades to come. On the other hand a lot of data is just junk due to poor quality metadata; when was that instrument calibrated? I dunno. Damn. At leat in geophysics we have the National Geophysical Data Center to curate this stuff http://www.ngdc.noaa.gov/ [noaa.gov] at least until Congress cuts it's funding.

Trying to ignore that a paper about the unavailability of scientific data is locked behind a paywall.

This is nothing new though, I do occasional conversion from ancient data formats, people need to pay better attention, imagine trying to read an 8" CP/M floppy today.

As libraries move to digital storage rather than the dead tree that's been fine for thousands of years they are inviting a catastrophe, possibly only one well aimed solar mass ejection from massive data loss.

Re:Concerning... (4, Insightful)

Dutch Gun (899105) | about 8 months ago | (#45743915)

Paper has its own issues. Talk to me about the durability of paper after you recover the books lost throughout time due to natural decay, burning (intentional or otherwise), floods, wars, and social forces (politics, religion, etc). Digital data can be easily copied and archived (when not behind a paywall, of course). It seems to me that redundancy is the best form of insurance against data loss. A solar mass is not going to wipe out every computer with a copy of important data on it, and all the relevant backups. And if it does, we're probably in a lot more trouble for reasons other than losing some scientific research.

Besides which, I sort of wonder if scientific data also follows the 80/20 rule. If so, how much are we really losing? I'm only half joking, of course, since it's difficult to ascertain the value of research immediately in some cases, but wouldn't it stand to reason that any important or groundbreaking research will naturally be widely disseminated, and thus protected against loss?

Probably not that much. I'm not claiming this is good, but I don't htink it's as bad as it appears.

If a paper is unimportant and more or less sinks without a trace (perhaps a handful of citations), then the data is probably of no importance since someone is unlikely to ever want it. Generally this is because papers tend to get more obscure over time and also get supereseded.

For important papers, the data just isn't enough: is a paper is important then it will establish some technique or result. In 20 years people will have generally already reanalysed the data and likely also independently verified the result if it is important enough. After 20 years I think the community will have moved on and the result will either be established or discredited.

I think the exception is for things that are "hard" to find such or non-repeatable such as finding fossils. Then again the Natural History Museum has boxes and boxes and boxes of the things in the back room. They still haven't gotten round to sorting all the fossils from the Beagle yet (this is not a joke or rhetoric: I know someone who worked there).

So my conclusion is that it's not really great that the data is being lost, but it's not as bad as it initially sounds.

Re:Concerning... (5, Interesting)

Anonymous Coward | about 8 months ago | (#45744251)

I designed and built the equipment for scientific experiments that will never be repeated: cochlear implant stimulation of one ear, done in an MRI. This was safe because the older implant technology had a jack that stuck out of the subject's head, and which we could connect to electronics outside the MRI itself. But the old "Ineraid" implants have been replaced, clinically, with implants using embedded electronics and usually magnets. Those are hideously unsafe to to even bring in the same *room* as an MRI, much less actually scan the brain of a person wearing one.

So that experiment is unlikely to ever be repeated. Losing the data, and losing the extensive clinical records of those subjects, would be an immense loss to science. There is especially historical data from decades of testing on these subjects that show the long term effects of their implants, or of different types of redesigned external stimulators. That data is scientifically priceless. When I started that work, we used mag-tape for data, and scientific notebooks for recording measurements. I helped reformat and transfer that data to increasingly modern storage devices several times. We went through 3 different types of storage media in 10 years, and I remember having to write software to allow Exabyte drives to find the end of the tape and add data. (Exabytes had no End-Of-Tape marker.) Preserving that data.... was a lot of work.

jabuzz (182671) | about 8 months ago | (#45744355)

No it won't because it 20-30 years we will be able to do gene therapy to "grow" or "regrow" the stereocilia and hence cochlear implants will be considered as barbaric as medieval blood letting. Consequently the data will only be of obscure historical interest.

Why would a cochlear implant ever be considered as barbaric as medieval blood letting?

In the nineties I had a friend working for a company that bought a lot of old Soviet geophysical data.

It needed some very special transcription technology but once in the clear and fed to modern 3D seismic software it revealed a lot more than the original reports gave.

Retaining old reports is nice, retaining old raw data even nicer.

I mean, I would like to check that you do find more data, so you have it, right? The raw data?

Is it torrented?

And the programs for manipulating, are they available too? And the results from it?

That makes 2x as much data you have.

Of course, if I reanalyse it, if I have any data, I now must archive it. 3x.

If anyone else wants to recreate it... 4x

Alternatively, for the cost of 20years storage, it may be possible to redo all the measures with UAVs and nanobots in future. And for less cost than 30 years storage...

Re:Concerning... (2, Insightful)

Anonymous Coward | about 8 months ago | (#45743945)

The problem is not just an issue of digital storage, but also a problem of redundancy.

In the "old days", people understood and accepted the risk that a paper copy would be lost. In fact, it was a GIVEN that they would eventually be lost (or damaged or misplaced or stolen or checked out and simply never returned). So multiple copies were kept because centuries of experience dictated that some copies would be lost no matter how strong, carefully maintained and well preserved the originals were.

Nowadays, people simply think its a matter of "copy and paste". But, as you point out, its not. Different hardware formats on top of different software formats. The card catalog with its rigid but well defined categories was switched for a nebulous and vague "tagging" system. And god help you if the files are corrupted.

clickclickdrone (964164) | about 8 months ago | (#45744031)

That's still 100 years which is a lot better than the data being talked about here.

There was a documentry on the radio this week about the loss of letter writing as a form and how alarmed biographers were getting because it's getting very hard to trace someone's life, thoughts, actions etc without a paper trail as stuff like emails, digital photos etc generally get lost when someone dies.

Personally, I find the increasing rate of loss quite alarming - so much of our lives are digital and so little is properly curated with a view to future access. We know so much about the past from old documents, often hundreds if not thousands of years old but these days we're hard pushed to find something published ten years ago.

It's not that it's a new problem as such, it's that for the first time in history we have a simple way to solve it, yet we have stupid greedy rich people who sponsor and enact laws to stop us from solving the problem.

The way to solve the problem is through massive duplication of all the data, over and over again through time. We have the technical means to do this on an unprecedented scale.

Even 1000 years ago, people had to painstakingly copy books, by hand, one at a time. And after a handful of copies were produced, there still weren't enough to guarantee that most would survive the ages, wars, fires, censorship, etc. So we generally have tiny collections from the past.

But now it's digital data. Anyone could copy it. We could have millions of copies of some obscure scientific work, all perfect duplicates. If even 0.1% of these copies survive, that's still thousands of copies.

And what do we do? We let a bunch of 1 percenters, who themselves barely know how or care to read, sponsor draconian copyright laws to stop eeryone from copying all that stuff, just on the off chance that they might copy a bunch of songs or movies that are outmoded within two years. And the commercial scienrific pulishers are some of the worst.

rnturn (11092) | about 8 months ago | (#45744959)

Some years ago I picked up a copy of "Dark Ages II -- When the Digital Data Die" by Bryan Bergeron (2002) but only now have gotten around to finishing reading (for some reason I never got past the first chapter at the time). When I bought it I had just had my own experience with the not-so-long life of digital data (some CDs I'd burned a few years earlier were already unreadable). The book's a bit dated (it says that there are many people out there with Zip drives connected to their PCs) as, obviously technology marches on, leaving older media in the dust but that's the point of the book and the ideas are still relevant. Worth looking for at your public library if you're still of the mind that a digital format is superior to everything else for long-term storage. Personally, I think we're looking at trouble if everything's converted to bits thinking that it'll always be available. Continued access to one of those aforementioned 8" CPM floppies is a good example. My failed CD-Rs are another.

And when it's passed to the public, on a thousand servers, how do you know if the one you happened to get to first is genuine or been fudged by someone with an agenda against the science? Do you think AIG would mirror honestly the genetic proof of evolution?

And at what point is it no longer the science institutions requirement to pass this data to the public? Because until then, you'll still need to pay for that access and storage. Then what's to stop every public copy being deleted because nobody cares any more? "the public" won't change storage media and veryfy contents for ever you know.

"Will this change? Probably not."

I have access to vast libraries of data that date back 30+ years, some datasets (this includes computer software too) date back to the early 70s. why? because these institutions/corporations were organized, they knew that retaining data is important and they kept up with technology to ensure that no data is lost. there is no excuse to lose vast amounts of data. the only excuse for not retaining such data that I can think of is cost. the longer you leave datasets rotting away on old tapes, disks and hard drives, the harder it becomes to salvage and finding people who are experts at retrieving data from old media gets harder and more expensive.

One of the places that I've worked did various sorts of science / engineering type project work. Quarterly backups of filesystems were archived indefinitely. Even if the data was staying online, at the completion of every project an archive was made of the data on a minimum of two pieces of backup media along with various bits of metadata regarding the media and data. The archival copies were tested by restore and diffed before actually going into the archive. Of course they kept examples of the different tape drives, and sometime systems, around to use as needed for quite some time.

Having seen the ugliness of tape drives eating archive media I would be inclined to suggest at least 3 copies.

Re:Precisely (1)

Some types of work generate enormous amounts of data in relatively short periods. The only way to keep things under control is to generate the data and ruthlessly pare back whatever isn't needed, preferably as you go. Big datasets cost real money to keep online, especially when there are many of them. Data that isn't needed for current work isn't helpful and doesn't need to be online, but you may have to bring it back online in the future. People say that disk is cheap, and it is, until it has to be high performance, highly reliable, accessible 24x7 to large user bases for simultaneous use, backed up, secured, and managed. Various forms of hierarchical storage can help but don't eliminate the issues unless your budget is very robust or your data creation is low paced.

That is a very unreasonable assumption.

There are many entities with vested interest to keep the data that supports their point of view, or their profit motive or their meal ticket alive. For example data collected meticulously by a underfunded biology professor about the allotropic speciation of the salamanders around the lake hole-in-the-mud would disappear in a jiffy. But flawed research supporting the efficacy of a patented clot busting drug would be perpetuated. Epidemiological studies showing the adverse side effects of the same drug would be hunted down and eradicated.

History is written by the winners. At least part of the data/research preservation is done people with vested interests preserving it selectively.

Your an AC posting about something not remotely controversial so you're either lazy or lying and I'll take your claim with a pinch of salt on those grounds. I don't think anyone is claiming that keeping the data available is either simple or cheap; but those points don't make it any less important. If the data a paper is based on isn't available then the paper itself loses value because anyone can write a paper showing anything and if they don't need to provide the data then it's much harder to investigate. You are absolutely right that simply having the data available isn't always enough to be able to use it, however we've also seen examples of where dubious or wrong mathematical methods being applied to data in academic research so it's important that information on this is available with the results of the research.

Wow, what a load of patronising bollocks. "My data was so important that I published it in a peer reviewed journal, but nobody else is smart enough to review it.

It's unreasonable to keep the old data indefinitely without a massive public repository

The bound experiment notebook that any undergrad worth anything was taught to keep in the pre-computer era is just as reasonable to demand today. YOU make your living with data, YOU learn how to maintain backups, or use the democratic process in your academic institution to get someone else to do it.

I do absolutely acknowledge that the move away from paper has made this vastly harder. Paper kept in a dry environment takes at least a lifetime to rot, and nearly every adult human in the developed world knows how to read and copy a sheet of paper. Maintaining electronic backup media usually takes far more frequent intervention, and greater expertise - not just with the hardware, but to ensure on-going readability of the data format. This is one of those things where the technologist who are entirely hep with every buzzword of the last 5 years forgets that the world's just slightly longer, and what seems like the only important set of tools in the world today will be a footnote in history tomorrow.

"I'm a researcher and I don't have time or space to keep old data as I'm generating too much new data."

well if that isn't the silliest thing I've ever read. there's no excuse for not retaining data, no matter how large the sets may be. storage in 2013 is incredibly cheap and there's many different systems, with incredible amounts of storage space you could use to back it all up on but I figure this more of a financial reason than your excuse of 'I'm generating too much data' nonsense.

"but the raw data isn't usually very useful to anyone without context or knowledge of subtle and poorly documented technicalities"

I seriously doubt you are a researcher of any kind based on the quote above. It doesn't really matter about the 'context' or 'poorly documented technicalities' as you so elegantly put it. You cannot just assume that if someone were to pick up your data they won't understand the 'context'. that is ridiculous. It's all do with unorganized researchers/institutions and money.

"This just seems like ammunition for the climate change deniers to bitch about."

"climate change deniers". very amusing. if you want your data and research to stand up to scrutiny then keep all your datasets. what have you to hide? are you hiding the fact that you became a climate researcher so can you stick your hand out for free research money while producing data that is laughable?

Wouldn't documenting your experimental method be part of your job? There's really no reason why raw data should be this mysterious entity that nobody can possibly understand unless they were there when it was collected. IMHO, your results -- whatever they are (I only hope it doesn't have anything to do with a drug that physicians might be prescribing to patients) -- are highly questionable if the experiment cannot be reproduced. On the positive side, at least you admit that your documentation efforts were inadequate.

Most of the articles that have scientific papers also have an account in the general media, usually several with varying degrees of utility. Read those instead. They are generally enough to at least engage in discussion at some level on Slashdot.

If you actually need the academic paper, then do one of several things: keep searching the internet, including the authors pages, it may be there or in some less obvious place, or put it on the list to read the next time you go to a research library that has the journal, or pay for it. The fact that you don't read it today doesn't make the information disappear.... at least if you don't wait a couple of decades. It should still be there next week, month, or year.

No, the timespan is 20 years. Within 20 years the results will either be sunk without a trace, disproven or replicated. A fourth option is very unlikely.

For example, I doubt the original measurements of superconductivity are still around. If they are, they'd be interesting from a historical perspective, but you could replicate the results yourself with some fairly standard cryolab equipment. No one's going to doubt superonductivity because the original results have gone.

In most cases I would agree. However there are some large tables of data that are at least that old that are referred to currently. And they have not been replicated since.

Further, the tables are themselves not raw data but modified data with the raw data and methodology no longer available.

that I used for my paper 15 years ago. It is on a tape, that is somewhere in a drawer, that I have no tape drive for. On the other hand, the LaTeX file and the C and FORTRAN programs I used to evaluate and create the data and write the paper are still on a hard drive that is running on a computer in my network and I can access it right now. I probably can*t compile the the program without change (was written for Solaris and DEC machines) and maybe not even run LaTeX on it without getting some of the included styles, but still it is there.
Since my work was in theoretical physics and numerical the loss of the raw data is probably not as bad as long as you still have the software, but I guess for an experimental physicist the problems would be much greater to keep the massive amount of data they sometimes have and if lost to reproduce the data.

Some idiot sub-editor wrote a misleading figure caption here. The article (which I've read) says nothing about how data is lost with age. It only says something about how much data is lost for papers of a given age as of now.

In other words it does not mean that in 10 years time, 10 year old papers will have such drastic data loss. The world 20 years ago was a very different place in terms of communication, scientific practice, and data storage than it was 10 years ago or is now.

The Slashdot article repeats the fallacy by saying "scientific data disappears". No it doesn't. Some has disappeared, but the paper cannot say anything about whether it is still disappearing.

In all seriousness the public needs to keep a few things in mind.
1) Staff move
2) institutions of all types are usually only funded year to year
3) Not all data lost if a bad thing. Depends on subject, depends on findings.
4) Not all data is lost , sometimes it is superseded. This is particularly true in molecular biophysics/bioinformations etc... Ironially, I think climate modelling keeps an archive of their "best guesses"
5) There is too much data - just about every HEP or sequencing or microarray...

Or maybe impossible to regenerate (for certain values of impossible). I remember reading a classified technical report (dating from the 1940s) related to military life-jacket development, wherein the question arose as to whether a particular design would reliably turn an unconscious person face-up in the water. The experimental design used was to dress some servicemen (sailors, possibly, but I don't recall) in the prototype design, anaesthetise them and drop them in a large body of water, checking for face-down floaters to disprove the null hypothesis. Somehow, I don't think that those data are going to be regenerated any time soon. I hope to God not, anyway.

onyxruby (118189) | about 8 months ago | (#45744823)

Before science gets hot and bothered about the loss of data scientists need to do something about the quality of the data they produce to begin with. Frankly given the complete lack of quality controls that a lot of scientists use the loss of their data is probably for the best. Depending on the field as much as 60% of all scientific research cannot even be reproduced. Work that cannot be reproduced by another team is far from isolated to one field either:

http://www.eusci.org.uk/articles/data-doesnt-lie-scientists-do [eusci.org.uk]

Depending on the study that means that either the data has been fabricated by unethical scientists, or the data has been misrepresnted for political purposes. Studies are often improperly interpreted by failing to take into account sound statistical modeling and noise is reported as science. In some fields politics have effectively taken over (e.g. social sciences) and standards are used that would never be tolerated in other scientific fields.

The very culture of science that demands quantity over quality needs to change [columbia.edu] as the rat race that inspires junk science to begin with. I can't think of any other field where those kinds of failure rates about the reproducibility of your work would do anything other than get you fired for fraud and destroy your career. I like science, I have since I was a young child, but the junk were getting labeled as science doesn't deserve the label.

As a former paper industry professional (recycled pulp), Paper is fine except that people limit its use to readable font. That is what led to Microfiche (which is now being dumped by the truckload at recycling stations as "obsolete tech"). If you printed a hard copy of everything either to microfiche or extremely small 1-point font, you could store the data in a type of seedbank or gene bank.

A salt mine may not be appropriate, but I'd like to start a business where everyone could send their hard drives to a giant 100 year Time Capsule Vault in the Sonoran desert. We are shredding retired professors hard drives which the professors probably would prefer to see preserved. The "half life" of privacy risk is different for different data... experiments, emails, credit card numbers, and porn browsing cookies are not posing the same posthumous risk/benefit. We are cremating too many of our future fossils.

IMHO the biggest threat to raw data is misplaced or randomized fear of privacy combined with copyright planned obsolescence (or mandated "e-waste" shredding for working tech, out of fear that poor people will misuse a display device). Certain data does need to be destroyed, and certain papers shredded. Treating all "data" as having the same expiration date has something to do with the loss of the data in the article.

A handy chronology of the history of data retention:

[2500BC] King Fuckemup boldly slew the enemy and I, Scribe Asskissus hath inscribed it in stone. He is an asshole who owes me back wages."
[1500] "With quivering quill [wikipedia.org] I will write mine own data."
[1866] "Data published at great expense into leather-bound volumes. Dust sold separately."

[2005] "I'll just email it to myself and shut the computer off immediately, then pick it up at work."
[2009] "Yes, three copies! In the safe. There was a fire. Yes, inside the safe. It was a fireproof safe, so no one noticed."

[2500] "King Grapeape slew the primitive humans and buried their statue on the beach. I, Scribe Anthopoapologus hath incribed it in stone."

Perhaps the most mystiying data retention escapade of Modern Times [youtube.com] is the missing Apollo 11 SSTV moon tapes [wikipedia.org] which contained a multiplexed stream of raw telemetry and the original slow-scan TV signal broadcast from the moon. Not 'missing' really, rather we know they were re-used and recorded over because everyone assumed it was someone else's job to ensure that at least one copy was in a safe place. While the earth station operators dutifully sent their tapes to NASA where the sharpest signal of the moon landing was sure to be perserved for posterity (not), fortunately there were some librarians on duty, and you can aquire DVDs of the moonwalk [honeysucklecreek.net] with better quality than the recordings you've seen in countless movies -- an 8mm film camera pointed at an original SSTV monitor at Honeysuckle Creek, and the best quality scan-converted version.

In the Foundation series, Asimov envisioned Gaia [wikipedia.org] , a world in which a telepathic network of sentient (and sensuous) beings kept a 'working set' retrievable data in-memory -- but also via access to progressively less and non-sentient objects, such as plants and even rocks -- a vast archive. Ask the mountain, it will answer in time, a long time.

Our own Earth has a Gaia storage mechanism, a record of its magnetic field over geologic time stored as polarization in crystallized lava floes [youtube.com] . But it is not being used for data storage -- actually the magnetic record contains another signal. Scientists have 'played' back 2 billion years of field data and sped up it resolves to a brief, scratchy desperate voice recording: "Help! I am being held prisoner in a planet factory!"

But what of modern unstructured swarm memory? Look at these stats of torrent retention [torrentfreak.com] . You will see that the largest number of seeders was 144,663 hosting Season 3 episode 1 of "Heroes". The longest hosted torrent is a ASCII-video version of The Matrix movie [chattanoogastate.edu] .

A valiant attempt to store long term data is the Rosetta Project [rosettaproject.org] . "The Rosetta Disk fits in the palm of your hand, yet it contains over 13,000 pages of information on over 1,500 human languages. The pages are microscopically etched and then electroformed in solid nickel, a process that raises the text very slightly - about 100 nanometers - off of the surface of the disk. Each page is only 400 microns across - about the width of 5 human hairs - and can be read through a microscope at 650X as clearly as you would from print in a book. Individual pages are visible at a much lower magnification of 100X.

The etched nickel Rosetta disks are sure to become a valuable resource for generations in the distant future to discover just what the hell was going on in this age. We sure don't have a clue. Some one will discover one keeping a coffeemaker level and realize that it has tiny writing on it. I zoomed in at random and saw text rendered as a black-n-white bitmap. It is like a sending a fax to the future. It was there I saw inscribed, thus: "Dari, pag nda' Tuhan, kamahapan na ya ni inaa si' sikamimon. Pag bay pingka' sangom, pag taabut sayu, ilooy na nika-mpat ngallaw na. Pag-anu, mahpalman na baw Tuhan, yuk na, "Subay situ meka jinisan..." Which explains everything.

Goldsmith (561202) | about 8 months ago | (#45745567)

Our scientific research system is built around the process of joining a lab, mastering the work there, and then leaving. There are very few long term research partnerships. The people who stay in place are the professors, who generally do not do the research work.

So you join a lab, produce a few terabytes of data a year, pull a few publishable nuggets out of that and then leave. I have a few backup hard drives that move around with me with what I consider my most important data, probably total 1/10 of the data I have taken. After a few years, this data is really unimportant to me as the labs I have left have done a good job of continuing the research and I have to spend my time and money on something else.

The original data is eventually overwritten by researchers a few "generations" removed from me and that's the end of it.

Submission Text Formatting Tips

We support a small subset of HTML, namely these tags:

  • b
  • i
  • p
  • br
  • a
  • ol
  • ul
  • li
  • dl
  • dt
  • dd
  • em
  • strong
  • tt
  • blockquote
  • div
  • quote
  • ecode

"ecode" can be used for code snippets, for example:

<ecode>    while(1) { do_something(); } </ecode>
