The California Seafloor Mapping Program is the most extensive of its kind, initiated in 2008 and bearing fruit in a series of beautiful maps.

The CSMP has collected bathymetry (underwater topography) and backscatter data (providing insight into the geologic makeup of the seafloor) that are being turned into habitat and geologic base maps for all of California's State Waters (mean high water line out to three nautical miles). Although the CSMP was originally developed to support the design and monitoring of marine reserves through the Marine Life Protection Act, accurate statewide mapping of the seafloor has also contributed significantly to these efforts

Betsy Mason reports on the sensational underwater geography that the maps reveal. It's not just pretty: it will save lives.

This kind of information is critical because the magnitude of an earthquake is determined by the length of a fault that ruptures. Longer faults are capable of bigger quakes. If two smaller faults that were thought to be separate are actually connected, they could potentially rupture together to cause a bigger earthquake than previously thought. Discoveries of that sort could even change the USGS’s seismic hazard forecast for California.

Uncovering sexual preferences by data-mining sex-toy sales [NSFW]


UK sex-toy retailer Lovehoney allowed researcher Jon Millward to data-mine its huge database of over 1,000,000 sex-toy purchases and 45,000 reviews, in order to see what he could infer about Britons' sexual proclivities from the things they bought.

Tesla's "car-as-service" versus your right to see your data

Espen got a parking ticket for his Tesla, and he's pretty sure he can exonerate himself, if only the company would give him access to his car's data, but they won't.

Fax Your GP: quick opt-out from insane NHS plan to sell your medical records


The UK National Health Service has initiated a plan to take the nation's private health records and sell them off to private companies in a process overseen by notorious multinational bumblewads ATOS. If you live in the UK England, your records -- mental health records, prescriptions, records of surgeries including abortions, and other sensitive personal information -- will be handed over to a wide-ranging group of companies all over the world.

Unless you opt out. And opting out isn't easy. There's no central place to opt out. Instead, you have to send a letter to your GP's surgery, which means you have to look up your GP's surgery's address, compose a legally sufficient letter, print it out, find an envelope and a stamp -- etc.

However! There's a better way. A group of volunteers whom I trust implicitly, including the astounding Stef Magdalinski (who made the Faxyourmp service that is the ancestor of Theyworkforyou) have created Fax Your GP, a dead-simple form that will look up your GP's fax number for you, create a form opt-out letter you can fill in in just a few easy steps, and then they'll fax that letter directly to your GP's surgery. I just opted out.

Toronto mayoral disaster: illegal deletion of staffers' email?

More news from the embattled mayor of Toronto, Rob "Laughable Bumblefuck" Ford: after two of his senior staffers walked out on him following questioning by Toronto homicide detectives, it appears that someone illegally ordered the destruction of their archived city emails and call-records -- as well as the archived electronic communications of Ford's former chief of staff, whom Ford fired under mysterious circumstances.

The Star heard concerns at city hall Wednesday afternoon over the potential destruction or hiding of the records of three staffers who resigned or were fired during the ongoing crack cocaine scandal. Sources told the Star the records were in danger after city employees were directed to delete them.

The Star sent a request late Wednesday to the city asking for email and phone records of the three staffers in question for the time period during which the video at the heart of the scandal has been discussed.

Emails sent by city employees, including political staffers, are automatically preserved by the city, though emails related to “personal” business are exempt from freedom of information requests.

Two people familiar with the system said the emails of specific political staffers cannot be permanently erased from the system.p

Animated graphic of meteorites seen impacting Earth

Bolidessss

Carlo Zapponi created Bolides, a fantastic animated visualization of meteorites that have been seen hitting the Earth. The data source is the Nomenclature Committee of the Meteoritical Society's Meteorite Bulletin. "The word bolide comes from Greek βολίς bolis, which means missile. Astronomers tend to use bolide to identify an exceptionally bright fireball, particularly one that explodes." Bolides

Satellites trace the appearance of crop circles in Saudi Arabia

It's not the work of aliens. Instead, you can chalk these crop circles up to humans + money + time. And, with the help of satellite imaging, you can watch as humans use money to change the desert over the course of almost 30 years.

Landsat is a United States satellite program that's been in operation since 1972. Eight different satellites (three of them still up there and functioning) have gathered images from all over the world for decades. This data is used to help scientists studying agriculture, geology, and forestry. It's also been used for surveillance and disaster relief.

Now, at Google, you can look at images taken from eight different sites between 1984 and 2012 and and watch as people change the face of the planet. In one set of images, you can watch agriculture emerge from the deserts of Saudi Arabia — little green polka-dots of irrigation popping up against a vast swath of tan. In another se, you'll see the deforestation of the Amazon. A third, the growth of Las Vegas. It's a fascinating view of how we shape the world around us, in massive ways, over a relatively short period of time.

Bloomberg publishes CEO-to-employee-pay chart


Alan sez, "Bloomberg got tired of waiting for the SEC to implement its own rule requiring disclosure of data on how many times the median salary the CEO makes for publicly traded companies so they did a little sleuthing of public data and a little averaging math and calculated the ratio for the top 250 of the S&P 500 companies. The data are searchable and sortable and there's space for companies to comment, which quite a few have done. To my surprise Oracle is not #1, though it is the only tech firm in the top 10."

Siri keeps data for "up to two years", but only anonymously

Robert McMillan explains what happens to the data generated and stored with Siri queries: "Once the voice recording is six months old, Apple “disassociates” your user number from the clip, deleting the number from the voice file. But it keeps these disassociated files for up to 18 more months for testing and product improvement purposes." [Wired]

Internet penetration is never correlated with increasing power to dictators, and is often correlated with increased freedom


Philip N Howard wonders if there are any countries that have, on balanced, suffered as a result of the coming of the Internet -- say, because improved networks created so many opportunities for dictators to spy on dissidents that it swamped any free speech/free association benefits that the Internet delivered. So he scatter-plotted PolityIV’s democratization scores from 2002/2011, and cross-referenced them with World Bank/ITU data on internet users. The conclusion: by this method, no country experienced a decline in its overall levels of a democracy as it attained widespread Internet penetration, and almost all many countries experienced a rise in democracy levels that correlated to a rise in Internet penetration.

Are there any countries with high internet diffusion rates, where the regime got more authoritarian? The countries that would satisfy this condition should appear in the top left of the graph. Alas, the only candidates that might satisfy these two conditions are Iran, Fiji, and Venezuela. Over the last decade, the regimes governing these countries have become dramatically more authoritarian. Unfortunately for this claim, their technology diffusion rates are not particularly high.

This was a quick sketch, and much more could be done with this data. Some researchers don’t like the PolityIV scores, and there are plenty of reasons to dislike the internet user numbers. Missing data could be imputed, and there may be more meaningful ways to compare over time. Some countries may have moved in one direction and then changed course, all within the last decade. Some only moved one or two points, and really just became slightly more or less democratic. But I’ve done that work too, without finding the cases Morozov wishes he had.

There are concerning stories of censorship and surveillance coming from many countries. Have the stories added up to dramatic authoritarian tendencies, or do they cancel out the benefits of having more and more civic engagement over digital media? Fancier graphic design might help bring home the punchline. There are still no good examples of countries with rapidly growing internet populations and increasingly authoritarian governments.

Are There Countries Whose Situations Worsened with the Arrival of the Internet?

Sloppy statistics: Do 50% of Americans really think married women should be legally obligated to change their names?

Jill Filipovic wrote an opinion column for The Guardian yesterday, arguing against the practice of women taking their husbands' names when they get married. It ended up linked on Jezebel and found its way to my Facebook feed where one particular statistic caught my eye. Filipovic claimed that 50% of Americans think a women should be legally required to take her husband's name.

First, some quick clarification of my biases here. Although I write under a hyphenate, I never have legally changed my name. I've never had a desire to do so. In my private life, I'm just Maggie Koerth and always will be. That said, I personally take issue with the implication at the center of Filipovic's article — that women shouldn't change their names and that to do so makes you a bad feminist. For me, this is one of those personal decisions where I'm like, whatever. Make your own choice. Just because I don't get it doesn't mean you're wrong.

But just like I take objection to being all judgey about personal choices, I also take objection to legally mandating personal choices, and I was kind of blown away by the idea that 50% of my fellow Americans think my last name should be illegal.

So I looked into that statistic. And then I got really annoyed.

Book about big data, predictive behavior, and decision making

Kenneth Cukier was on NPR this morning talking about the new book he wrote with Viktor Mayer-Schonberger, "Big Data: A Revolution That Will Transform How We Live, Work and Think." It sounds fascinating and relevant to research I'm doing at Institute for the Future on newfound applications of systems thinking in what we're calling the "coming age of networked matter." Here are some choice bits from the interview:
NewImageOn how Target identifies pregnant customers

"The example comes from Charles Duhigg, who's a reporter at The New York Times, and he's the one who uncovered the story. What Target was doing was they were trying to find out what customers were likely to be pregnant or not. So what they were able to do was to look at all the different things that couples were buying prior to the pregnancy — such as vitamins at one point, unscented lotion at another point, lots of hand towels at another point — and with that, make a prediction, score the likelihood that this person was pregnant, so that they could then send coupons to the people involved... there might be a coupon for a stroller or for diapers ...

On how Google tracks the flu

"Google stores all of its searches. What they were able to do was go through the database of previous searches to identify what was the likely predictor that there was going to be a flu outbreak in certain regions of America. Now, keep in mind, we pay for the [Centers for Disease Control and Prevention] to look at the United States and find out where flu outbreaks are taking place for the seasonal flu. But the difference is that it takes the CDC about two weeks to report the data. Google does it in real time simply on search queries."
