Finding a definition and purpose for sensor journalism at the Tow Center

Before I left for the Tow Center's sensor journalism workshop at Columbia University last weekend, my wife and I hosted some friends for a spinach lasagna dinner. On the stack of books my wife was researching for her dissertation on toxins in science fiction, sat my latest obsession, the DustDuino sensor node.

While we ate, the node's tiny LED lights blinked away as it took particulate matter readings every 30 seconds. A friend pointed out the interesting juxtaposition of the pollution monitor siting on a copy of Rachel Carson's Silent Spring. Our friend's husband, an entomologist, asked what it was all about.

"Part of the idea is to have people make these all over the country, especially places with bad air," I said.

"Interesting," he said. "You know... that doesn't sound much like journalism," he said. "It sounds like research."

I thought about it for a moment, and took a sip of the lemon-and-bourbon cocktail my wife prepared. I didn't have a good answer.

"Journalists are kind of unemployed at the moment, so we're looking for other things to do," I replied.

For me at least, the Tow Center's workshop helped find an answer to that question, and provide a deffinition and goal for sensor journalism. About 50 folks with backgrounds in journalism, science, architecture, community informatics, and computer technology came to the Tow Center's first sensor journalism workshop on June 1-2.

I owe a big debt to the organizers of this event: Emily Bell, the Tow Center director; Fergus Pitt, Tow research fellow; Taylor Owen, Tow research director; along with Laura Kurgan, director of the spatial design lab at Columbia; and Chris Van Der Walt and Sara Jayne Farmer of Change Assembly, Inc.

DustDuino: A plan to crowdsource environmental reporting with low-cost dust sensors

There's some good news in the air. Or, well, about the air.

Last month, the American Lung Association released its 2013 report on the quality of the nation's air. The Lung Association's "State of the Air" report shows the country's air is continuing to improve.

The Lung Association attributes healthier air as a "direct result of emissions reductions from the transition to cleaner diesel fuels and engines and coal-fired power plants, especially in the eastern United States."

That much is good. But there's much room for improvement.

According to the report, "Of the 25 cities with the worst problem with spikes in particle pollution, fourteen had more days or worse problems in 2009-2011 than in the previous report." Six cities included in the report had their worst year ever (over the 14 years the report has been made) for short-term spikes in particulates.

Chicago, home to some of the dirtiest coal-fired power plants in the nation, continued to flunk both daily and annual levels of particulate pollution. This was where I did my own environmental investigation on how the Fisk coal-fired power plant threatened the health of the Pilsen neighborhood (see: "Battle in the Barrio").

The Fisk station dumped 755 tons of particulates into the air on an annual basis, according to a pollution report from the Environmental Protection Agency. The Clean Air Task Force found that the plant contributed to 15 deaths and 23 heart attacks annually, a figure based on EPA data.

The residents of Pilsen eventually won their battle, and the Fisk station was closed. EPA tests after the plant closure showed the particulate and radiation levels had returned to city-wide norms. Interestingly, one of the EPA air quality monitors was mounted in a baby stroller to measure levels around the perimeter of the plant.

Pilsen didn't have air quality monitors to begin with, though. Its residents had to lobby the Illinois EPA before the state placed an air monitor atop an elementary school in the neighborhood. The readings from the monitor led the IEPA to declare Pilsen a "nonattainment" zone for lead, a particulate which impairs the IQ, learning capabilities, and memory of children.

Columbia's Tow Center is brainstorming sensor journalism prospects in workshop

In a little over a week, the Tow Center for Digital Journalism at Columbia University will be organizing experts across multiple disciplines, from around the country, to come up with low-cost, widely-distributable solutions for sensor journalism.

For their Sensor Journalism Weekend (June 1-2), the Tow Center will host discussions on the "pre-history, current practice and opportunities for sensors in journalism," in anticipation of a pilot sensor journalism project to be conducted over the summer.

According to Tow's calendar, there will be "technical, ethical, theoretical and practical resources available, demonstrations of current sensing equipment and opportunities to expand links throughout the community of people working in the field." Folks from the Spatial Information Design Laboratory in the Graduate School of Architecture, Planning and Preservation at Columbia University will be in attendance.
