We live in a time of strange contradictions: Many of us carry around highly sophisticated, GPS- and camera-equipped supercomputers just to play 2048 on the bus, while a lot of science is still limited by rudimentary tools and a lack of information. This is especially true for marine sciences (perhaps in part because water and electronics don’t always play well together). From Wired:

“It’s crazy how behind the times we are,” says Sly Lee, a former biological science technician for the US National Park Service and founder of the Hydrous, a science communication non-profit. “We can decode coral genomes, but we can’t accurately track how fast the corals are degrading.”

Part of the problem with keeping track of coral degradation is that we lack a good yardstick — how do you measure the size of an irregularly shaped, many-branched staghorn colony? How do you track the exact hue from healthy to bleached? At the moment, it usually involves a literal yardstick — scuba diving scientists use measuring tapes to survey huge patches of irregular coral.

So Lee is testing a new way to map individual coral colonies by their size, color, and texture, and create 3D models that scientists can examine cheaply in a lab. Last winter, Lee went to the Maldives — site of a recent large bleaching event — to test his new tool:

Lee dove with a waterproof camera to take nearly 200,000 images of the reefs from every angle. Then he uploaded the photos to Autodesk rendering software, stitching them together into a high-resolution model. Later this year, he’ll return to the same corals, then use the before-and-after visualizations to see exactly how they have fared.

Here’s a video of one table coral modeled in Lee’s software:

Once the software is online and openly accessible, anyone should be able to upload their coral footage to the system. So hello, waterproof casing, goodbye, guestimation.

This Major Newspaper Just Declared War on Fossil Fuels

Inside the Guardian’s decision to embrace climate activism. Jonathan Nicholson/ZUMA After 20 years at the helm of one of the United Kingdom’s most influential newspapers, Alan Rusbridger is about to step down as editor of the Guardian. He’s not going quietly: In an op-ed a couple weeks ago, Rusbridger pledged to use his waning weeks to launch a full-out war on climate change: So, in the time left to me as editor, I thought I would try to harness the Guardian’s best resources to describe what is happening…For the purposes of our coming coverage, we will assume that the scientific consensus about man-made climate change and its likely effects is overwhelming. We will leave the sceptics and deniers to waste their time challenging the science. The mainstream argument has moved on to the politics and economics… We will look at who is getting the subsidies and who is doing the lobbying. We will name the worst polluters and find out who still funds them. We will urge enlightened trusts, investment specialists, universities, pension funds and businesses to take their money away from the companies posing the biggest risk to us. And, because people are rightly bound to ask, we will report on how the Guardian Media Group itself is getting to grips with the issues. The Guardian, a Climate Desk partner, is no stranger to global warming reporting. It was the first daily paper in the UK to institute a dedicated section for environment coverage. The paper has extensively covered international climate negotiations, fracking on both sides of the Atlantic, and the latest climate science, while also pouring resources into lush interactive web features. But its new initiative promises to go even further. The series kicked off with a pair of excerpts from Harvard science historian Naomi Klein’s recent book on the tension between capitalism and the climate crisis. Over the next few months it will include investigative features, daily news stories, videos and podcasts, and even original artwork and poetry. The pieces will appear not just on the paper’s environment pages, but across all sections, from business and tech to lifestyle and the arts. The overarching idea is that from now until Rusbridger’s departure in June, any climate story that any reporter has had kicking around but has never had time to tackle will get priority treatment. But the centerpiece is all about the penultimate sentence in the excerpt above: “We will urge…” This week the Guardian kicked off a petition calling on the world’s two largest charitable organizations, the Gates Foundation and the Wellcome Trust, to divest their financial holdings from the world’s 200 top fossil fuel companies. As of Thursday afternoon, the petition had gathered over 94,000 signatures and earned the support of the country’s energy minister. If that sounds a lot like straight-up activism, that’s because it is. Rusbridger proposed the petition a few months ago at a meeting that included a who’s-who of the paper’s top editors, designers, and website coders, said James Randerson, an assistant national news editor who handles climate reporting. “There were some voices who questioned whether a campaign was the best use of the Guardian‘s voice,” Randerson said, “because the Guardian is about reporting and uncovering things that people can use in advancing an agenda.” But Rusbridger’s argument, Randerson said, was: “We’ve tried to do that for quite a while, and we needed to do something that had a bit more cut-through. We felt that it was time to take that step.” The idea of a newspaper undertaking an openly activist campaign straight from the playbook of Greenpeace or the Sierra Club might seem strange to American audiences, who are accustomed to news outlets at least purporting to adhere to some degree of journalistic objectivity. But in the UK, newspapers taking a step across the line between news and activism is, well, less newsworthy. In 2014 the Guardian waged a similar campaign against female genital mutilation. Prior to the 2009 UN climate summit in Copenhagen, the Guardian convinced 56 newspapers from around the globe to publish a front-page editorial calling for climate action. Randerson also characterized the paper’s extensive reporting on Edward Snowden and the National Security Agency as a kind of unofficial campaign against state surveillance. And the Times of London has an ongoing campaign to promote safety for urban cyclists, inspired by an accident that nearly killed one of its reporters. Randerson said the campaign won’t dampen the editorial rigor applied to reporting, editing, and fact-checking news stories. Is it time for the Washington Post and the New York Times to launch climate petitions of their own? Randerson wouldn’t say, but he did argue that especially in the United States, “the media have not done a service to their readers in explaining what’s really at stake here.” Now we get a chance to see if a more direct approach does the trick.
