Geologic Column: Beer's secret ingredient: geology

Geologists have a long history with beer. Earlier this year, I decided to raise my own beer appreciation to the next level and take a class on the subject. I attended the beer school at the Anheuser-Busch Brewery in St. Louis. A few minutes into the class, our instructor noted that the beer-brewing process uses clean water, which, he said, is basically the same no matter where you are. Unfortunately, that got us off on the wrong foot.

Bare Earth Elements: AGU 2013 wrap-up

It’s back to the office this week for several EARTH staffers, including myself, who attended the annual meeting of the American Geophysical Union in San Francisco last week in search of interesting story ideas and fascinating folks in geosciences that we might cover in upcoming issues. With more than 20,000 participants, 7,000 research talks and invited speeches, and 14,000 posters, along with numerous other activities, there was plenty of potential material, and we spent some long days absorbing as much we could. For now, here are a few highlights of AGU 2013.

Bare Earth Elements: IceCube observatory spurs "dawn of new age" in astronomy

The main purpose of the world’s largest neutrino observatory — the $270-million IceCube project — is to detect and hopefully identify the as-yet-only-theorized sources of exceptionally high-energy subatomic neutrinos that stream through space. In a new study, the members of the project, comprising about 250 scientists, laid out their case showing that the first of those goals — detection — has been accomplished. They detailed 28 detection events of neutrinos ranging in energy from about 30 tera-electronvolts (TeV) to 1.14 peta-electronvolts (PeV) — far higher than for any neutrinos previously observed — and suspected of having originated outside the solar system in violent phenomena like quasars and gamma ray bursts.

World War G: Zombies, energy and the geosciences

In lieu of doing a "year in review" issue this year, EARTH asked our staff and some frequent contributors to write a short commentary on something that grabbed their attention in 2013. We gave everyone carte blanche. What follows is a collection of extremely varied, often very personal insights into how the planet impacted each individual. In this commentary, EARTH contributing editor Michael Webber draws parallels between zombies and the geosciences.

Tackling "Boundary Faults" across the Alaska-Yukon border: A report from the field

Our two dusty trucks roll across the airstrip, casting long, late-May shadows down the runway. We spot our colleagues from the Yukon Geological Survey and realize we’ve found the right place after an exhausting 12-hour drive from Anchorage punctuated by several U-turns to find the right unmarked access driveway off the Alaska Highway at the south end of Kluane Lake. The evening air is crisp, and the towering peaks to the south are capped with snow.

Energy 360: Leaving our corners for the radical middle: New Zealand sets an example

Energy underpins every aspect of modern life, yet it is often a source of conflict in society. Thus, considering the political ramifications of energy policies is both inevitable and important. But separating politics from science and economics can be difficult, in part because everyone, including me, has biases. Bias in and of itself is not bad; some might even consider it an unavoidable byproduct of knowledge (or the lack thereof). The challenge with energy policy discussions is to manage bias and potential conflicts of interest and conscience.

Bare Earth Elements: Rim Fire Roundup

The devasting Rim Fire has been torching a growing patch of California for the last week and a half. The latest update from Cal Fire reports that the fire has burned about 726 square kilometers (~179,000 acres), currently making it the 7th largest fire by burn area in the state's history. EARTH offers a roundup of sites where official information can be found, as well as some of the many recent news reports covering the fire.

Geologic Column: Assessing energy and mining workforce needs

In his 1971 book, “Encounters with the Archdruid,” John McPhee quoted Charles Park, an economic geologist who worked at the U.S. Geological Survey and then Stanford University, who said, “People seldom stop to think that all these things — planes in the air, cars on the road, Sierra Club cups — once, somewhere, were rock. Our whole economy — our way of doing things, most of what we have, even our culture — rests on these things.” Although McPhee’s emphasis was on the balance between environmental protection and our societal need for raw materials, the book highlighted the fundamental importance of energy exploration and mining, an idea that implies still another significant message: Our society needs scientists, engineers and skilled laborers who can locate and extract raw materials and energy sources from the rocks beneath our feet in order to power our economy and our way of life.

Blogging on EARTH: A letter from field camp

Bryce Mitsunaga, a recent graduate of Williams College in Williamstown, Mass., is currently attending field camp at the Yellowstone-Bighorn Research Association camp located in the Beartooth Mountain Range outside of Red Lodge, Mont. In honor of EARTH's August feature on field camps, Bryce wrote in with some reflections on his experiences so far.

Bare Earth Elements: The field camp experience in photos

For the August issue of EARTH, I wrote about some of the ways in which geology's longstanding rite of passage — field camp — has changed over the years, as well as how it has remained the same.
