Down to Earth With: Geologist and paleontologist David Wilcots

When David Wilcots was 4 years old, his parents took him to the American Museum of Natural History in New York City where he encountered his first giant dinosaur skeleton: a roughly 27-meter-long sauropod named Apatosaurus (though at the time it was still popularly known as Brontosaurus). “That just blew my mind,” he remembers. His passion for paleontology grew, branching from dinosaurs into early mammals, and led him to major in geology at Temple University in Philadelphia. In 1988, he earned a master’s in geology at Fort Hays State University in Kansas. But then, things didn’t go as planned. “When I got out of grad school, I looked for jobs in paleo, but couldn’t find any,” he recalls. “Environmental geology was the next best thing.” He began consulting with business and government agencies, and as time went on, his second choice of career grew on him.

Geomedia: Books: "Quakeland" spotlights seismic risk

I was flying to Seattle when I finished Kathryn Miles’ 2017 book, “Quakeland: On the Road to America’s Next Devastating Earthquake.” I shut the book with a shudder of dread. There’s trouble brewing below the myriad coffee shops, not just in Seattle, but also across the Pacific Northwest. Seattle and the surrounding region sit atop the Cascadia Subduction Zone (CSZ), where the diminutive Juan de Fuca Plate dives eastward beneath the sizable North American Plate, producing a chain of stratovolcanoes arrayed along the coast like pearls on a string — an explosive geohazard.

Benchmarks: May 3, 2003: New Hampshire's Old Man of the Mountain falls

On May 2, 2003, the Old Man of the Mountain, New Hampshire’s famous face-shaped granite formation, adorned the side of Cannon Mountain in Franconia Notch State Park, just as it had for millennia. But by the next morning, it was gone: The iconic stone face had fallen.

Geomedia: Books: Solar eclipses past, present and future

The two books reviewed here — “Totality” and “American Eclipse: A Nation’s Epic Race to Catch the Shadow of the Moon and Win the Glory of the World” by Colorado science writer David Baron — both capture the historical scientific significance and the excitement that still exists today in viewing solar eclipses, particularly those that pass over our own piece of the planet.

Mineral Resource of the Month: Sulfur

Sulfur is one of the few elements found in elemental form in nature and has been used in elemental form since ancient times. It forms near volcanic vents and fumaroles, and small quantities of native sulfur form during the weathering of sulfate and sulfide minerals. However, the largest concentrations of sulfur are found associated with sulfide ore mineral deposits and with evaporative minerals in salt domes. As the 16th-most abundant element in Earth’s crust, sulfur is plentiful and can be found around the world.

Geomedia: Television: "One Strange Rock" is Superlative

National Geographic's new 10-part documentary series, "One Strange Rock," is, in a word, superlative, according to our reviewer. Featuring gorgeous footage and state-of-the-art, digitally generated animations, and perhaps covering a wider range of earth science topics than other documentaries in the genre, it’s worthy of the adjective.

Benchmarks: April 4, 2011: Air France Flight 447 wreckage found using modern oceanography tools

In the early morning hours of March 8, 2014, Malaysia Airlines flight 370 (MH370), en route from Kuala Lumpur to Beijing, lost communication with air traffic control during the transition between Malaysian and Vietnamese air space. It then disappeared, along with all 239 people aboard.

Down to Earth With: Conservation engineer Emily Pidgeon

“I can be a very blunt object,” says Emily Pidgeon, describing how she moves through the world and how she approaches her work. Her Australian accent, drawling yet punctuated, rises above the din of the lunch crowd at a café. She pauses a moment, and declares herself a larrikin. “Do you know that word, larrikin?” She explains that Australians have a larrikin culture — they’re troublemakers, but in a good way. “We have a healthy disrespect for authority,” she says, sipping her tea.

Benchmarks: March 29, 1912: Scott's South Pole Journey Ends in Death

The epic tale of the race between Norway and Britain to be the first to reach the South Pole — and its tragic conclusion with the deaths of British team members in February and March 1912 — is well known. But the details of what happened on the ice, of what went wrong for the British expedition, have continued to be discussed and debated since the bodies of Capt. Robert Falcon Scott and his four crewmates were discovered the following summer. Several recent studies on the Antarctic climate and on the questionable behavior of Scott’s second-in-command are casting new light on the outcome of the expedition.

Geomedia: On the Web: How will melting ice impact your city?

The relationship between melting glaciers and rising sea levels is best described as: “It’s complicated.” A new online tool shows just how counterintuitive predictions of how melting land-ice will affect coasts can be.
