Geoscientists Without Borders: Geologists Lend a Hand

Craig Beasley’s one-year term as president of the Society for Exploration Geophysicists had a challenging start. After about two months in office, a magnitude-9-plus earthquake struck off the coast of Sumatra on Dec. 26, 2004, triggering a powerful tsunami that killed more than 225,000 people and left hundreds of thousands homeless.

SEG members wanted to help, but did not know how to contribute their expertise. “I could encourage members to donate money and time, but how does that distinguish a contribution from SEG from what people would normally do?” Beasley says.

Mining for iron oxides in coal mine sludge

The billions of tons of coal that miners extracted from Pennsylvania’s ground over the past two centuries have long gone up in smoke, but their legacy lives on in the state’s rivers and waterways. Nasty discharge — often with sky-high metal concentrations — from thousands of abandoned coal mines has been polluting Pennsylvania’s streams and groundwater.

Travels in Geology: Exploring Lake Baikal, the Sacred Sea

Deepest. Oldest. Most biologically diverse. Siberia’s superlative-laden Lake Baikal is one of the planet’s great geological treasures. Located 4,200 kilometers east of Moscow and 2,100 kilometers west of Vladivostok, the lake known locally as the Sacred Sea is like no other.

Benchmarks: April 26, 1986: Nuclear explosion at Chernobyl

By Carolyn Gramling

A rusting Ferris wheel dominates the skyline of Prypiat, Ukraine’s ghost town. A few kilometers away, within a massive concrete structure called the Sarcophagus, are the remnants of the worst nuclear disaster in history: the ruins of the Chernobyl Nuclear Power Plant’s reactor number four — and about 200 tons of highly radioactive material.

Seal missing link found in the Arctic

A newly discovered web-footed mammal may be a “missing link” between land-based and marine pinnipeds, a group that includes seals, walruses and sea lions. The find, occurring on the 150th anniversary of Charles Darwin’s "On the Origin of Species," may shed new light on the land-to-sea animal evolutionary theory.

Down to Earth With: Michael Novacek

When it comes to fossil hunting, Michael Novacek has just about seen it all. As a paleontologist, senior vice president and provost of science at the American Museum of Natural History in New York City, Novacek has braved everything from Andean snowstorms to Yemeni bandits in his quest for fossils. Somewhere, he found time to write two books about his expeditions: “Dinosaurs of the Flaming Cliffs” (1996) and “Time Traveler” (2002). Novacek recently chatted with EARTH reporter Brian Fisher Johnson about his experiences.

Lack of water threatens "Garden of Eden"

Since the downfall of Saddam Hussein in 2003, Iraqis and scientists from around the world have been working hard to restore Iraq’s once-lush marshes. But after several years of measurable improvement, drought and competition over limited water supplies threaten to reverse this progress. Those working on the marshes are confident that the marshes can come back — but whether the people who rely on these wetlands for their livelihood will be as resilient remains to be seen.
