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.

Fieldwork among the pixels: Virtual and augmented reality diversify geoscience education

Students going out into the field to gain hands-on experience and mapping skills is a time-honored tradition in geology. Now, teachers are using virtual and augmented reality technology to bring the field to the students.

Battery recycling underlies elevated lead in African soils

Of all the recycling industries in the world, lead-acid battery recycling is one of the most profitable — and one of the most toxic. In the U.S., regulations on the industry have dramatically reduced lead exposure and pollution at battery recycling plants. But in Africa, where the industry is growing and largely unregulated, lead levels are skyrocketing. A new study in Environmental Research looking at environmental lead levels in seven African countries is shining a spotlight on the ongoing public health crisis.

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.

Measuring earthquakes using fiber-optic cables

Fiber-optic cables crisscross the world, ferrying digital data and enabling internet access and telecommunication. In a new study, published in Geophysical Research Letters, researchers tested whether fiber-optic cables can also be used to detect and measure earthquakes.

Geomedia: Books: Putting 'Seeds on Ice' to protect crop diversity

Tucked away, deep underground, in a frozen corner of the Scandinavian north is the safety net for our food supply. The Global Seed Vault, on the island of Spitsbergen in Norway’s Svalbard Archipelago and popularly known as the “doomsday vault,” shelters our most precious seeds from possible global catastrophe.

Stable isotopes offer novel methods of disease detection

Stable isotope techniques developed by geoscientists are being applied to studies of human health, and one in particular has shown promise as an improved way to determine bone loss, a problem for astronauts, as well as those on bed rest and aging populations here on Earth.

From space to village: NASA's SERVIR program brings a big picture to local communities

Established in 2005, the joint NASA and U.S. Agency for International Development program SERVIR (named for the Spanish verb “to serve”) puts geospatial satellite images and analysis tools into the hands of local decision-makers around the world to help them deal with natural disasters and plan for changing climates.

In the lab, machine learning improves quake forecasts

The U.S. Geological Survey estimates that about 500,000 detectable earthquakes occur worldwide every year. But accurate forecasts of when quakes will occur have long been out of reach, in large part because of the complexities of fault behavior.

Comment: Making the first (and last) geoscience class count

An introductory geoscience course may be the only earth science class many people ever take, and the only chance geoscientists have to help students develop the scientific understanding they will need to make decisions about the grand challenges humanity will face in the future.
