N.E.O.N.: Studying critical ecological issues on a continental scale

NEON, the National Ecological Observatory Network, is one of the most extensive ecology projects ever undertaken. Program scientists — along with members of the public — will examine critical ecological issues across North America, including the effects of climate change, invasive species, droughts, fires and floods.

Down to Earth With: The Lava Cap Winery

During a long career at the U.S. Geological Survey  (USGS) and the University of California at Berkeley, paleontologist David Jones, who died in 2007, made fundamental contributions to understanding the geologic history of western North America, particularly the evolution of California’s puzzling Coast Ranges.

Releasing a flood of controversy on the Colorado River

Since the completion of the Glen Canyon Dam in 1963, the once warm and muddy Colorado River has run clear and cold, with a drastically altered ecosystem. A new plan to release regular, intentional floods — to resupply sediment and restore species habitat — aims to reverse the damage done to the Grand Canyon’s natural systems over the last 50 years.

USArray: Geoscientists' "Earth Telescope"

Big science often requires big tools. Particle physicists use huge particle accelerators. Astronomers need enormous telescopes to peer to the edge of the cosmos. Earth scientists, by contrast, normally probe the planet individually or in small groups using comparatively inexpensive instruments. This “small science” approach has served us well; using it, we have learned a great deal about how Earth works. But now, we have our own big science tool: USArray, a "telescope" for earth scientists to peer deep into the subsurface.

Bigfoot education and outreach

USArray has offered an unprecedented opportunity for earth scientists to explain to the public how we conduct experiments and test hypotheses, and what we aim to learn from the results.

Down to Earth With: Bruce Benson

In a remarkable career spanning nearly 50 years, Bruce Benson has held just two jobs. In 1965, a year after earning his bachelor’s degree in geology, he founded the Benson Mineral Group, an oil and gas exploration and production company that he has owned and chaired ever since. From this foundation, Benson’s business interests have spread into salvaging, banking, mortgage servicing, cable television, geothermal power, real estate and even pizza.

Down to Earth With: Geomorphologist Gregory Tucker

As an undergraduate anthropology student, Gregory Tucker thought math was a boring subject with abstract rules that didn’t relate to his life. Today, that “boring” subject provides the foundation for Tucker’s innovative research involving numerical modeling and unique field studies that recently earned him the European Geosciences Union’s 2012 Ralph Alger Bagnold Medal, one of the highest prizes in geomorphology.

Ecosystem collapse in Pleistocene Australia

Between 50,000 and 45,000 years ago, in the Late Quaternary, Australia suffered a major loss of its megafauna. Sixty taxa of mammals, predominantly large leaf- and twig-eating animals called browsers, went extinct, including all 19 species exceeding 100 kilograms, like the half-ton Palorchestes azael, a marsupial similar to a ground sloth, and the rhinoceros-sized Diprotodon.
