After constructing water vessels using the methods of prehistoric people who lived on the Channel Islands, researchers found that their 5,000-year-old manufacturing process polluted the air with chemicals that the Environmental Protection Agency classifies as dangerous. The findings, published Friday in the journal Environmental Health, demonstrate that human exposure to harmful chemicals is nothing new.
Elected officials from both parties have supported an earthquake early warning system for the West Coast that, after years of work, was scheduled to begin its first limited public operation next year. … One of the system’s biggest proponents is a Republican congressman who has an influential role in shaping the budget of the U.S. Geological Survey.
When it comes to managing water in uncertain times, few things are more important than knowing how much is flowing in the river alongside your city, or filling the reservoir that irrigates local farms. … But this basic information is at risk across the West because the nation lacks a reliable funding source for the simple stream gages that measure river flows.
Darkness doesn’t usually fall in the middle of the day. So it’s not surprising that throughout history many cultures considered it a bad omen when it did. But as years went by, the terror morphed into intrigue. And nowadays people are booking their travel — months and even years in advance — to experience it.
Experts can’t predict earthquakes, but they can warn you that they’re coming. For a dozen years, West Coast scientists working with the United States Geological Survey have been developing an earthquake early warning system — called ShakeAlert — that could provide anywhere from a few seconds to a few minutes of warning not only about the shaking that’s imminent but also about its intensity.
A significant milestone has been reached in the effort to build a state of the art scientific field station in the Sacramento-San Joaquin Delta. The California Department of Water Resources (DWR) in May finalized the environmental documents for construction of a research hub on the former Rio Vista Army Base.
The wondrous coral reefs of Palau are about to get a health check by scientists from UC San Diego’s Scripps Institution of Oceanography, during a visit partly underwritten by an unusual gift from donors.
The U.S. Geological Survey joins its many partners in other federal agencies, at universities, and in state and local governments in recognizing the importance of the Water Resources Research Act (WRRA) of 1964.
Signed into law 50 years ago by President Lyndon B. Johnson on July 17, 1964, the WRRA established a Water Resources Research Institute in each state and Puerto Rico.
A new global geologic map of Mars –the most thorough representation of the “Red Planet’s” surface – has been published by the U.S. Geological Survey. This map provides a framework for continued scientific investigation of Mars as the long-range target for human space exploration.
Seasonal carbon dioxide frost, not liquid water, is the main driver in forming gullies on Mars today, according to a recent U.S. Geological Survey study that relied on NASA’s Mars Reconnaissance Orbiter’s (MRO) repeated high-resolution observations.
[Jim] Walker and construction crews building a new 220-foot-high dam at Calaveras Reservoir in the remote canyons east of Milpitas have been digging up a prehistoric treasure trove: the teeth of an extinct hippopotamus-like creature called a Desmostylus, clams, barnacles and the giant teeth from a 40-foot-long shark — and what could turn out to be an entire whale skeleton.
“During the last year, whole oceans worth of water have been found in the [Earth's] mantle, hundreds of kilometers below the crust. And a paper in today’s [June 12] issue of Science traces water’s influence all the way down to an important boundary inside the Earth, the top of the lower mantle.”
“California’s drought is imperiling tricolored blackbirds, large trees and native fish, with some of the affected species already on the state’s endangered list and others likely headed there because of rapidly declining numbers, scientists say.”
