The melding of computer-generated imagery and good old-fashioned scientific research by two Marin residents has helped forge a vivid new production examining coral reefs that opens Friday at the California Academy of Sciences.
Atmospheric rivers are vital to western water supplies, yet until very recently they were poorly understood: difficult to predict and measure, and very hard for scientists to estimate where they would make landfall. … Now a new study by scientists at Colorado State University in Fort Collins has revealed a way to predict atmospheric river storms as much as five weeks in advance.
Water is a valuable resource that affects nearly all aspects of life on earth. It also is limited, so people use a variety of methods to ensure that supply meets demand. One such technique is cloud seeding – adding particles to the atmosphere to promote formation of rain or snow.
U.S. scientists knew little about the impact of uranium mining in the Grand Canyon region before an Obama-era decision shut down new mining claims. Uranium first was discovered near the national park in the late 1940s and has been subject to boom-and-bust cycles.
Just how bad was California’s last drought? For most of Southern California, it was either the worst or second worst since the century Columbus landed in the New World, the Ottoman empire was started and Joan of Arc was burned at the stake.
While the orcas of Puget Sound are sliding toward extinction, orcas farther north have been expanding their numbers. Their burgeoning hunger for big fish may be causing the killer whales’ main prey, Chinook salmon, to shrink up and down the West Coast.
There’s no doubt members of the State Water Resources Control Board don’t want to hear another word about their water grab from farmers, elected leaders, economists, irrigation districts or especially newspaper columnists. But how about some of the state’s most respected scientists? How about the “Delta Watermaster”?
U.S. scientists studying the effects of uranium mining around the Grand Canyon say they are lacking information on whether the radioactive element is hurting plants, animals and a water source for more than 30 million people. And they would not get to fully gather it if President Donald Trump’s 2019 budget proposal is approved.
Frank Gehrke trudges through snow and ice, as he’s done for nearly four decades in the Sierra Nevada. He’s one of many state workers who takes monthly snow surveys, in the same spots, to figure out how much water is in the snowpack. And this old-fashioned way of measuring the snowpack is quite laborsome.
If you imagine the San Francisco Bay as a bathtub, sea level rise means the bathwater is rising. A new study published today in Science Advances finds the tub is sinking too, and in some places, more than others.
Alaskan fishing guide Jason Lesmeister stopped fishing for Chinook salmon more than a decade ago. The population, he said, “plummeted” on the Kenai River, his main fishing ground and a watershed renowned for producing enormous Chinooks, also called king salmon. But the fish aren’t just less abundant today. They’re also noticeably smaller.
The head of U.S. EPA’s Scientific Advisory Board today said he wasn’t sure if man-made emissions of greenhouse gases were causing climate change. “I really don’t know,” SAB Chairman Michael Honeycutt told E&E News. “I haven’t studied that,” he said along the sidelines of the American Chemistry Council’s GlobalChem conference.
Bureau of Reclamation Commissioner Brenda Burman announced that five private sector and citizen solvers shared a prize competition purse of $50,000 for their submissions of concepts to improve arsenic measurement technologies in water. “Current analytical methods are suitable for ensuring regulatory compliance, but there remains a need for rapid, low-cost monitoring of arsenic,” Commissioner Burman said.
The candidate forum at Scholz Garten, a stone’s throw from the Texas State Capitol, was organized by 350.org, a liberal group focused on climate change. So there was little doubt what answer the moderator was seeking when he asked about support for “a complete nationwide fracking ban.”
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.
