New NASA radar satellite maps prepared for the California Department of Water Resources (DWR) show that land continues to sink rapidly in certain areas of the San Joaquin Valley, putting state and federal aqueducts and flood control structures at risk of damage.
Logic might lead you to believe that a mosquito-borne illness like West Nile virus would spread during rainy conditions, as the bugs need water to breed. But a new study demonstrates the opposite is true.
Tommy Williams—a fisheries biologist whose enthusiasm bubbles forth so swiftly, he’s often interrupting himself mid-sentence—is pacing on the banks of the Carmel River. … It’s the thundering flow of a river that has been dammed for the last 94 years—and the sediment (dirt and rocks) that are pushing everything downstream.
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.”
“On her way to visit the Kearney Agricultural Research and Extension Center in Parlier on Monday, University of California President Janet Napolitano got a bird’s eye view of California cropland and rivers dry from the drought — a sight she hopes the universities can help fix through continued research and outreach.”
“By crunching data from the Central Valley, eBird can generate maps showing where virtually every species congregates in the remaining wetlands. … The BirdReturns program, financed by the Nature Conservancy, then pays rice farmers in the birds’ flight path to keep their fields flooded with irrigation water from the Sacramento River as migrating flocks arrive.
From the National Oceanic and Atmospheric Administration (NOAA) National Climatic Data Center (NCDC):
“Drought is a unique climate event, which often begins with subtle effects but can end up being incredibly costly and devastating. Paleoclimatology, or the study of past climate prior to instrumental records, allows scientists not only to collect evidence of past climate conditions, such as drought, but also provides them with a means to investigate the climate processes underlying these conditions.
“Inside a moon of Saturn, beneath its icy veneer and above its rocky core, is a sea of water the size of Lake Superior, scientists announced on Thursday.
“The findings, published in the journal Science, confirm what planetary scientists have suspected about the moon, Enceladus, ever since they were astonished in 2005 by photographs showing geysers of ice crystals shooting out of its south pole.”
