The federal government—through the Canadian Space Agency (CSA)—will invest in Canadian innovation that will play a key role in the first-ever global survey of surface water. Kevin Sorenson, minister of state (finance), and MP Michael Chong made the announcement on Aug. 18 on behalf of James Moore, minister of industry.Read More »22-8-14 Government of Canada to Invest in Mapping System for First-Ever Global Surface Water Survey
he severe drought gripping the western United States in recent years is changing the landscape well beyond localized effects of water restrictions and browning lawns. Scientists at Scripps Institution of Oceanography at UC San Diego have now discovered that the growing, broad-scale loss of water is causing the entire western U.S. to rise up like an uncoiled spring.Read More »22-8-14 Severe drought is causing the western US to rise like a spring uncoiling
On a cold and dry December Friday, Zach Hauser is getting ready for a weekend of hunting. The next morning at about 4 a.m., he and a handful of friends will make a nearly three-hour uphill trek into the Arizona woods. There they will tread quietly looking for elk and whitetail deer. On occasion, they come across a mountain lion.
They will probably return late the same night, but “if we get something, we might stay the night and sleep on the ground,” Hauser says. “It’s better to carry it back in the morning.”
Extensive groundwater pumping is causing a huge swath of central California to sink, in some spots at an alarming rate, the U.S. Geological Survey reports.
With California in the throes of a major drought and demand for groundwater rising, officials and landowners are racing to respond to the process known as subsidence. Some areas of the San Joaquin Valley, the backbone of California’s vast agricultural industry, are subsiding at the fastest rates ever measured, said Michelle Sneed, a U.S. Geological Survey hydrologist and lead author of the recent report.
Surveyors will ski into the Sierra Nevada mountains Tuesday to perform what has become an anxiously watched rite of spring in drought-stricken California: measuring snow to determine how much water will flow to the state this year.
A critical measure of a precious resource, April’s survey will influence whether the state’s water officials declare that the drought is easing or that it persists. At stake is the fate of summer water deliveries to farms and cities. (Related: “Could California’s Drought Last 200 Years?“)
Trailed by news media, surveyors will traverse a granite ridge on Lake Tahoe’s 6,800-foot-high (2,073-meter-high) Echo Summit—dense with fragrant pine, fir, and cedar—then drive about ten aluminum tubes into the snow to measure depth. They weigh the samples to gauge water content.
