Stream Temperatures Don’t Parallel Warming Climate Trend
2012-05-03 03:33:31

A new analysis of streams in the western United States with long-term monitoring programs has found that despite a general increase in air temperatures over the past several decades, streams are not necessarily warming at the same rate. Several factors may influence the discrepancy, researchers say, including snowmelt, interaction with groundwater, flow and discharge rates, solar radiation, wind and humidity. But even after factoring out those elements, the scientists were surprised by the...

There is potential to store large volumes of Australia´s precious fresh water underground, to offset climate change, avoid evaporation losses and meet national water needs into the future, leading water scientists say. Following a major national scientific workshop in Canberra last week, researchers in the National Centre for Groundwater Research and Training (NCGRT) say that managed aquifer recharge — the injection or infiltration of excess surface water into underground...

There was no change in concentrations of chloride, dissolved solids, or nitrate in groundwater for more than 50 percent of well networks sampled in a new analysis by the USGS that compared samples from 1988-2000 to samples from 2001-2010. For those networks that did have a change, seven times more networks saw increases as opposed to decreases. The analysis was done by the USGS National Water Quality Assessment Program (NAWQA) to determine if concentrations of these constituents have...

Increased intake of dietary calcium may be key to addressing widespread dental health problems faced by millions of rural residents in Ethiopia's remote, poverty-stricken Main Rift Valley, according to a new Duke University-led study. As many as 8 million people living in the valley are estimated to be at risk of dental and skeletal fluorosis as a result of their long-term exposure to high levels of naturally occurring fluoride in the region's groundwater. Fluoride is essential for...

Minimum Distance Urged To Protect Sensitive Rock Strata From Fracking

Brett Smith for RedOrbit.com Artificial fissures in the earth´s crust caused by hydraulic fracturing, or fracking, typically extend less than 600 meters, according to a new Durham University study. These findings could be very important for government officials looking to regulate the fracking industry, which has come under scrutiny for allegedly contaminating drinking water and causing seismic events. "Shale gas exploration is increasing across the world and sediments of...

100 Times More Groundwater In Africa Than Surface Water
2012-04-21 05:01:01

Researchers say they have created the most detailed map yet of groundwater across the entire continent of Africa. A group from the U.K. said they believe there is about 100 times the volume of water underground than there is on the surface of Africa. The team wrote in the journal Environmental Research Letters that they hope their map can improve access to water in Africa, where 300 million people are said to not have access to safe drinking water. Helen Bonsor, one of the authors of...

Water Pollution
2013-03-25 12:43:15

Water pollution is the contamination of bodies of water including rivers, oceans, lakes, aquifers and groundwater. Water pollution is when pollutants are discharged directly or indirectly into a body of water without adequate treatment to remove harmful compounds. Water pollution affects the plants and organisms that reside in these bodies of water. In almost all of the cases the effect is damaging not only to individual species and populations, but to the natural biological communities as...

The water cycle (or hydrologic cycle) describes the continuous movement of water above, below, and on the planet. Since the water cycle is in fact a "cycle", there is no beginning or end. Water exists in three states: liquid, vapor, and ice. Although the balance of water on our planet is fairly constant, individual water molecules may come and go. The water cycle is driven by the sun. The sun heats the oceans and allows water to evaporate into the air. The sun also heats snow and ice which...

toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
