Study Finds Deep, Permeable Soils Buffer Impacts Of Agricultural Fertilization On Streams And Rivers In Southern Amazon
2013-04-24 14:36:32

Marine Biological Laboratory The often damaging impacts of intensive agriculture on nearby streams, rivers, and their wildlife has been well documented in temperate zones, such as North America and Europe. Yet a new study in an important tropical zone–the fast-changing southern Amazon, a region marked by widespread replacement of native forest by cattle ranches and more recently croplands–suggests that at least some of those damaging impacts may be buffered by the very deep...

First method to use weather station measurements to obtain daily evaporation rates Researchers at Columbia Engineering and Boston University have developed the first method to map evaporation globally using weather stations, which will help scientists evaluate water resource management, assess recent trends of evaporation throughout the globe, and validate surface hydrologic models in various conditions. The study was published in the April 1 online Early Edition of Proceedings of the...

Climate Change Not At Fault For Record US Drought In 2012
2013-04-12 15:09:41

Brett Smith for redOrbit.com - Your Universe Online In pushing for his green agenda, President Barack Obama has repeatedly cited last year´s massive drought, which cost the US $35 billion, as evidence of climate change. However, a new report from the National Oceanic and Atmospheric Administration (NOAA) found that a bizarre confluence of natural variations was responsible for the precipitous drop in rainfall levels across the United States last summer. "This is one of those...

If you've ever stood on a hill during a rainstorm, you've probably witnessed landscape evolution, at least on a small scale: rivulets of water streaming down a slope, cutting deeper trenches in the earth when the rain turns heavier. It's a simple phenomenon that scientists have long believed applies to large-scale landforms as well – that is, rivers cut faster into mountains that receive heavier precipitation. It's thought that if rainfall patterns influence how rivers cut into rock,...

Australian scientists have devised a way to model polluted groundwater with computer simulation — and better protect the Earth´s main fresh water supply. Researchers at the National Centre for Groundwater Research and Training (NCGRT) have developed a new model to predict where — and how fast — polluted groundwater can move from a contaminated site, allowing water managers to better locate and clean up the water. This could help defeat an emerging threat beneath...

New Chart Shows Entire Topography Of Antarctic Seafloor In Detail
2013-04-09 15:10:20

Alfred Wegener Institute for Polar and Marine Research Reliable information on the depth and floor structure of the Southern Ocean has so far been available for only few coastal regions of the Antarctic. An international team of scientists under the leadership of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, has for the first time succeeded in creating a digital map of the entire Antarctic seafloor. The International Bathymetric Chart of the Southern Ocean...

Salt Levels In Draa Basin Groundwater A Detriment To Farming
2013-04-08 19:37:12

Brett Smith for redOrbit.com — Your Universe Online Arid but habitable regions around the world depend on limited water resources for drinking and crop irrigation. Any disruption or contamination of the water supply could be a major problem for a local population. The Draa Basin in Sub-Saharan Africa is one such region, as it has relied on runoff from Morocco's High Atlas Mountains. It has also been dammed and directed toward oases hundreds of miles to the south. A group of...

Endorheic Basin
2013-04-18 22:40:14

An endorheic basin, from the Ancient Greek endon, meaning “within” and rhein, meaning “to flow”, is a closed drainage basin that holds onto water and does not allow outflow to other external bodies of water, such as oceans or rivers, but joins instead into lakes or swamps, seasonal or permanent, that equilibrate via evaporation. Basins such as these might also be referred to as closed or terminal basin or as internal drainage systems. Usually, water that has built up in a drainage...

Precipitation Record For Spokane WA Area First Six Months Of 2012
2012-07-01 11:32:28

January 2012: Started out dry as the area only received 1.06in of rainfall which is about .76in below normal leading to an annual deficit of .76in. February 2012: Followed in January’s footsteps as being dry again; the area got only .99in of rainfall which lead to the annual deficit becoming 1.01in. March 2012: The area received a nice welcoming 3.29in of rainfall on the month which is about 1.92in above normal and brought the annual amount back to a positive 1.08in. April 2012:...

A drainage divide, water divide, divide, or watershed is the line that separates neighboring drainage basins. In flat country the divide may be invisible (just a notional line on the ground either side of which water starts its journey to different waterways). While, in hilly country, the divide lies along peaks and ridges. Drainage divides are important geographical, and sometimes political boundaries. Roads and railways often follow divides to minimize slopes and marshes and rivers....

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...

Environmental Science

Environmental science is a science that contains a wide range of scientific disciplines. These disciplines are grouped together based on the natural environment which they encompass and interact with. These sciences include physical, chemical, and biological components. Environmental science provides an interdisciplinary approach to the study of the environmental systems. The most common way environmental science is studied is through the work of one individual or small team drawing on the...
