Decline In Snowfall Has Negative Impacts On Plants, Animals
2013-05-07 19:29:15

Lee Rannals for redOrbit.com — Your Universe Online Plants and animals that thrive in deep snowfall seasons are having a tough time in recent years as less and less snow drops down its blanket. Scientists writing in the journal Frontiers in Ecology and the Environment say the gradual decay of the Northern Hemisphere's snowfall is having an impact on life that depends on it. The seasonal microenvironment that relies on snowfall, known as "subnivium," has an effect on everything...

NASA To Map Snowpack Of Two Major Mountain Watersheds In Colorado And California
2013-05-03 09:00:35

Alan McStravick for redOrbit.com - Your Universe Online In the very near future, the global issue surrounding the need for natural resources will shift from fossil fuels to fresh water. In preparation for this change of need, NASA has endeavored on a new airborne mission to create the first maps of the entire snowpack of two major mountain watersheds in California and Colorado. These western snow reserves, as they melt, provide greater than 75 percent of the total freshwater supply for the...

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...

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...

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
2014-01-12 00:00:00

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...
