Thawing permafrost will have far-reaching ramifications for populated areas, infrastructure and ecosystems. A geographer from the University of Zurich reveals where it is important to confront the issue based on new permafrost maps -- the most precise global maps around. They depict the global distribution of permafrost in high-resolution images and are available on Google Earth. Unstable cable-car and electricity pylons and rock fall — Alpine countries like Switzerland have already...

Most research initiatives aim to discover more knowledge. The International Polar Year (IPY) went even further; it created more discoverers. That is what Canadian Arctic researcher David Hik will tell this week's meeting of the American Association for the Advancement of Science (AAAS) in Vancouver. "For the first time in the 130-year history of international polar years, people living in polar regions were not just objects of study – they led studies," said Hik. "This was the...

Geologists carrying rock hammers and accompanied by Marines traverse the rugged expanse of the Helmand Province in southern Afghanistan, searching for untold mineral wealth. Although the nature of Afghanistan's mineral deposits is not unique in the world, the country's deposits are largely untouched. Will Afghanistan be able to utilize these minerals to rebuild the war-torn nation? Join EARTH Magazine in our January issue as we examine Afghanistan's mineral wealth and the implications it...

Image 1 - SMOS Maps Europe’s Dry Autumn Soils
2011-12-08 04:21:57

Dry soil resulting from Europe´s exceptionally warm and dry autumn is being monitored by ESA´s SMOS water mission. The images here show the stark comparison between soil moisture in November 2010 and November 2011. Like the most of the year, this autumn has been particularly dry. In the Netherlands, for example, just 9 mm of rain fell in November, compared to the average of 82 mm. According to the Royal Netherlands Meteorological Institute KNMI, November was the driest since...

What do geology and textiles have in common? More than you might think. Since the 1980s, coastal, ocean and hydraulic engineers have been reinforcing coastlines and cleaning up contaminated water from dredge materials and other sludges and slurries with a revolutionary fabric that combines the strength of certain textiles with geoscientific know-how. So far, geotubes have been an integral tool in protecting our delicate coastlines; however, the relative infancy of the innovation leaves many...

The American Geological Institute's Workforce Program today released an analysis of salaries for geoscientists by industry relative to those of other scientific fields. Geoscience Currents 51 shows that in 2010, average aggregated salaries for geoscience-related occupations ranged from $137,660 for geoscience-related occupations in the finance and insurance industry to $69,949 for geoscience-related occupations in state government. Salary ranges for the aggregated occupations were as narrow...

Image 1- Arctic Ice Closes In On Record Low
2011-09-14 07:15:20

  A new record low could soon be set for ice in the Arctic. The past five years have seen the lowest extent of sea ice since satellite measurements began in the 1970s. Earth observing satellites make it possible to measure the amount of sea ice in inaccessible areas such as the Arctic. This year, the extent of Arctic sea ice is comparable to the record low set in 2007. According to scientists at the University of Bremen in Germany, sea ice extent in early September has...

Arctic Sea Ice Extent Hits Record Low
2011-09-11 04:01:00

  The area covered by Arctic sea ice during the summer reached a new all-time low on Thursday, with the summer sea ice extent falling to 1.64 million square miles (4.24 million square kilometers), scientists from a German university reported on Friday. According to AFP reports on Saturday, the current level is approximately one-half a percent below the previous record low, which dates back to the first satellite observations in 1972. Researchers at the University of Bremen's...

WASHINGTON, Aug. 18, 2011 /PRNewswire-USNewswire/ -- NASA-funded researchers have created the first complete map of the speed and direction of ice flow in Antarctica. The map, which shows glaciers flowing thousands of miles from the continent's deep interior to its coast, will be critical for tracking future sea-level increases from climate change. The team created the map using integrated radar observations from a consortium of international satellites. (Logo:...

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...

Earth science (or geoscience) is the science of the planet Earth. Earth science can be broken down into four major disciplines, which are: geography, geology, geophysics, and geodesy. These disciplines use physics, chemistry, biology, chronology and mathematics to arrive to a greater understanding of the principal areas of the Earth system. Since Earth is the only known life-bearing planet, Earth science is solely dedicated to the geophysical makeup of our own planet. One discipline,...
