Earth Sciences (also referred to as Geosciences), which deals with basic issues surrounding our planet, plays a vital role in the area of energy and raw materials supply.
Earth Sciences comprises subjects such as geology, geography, geological informatics, paleontology, mineralogy, petrography, crystallography, geophysics, geodesy, glaciology, cartography, photogrammetry, meteorology and seismology, early-warning systems, earthquake research and polar research.
Across the world, rivers wash mountains into the sea. In the beautiful and rugged mountains of southeast Alaska, glaciers grind mountains down as fast as the earths colliding tectonic plates shove them up.
“Like an ice palace cheese grater, glaciers sweep and grind rocks off of mountains. No matter how fast the plate pushes the rock up, the glacier will erode it just as fast,” said James A. Spotila of Blacksburg, assistant professor of geosciences at Virginia Tech. The National Science
Ohio State University engineers are helping satellites form a clearer picture of water quality in the Great Lakes.
The study — the first ever to rate the effectiveness of various computer models for monitoring the Great Lakes — might also aid studies of global climate change.
As algae flourishes in the five freshwater lakes every summer, satellite images show the water changing color from blue to green, explained Carolyn Merry, professor of civil and environmental engineeri
Hollywoods latest disaster movie, The Day After Tomorrow, is about to be released. It is a fictional account of the havoc wreaked by out-of-control climate as North America is beset by the chilling beginnings of a new Ice Age in the course of 10 days. The movie features numerous catastrophic weather events including hurricanes, tornadoes, floods, and tidal waves striking New York.
“Its a good yarn,” said Dr Tony Haymet, Chief of CSIRO Marine Research. “Like many of the catastroph
University of Southampton archaeologists Professor David Peacock and Dr Lucy Blue have just returned from a pioneering expedition investigating Roman sites in the East African country of Eritrea alongside colleagues from the University of Asmara. The University group is the first from the UK to work in the country since it won its independence more than a decade ago. They are already planning to return to this remote area on the shores of the Red Sea, previously part of Ethiopia.

Scientists working in the stormy and inhospitable waters off the Antarctic Peninsula have found what they believe is an active and previously unknown volcano on the sea bottom. The international science team from the United States and Canada mapped and sampled the ocean floor and collected video and data that indicate a major volcano exists on the Antarctic ontinental shelf, they announced on May 5 in a dispatch from the research vessel Laurence M. Gould, which is operated by the National Sc
Earths climate system is more sensitive to perturbations now than it was in the distant past, according to a study published this week in the journal Nature. The findings suggest a previously unrecognized role for tropical and subtropical regions in controlling the sensitivity of the climate to change. Christina Ravelo, an ocean scientist at the University of California, Santa Cruz (UCSC) , and her coauthors at UCSC and Boise State University, Idaho, focused on the Pliocene epoch, from
