Earth Sciences

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.

Engineers work on their SUNTANS as they track waves and beaches

Nearly a month has passed since the wounded tanker Prestige spilled thousands of tons of heavy oil into the Atlantic and fouled dozens of Spanish beaches. But anxious residents of coastal Spain and Portugal remain on high alert – wondering where and when the noxious crude will wash ashore next.

In recent years, tanker accidents have ruined fisheries and tourist beaches from Alaska to France. But do oil spills always have to end in catastrophe? Perhaps the most vulnerable beaches and coastal

North Atlantic Oscillation part of the global picture

An especially cold winter in Europe, lots of snow in Scandinavia or lots of rain in the Mediterranean are all symptoms of what meteorologists call the North Atlantic Oscillation, but a group of Penn State researchers has gone beyond the symptoms to try to decipher the dynamics of this atmospheric pattern.

“Some scientists argue that the impact of the NAO on global climate is comparable to El Nino,” says Dr. Sukyoung Lee, associate professor of meteorology. “However, most of the scientific co

INEEL geoscientist to present NAPL contaminant modeling advance at AGU Meeting

DOE News Release Embargoed for release December 6, 2002 INEEL geoscientist to present NAPL contaminant modeling advance at AGU Meeting By modifying the mathematical theory describing the relationship between permeability, saturation, and pressure in a multiple fluid system, researchers can now more accurately predict the movement of non-aqueous phase liquid (NAPL) contaminants in the subsurface. New calculations account for residual NAPL that remains in the vadose zone-forming a long-term source f

Climate change will affect carbon sequestration in oceans, scientists say

The direct injection of unwanted carbon dioxide deep into the ocean is one suggested strategy to help control rising atmospheric carbon dioxide levels and mitigate the effects of global warming. But, like the problems associated with the long-term storage of nuclear waste, finding a safe place to sequester the carbon may be more difficult than scientists first anticipated.

Because the atmosphere interacts with the oceans, the net uptake of carbon dioxide and the oceans’ sequestration capac

Geophysicist develops method for finding underground contaminants

When a property is suspected of having contaminated soil or groundwater, it is usually a lengthy and costly process to confirm the presence of pollutants and to delineate the extent of the contamination. Soon that process may be simplified considerably.

University of Rhode Island geophysicist Reinhard Frohlich, an associate professor of geosciences, has devised a cost-effective, new method for finding underground contaminants that will reduce drilling and digging beneath the surface. By inse

Mapping with math

In an unexpected meeting of the minds, two Dartmouth professors from disparate fields have come together to solve a problem: how to make accurate models of remote landscapes from photographs.

Arjun Heimsath, Assistant Professor of Earth Sciences, and Hany Farid, Assistant Professor of Computer Science, have found a way to create three-dimensional models of remote regions using only two-dimensional digital photographs. Once built, these models make it easier for researchers to predict landsl
