USGS Releases New Assessment of Gas Resources in the Marcellus Shale, Appalachian Basin

The Marcellus Shale contains about 84 trillion cubic feet of undiscovered, technically recoverable natural gas and 3.4 billion barrels of undiscovered, technically recoverable natural gas liquids according to a new assessment by the U. S. Geological Survey (USGS).

These gas estimates are significantly more than the last USGS assessment of the Marcellus Shale in the Appalachian Basin in 2002, which estimated a mean of about 2 trillion cubic feet of gas (TCF) and 0.01 billion barrels of natural gas liquids. (more…)

Ecologist: Up-and-Coming Forests Will Remain Important Carbon Sinks

COLUMBUS, Ohio – The aging forests of the Upper Great Lakes could be considered the baby boomers of the region’s ecosystem.

The decline of trees in this area is a cause for concern among policymakers and ecologists who wonder whether the end of the forests’ most productive years means they will no longer offer the benefits they are known for: cleansed air, fertile soil, filtered water and, most important to climate change analysts, carbon storage that offsets greenhouse gas emissions.

PASADENA, Calif. –– Tiny crystals of a green mineral called olivine are falling down like rain on a burgeoning star, according to observations from NASA’s Spitzer Space Telescope.

This is the first time such crystals have been observed in the dusty clouds of gas that collapse around forming stars. Astronomers are still debating how the crystals got there, but the most likely culprits are jets of gas blasting away from the embryonic star. (more…)
