The hydroclimate history of North America includes the formation and desiccation of large
inland lakes and the growth and ablation of glaciers throughout the Quaternary period. At the …

Bulk dissolution rates for sediment from ODP Site 984A in the North Atlantic are determined
using the 234 U/ 238 U activity ratios of pore water, bulk sediment, and leachates. Site 984A …

The use of hydraulic fracturing techniques to extract oil and gas from low permeability shale
reservoirs has increased significantly in recent years. During hydraulic fracturing, large …

Hydraulic fracturing of unconventional hydrocarbon reservoirs is critical to the United States
energy portfolio; however, hydrocarbon production from newly fractured wells generally …

Hydraulic fracturing of unconventional shale reservoirs increases the fracture network
surface area to access hydrocarbons from the low permeability rock matrix. Porosity and …

To evaluate the effectiveness of several mitigation strategies, we developed two-dimensional
flow and transport simulations of carbon dioxide (CO 2 ) leakage through the fractured …

In recent years, the availability of airborne imaging spectroscopy (hyperspectral) data has
expanded dramatically. The high spatial and spectral resolution of these data uniquely enable …

Context: Patients with panhypopituitarism have impaired quality of life (QoL) despite GH
replacement. They are profoundly androgen deficient, and dehydroepiandrosterone (DHEA) …

Injection of hydraulic fracturing fluid (HFF) into shale formations for unconventional oil/gas
production results in chemical reactions in the shale matrix. Our recent experimental study …

The late Cenozoic was a time of global cooling, increased aridity, and expansion of grasslands.
In the last two decades numerous records of oxygen isotopes have been collected to …
