Using a geology-based assessment methodology, we estimated a total of 1.32 trillion barrels of oil in place in eighteen oil shale zones in this Eocene geologic unit.
We estimated mean undiscovered resources of 113.7 trillion cubic feet of natural gas, a mean of 690 million barrels of oil, and a mean of 3.7 billion barrels of natural gas liquids in onshore lands and state waters in this area.
We estimated mean volumes of 487 million barrels of oil, 9.8 trillion cubic feet of gas, and 408 million barrels of natural gas liquids in this area using a geology-based assessment methodology.
Explains the important paleoclimatic information we have obtained from this subaqueous cavern. The time-series data show important contrasts with what would be predicted from orbital theory, provoking extensive scientific discussion.
Revised geologic time scale indicating the ages of the lower bounds of chronostratigraphic and geochronologic units as they are currently known. Modifications to those ages made since the previous time scale was released (2007) are clearly marked.
Geophysical surveying, combined with analysis of sediment cores and radiometric dating were used to describe the likely history of formation of this area.
The National Assessment of Coastal Change Hazards is a multi-year undertaking to identify and quantify the vulnerability of U.S. shorelines to coastal change hazards such as the effects of severe storms, sea-level rise, and shoreline erosion and retreat.
The Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is conducting an analysis of historical shoreline changes along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii.
Booklet (PDF format) on the Pleistocene glaciations known as the Great Ice Age and the resulting geomorphological, climatic, and environmental changes that occurred on Earth during the period.
