Morphology Of The Lower Missouri River: The Processes Involving Development Of Highly Sinuous Gooseneck Loop Cutoffs Exposed In The Surficial Deposits Of The River Floodplain
(Geology, 2012-04-11)
Mapping the surficial deposits of the Missouri River from Sioux City, Iowa to Mondamin, Iowa brought to light a prominent set of landforms exposed in the floodplain and which are also easily visible via aerial photography. ...
Identifying Possible Hydrologic Recharge Zones In The Sangre de Cristo Aquifer on The Milliken Ranch in Las Vegas, NM
(Geology, 2012-04-11)
Groundwater at the periphery of mountain ranges in the desert southwest has its provenance in two possible sources: local or regional flow. This study sought to identify the source of deep groundwater from wells on ranches ...
Surface Lineaments And Lithofacies Distribution Of The Tyler Formation In Southwestern North Dakota
(Geology, 2012-07-25)
The purpose of this study is to investigate whether a correlation exists between surface lineaments and lithofacies distribution of the Pennsylvanian Tyler Formation in the southwest portion of North Dakota of the Williston ...
Correlation Of Sequence Stratigraphic Surfaces Of The Mid-cretaceous Dakota Group From Subsurface To Outcrop Southern Denver Basin, Colorado.
(Geology, 2011-10-11)
The D and J sandstone of the Cretaceous Dakota Group are considered as the major oil and gas producing units within in the Denver Basin. The distribution of these units in the Denver Basin is a sub-basin of the Early ...
An updated GPS velocity field for Puerto Rico and the Virgin Islands: Constraints on tectonic setting and internal-deformation
(2014-09-17)
Puerto Rico and the northern Virgin Islands define the eastern end of the Greater Antilles, while the Puerto Rico trench and the Muertos Trough define the northern and the southern limits of the North American - Caribbean ...
Predicting The Geographic Distribution Of Ancient Soils With Special Reference To The Cretaceous
(Environmental & Earth Science, 2012-04-11)
Different kinds of soils form in different climatic regimes. Soils closely match climatic conditions. Therefore, they are one of the best indicators of past climates. This study uses the "climate envelope" technique developed ...
Air Emissions From Natural Gas Exploration And Mining In The Barnett Shale Geologic Reservoir
(Environmental & Earth Science, 2011-10-11)
This study evaluates air emissions from natural gas mining and production in the Barnett Shale within the Dallas/Fort Worth Metroplex. Due to advances in horizontal drilling and hydraulic fracturing, natural gas production ...
Removal Of Butylene And Propylene Gas Using Biofiltration
(Environmental & Earth Science, 2010-03-03)
Air pollutants are produced from a variety of anthropogenic activities such as food production, wastewater treatment plants, painting, industrial activities, and biomass combustion. Such pollutants are becoming a cause ...
Proximity Of Cancer Cases To Airports Within The State Of Texas
(Environmental & Earth Science, 2012-07-25)
Determining whether the incidence of cancer may be associated with pollutants emitted from airports is important in order to better plan cities to reduce such incidences. This research aims to answer the following questions: ...
On The Sensitivity Of Ocean Circulation To Arctic Freshwater Pulses During The Paleocene/Eocene Thermal Maximum
(Environmental & Earth Science, 2010-03-03)
The Paleocene/Eocene Thermal Maximum (PETM) corresponds to a period characterized by extreme global warming caused by a massive carbon input into the ocean and atmosphere. Approximately 55 Ma in the early Cenozoic, evidence ...
