Appendix A: Borehole Data (Thesis Appendix, 2013), David J. Richey Dec 2012

Appendix A: Borehole Data (Thesis Appendix, 2013), David J. Richey

David J Richey

Select borehole data compiled and organized from Utah Division Oil, Gas and Mining (www.oilgas.ogm.utah.gov). The data found here include API well numbers, names of all wells used, well datum as defined by the elevation above sea level measured at the Kelly Bushing on the drilling floor, and the depth to various formation tops encountered during drilling measured in drilling depth.

Approaching Cave Level Identification With Gis: A Case Study Of Carter Caves, Brianne Jacoby, Eric Wade Peterson, John C. Kostelnick, Toby J. Dogwiler

Eric Wade Peterson

Cave passages that are found at similar elevations are grouped together and called levels. The current understanding is that passages within a level are speleogenetically linked to a common static baselevel or stratigraphic control. Cave levels have provided an interpretive framework for deciphering cave development, landscape evolution, and climatic changes. Cosmogenic dating has been successfully used to interpret levels in Mammoth Cave and the Cumberland Plateau; however, this technique is expensive and there are limited funding resources available. Geographic information systems may be used as preliminary procedures to identify cave levels and constrain the timing of level development. A GIS …

Cmaf - Chris Morphological Adaptive Filter, Przemysław Kupidura

Przemysław Kupidura

The paper presents a new method of CHRIS images filtering. The presented algorithm is based on mathematical morphology operations and allows to correct the main CHRIS images noise types, like missing pixels and vertical stripes caused by a malfunctioning of the device. the algorithm is preceded by the brief discussion on the nature of the noise and the basis of mathematical morphology. The resulting images are compared to the results of application of other types of CHRIS-dedicated algorithms (Settle methods).


Bedrock Strength And River Metrics: Spatial And Statistical Correlations On The Incision Of The Colorado Plateau, Southwest Usa, Natalie Bursztyn, Joel Pederson Dec 2012

Bedrock Strength And River Metrics: Spatial And Statistical Correlations On The Incision Of The Colorado Plateau, Southwest Usa, Natalie Bursztyn, Joel Pederson

Natalie Bursztyn

There has been renewed debate over the mechanisms and timing of both uplift and erosion in the Colorado Plateau. Yet, in order to understand the patterns of topography and surficial processes in this landscape a third factor of bedrock properties must be considered. We are building a dataset of bedrock strength and exploring it in the context of topographic metrics. Included are rock-strength measures such as Schmidt-hammer compressive strength, Selby rock-mass strength, and laboratory tensile strength measures. To estimate the strength of units too incompetent to test directly, such as the shales prevalent in the region, we utilize functional relations …

Biomarker And Sedimentological Investigations Of Mis 8 Through Mis 12 From Lake El'gygytgyn, Ne Arctic Russia, Jeremy H. Wei, Julie Brigham-Grette, David Finkelstein, Isla S. Castañeda Dec 2012

Biomarker And Sedimentological Investigations Of Mis 8 Through Mis 12 From Lake El'gygytgyn, Ne Arctic Russia, Jeremy H. Wei, Julie Brigham-Grette, David Finkelstein, Isla S. Castañeda

Jeremy H Wei

Multiple proxy analysis of lake sediment records are crucial for understanding changes in environmental and climate conditions over historical and geological time. Most recently, the use of biomarker proxies coupled with sedimentological investigations provides a new approach for gaining insight into the lake processes that capture information about past climate change. This approach is applied here to better understand the paleoclimate record from Lake El’gygytgyn in Western Beringia. Multiple organic geochemical compound concentrations were measure as proxies for both aquatic and terrestrial biological productivity. Measurements of n-alkane (plant leaf waxes) as well as concentrations of the compounds arborinol (marker for …
