Testing Mechanisms Of Subduction Zone Segmentation And Seismogenesis With Slip Distributions From Recent Andean Earthquakes, John P. Loveless, M. E. Pritchard, K. Kukowski 2010 Smith College

Testing Mechanisms Of Subduction Zone Segmentation And Seismogenesis With Slip Distributions From Recent Andean Earthquakes, John P. Loveless, M. E. Pritchard, K. Kukowski

Geosciences: Faculty Publications

A long-standing goal of subduction zone earthquake studies is to determine whether or not there are physical processes that control seismogenesis and the along-strike segmentation of the megathrust. Studies of individual earthquakes and global compilations of earthquakes find favorable comparison between coseismic interplate slip distributions and several different long-lived forearc characteristics, such as bathymetry, coastline morphology, crustal structure, and interplate frictional properties, but no single explanation seems to govern the location and slip distribution of all earthquakes. One possible reason for the lack of a unifying explanation is that the inferred earthquake parameters, most importantly the slip distribution, calculated in ...


Modern Variation In Predation Intensity: Constraints On Assessing Predator-Prey Relationships In Paleoecologic Reconstructions, James Funderburk 2010 University of South Florida

Modern Variation In Predation Intensity: Constraints On Assessing Predator-Prey Relationships In Paleoecologic Reconstructions, James Funderburk

Graduate Theses and Dissertations

The complex interaction between predators and their prey is rarely preserved in the fossil record. However, predation of marine mollusks by drilling gastropods leaves a diagnostic hole in the shell of the prey, possibly allowing for quantitative analysis of this ecological interaction. Drilling frequency, as measured in marine mollusks both in the Modern and fossil record, has been heralded as a potential opportunity to quantify these ecological interactions and use these values in the testing of hypotheses.

This study employed the collection, tallying, and analysis of bulk samples derived from shelly deposits on 45 Modern beaches along the contiguous coast ...


Exhumation Mechanisms Of The Greater Himalayan Sequence, Garhwal Region, India, Christopher James Spencer 2010 Brigham Young University - Provo

Exhumation Mechanisms Of The Greater Himalayan Sequence, Garhwal Region, India, Christopher James Spencer

All Theses and Dissertations

Geothermobarometric, micro- and macro-structural data indicate that peak metamorphic pressure and temperature of the Greater Himalayan Sequence (GHS) of the Garhwal Region of India increase dramatically across the Main Central Thrust (MCT). Metamorphic pressure and temperature increase from ~5 kbar and ~550 ºC in the Lesser Himalayan Crystalline Sequence (LHCS) in the footwall to ~14 kbar and ~850 ºC at ~3 km above the MCT in the hanging wall (GHS). Pressures decrease slightly upsection to ~8 kbar and temperatures remain nearly constant at ~850 ºC to the structurally overlying South Tibetan Detachment (STD). The LHCS exhibits a high temperature-depth gradient ...

Spatial Similarities And Differences Of Attributes Of Three Subwatersheds Within The Middle Smoky Hill River Watershed And Their Relationship To Instream Total Suspended Solids, Dustin Fross 2010 Fort Hays State University

Spatial Similarities And Differences Of Attributes Of Three Subwatersheds Within The Middle Smoky Hill River Watershed And Their Relationship To Instream Total Suspended Solids, Dustin Fross

Masters Theses

The objective of this study was to spatially analyze the attributes of three subwatersheds, Hydrological Unit Code 12 (HUC 12), of the Middle Smoky Hill River Watershed in west-central Kansas and relate the variances of the attributes to the concentrations of total suspended solids (TSS) entering the Smoky Hill River during storm events. This was accomplished by comparing land cover, including cropland, grassland, and urban factors; agricultural practices, such as tillage methods, condition of terraces, and the presence of grass waterways; geomorphology, including soil types, topography, and visible erosion; and lastly, precipitation variance. The three HUC 12s that were studied ...


A New Carnosaur (Dinosauria: Theropoda) From The Upper Morrison Formation (Late Jurassic, Tithonian) Of Colorado, Sebastian Dalman 2010 Fort Hays State University

A New Carnosaur (Dinosauria: Theropoda) From The Upper Morrison Formation (Late Jurassic, Tithonian) Of Colorado, Sebastian Dalman

Masters Theses

A disarticulated skeleton of a theropod from the Late Jurassic (Tithonian) strata of McElmo Canyon in Montezuma County, Colorado was discovered in 1953 by the late J. T. Gregory and D. Techter. For nearly 55 years the specimen remained unnoticed in the collection of the Yale Peabody Museum of Natural History in New Haven, Connecticut. Several cranial and postcranial elements are relatively well preserved and include the premaxilla, maxilla, dentary, teeth, quadratojugal, braincase, metacarpals, partial pubis and ischium, astragalus, partial tibia and fibula, metatarsals, pedal phalanges, and several partially preserved ribs. The specimen represents a new genus and species of ...

A Trekker’S Guide To The Khumbu Himalaya: Trailside Geology Along The Everest Base Camp Trek, Brigit Anderson

Independent Study Project (ISP) Collection

The Himalaya is the youngest and highest mountain range in the world. It thus provides a wonderful field lab for studying the mountain building process in action. The trek in the Khumbu (northeastern Nepal) from Lukla to Everest Base Camp takes you through the Higher Himalaya and some interesting geological features. This project gives an introduction to the larger Himalaya geology and more specifically geology of the Khumbu Region. It then follows the Lukla-Everest Base Camp (EBC) trekking route pointing out interesting geologic features along the way. Some of the concepts explained in this project are somewhat technical. For this ...

Neighborhood-Based Verification Of Precipitation Forecasts From Convection-Allowing Ncar Wrf Model Simulations And The Operational Nam, Adam J. Clark, William A. Gallus Jr., Morris L. Weisman

Geological and Atmospheric Sciences Publications

Since 2003 the National Center for Atmospheric Research (NCAR) has been running various experimental convection-allowing configurations of the Weather Research and Forecasting Model (WRF) for domains covering a large portion of the central United States during the warm season (April–July). In this study, the skill of 3-hourly accumulated precipitation forecasts from a large sample of these convection-allowing simulations conducted during 2004–05 and 2007–08 is compared to that from operational North American Mesoscale (NAM) model forecasts using a neighborhood-based equitable threat score (ETS). Separate analyses were conducted for simulations run before and after the implementation in 2007 of ...

Geospatial Data Portals: Librarians Add Expertise In The Development Of Gis Metadata Catalogs, Adonna Fleming 2010 University of Nebraska-Lincoln

Geospatial Data Portals: Librarians Add Expertise In The Development Of Gis Metadata Catalogs, Adonna Fleming

Faculty Publications, UNL Libraries

Searching a geospatial data catalog can be frustrating for many GIS data users. Geospatial data catalogs are built on records created to a specific metadata standard, such as ISO 19115. The search query is often limited to searching a few tags within the record, such as title, publisher, spatial extent, content theme, and content type. GIS personnel tend to create metadata records with little thought into how it will be discovered by others. On the other hand, library catalogs are developed for a broad spectrum of users with varying knowledge of the subject. Librarians can bring this expertise in creating ...


Experimental Estimation Of The Gpr Groundwave Sampling Depth, Katherine R. Grote, Taylor Crist, Crystal Nickel 2010 Missouri University of Science and Technology

Experimental Estimation Of The Gpr Groundwave Sampling Depth, Katherine R. Grote, Taylor Crist, Crystal Nickel

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Monitoring near-surface soil water content is essential for efficient water management and for understanding hydrologic processes in soils. Ground-penetrating radar (GPR) groundwaves are an approach that can be used to monitor the near-surface soil water content, but the efficacy of this technique is currently limited by the uncertainty surrounding the groundwave sampling depth. This research experimentally determines the sampling depth of GPR groundwaves under dry and saturated conditions in a sandy soil. Data were acquired using 250, 500, and 1000 MHz antennas within an experimental tank containing soil layers of contrasting electromagnetic velocities. Results show that the groundwave sampling depth ...


Analysis Of The Gouldsboro Pluton And The Fehr Granite: Understanding The Scales Of Magmatic Processes And Partial Melt Generation From The Deep To Shallow Crust, George Christopher Koteas 2010 University of Massachusetts - Amherst

Analysis Of The Gouldsboro Pluton And The Fehr Granite: Understanding The Scales Of Magmatic Processes And Partial Melt Generation From The Deep To Shallow Crust, George Christopher Koteas

Open Access Dissertations

The heterogeneity of the continental crust has a first order control on the dynamics of plate tectonic processes and the compositions of the Earth in both time and space. Heterogeneity can be characterized at a variety of scales and in a multitude of tectonic environments, but it is the links between seemingly disparate tectonic settings and crustal levels that are critical in understanding construction of the continents. The focus of this dissertation work is to apply microtextural, microgeochemical, whole rock geochemical and traditional petrographic techniques to study features in both deep and shallow crustal igneous rocks. The goal of these ...
