Detection Of Subsidence In West-Central Florida Using Persistent Scatterer Interferometry And Near-Surface Geophysics, Tonian R. Robinson

USF Tampa Graduate Theses and Dissertations

This dissertation consists of three studies that employ Persistent Scatterer Interferometry (PSI, also known as PSInSAR) to better understand how subsidence in west-central Florida relates to underlying geological processes. In the first study, near-surface geophysical methods (Ground Penetrating Radar (GPR) and Electrical Resistivity (ERT)), terrestrial remote sensing applications (Light Detection and Ranging (LiDAR) and Structure from Motion (SfM)), and PSI were used to monitor the spatial and temporal behaviors of a suspected growing sinkhole in the Sandhill Boyscout Reservation, Hernando County, Florida. The survey area was located within and around a topographic low assumed to be the surface of the …

Geophysical, Archaeological, And Geospatial Investigations At Presidio Los Adaes, 18th Century Capital Of Spanish Texas, Robert Linam

Electronic Theses and Dissertations

Presidio Los Adaes (16NA16), located in present day northwest Louisiana, served as the capital of Spanish Texas for much of the 18th century. Maps and historical documents provide architectural plans for the fort and other buildings on the site but differ in the size and location of several buildings. In 2009, a geophysical survey of the site with ground penetrating radar, magnetometry, electrical resistance, and electromagnetic induction showed good preservation of architectural foundations. Visual assessment of the maps and geophysical data, information from archaeological excavations, and spatial statistics suggests that the fort was originally built as specified by the architect, …

A Survey Of And Site Treatment Plan For The Belle Creek Mounds Archeological Site, 21gd0072, In Goodhue County, Minnesota, Alexander T. Anton

All Graduate Theses, Dissertations, and Other Capstone Projects

The Prairie Island Indian Community (PIIC) recently purchased property, on which a portion of a prominent archeological site, encompassing 67 formerly documented burial mounds, resides. In order to better protect the burial mounds and other culturally significant material on the site, as well as on sites residing on the remainder of their new property, the PIIC enlisted the support of Minnesota State University, Mankato’s Earth Science, Archeology, Resources, and Terrestrial Hazards (EARTH) Systems Research Laboratory in developing a site treatment plan. Developing a useful site treatment plan necessitated conducting a geoarcheological survey of a portion of the archeological site, known …

Archaeological, Geophysical, And Geospatial Analysis At David Crockett Birthplace State Park, In Upper East Tennessee, Reagan Cornett

Electronic Theses and Dissertations

A geophysical survey was conducted at David Crockett Birthplace State Park (40GN205, 40GN12) using ground-penetrating radar (GPR) and magnetometry. The data indicated multiple levels of occupation that were investigated by Phase II and Phase III archaeological excavations. New cultural components were discovered, including the remnants of a Protohistoric Native American structure containing European glass trade beads and Middle Woodland artifacts that suggest trade with Hopewell groups from Ohio. A circular Archaic hearth was uncovered at one meter below surface and similar deep anomalies were seen in the GPR data at this level. A semi-automated object-based image analysis (OBIA) was implemented …

Landscape-Scale Geophysics At Tel Shimron, Jezreel Valley, Israel, Rachel Grap

Electronic Theses and Dissertations

Ground-penetrating radar (GPR) and magnetometry were used at Tel Shimron, an archaeological site in Israel’s Jezreel Valley. GPR primarily measures electric properties while magnetometry measures magnetic properties, making them complementary methods for subsurface prospection. Magnetometry can be collected and processed quickly, making it an ideal landscape-scale reconnaissance tool. It takes more time to collect, process, and interpret GPR data, but the result is a higher resolution dataset. In addition, GPR often works better than magnetometry in desert environments such as the Jezreel Valley. Conventional wisdom suggests that GPR should not be used as a landscape-scale reconnaissance tool unless there is …

Remote Sensing Insights Into Storage Capacities Among Plains Village Horticulturalists, Adam Wiewel

Graduate Theses and Dissertations

Maize was a fundamental component of the diet and economy of Middle Missouri Plains Village groups, sedentary farmers with settlements along the Missouri River during the last millennia. More than a century of study has contributed to our understanding of agricultural production among these peoples, but little effort has been made to consider temporal variation in production. Such an understanding is crucial to examining changes that occurred before and after the arrival of colonists and their trade goods in the seventeenth century. Plains archaeologists have suggested that the storage capacity of Middle Missouri villages increased during the sixteenth through the …

Geophysical And Remote Sensing Applications For A Better Understanding Of The Structural Controls On Groundwater Flow In The Lucerne Valley, California, Dale R. Dailey

Masters Theses

An integrated study was conducted in the Mojave Basin to investigate the potential role of faults and basement uplifts for groundwater flow in the Mojave Desert. Observations made include: 1) Very Low Frequency (VLF) measurements across mapped (using LIDAR and Geoeye-1 imagery) fault traces showed significant radio field dip angles indicative of presence of shallow sub-vertical, sheet-like conductors; many of the VLF tilt peaks coincided with changes in the magnetic profiles; 2) Vertical Electric Soundings indicate shallow basement west of, and parallel to, the Helendale Fault and deep saturated zones east of the fault/basement outcrop (F/B); and 3) isotopic analyses …

Constraints On The Structure Of The Border Ranges Fault System, South-Central Alaska From Integrated 3d Inversion Of Gravity/Magnetic Data, Niti Mankhemthong

Open Access Theses & Dissertations

I use updated gravity data, available aeromagnetic data, and other geophysical information as constraints to develop 2D and 3D structural models of density and magnetic susceptibility to better locate and determine the shape of the Border Ranges fault system (BRFS), the Border Range ultramafic and mafic assemblages and other forearc-arc boundary structures in south-central Alaska, that have previously been studied in only limited detail. There are three geophysical research projects that form the chapters of the dissertation. First, I estimated near-surface density variations in the central Kenai Peninsula based on the adaptation of the Nettleton (1939)-Parasnis (1952) method using Tarantola …

Improvements In Multi-Tool Surveying Efficiency For Archaeological Geophysics, Caitlyn Marie Williams

Masters Theses

Conventional archaeological excavation methods are, by nature, extremely invasive and result in study areas being irrevocably altered for the sake of research. For this reason, near-surface geophysical techniques have been incorporated into archaeological investigations to aid in determining the locations of buried features with minimal damage to the site. The objective of this research was to perform a geophysical survey at an archaeological site on the Akrotiri Peninsula in Cyprus to locate evidence of a Roman naval base and to develop an improved data management workflow that will improve the usefulness of geophysical data to archaeologists.

An on-site archaeologist determined …
