A Geophysical Survey Of Active Volcanism In The Central And Southern Andes
… and triggered earthquakes. I then conduct a survey using satellite thermal infrared data to detect thermal hotspots related to volcanic activity throughout the CVZ and SVZ. I find hotspots at many volcanoes that had not previously been documented, with the CVZ containing more volcanoes with …

An investigation as to the suitability and effectiveness of geophysical survey techniques as a tool to aid archaeological interpretation of upland sites within the area of south east Wales
Geophysical survey as a tool to aid archaeological interpretation has been shown to be of varied usefulness across the differing site morphology and underlying geology of Wales. Its uptake has also varied greatly between regions with bias often existing towards certain types of site or particular …

A reappraisal of archaeological geophysical surveys on Irish road corridors 2001-2010. With particular reference to the influence of geological, seasonal and archaeological variables
Geophysical surveys in the Republic of Ireland and elsewhere rarely have the opportunity to receive direct, meaningful and quantitative feedback from ground observed excavations, despite their frequent occurrence as a subsequent phase of development-led archaeological projects. This research …

An Evaluation of Geophysical Methods in the Detection of Toddler-Sized Burials During the First Six Months of Burials
Geophysical survey has become a major tool in the search for clandestine graves associated with missing person cases. However, relatively little research has been done to evaluate the efficacy of different instruments. Ground-penetrating Radar (GPR), magnetometry, resistivity, conductivity, and …

Time-lapse Geophysical Investigations over Known Archaeological Features Using Electrical Resistivity Imaging and Earth Resistance
Electrical methods of geophysical survey are known to produce results that are hard to predict at different times of the year, and under differing weather conditions. This is a problem which can lead to misinterpretation of archaeological features under investigation. The dynamic relationship …

WESSELMAN FARM, AN ARCHAIC SITE ON THE LOWER GREAT MIAMI RIVER, HAMILTON COUNTY, OHIO
… The landowner’s collection, archival research, geophysical survey, archaeological excavations, and radiocarbon dates each contributed valuable information in locating and interpreting this incredible archaeological site. The data also allows an understanding of the role this site had within the …

Investigating the role of groundwater - surface water connectivity in supporting non-perennial river systems, Sandveld, Western Cape, South Africa
… a water presence, groundwater level, and geophysical survey was conducted in order to develop a conceptual understanding of the multi-scale interaction occurring within the Verlorenvlei basin. Results of the isotopic and chemical analysis of water sources revealed the water origin and …

Late cenozoic shallow marine diamond placers off the northern Sperrgebiet, Namibia
… and diamond occurrence. Using detailed geophysical survey data (Sidescan Sonar and Multi-beam Bathymetry), the deposition of diamonds at these sites were modelled in GIS-based reconstructions. The diamond size frequency distribution (SFO) of the Shallow Marine (0 to -30 m) deposits in …

Investigation of Magnetic Soils on the Oak Ridge Reservation, TN
A 1993, airborne geophysical survey found numerous localized "bull's-eye" magnetic anomalies, apparently of natural origin, associated with dolines on the Oak Ridge Reservation (ORR), Oak Ridge, Tennessee. Susceptibility measurements made on a soil core extracted from one such doline located on …

Archaeological geophysical prospection in peatland environments.
… aimed to examine the potential for conventional geophysical survey methods (resistivity, gradiometry, ground penetrating radar and frequency domain electromagnetic) as site prospection and landscape investigation tools in peatland environments. It examines previous attempts to prospect peatland …

Medieval rural settlement: a study of Mid-Argyll, Scotland
… which involved a combination of archaeological survey and historic geography. The techniques used included archaeological fieldwork, excavation, geophysical survey, and the consultation of historic maps, documentary evidence and aerial photographs. The area covered in this thesis includes the …

Creating the Cahokian Community: the Power of Place in Early Mississippian Sociopolitical Dynamics
… Lohmann phase (A.D. 1050–1100). The mapping, geophysical survey, excavation, and material analyses for each of these sites combined with regional comparisons using a Geographic Information System provide evidence for changes in the construction of space, movement of people into and around the …

Antecedent Geologic Controls on the Distribution of Oyster Reefs in Copano Bay, Texas
… controls on the distribution of oyster reefs, a geophysical survey of Copano Bay was conducted in June and July 2007. Surficial sediment analysis confirms that the recent sedimentation in Copano Bay is comprised of mostly estuarine mud with little sand or shell, large extents of oyster reefs and …

Geophysical, geochemical and arable crop responses to archaeological sites in the Upper Clyde Valley, Scotland
… thesis considers the geochemical links between geophysical survey results from, and responses of barley crop growth to, the existence of plough-levelled archaeological sites. It takes as a starting point the results of magnetic and resistivity surveys undertaken at three sites in the Upper Clyde …
