Abstract
Geophysical investigation of the site of the former monastic settlement, Clonard, County Meath, Ireland
Paul J Gibson
Dorothy M George
45 - 56
Clonard, in County Meath, was a major ecclesiastical centre from the early-sixth century to the twelfth century and buildings associated with the monastery were in existence until the late-eighteenth century. However, today no extant buildings or features associated with the monastery are known. The geophysical investigation undertaken in this project has uncovered many anomalies which may be related to the monastic settlement at Clonard. A significant number of linear anomalies have been detected east of St Finian's church using magnetic gradiometry and twin electrode resistance surveying. Many of these anomalies are probably field boundaries; however, a much greater diversity of geophysical responses is located south and west of St Finian's church. A subsquare enclosure of 60m sides is adjacent to a 300m long palaeochannel. A fine network of intersecting low resistance anomalies probably represent former artificial drainage channels. Three large areas associated with anomalous magnetic readings were located which might indicate sites of human activity. In addition, there are four distinct zones which have large concentrations of high resistance values suggesting the presence of walls or buildings. Resistivity and ground-penetrating radar depth slices show that one of these zones has characteristics which indicate the presence of an east--west aligned building approximately 7m wide in a north--south direction and about 15m long in an east--west direction.
Integrating multidimensional geophysical data
Kenneth L Kvamme
57 - 72
The author contends that surveys that utilize multiple geophysical methods offer greater insights about the subsurface because each one generally yields different information. Common approaches to integrating or fusing multidimensional geophysical data are investigated utilizing computer graphics, geographical information system (GIS), mathematical and statistical solutions. These approaches are synthesized into graphical, discrete and continuous domains. It is shown that graphical approaches allow complex visualizations of the subsurface, but only images are generated and their dimensionality tends to be low. Discrete methods incorporate any number of geophysical dimensions, allow application of powerful Boolean operations, and produce unambiguous maps of anomaly presence or absence, but many of these methods rely on arbitrary thresholds that define only robust anomalies. Continuous data integrations offer capabilities beyond other methods because robust and subtle anomalies are simultaneously expressed, new quantitative information is generated, and interpretive data are derived in the form of regression weights, factor loadings, and the like, that reveal interrelationships and underlying dimensionality. All approaches are applied to a common data set obtained at Army City, Kansas, USA, a World War I era commercial complex. Utilizing data from six geophysical surveys (magnetic gradiometry, electrical resistivity, ground-penetrating radar, magnetic susceptibility, soil conductivity, aerial thermography), various data integrations reveal the structure of this nearly forgotten town.
