[1] The surface pattern of vegetation influences the composition and humification of peat laid down during the development of a bog, producing a subsurface hydrological structure that is expected to affect both the rate and pattern of water flow. Subsurface peat structures are routinely derived from the inspection of peat cores. However, logistical limits(More)
We have used geostatistical analysis of radar reflections to quantify the correlation structures found in 2-D ground-penetrating radar (GPR) images. We find that the experimental semivariogram, the product of the geostatistical analysis of the GPR data, is well-defined and can be modeled using standard geostatistical models to obtain an estimate of the(More)
Image texture is one of the key features used for the interpretation of radar facies in ground-penetrating radar GPR data. Establishing quantitative measures of texture is therefore a critical step in the effective development of advanced techniques for the interpretation of GPR images. This study presents the first effort to evaluate whether different(More)
The establishment of the settlement at the start of the 2nd millennium BCE in the Nami region of Israel marks the beginning of a new era of human habitation in this region, following a hiatus of ca 500 years. Tel Nami was deserted ca. 200 years later, not to be settled again for another 400 years or more. Nami is in a system that combines wetlands and(More)
Subsurface stratigraphy provides insight into the genesis and evolution of coastal landscapes. Since ground penetrating radar (GPR) provides an ideal way to image subsurface stratigraphy it is commonly used to help understand how coastal landscapes evolve. The Lake Superior shoreline provides an excellent opportunity to study coastal environments. Grand(More)
Sand Point is a small cuspate foreland located along the southeastern shore of Lake Superior within Pictured Rocks National Lakeshore near Munising, Michigan. Park managers’ concerns for the integrity of historic buildings at the northern periphery of the point during the rising lake levels in the mid-1980s greatly elevated the priority of research into the(More)
