Abstract Understanding the local stratigraphy and geometry of sediment units is necessary for successful 3D modelling prediction ground behaviour engineering-geological properties urban land use construction. A detailed model main Rastaala basin in southern coastal Finland was constructed, combining a conceptual geological information from drill-hole logs geotechnical drilling. The based on cro...

According to EuroGeoSurveys, the European Geological Surveys association, “Geological spatial data and models describe the solid Earth’s surface and subsurface on-shore and off-shore, its nature, structure, properties, dynamics and evolution over time; including its related (geo)resources and (geo) hazards”. This illustrates a modern vision of the core mission that National Geological Surveys h...

The ability to delineate geologic facies and to estimate their properties from sparse data is essential for modeling physical and biochemical processes occurring in the subsurface. If such data are poorly differentiated, this challenging task is complicated further by the absence of a clear distinction between different hydrofacies at locations where data are available. We consider three altern...

The professionalization of Canadian anthropology in the first half of the twentieth century was tied closely to the matrix of the federal state, first though the Anthropology Division of the Geological Survey of Canada and then the National Museum. State anthropologists occupied an ambiguous professional status as both civil servants and anthropologists committed to the methodological and disci...

Vegetation modelling is an important topic in the sciences in at least two streams of applications. The former applies the modelling and simulation of vegetation for predicting the impacts of climate change on forestry, studies of forest succession for resource and habitat management, and animal habitat modelling while the latter attempts to reconstruct past landscapes for geological studies or...

The Voronoi diagram (VD) and the Delaunay triangulation (DT) can be used for modelling different kinds of data for different purposes. These two structures are attractive alternatives to rasters to discretise a continuous phenomenon such as the percentage of gold in the soil, the temperature of the water, or the elevation of a terrain. They can also be used to represent the boundaries of real-w...

This paper illustrates the malleable boundaries that define nature. Personal construct theory is employed to examine the apparent contradiction of the human/nature binary posed by landscapes generated by domesticated agriculture and physical and biological processes. Specifically, the paper reports on how tourists to the Kimberley region of Australia discriminate between their perception of hum...

Species richness gradients are ubiquitous in nature, but the mechanisms that generate and maintain these patterns at macroecological scales remain unresolved. We use a new approach that focuses on overlapping geographical ranges of species to reveal that Indo-Pacific corals are assembled within 11 distinct faunal provinces. Province limits are characterized by co-occurrence of multiple species ...

The Neighborhood Algorithm (NA) is a popular direct search inversion technique. For dispersion curve inversion, physical conditions between parameters Vs and Vp (linked by Poisson’s ratio) may limit the parameter space with complex boundaries. Other conditions may come from prior information about the geological structure. Irregular limits are not natively handled by classical search algorithms...
