Worlds Collide through Gaussian Processes: Statistics, Geoscience and Mathematical Programming
Gaussian process (GP) regression is the canonical method for nonlinear spatial modeling among the statistics and machine learning communities. Geostatisticians use a subtly different technique known as kriging. I shall highlight key similarities and differences between GPs and kriging through the …

Data expertise and service development in geoscience data centers and academic libraries
… expertise and services, comparing approaches in geoscience data centers and academic libraries. Case studies of two exemplar sites are presented based on evidence from qualitative interviews and artifact collection. The case studies are extended and further informed through qualitative interviews …

Modelling Three-dimensional Fields in Geoscience with the Voronoi Diagram and its Dual
The objects studied in geoscience are often not man-made objects, but rather the spatial distribution of three-dimensional continuous geographical phenomena such as the salinity of a body of water, the humidity of the air or the percentage of gold in the rock (phenomena that tend to change over …

Partitioning of fluid flow along faults and fractures in the Bristol Channel Basin: implications for low carbon geoscience projects in SW England
The Bristol Channel Basin (BCB) is a Mesozoic continental rift basin and an important<br/>analogue for offshore reservoirs. Previous studies have used relative cross-cutting<br/>relationships and correlations with adjacent sedimentary basins to constrain its<br/>development. For the first time, …

Underground Britain: public perceptions of the geological subsurface
Geoscience operates at the boundary between two worlds; the visible and the invisible. Increasingly, new geological technologies such as hydraulic fracturing, carbon capture and storage (CCS) and radioactive waste disposal are drawing the public’s attention to the ‘invisible’ world of the …

A Space of their Own? A feminist exploration of gendered spatial relations in Professional Women’s Organizations in Alberta's Resource Sector
Throughout the life cycle of a geoscience career gender inequalities still exist, even in the face of legislative change. One response in Alberta is the formation of professional women’s groups. Drawing on feminist geography, the objective of this research was to explore the social relations and …
