Soil organic carbon prediction with terrain derivatives using geostatistics and sequential Gaussian simulation

Field Heterogeneity of Soil Organic Carbon and Relationships to Soil Properties and Terrain Attributes

Our objectives were to: (1) characterize SOC (0 to 1.53-m) within a 37-ha field typical of the Palouse region in eastern Washington; and (2) assess correlations and how much SOC variance could be accounted for by terrain and soil variables. A systematic, non-aligned grid of 177 georeferenced sample locations was established at the Washington State University Cook Agronomy Farm (CAF) near Pullma...

Assessing the risk costs in delineating soil nickel contamination using sequential Gaussian simulation and transfer functions

separation of saltwater and freshwater using sequential gaussian simulation in resistivity measurements

saltwater intrusion into freshwater in coastal areas has been a serious concern for many countries. providing fresh water in some regions is very crucial. in fact, the areas that  are prone to encountering salt water zones should be checked meticulously. the preferred method for such investigation is a precise 3-d model of distribution of fresh and salt water in order to reach such a model, rel...

Sparse, Sequential Bayesian Geostatistics

Biography Dr. Dan Cornford is a lecture in Computer Science and works in the Neural Computing Research Group at Aston University. Research interests are in the field of spatial statistics, space-time modelling and data assimilation. Lehel Csato is a post-doc in the same group working on an EPSRC grant (GR/R61857/01) looking at applying sparse sequential Gaussian processes to data assimilation. ...
