We are looking for a PhD student that employs advanced geostatistical methods for spatial interpolation of soil and agronomic variables. Bayesian (hierarchical) geostatistical modelling has recently been developed for spatial prediction of environmental variables using multiple sources of information, such as point observations, spatially exhaustive covariates, legacy data sets and maps, and output of mechanistic models. Bayesian geostatistics is attractive because it can accommodate a broad category of problems and is perfectly suited for handling multiple sources of information. So far there have been very few applications in soil science and agronomy, while it has much potential for digital soil mapping and yield gap mapping.
The successful applicant will: 1) become an expert in Bayesian hierarchical geostatistics, both from a statistical and software-implementation perspective; 2) extend Bayesian geostatistics so that it can handle spatial scale differences between observations and predictions; 3) apply Bayesian geostatistics to digital soil mapping in the Netherlands (updating parts of the 1:50, 000 scale Dutch soil map, and Africa (produce 3D soil property maps for focus countries of the AfSIS project, 4) apply Bayesian geostatistics to scale up yield gap information collected at experimental farms and sites to serve the global yield gap atlas Field visits to case study areas for collection of validation data are anticipated.
We ask for a candidate with an MSc degree or equivalent in statistics, soil science, agronomy or environmental sciences. The successful candidate must have a proven affinity with application of statistical methods in the earth and environmental sciences, and must not be afraid to dig into the statistical details. At the same time, he or she must be motivated by real-world applications of statistical methods. We also expect a very good level of English, experience with computer programming (preferably R), strong communication skills and ability to work in a team.
We offer a fulltime employment (38 hours per week) as PhD researcher within the Soil Geography and Landscape group for 18 months with a possible extension of 30 months after a positive evaluation. The gross salary will increase from € 2083 per months in the first year up to € 2664 per month in the fourthe year (based on fulltime employment). In addition, we offer a holiday bonus of 8% and an eind-of-year bonus of 8.3% of your annual salary.
Dienstverband: Temporary, Onbekend
This PhD project is a cooperation between the Soil Geography and Landscape group of Wageningen University, ISRIC - World Soil Information and the Soil Geography team of Alterra.
The Soil Geography and Landscape group of Wageningen University aims to contribute to sustainable soil management in a landscape context. Our mission is to improve and share understanding of patterns and dynamics of soils and landscapes. We take an integrative approach that combines biophysical and human elements to gain insights in past, present and future system dynamics and to support sustainable land management.
Anything new about stirling engines in Cal?
Looking for an update. Everything I find from google news is almost a year old. This is from the stirling engine deal with Southern Edison to build a 500MW plant outside of LA.
What geographical areas are best suited for a solar dish farm?
The southwest region of the United States is ideally suited for this. In fact, a solar farm 100 miles by 100 miles could satisfy 100% of the Americaâs annual electrical needs. Solar technology primarily addresses the peak power demands facing utility companies in the Southwest U.S. and other solar-rich areas.
The cost of living and job markets are better than the national average, but the best job strategy is not to go for averages, but look at your specific skills and experiences, figure out which careers that relates to, and then go to that geographical area:
technology - Silicon Valley
finance - New York
There are other factors to consider. How important are mountains? the ocean? good weather? I have met many midwesterners in Acapulco during the winter, and none ever told me
"I got to get back to Omaha. I just miss those snow covered plains."
4,000 Year Old Greenlander
WASHINGTON (Reuters) â Scientists have sequenced the DNA from four frozen hairs of a Greenlander who died 4,000 years ago in a study they say takes genetic technology into several new realms.
Surprisingly, the long-dead man appears to have originated in Siberia and is unrelated to modern Greenlanders, Morten Rasmussen of the University of Copenhagen and colleagues found.
"This provides evidence for a migration from Siberia into the New World some 5,500 years ago, independent of that giving rise to the modern Native Americans and Inuit," the researchers wrote in Thursday's issue of the journal Nature
