A non-hydrostatic code that numerically solves the unsteady, three-dimensional, primitive equations is used. Advanced models such as the dynamic mixed model and the dynamic eddy viscosity model are utilized to represent subgrid processes in the LES approach. A novel near-wall model has been developed so as to increase the Reynolds number of boundary flows to realistically large geophysical valu...

In this report we introduce the development of the WDC for Geophysics, Beijing included our activities in the electronic Geophysical Year (eGY) and in the transition period from WDC to WDS. We also present our future plans. We have engaged in the development of geophysical informatics and related data science. We began the data visualization of geomagnetic fields in the GIS system. Our database...

Geophysical Prospection has yielded remarkable results to the research in Archaeology. Besides the recognition of places, also the earlier uses of a site can be reconstructed. Therefore, the geophysical techniques help to understand the layout of a site and raise new research questions. In this paper, we summarize the main geophysical prospection methods for archaeology: magnetic, radar and res...

We present and study the stability, convergence, and order of convergence of a numerical scheme used in geophysics, namely, the stochastic version of a deterministic “implicit leapfrog” scheme which has been developed for the approximation of the so-called barotropic vorticity model. Two other schemes which might be useful in the context of geophysical applications are also introduced and discu...

When conducting an investigation of the subsurface a geoscientist will often locate specific borehole geophysical data for the area of study. This process of locating spatially where the geophysical logs have been conducted and what specific parameters have been run in each logging suite can often be difficult and take the investigator several hours or even days depending upon the size of the s...

Lunar Science: The Moon provides a unique opportunity to study fundamental questions about the origin and evolution of the inner solar system. While it is widely believed that the Moon was created by the collision of a large object with the Earth during early planetary formation, this has not been conclusively proven. Furthermore, the mechanisms and processes by which this may have occurred are...

[1] The electrical conductivity of mantle minerals is highly sensitive to parameters that characterize the structure and state of the lithosphere and sublithospheric mantle, and mapping its lateral and vertical variations gives insights into formation and deformation processes. We review state‐of‐the‐art conductivity models based on laboratory studies for the most relevant upper mantle minerals...

We present statistical and interval techniques for evaluating the uncertainties associated with geophysical tomographic inversion problems, including estimation of data errors, model errors, and total solution uncertainties. These techniques are applied to the inversion of traveltime data collected in a cross well seismic experiment. The inversion method uses the conjugate gradient technique, i...
