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...

– Large scale geophysical prospection of an archaeological landscape in the Netherland. Integrated and multimethodological approach for interpretation. Challenges prospecting interpretation multiperiod sites.

Geophysical phenomena of interest to geoscientists include both atmospheric and terrestrial related processes, which can be either static or dynamic. Characterization of such phenomena requires advanced models which often include scale invariance concepts of fractal or multi-fractal type. Recently, there has been much interdisciplinary interest in the application of geophysical processes. The a...

Conservationists need methods to conserve biological diversity while allowing species and communities to rearrange in response to a changing climate. We developed and tested such a method for northeastern North America that we based on physical features associated with ecological diversity and site resilience to climate change. We comprehensively mapped 30 distinct geophysical settings based on...

The World Data Center for Geophysics in Boulder, Colorado is hosted by the National Geophysical Data Center (NGDC). NGDC’s vision is to be the world's leading provider of geophysical and environmental data, information, and products. NGDC's mission is to provide long-term scientific data stewardship for geophysical data, ensuring quality, integrity, and accessibility. Faced with ever expanding ...

Over the last two decades, several advances have been made in the development and application of slim-hole geophysical sondes for use in groundwater, engineering, and environmental applications. This equipment is commonly used to provide qualitative (but detailed) estimates of grain size, sediment type, porosity, density, pore-water salinity, as well as bulk and shear moduli, to supplement geol...

My research efforts to date have combined both theoretical and observational aspects of geophysical fluid dynamics. Specific topics that I have investigated include: large-scale ocean dynamics and thermodynamics; geophysical waves and flow stability (spectral, formal, and nonlinear); Hamiltonian geophysical fluid dynamics; nonintegrable Hamiltonian dynamics; passive tracer transport and mixing ...
