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...

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 ...

Busstop, a spatio-temporal GIS prototype for geophysical studies, is presented. It includes a metadata representation system, a visualisation subsystem, and a spatio-temporal extension of a classical map algebra. It also takes an active approach to integration with existing non-GIS data handling and analysis programs. Busstop has been used for minor geophysical case studies with some success, b...

Geophysical survey methods bring information on the rock environment in real time, i.e. already during the geophysical survey. A geologist or a geotechnician provides such obtained information to a designer for the purpose of designing and implementation work at construction sites. Also, information on the effect of the rock environment or its properties (changing with time) on stabilization wo...

A series of digital data sets were compiled for input into a geophysical data base for a one degree quadrangle in Arizona. Using a Landsat digital mosaic as a base, information on topography, geology, gravity as well as Seasat radar imagery were registered. Example overlays and tabulations are performed. The role of remote sensing in environmental inventory has evolved into an important supplem...

the study area covers the northern part of the baft geological map (scale of 1:100 000 ). several porphyry and vein-type mineralization are reported from this area. a topic that is discussed in the mineral exploration community is the use of remote sensing and airborne geophysics for porphyry type mineralization. which one is more reliable and efficient in hydrothermal alteration mapping? airbo...
