The combination of preliminary DEM analysis, field studies and the mapping of subsurface structural elements proved to be successful in separating landforms developed under or in absence of neotectonic control.
Accurate 2-D and 3-D reconstructions and maps of the subsurface are needed in hydrostratigraphy, hydrogeology and geotechnical studies.
(About a third of Shell's capital spending goes to North America). The tools of the trade have grown more sophisticated over time, with computer-aided seismic surveys that can give exploration companies detailed three-dimensional, multicolored maps of the subsurface.
The stations will collect seismic data for two years, which will be used to create a map of the subsurface in the area that can be used for interpretation.
"We search the map for a positioning match based on the rough GPS location and the speed of the vehicle". Once a GPR has scanned an entire roadway, it creates a map of the subsurface strata that can determine the location of a vehicle within a few centimeters.
The high power solar arrays that power the Xenon ion engines can also power a radar which could provide a global map of the subsurface ice on Mars.
Another main thrust of research activities based at M.A.R.S. pertains to the detection, mapping, and quantification of subsurface ice deposits.
In particular, the potential of the low frequency domain (1 2 GHz) of L-band spaceborne SAR, when compared to applications of shorter wavelengths of C, S and X band SAR, is obvious for the purpose of subsurface mapping.
In the central Atlantic, for example, the maps show a huge slug of subsurface seawater with lead levels higher than those in surface or deeper waters.
An iterative loops have been used between the reservoir static model and dynamic well-test data to optimize the generation of subsurface fracture maps.
