Geophysics
research at the Bureau concentrates on developing multicomponent seismic
technology that can be used to better characterize geologic systems.
Research effort focuses on design of vector seismic sources, optimization
of data-acquisition and data-processing procedures, and unified interpretation
of P- and S-wave images. Researchers use 9-component (9-C) seismic
data whenever possible as these data allow all seismic wave modes
(P, SH, SV, C, fast-S, slow-S) to be used in subsurface imaging. Research
involving 3-C and 4-C seismic data is also a key focus area, even
though SH and SV modes are not available with these data, as 3-C and
4-C data are acquired by companies more often than are 9-C data. |
