Clearinghouse for seismic data
IEEE 1999 International Geoscience and Remote Sensing Symposium. IGARSS'99 (Cat. No.99CH36293), 2003Availability and multiple use of seismic data and derived crustal models are necessary for the success of interdisciplinary collaboration. The German continental reflection seismic program (DEKORP) investigated more than 4500 kilometers of seismic profiles. This data collection is a unique and valuable scientific asset.

An investigation of low-rate seismic data compression using transform techniques is presented. This study concentrates on discrete orthogonal transforms such as the discrete Fourier transform (DFT), the discrete cosine transform (DCT), the Walsh-Hadamard transform (WHT), and the Karhunen-Loeve transform (KLT).

As we rewrite the seismic data processing and interpretation programs to account for the true vector nature of the seismic data, we are able to extract more types of data and see further into the background noise. Examples of the extra types of data have been published by many authors: Amplitude vs Offset (AVO) Technology (Ostrander, 1982; Gassaway and

Seismic imaging is one of the most common geophysical techniques for hydrocarbon exploration. Seismic acquisition is a trade-off between economy and quality. In conventional acquisition, the time intervals between successively firing sources are large enough to avoid interference in time.

AbstractA layer‐by‐layer waveform inversion method is developed to derive the velocities of a multi‐layered model. Firstly, one new concept, medium perturbation‐response, is introduced and the gradient method for waveform inversion is analysed. Essentially, waveform inversion is to extract residual structural information between the real earth and ...

Abstract : The report summarizes the work done by the SDL during the period April through June 1973, and primarily concerns the seismic research activities related to the detection and identification of nuclear explosions and earthquakes. The report also contains brief discussions of the support tasks and data services which were performed for other ...

In this chapter, I presented seismic data that was made available for analysis and interpretation. This data originated from four mines: El Teniente Diablo Regimento Sector (DR Sector), Northparkes Mines Lift 2 (NPM), PT Freeport Indonesia DOZ Mine (DOZ) and Palabora Mining Company (PMC).
