New!!! OpenSeaSeis Release 2.0

The popular open source seismic workflow generator and seismic viewer SeaSeis, developed by Bjorn Olofssen, has been donated to the Colorado School of Mines, and is now OpenSeaSeis! OpenSeaSeis.

SLT/SU: Seismic Laboratory Tools (or SugarLand Texas) written in SU-style

The SLT/SU: Seismic Laboratory Tools package is the work of a number of geophysicists, including Zhiming Li, Rick Ottolini and Reg Beardsley. Through the generosity of Chevron, these codes have been donated to the Colorado School of Mines and the Center for Wave Phenomena for general distribution in the hopes that the codes will prove useful to students and research scientists everywhere. Our ultimate goal is to absorb the greater part of SLT/SU into the regular SU package.

The package will install as is on a number of platforms. These codes were based on an earlier version of CWP/SU, so there is some overlap with the CWP/SU. Also, there is mixed-language (F77 and C) programming, which may reduce portability. The SLT codes are distributed under the same licence Legal Statement as the regular SU package.

BHP_SU: SU-style codes developed by BHP Billiton

The BHP_SU package was written largely by Michael Gilinsky at BHP Billiton, as part of an innovative open-source software project sponsored by BHP. BHP has graciously allowed these codes to be distributed by the Colorado School of Mines.

Potash SU: SU-style codes developed by Balazs Nemeth

Potash SU: Additional SU style codes were written by Balazs Nemeth and given to the Colorado School of Mines by the Potash Corporation in Saskatoon, Saskatchewan, Canada. Our ultimate goal is to absorb Potash SU into the regular SU package.

The package has a Makefile, but it is not expected that users install the package. This collection is offered as raw material for software developers. The Potash SU codes are distributed under the same licence Legal Statement as the regular SU package.
