PASSCAL Facility

The Incorporated Research Institutions for Seismology (IRIS) Portable Array Seismic Studies of the Continental Lithosphere (PASSCAL) Instrument Center and EarthScope USArray Array Operations Facility (AOF) at New Mexico Tech support cutting-edge seismological research into Earth’s fundamental geological structure and processes. The facility provides instrumentation for National Science Foundation, Department of Energy, and otherwise funded seismological experiments around the world. PASSCAL experiment support includes seismic instrumentation, equipment maintenance, software, data archiving, training, logistics, and field installation.

Continued expansion of IRIS activities at New Mexico Tech via the EarthScope and other initiatives has spurred a major facility expansion, the EarthScope USArray Array Operations Facility. The AOF was officially dedicated on April 6, 2005 by the New Mexico Tech administration and the IRIS Board of Directors. The combined PASSCAL Instrument Center and AOF currently support a total of 33 professional New Mexico Tech staff, as well as a contingent of student workers.

PASSCAL and USArray Flexible Array equipment is available to any research or educational institution to use for research purposes within the guidelines of established policies. These policies provide that data collected with PASSCAL and/or USArray equipment be archived at the IRIS Data Management Center and that the data are openly available to the community. Instruments can be requested online using the PASSCAL Instrument Request Forms.

PASSCAL Workshop: Data Archiving and More!

Sunday, December 13, 2015
San Francisco - Zelos Hotel

An IRIS PASSCAL workshop will be offered prior to the 2015 AGU Fall meeting in San Francisco. This workshop will cover the topics of SEED data archiving using Antelope, instrument responses and what they mean, and active-source data with PH5 in the field and from your desktop.  It will also serve as an opportunity to help PIs and archivers familiarize themselves with the PASSCAL Data Group and the support they provide, and the software utilized in the archival process.

RT130 ALERT - Issue when using two 4GB CF cards

Jan. 5, 2015

PASSCAL recently received reports of RT130’s failing when using two RefTek 4G CF cards at moderately low temperatures during an Antarctic experiment. We have duplicated the failure in our lab and in our testing the failure was associated with a specific version of RefTek well board (RT526D). Although we have not had failures in our testing with earlier or later versions of the board, our sample set is small and we cannot rule out problems with these boards when using two 4G CF cards. We have communicated with RefTek about the issue and at this time they are in agreement with these findings.
