IRIS/PASSCAL Facility featured on KRQE News 13

The IRIS/PASSCAL Instrument Center was featured in a three-minute video aired on August 22nd, 2016 by Albuquerque, NM station KRQE-TV-13. The video, which included segments on other New Mexico Tech research facilities (EMRTC, Langmuir Lightning Lab, the Magdalena Ridge Observatory, and at Mt. Erebus in Antarctica) can be seen here.

Tutorial on PASSCAL's New Instrument Request Form and PI Home Page

In June 2016, PASSCAL implemented a new version of the Instrument Scheduling Database.

This tutorial shows Principal Investigators how to request an account, how to log in, how to use the PI Home Page, and how to submit a new and/or modify an existing Instrument Request.

Important Update to rt2ms

Important update to rt2ms program for processing RT130 data

This is to inform you about an important software update needed for processing of Reftek RT130 data in PASSCAL experiments. We recently discovered an issue with running rt2ms on the second card installed in the RT130.  Sometimes insufficient header values are being written by the RT130 and then rt2ms passes over these packets potentially resulting in a gap on one or more channels (typically less than 1 hour on higher sample rate data, larger gaps on 1sps data).  The PASSCAL Software Group has patched rt2ms to handle the missing packet headers and write all of the data that are on the card.  We highly recommend that you download and install the updated rt2ms program if you are processing any RT130 data.

Bighorn Arch Seismic Experiment: Results

In 2010, a group of seismologists deployed several hundred sensors across Wyoming and Montana as part of EarthScope's Bighorn Project and the Bighorn Arch Seismic Experiment (BASE). IRIS/PASSCAL supplied instruments and expertise as part of this large effort, which included scientists from CIRES at University of Colorado Boulder(1), the Department of Geology at Colorado College(2), the Department of Geology and Geophysics at the University of Wyoming(3), and the Department of Geology and Geophysics at Texas A&M University(4). The Principal Investigators included Anne F. Sheehan(1), Megan L. Anderson(2), Eric A. Erslev(3), Kate C. Miller(4), and Christine S. Siddoway(2). William L. Yeck(1), the lead graduate student from UC Boulder, provided analysis and support included in this article. Additionally, numerous students contributed to the effort. The team's recent publication, "Structure of the Bighorn Mountain region, Wyoming, from teleseismic receiver function analysis: Implications for the kinematics of Laramide shortening," is available from AGU Publications (Full, PDF).
