Passing of Former PASSCAL Program Manager Jim Fowler

Jim Fowler passed away on February 25, 2014 after a lengthy battle with cancer and Parkinson’s disease. Jim began his career at IRIS consortium (Incorporated Research Institutions for Seismology) in 1985 as Chief Engineer in Washington, DC, and later became the first manager for the PASSCAL portable instrument program. In 1999, after New Mexico Institute of Mining and Technology was selected to operate the IRIS/PASSCAL Instrument Center, the nation’s sole lending library for research seismological instrumentation, Jim moved back to his home state of New Mexico. Jim stepped down as the PASSCAL Program Manager in October 2010 after 25 years in that position, but continued as Senior Advisor for Engineering and Instrumentation until he retired in February 2013 and moved back to Maryland.

Getting It Perfect at OIINK

Gary Pavlis and Terry Stigall of Indiana University are proud of their geophysics students. The students were helping them to deploy some new direct-burial stations with Trillium broadband sensors for the OIINK project (a.k.a. SDYNAC, "Structure and Dynamics of the North American Craton"), and Terry directed them to get them perfectly level and lined up to north accurately. The students outdid themselves, and helped to make this a superb installation.

These students are from Gary Pavlis' Applied Geophysics class. They spent a weekend installing stations for the OIINK project.

RefTek GPS Alert


Dear PASSCAL Users:

This note is to alert all past and current users of RefTek RT130 hardware that these instruments have been experiencing GPS failures in-field. To date, the failures are geographically confined to East Africa and symptoms include intermittent or total loss of timing.

It is worth noting that in reviewing close to two years of repair records, 1303 GPS have been returned to PIC from 69 experiments, excluding those in East Africa, and the total number of GPS units that needed any type of maintenance or repair was 30. There is no evidence at this time that there is a global problem with our RefTek GPS.

We are recommending that all users of PASSCAL RefTek RT130 dataloggers review their data and log files for signs of GPS failure that are consistent with the failures seen in East Africa. To identify failure behavior please visit this page for a brief tutorial. If you identify failures in your data, please contact passcal [at] passcal [dot] nmt [dot] edu and include "RT130 GPS failure" in the subject line and unit serial numbers in the body of the email.
