Education and Public Outreach at PASSCAL - French School Visit

On Friday, November 1st 2013, a group of students and teachers from Bethesda, Maryland's Lycée Rochambeau/ French International School visited the IRIS/PASSCAL facility on Socorro NM for some hands-on demonstrations of how seismic measurements are used to "see" geological strata underground.  The class, led by instructor Marc Roux, head of the Biology and Geology Department, were assisted by PASSCAL scientists Greg Chavez and Michael Johnson during the deployment of a long string of geophones and a multi-channel data acquisition system.  The students then used heavy hammers to produce active source tremors, and then were able to see the seismic responses in real time.  The class assembled in the PASSCAL conference room to hear PASSCAL scientists/data specialists Dr. Wallis Hutton and KatyLiz Anderson discuss how such measurements can be used to find the depth of subsurface structures like the Moho.  The visit was capped with a tour of the PASSCAL facility, led by scientist/software engineer Dave Thomas.

Nature Magazine Marks Transportable Array Milestone

A November 5th article in the prestigious journal Nature discusses a major milestone in the Transportable Array project. In her article "US seismic array eyes its final frontier," Nature's Alexandra Witze writes

On Maine’s rugged coast, just north of the tourist town of Boothbay, an underground seismometer is listening for earthquakes. Engineers activated it on 26 September, completing the US$90-million Transportable Array, an ambitious effort to blanket the contiguous United States with a moveable grid of seismic monitors ... "As the array has moved, the whole picture of what’s under North America has gotten much sharper," says Andy Frassetto, a seismologist at the Incorporated Research Institutions for Seismology (IRIS) in Washington DC, which operates the stations.

P.I. Transition coming to the IRIS/PASSCAL Instrument Center

After 15 years of shepherding the IRIS PASSCAL Instrument Center as Principal Investigator, Rick Aster will be leaving NM Tech to begin a new phase of his career at Colorado State University as Geosciences Department Head, beginning in January of 2014. Principal Investigator duties will be assumed by Susan Bilek, Associate Professor in the Department of Earth and Environmental Science beginning October 1, 2013. After moving to Colorado, Rick will remain engaged with IRIS as an active community member and as Chair of the Data Management System Standing Committee, and will continue to interact with Sue, NM Tech, and the Instrument Center on continuing projects and as a user of IRIS facilities for Antarctic and other research.

IRIS/PASSCAL Intern Caps Busy Summer with Alaska Deployment at Poker Flat

It's been a busy summer for IRIS/PASSCAL intern Kasey Aderhold, a PhD Candidate at the Department of Earth & Environment, Boston University. Kasey has been heavily involved in an ongoing comparison of seismic vaults to direct burial installations at two sites: the Dotson Ranch near Socorro, NM, and Poker Flat in Alaska. 

 

Seismic Community Gathers for SITS

The 2013 Seismic Instrumentation Technology Symposium (SITS) was held in Albuquerque, NM on June 10th and 11th, 2013.  The well-attended symposium provided a splendid opportunity for members of the seismic community to exchange knowledge on instrumentation, as well as on novel approaches for improving the usefulness of data.

EarthScope/TA Featured on the Weather Channel

The EarthScope/Transportable Array program was highlighted on the Weather Channel in an April 26th report by correspondent Dave Malkoff, titled "A CT Scan for the Earth." The segment included the actual installation of an EarthScope/TA vault in Virginia, and featured appearances by several EarthScope/TA team members, a discussion on the need for computerized tomography of the earth's interior, and an animation of the effects of Hurricane Sandy as seen by the Transportable Array.

Seismic Instrumentation Technology Symposium coming to Albuquerque on June 10-11, 2013

The next Seismic Instrumentation Technology Symposium (ITS2013) will be held in Albuquerque, NM on June 10th and 11th, 2013, at the Sheraton Albuquerque Airport Hotel.

The IRIS website has a page for the conference, with the agenda, participants, and registration form.

The theme of this symposium is to examine future technology, both from the perspective of capabilities scientists and engineers are seeking and the technologies that are, or will be, in the product pipeline of the seismic technology industry. The symposium will provide a forum for perspectives from both technology users and vendors and allow generous time for discussion and interaction.

PASSCAL Staff in the News

It's been an eventful media week for several of the staff of IRIS PASSCAL, who were highlighted in a lengthy piece on women in science in the New Mexico Rural Electric Cooperative Association's magazine, enchantment, which is the second largest publication in New Mexico. Then, when a small earthquake rocked Socorro, more PASSCAL staff were prominently featured in a report on the quake in the local newspaper of record, El Defensor Chieftain.

Freshman Senator Visits IRIS/PASSCAL

On Friday, February 22nd, New Mexico's newest member of the United States Senate, Martin Heinrich, paid a visit to New Mexico Tech, and the IRIS/PASSCAL Instrument Center. Senator Heinrich, who won his seat in the 2012 general election, is a strong advocate for Science, Technology, Engineering, and Mathematics (STEM) Education, and is the only engineer currently serving in the senate.

Senator Heinrich was given an overview of activities at the school by New Mexico Tech President Dr. Dan Lopez, and also toured the Mechanical Engineering Department.  Dr. Rick Aster escorted Sen. Heinrich on a tour of the PASSCAL Instrument Center, the world’s largest and the nation’s flagship federally-funded lending library of seismology equipment.

IRIS PASSCAL Supports Fluvial Seismology Research in Grand Canyon

When and how do rivers transport sediment from eroding landscapes? New research by Brandon Schmandt and Karl Karlstrom of the University of New Mexico and Rick Aster of New Mexico Tech is shedding light on how seismology can address this fundamental problem. The PASSCAL Instrument Center provided several quick-deploy stations from its RAMP (Rapid Array Mobilization Program) pool in support of this innovative project. The panoramic view of the Grand Canyon above was taken during a December 2012 data recovery trip.
