designed facility, with 7500 sq. ft. of office and lab space
and 20,000 sq. ft. of warehouse space. This complex was
later expanded to accommodate USArray operations, adding
an additional 11,000 sq. ft. of office and lab space. The
building was designed by the PASSCAL technical staff and
NMT to optimize PIC operations. Land and construction
funds to build the original facility building and USArray
addition were entirely provided by the state of New Mexico
through the university.
Starting in 2002, the Department of Energy (DOE) provided
funds to replace the original six-channel and three-channel
data acquisition systems (DASs), which were becoming aged
and failure prone, with modern systems. The new DASs,
produced by REF TEK and Kinemetrics/Quanterra, incorporate
the latest technologies from the computer industry,
and as a consequence, require much less power, have higher
recording capacity than the first-generation instruments, use
modern memory components, and are configured to operate
with a number of communication systems as either serial
devices or TCPIP nodes. The preceding REF TEK 72a series
recorders have been officially retired from use. However, IRIS
and REF TEK are presently making these retired instruments
available to international partner institutions seeking to
establish or upgrade their permanent networks.

A major enhancement to US seismological resources and
increased activities at the PIC began in 2003 with the start
of EarthScope, a continent-scale, multidisciplinary project
funded under the NSF Major Research Equipment and
Facility Construction account. IRIS is responsible for the
operation of USArray, the seismological component of
EarthScope. With separate funding through EarthScope,
a Flexible Array, providing both broadband and high-frequency
instruments for individual PI experiments, operates
out of the PASSCAL instrument Center. Most Flexible Array
operational needs and procedures closely parallel those of
the core PASSCAL program. The largest part of USArray, the
400-element Transportable Array that will gradually cross
the conterminous United States and Alaska continent over
a 15-year period, is based on many of the technologies and
operational procedures developed by PASSCAL. A USArray
Array Operations Facility (AOF) at the PIC (funded through
a separate subaward to New Mexico Tech) supports the operation
of both the Flexible Array and the Transportable Array.
The AOF shares personnel and logistic support with the
core PASSCAL program, leading to significant leverage and
efficiencies for both programs. The AOF also acquires, tests,
and assembles primary field Transportable Array components.
A Transportable Array Coordinating Office (TACO),
located at the PASSCAL Instrument Center, but staffed and
operated as an independent USArray unit, is responsible for
many of the specialized logistic and siting activities required
in the operation of the Transportable Array. With EarthScope
support, a remote backup for the IRIS DMC archive has been
established at the PIC; office space is provided for a USArray
data analyst and two UNAVCO employees who provide quality
control for EarthScope PBO strain data.
