Introduction
• Feb 09: At NSF request, USArray submitted
several ideas for consideration of ARRA
funding, including redeploying TA in Cascadia.
• April 09: NSF suggested a framework for
linking a few specific ideas from PBO, USArray
and OBSIP.
• May 09: facility program preliminary plan due
“Redeploying the TA in Cascadia”, Guidance:
$2.5M, 3-5Yr O&M, 2010 mostly operational
TA-2 Cascadia
• 25 Broadband Stations with
6ch & telemetry
• Permit, construct, install
• Operated for 5 years
• Data Collection via ANF to
DMC—open data, real time.
• Picks and Data QC provided
• Includes Strong Motion
Sensors
TA-2 Cascadia
Factors in Station Location
• Existing Broadband Stations
PNSN, BDSN, GSN, ANSS
• Planned upgrades to Crest,
PNSN or BDSN
• Good Quality TA stations
with existing vaults
• Good Quality FA stations
• Where’s a gap?
TA-2 Cascadia

Given a bottom Line and a period of performance,
we solve for number of stations
We’ve made no plans as to what happens next,
Removing the stations is an additional $132,000
Shovel Ready!
Schedule Details:
• Preliminary Project Plan
•
•
15 stations by Sept 30 2010
10 stations by Dec 31 2010
• Possible Scenarios
• 10 stations Oct 2009
• 15 stations June 2010
• End of 5 year O&M is
2014-2015
• Monitoring ASAP or in
conjunction with OBS?

Data Integration
• What are the plans to integrate the data
from onshore and offshore
instrumentation? Is there a DCC
involved?
• Is this a deployment based task or a
facility based task?
IRIS & USArray
“Iris is sponsered by NSF …dedicated to the operation of scientific facilities for
the acquisition, management, and distribution of freely available seismic data.

USArray Options
TA is operated by IRIS as a broad community resource, with a specific, defined
implementation target and immediate community access to data.
FA is a collection of instruments for use by PI's in experiments which they define.
TA Style Deployments
• Open data
• Real time availability
• Optimized for
repeated execution
• Monitoring and
Picking
• Service and
Maintenance
• Calibrations &
Metadata provided
FA Style Deployments
• PI chosen focus
• Custom Station &
Array designs
• Data locally collected
• PI serviced and
monitored
• Data can be
sequestered
• Metadata supported
