USArray Cascadia Initiative Robert W Busby TA Manager

USArray: Cascadia Initiative Robert W. Busby TA Manager Cascadia Science Planning Workshop LDEO June 29 -30, 2009 Palisades NY 1

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. 5 M, 3 -5 Yr O&M, 2010 mostly operational

TA-2 Cascadia • 25 Broadband Stations with 6 ch & 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 A spirited debate ensued, thanks to: • • • Mike Brudzinski PNSN: Paul Bodin, John Vidale Ken Creager Richard Allen USGS Menlo: David Oppenheimer, David Croker • BDSN: Peggy Hellweg, Barbara Romanowicz, Doug Neuhauser • More debate welcomed!

Budget Forming • Cost of Equipment • Cost of deployment • Operations: • • • Management Array Operation Facility Array Network Facility DMC Analysts Service Telemetry 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?

Notional Plan

Quarterly Plan 2013 2012

Alaska 200 stations 85 km station spacing Existing Stations: Aleutians Juneau Color scale depicts levels of permafrost 2015? 2014

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?

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 FA Style Deployments • Open data • Real time availability • Optimized for repeated execution • Monitoring and Picking • Service and Maintenance • Calibrations & Metadata provided • PI chosen focus • Custom Station & Array designs • Data locally collected • PI serviced and monitored • Data can be sequestered • Metadata supported
