Standing Committee Meeting Report Instrumentation Services

November 2015

November 3-4, 2015, Martin Johnson House, La Jolla, CA

Action Items

Woodward/Anderson: Revise the Large N / Wavefields demonstration experiment proposal / slides with ISSC comments and send out another copy to the group, then present to the BoD.

Anderson: Discuss with vendor(s) options for trades or swaps of any current sensors ready for decommissioning now and/or in the future.

Detrick: Seek additional, informal information from NSF regarding constraints on decommissioning sensors.

Frassetto: Integrate PASSCAL equipment pool information into Sustainability Analysis slides for presentation to the BoD.

ISSC: Provide feedback on instrument sustainability analysis as part of spring meetings, in advance of final presentation to BoD. 

Woodward/Anderson/Aderhold: Make a markup of the QAWG charge and report back to ISSC.

ISSC: Add GLISN committee web page back on to the IRIS website.

ISSC: Seek BoD endorsement to form a working group on the format for active source data. If BoD endorses this path, then the relevant groups will work together on the charge (balancing near term and long term objectives, needs of different groups, etc.).

ISSC: IS would like to review and comment as part of the BoD approval process for new DS data policies.


Any new data policies (e.g., LDTD) should be published to community.

Invite chairs of the other IS committees as ex officio members and if they can’t attend having them recommend/delegate to another committee member to attend in their place. 

Short Meeting Summary

Large N - Discussed the timeline for the wavefield community experiment solicitation, implementation, and follow-up workshop. Developed process and timeline for the experiment.

Large N II  - The details regarding scope, timeline, and budget of the experiment were finalized.

TA L48 Sensors - STS-2s and T-240s are accounted for, Guralps are in two groups - 32 that are working and in reserve for AK TA currently, will be available around 2016; 36 that are on the shelf (having failed the three-strikes rule) that perhaps can be traded-in to Guralp.

Sustainability – The discussion addressed the question of sustaining the various sets of instruments within the facility, recapitalization, advancing capabilities in terms of our instrument pools. Will vet the overall plan through the various IS committees to deliver a integrated message to the BoD.

Instrumentation needs and specs – Updated GSN VBB vault sensor specs are in progress; MEMS sensors, Will work with USGS to develop specifications for next generation aftershock/rapid deployment sensors (e.g., next generation NetQuakes/QCN/MEMS).

Data Quality/QAWG – Discussed how to adapt the QAWG to encompass IS issues and concerns (per BoD guidance). Discussed the need for tools/scoring to deal with Big Data - research ready datasets.

Polar - Looking to international collaboration in order to meet costs for cutting-edge projects, GLISN would like more requests from ISSC and PNSC to progress goals.

MT – The small PI pool is limiting options for expansion. It is desirable to manage this more like seismological instrument pool. Discussed the status of data uploads and the data upload process.

CEUSN - Difficulties in describing what this network is (159 stations) versus what capabilities it provides within the regional networks. Depends on who the audience is (USGS, DOE, state geologists, public, government, etc.). Concern about the timing of this opportunity, need to make sure everyone knows how much has been invested into the network (~$12 million) and why it is so important to keep it going. CEUSN working group would like to keep in touch with IS and other committees in order to have feedback on the pamphlet and other future projects.

Large Datasets at DMC - Concern about the BoD making decisions that would affect the community and not broadcasting that information.

PH5 - The need for a more flexible data format for active source data, but there are a lot of perspective. Would like to form a working group of concerned parties to address the development of PH5 and to make sure that no one is affected negatively as it is implemented.

EPO - Status update and should keep that group in mind when putting together training/workshops, educational materials, etc.
