Thread: Long-Term Seafloor Seismographs SIG at AGU - Dec 13, 4 - 5:30 p.m.

IRIS is pleased to announce aSIG meeting on Long-Term Seafloor
Seismographs (LTSS) to be held at the
2017 AGU Fall Meeting in New Orleans.

The scientific needs of global and regional seismology require long-term
(2 to 5+ years, ~permanent), high-quality, telemetered seismic
observations from key seafloor sites in order to complement existing
high-quality permanent stations on land.

The LTSS SIG is scheduled for *Wednesday, December 13th from 4-5:30 pm*
*Dauphine I & II **rooms of the Hampton Inn & Suites / New Orleans
Conference Center*, and is being hosted by the WGLTSS (IRIS Working
Group on Long-Term Seafloor Seismographs)

This SIG will provide an opportunity for community members who are
interested in the deployment of "long-term" high-quality broadband
seismic stations on the seafloor. Planned topics of discussion include:

1. Review of current proposed and planned seafloor station or array
deployments, including length of deployments, relevant to long-term,
continuous monitoring.
2. Review of potential scientific targets and observations, e.g.
recording seismic phases, great earthquakes, etc.
3. How long does a site need to be continuously occupied to gather
enough relatively short-period mantle and core phase data from large
earthquakes?
4. Discussion of scientific observations that require deployments longer
than 18M1] <#_msocom_1>months.
    a) What can we observe over 5 years that we cannot observe over 18
months?
    b) What can we observe over 10 years that we cannot observe over 5
yearM2] <#_msocom_2>?
5) Pros and cons of short-term "arrays of stations" versus deploying one
high-quality station for a longer period of time.
6) What array configurations are needed to see the details of
large-scale deep earth structures that have been partially resolved with
global tomography?
*Those interested in attending are asked to reply to this message so
that we may get an approximate head count for catering and room setup.
 Responses before Thanksgiving would be greatly appreciated.*

Thanks, and we hope to see you there!
