[OBSIPtec] IRIS Working Group on Long-Term Seafloor Seismographs Requests your Input

[Katrin Hafner]

Dear Member of the Global Seismology community,

The *I**RIS GSN Working Group on Long-Term Seafloor Seismographs* 
(WGLTSS <https://www.iris.edu/hq/about_iris/governance/wgltss>) invites 
you to participate in a short survey related to questions in global 
seismology and allied disciplines that can be addressed by future 
long-running seafloor seismic stations. Last December at AGU, this 
working group held a *Special Interest Group meeting* 
<cid:part2.34A7FD91.45076A58 at iris.edu>to discuss the scientific targets 
and associated data needs from seafloor seismographs. The goal of the 
SIG was to gather community input in order to provide guidance on 
designing a pilot experiment to deploy long-term seismographs on the 
seafloor.

As a result of discussion at the SIG, we have designed this short survey 
in which we ask for your participation. In this survey, you will have an 
opportunity to articulate (up to) three unanswered questions where 
significant advancement could be made with up to five new, long-term 
seafloor seismometers or small-aperture seafloor arrays. Questions can 
include unsolved problems in seismic structure, tectonic evolution, 
geodynamics, composition, magnetic field, earthquake source processes, 
or other relevant disciplines that require seismic data from 
long-running seafloor stations as a direct constraint.

Please consider filling out the survey at:

https://www.surveymonkey.com/r/288KP9P

We anticipate it will take approximately 15 minutes to complete.  Your 
community input will be directly relevant to a pilot experiment design.  
The survey will be available until *March 19th, 2018*.

Kind Regards,

Monica Kohler (Chair of the WGLTSS)
Jeffrey Park (Chair of the GSN Standing Committee)
Katrin Hafner (IRIS GSN Program Manager)
