Posters,Special Interest Groups & Pre-Workshop Symposia

Posters and Science Highlights

Poster boards are 8' wide x 4' high and will remain up throughout the meeting. Poster assignment information will be available at the Registration table in Meadow Lobby beginning at 3pm on Tuesday, June 12. You may begin to hang posters after 3:00pm on Tuesday. Posters need to be removed by 2:00pm on Friday.

Workshop participants are encouraged to submit Science Highlights and present posters on IRIS-facilitated research and on topics related to the oral plenary sessions. Posters will be displayed in the ballroom at the Convention Center, which is large enough for all of the posters to remain up for the entire Workshop. Break refreshments will be served in the ballroom and the agenda will include times devoted exclusively to poster presentations. Posters on related topics will be clustered and scheduled for authors to be available for discussion at the same time.

To present a poster at the 2012 IRIS Workshop, you must submit a Science Highlight by May 4. IRIS will use the Science Highlight title and author information for the poster information to be published in the Workshop program.

The Science Highlights will also be stored and prominentaly displayed from IRIS' homepage, presenting an opportunity to share with all the broad and exciting body of work produced by the IRIS community. This virtual archive will serve as a resource to peers within the geoscience community, science directors at the National Science Foundation, and the general public. We encourage members of the IRIS community to contribute scientific, educational and outreach highlights to our gallery of IRIS-enabled accomplishments.

Special Interest Group (SIG) Meetings

Wednesday

Next-Generation Instrumentation for Portable Seismology - Seth Moran, James Gridley
While the IRIS 2013-2018 proposal includes a commitment to sustaining the existing PASSCAL and USArray pools of broadband, Texan, and multichannel sensor/digitizer packages, the portable pool also has limitations in terms of the types of experiments it can support. In this SIG we will discuss the science drivers for a new style of experiment involving tight spatial arrays of large numbers (“Large N”) of intermediate-period (10-30s) sensors. Presentations will include summaries of discussions to date and preliminary results from an ongoing trade study, followed by community discussion of objectives and requirements.

Resources for Undergraduate Teaching in Seismology - Maggie Benoit & Michael Hubenthal
What are the latest curricular materials available to teach seismology at a variety of undergraduate levels? What topics or resources (e.g. software, DMS tools, data sets) would you like to see developed into activities for your students? This SIG will include an overview of some of the most recently developed activities designed to be integrated into your existing courses, while also conveying the latest seismological research to your students. This will be followed by a discussion focused on eliciting feedback regarding new curricular activities that will be developed through both IRIS and the Pearson Higher Ed group. This is your chance to have an impact on the materials that will be available in the future.

GSN Data Quality - Kent Anderson, Tim Ahern
The GSN network is two years into a major quality initiative to improve the state of the GSN dataset. This work has included the continued upgrade to the GSN field systems and infrastructure, calibration of the GSN seismometers, review and update to the station metadata, and the implementation of an updated Quality Assurance System to identify, document, rectify and report data issues to the network operators and the GSN data user community. In conjunction with the GSN effort, the DMS is revamping its data quality tools to improve and expand the metrics available to assess the quality of the overall IRIS data holdings. This SIG will provide an update to both the GSN Quality Assurance System and the DMS Quality assessment tool development.

Thursday

Global Array of BroadBand Arrays (GABBA) - Chuck Ammon, Thorne Lay, Keith Koper
Important research questions related to Earth's deep interior and complex earthquake faulting processes are difficult to resolve with present day configurations of global seismic networks. However, significant progress can be made using medium-aperture (150 km x 150 km to 300 km x 300 km) broadband arrays, if the number of such arrays around the world with strategic locations can be increased, with operational lifetimes of a decade or more. This SIG will explore this concept for expansion of IRIS instrumentation supporting global seismology, recognizing that strong international partnerships will be essential to achieving a system with on the order of 10 GABBA nodes around the world. We invite short contributions on research applications that have utilized current broadband arrays and dense networks of stations (from regional networks, PASSCAL deployments, etc.) of dimensions comparable to the GABBA notion, as well as contributions on complementary value of deploying additional short-period arrays around the world. We also seek to identify a GABBA working group that can advance this concept and serve as a workshop steering committee that IRIS may support in the Fall of 2012 to explore development of a proposal to augment global seismic observations with GABBA.

Seismo-Acoustics - Brian Stump, Michael Hedlin, Stephen Arrowsmith
With the addition of both barometers and infrasound gauges to the Transportable Array a rich source of atmospheric pressure data is now available in consort with seismic data. These data are providing the ability to study sources of both seismic and acoustic energy such as shallow earthquakes, ocean storms as well as man made sources such as explosions. The data provide the opportunity to not only characterize these sources but also quantify the time varying nature of the atmosphere as well as constrain sources in the atmosphere that primarily generate pressure waves. The stations provide data for the study of coupling across a very broad frequency band between the atmosphere and the solid Earth. We will review the current opportunities that exist for combining seismic and pressure data for studying not only sources of these waves but also for characterizing the atmosphere as a function of time.

Early Career Investigators - Danielle Sumy, Harmony Colella, Andy Frassetto
New faculty members and researchers have commitments spread across research, teaching, service, student advising, family, etc. This SIG meeting will be split into two parts. First, a panel of seasoned members of the community will profile their career paths and be available to answer questions from early career scientists. Second, we will review the current resources available to assist early career development and discuss ideas for their improvement. This SIG will serve as a formal beginning to the IRIS Early Career Investigator (ECI) Program, a community where we can foster collaboration and openly (and freely) discuss ways to overcome common challenges. We encourage all members of the IRIS community to attend and participate in this SIG. Perspectives and mentorship from more senior members of the IRIS community are particularly welcomed.

Solid Earth Science Computational Facility - Jeroen Tromp, Alan Levander, Artie Rodgers, Louise Kellogg
With dramatic increases in the quality and quantity of geophysical data and the availability of sophisticated open-source numerical modeling tools, there is a need for a Solid Earth Science high performance computing facility. As examples, USArray and similarly dense international arrays are providing seismologists with a tsunami of new data. Data analysis is keeping up with data acquisition only for the computationally simplest analysis methods, as even computationally modest analysis is often still labor intensive. Imaging/modeling with this data requires powerful numerical modeling tools, automation of routine analysis tasks, and high-performance computing facilities, without which the power of these arrays as observational platforms for deciphering North American structure may never be realized. Such a facility was envisioned in the first IRIS proposal as long ago as 1984. Hardware structure, machine access and scheduling policies in such a facility would reflect the research, education, and training needs of the solid Earth community – thereby enabling rapid major advances in this vibrant area of research.

Friday

Synergies in Seismology between GeoPRISMS and EarthScope - Susan Schwartz, Maggie Benoit, Cliff Thurber
The GeoPRISMS Program, successor to MARGINS, offers near-term opportunities for interdisciplinary onshore-offshore investigations at three US continental margins: Alaska-Aleutians Subduction Zone, Cascadia Subduction Zone, and Eastern North American, and eventually, also in East Africa and New Zealand. Recent community planning workshops for the three US settings, jointly sponsored by GeoPRISMS and EarthScope, outlined the scientific targets and research priorities for each setting, defining research opportunities in seismology and associated interdisciplinary studies. We will review the community-developed implementation plans for these three primary sites, with emphasis on opportunities for the IRIS community, and entertain open discussions about specific projects and collaborations designed to achieve the scientific objectives of the program.

Citizen Science in Seismology - Elizabeth Cochran and Richard Allen
The general public has been enlisted to help with seismology research and hazards mitigation in a variety of projects, ranging from the well-established such as Did You Feel It, to developing monitoring programs such as the Quake Catcher Network, to novel uses of social media. Some projects ask for volunteers to host sensors, while other go door-to-door with specific requests. This SIG will include presentations from some of the groups that count on public involvement, followed by discussion of lessons learned and strategies to engage the public in future projects.

International Development Seismology - What, Where, and How? - Susan Beck, Jay Pulliam
Scientific engagement in developing parts of the world presents the university community with unique challenges and exciting opportunities to directly impact society in ways that complement their fundamental research activities. In addition, scientists conducting research in developing countries have the opportunity to become true global scholars, sharing the excitement and intellectual resources of the scientific quest with local partners. While these experiences can be quite rewarding, sustaining their impetus often requires creative schemes, particularly to harness the necessary financial resources. Over the past few years, IRIS IDS has begun the exploration of these issues and the most effective ways to address them. We invite all members of the IRIS community, at any career stage to share their experiences, opinions, and recommendations for how to make global social responsibility an integral part of our exciting international seismology.

Data Products - Chad Trabant, Tim Ahern
A discussion of data products that are or could be produced by the IRIS DMC and used by the community to aid in research. IRIS staff will give an overview of existing data products currently produced at the DMC. The DMC's product effort is community driven; this is an opportunity for direct feedback with a focus on future data products. For a list of the currently data produced products including information on future products please visit: http://www.iris.edu/dms/products/

Pre-Workshop Symposia

Where individuals are prepared to make a greater effort to address an important need, a half-day or full-day symposium just before and after the IRIS Workshop can be an opportunity to delve deeply into a particular area. Suggestions for additional symposia that link facility activities with research or education projects are welcome, but those planned at this time are:
