Securing Legacy Seismic Data to Enable Future Discoveries

18-19 September 2019

Albuquerque, New Mexico

New seismological data mining methods are enabling discoveries and cross-disciplinary research across Earth system science. Research is challenged by the relatively short time period of observation for which digital records are readily available. Historical data recorded on paper and other physical media when suitably converted into machine readable formats, extends the time period of Earth observation and research back many decades. For legacy seismic data to be made available to support Earth system science, compelling challenges must be addressed in handling, preserving, and creating and maintaining archives of digital renderings of this "dark" data. 

This workshop seeks to bring together stakeholders across organizations and scientific domains to discuss the science drivers and challenges facing community use of legacy seismic data. We actively encourage participation among users and maintainers of these data collections as well as experts in their usage and potential applications. We welcome contributions as they pertain to NSF 10 Big Ideas including climate change research, machine learning, and big data analytics. This workshop will clearly identify the scientific importance of securing these data as well as provide a clear statement and prioritization of community needs and interests.

Workshop Information


The workshop will begin on Wednesday, September 18 @8AM and end Thursday, September 19 @5PM. 


Registration is now open. [register]

Registration is open until full.

Attendance Limit: 55


Limited travel support is available but extremely limited. Please apply when registering. We are seeking additional funding and will base support on funds available.

See Logistics for hotel and travel information.


under development

The workshop will include lightning talks, posters, and a limited number of contributed talks. Please indicate on the registration form your interests in participating in these activities.

Image Collections

We are interested in learning more about your efforts to rescue analog seismograms and seek information about your collection of imaged records and their associated metadata. If you wish to take part in a survey when ready, please contact Lorraine.

Science Drivers

An important outcome of this workshop is to establish the science drivers for the use of legacy data. We are seeking contributions from the community for the workshop report.  You do not have to attend the workshop to contribute a brief. Contributed science briefs should be 1-2 pages long and clearly state how legacy data was used and its importance to the study's outcome.

Please indicate when registering if you are interested or contact Lorraine: 

A template will be mailed in late August.
