Creating Fair Legacy Seismic Data

Session: Back to the Future: Innovative New Research with Legacy Seismic Data [Poster]

Type: Poster

Date: 4/19/2021

Presentation Time: 11:30 AM Pacific

Description: 

Efforts to preserve analog seismic data and make them available digitally are underway at a limited number of institutions world-wide. While these preservation efforts provide leadership in best practices in conservation, imaging, and vectorization, little community discussion has transpired on standards and how the collections can meet FAIR data principles. That these data be Findable, Accessible, Interoperable, and Reusable provides guidance for data management and stewardship in the modern digital ecosystem allowing centers managing these products to develop uniform tools for discovery and return legacy data in formats and accompanied with metadata to ensure its usability. Establishing standards before significant work begins will help to ensure continuity and consistency in data preservation projects, high-quality products, and comprehensive capture of key information.

A focus of 2019 Securing Legacy Seismic Data to Enable Future Discoveries held September 18-19, 2019 in Albuquerque, New Mexico was to understand the preservation lifecycle and research uses towards identifying the core metadata for legacy data preservation and use. Prior to the workshop individuals representing 10 projects worldwide identified 39 metadata elements. These elements were grouped into 6 broad categories that parameterized the data: 1) Time of Data, 2) Station/Channel, 3) Sensor, 4) Recording System, 5) Image File, and 6) Other. Workshop participants were asked to consider each of the elements and identify whether they should be Required, Recommended, Optional, or Omitted. Participants also requested 20 other elements be added. These metadata elements and survey results will be presented. Based on the results of this initial metadata survey and meeting feedback, the next activity will be to incorporate the new and/or modified elements into an updated survey and submit it to the international community for broader consideration and consensus. This will set the stage for FAIR legacy data.

This presentation will update the community on the current state of standards for legacy data.
