Robert Woodward and Katrin Hafner, Incorporated Research Institutions for Seismology (IRIS)
O5.2-674
Global Seismographic Network
An NSF – USGS partnership
30+ years of continuous data
The EarthScope Program: USArray
10+ years of continuous data
Open networks providing long, continuous, and consistent observations
can serve operational mission, fuel discovery, and build capacity
O5.2-674
Comprehensive Metadata
To maximize use and value of the data requires consistent, well-documented configurations
O5.2-674
Openly Shared Quality Results
Shared quality control results help promote best practices
O5.2-674
Very broad band sensors in
postholes, boreholes, and vaults
Higher frequency
Strong motion
Meteorological
Infrasound
Suites of Sensors
Multiple co-located sensors opens new observational possibilities
O5.2-674
Soils
Expected and Unexpected Science
GSN data used
to study the
lower mantle
GSN data used
to study ocean
temperatures
Open,
continuous data
enable a wide
range of
observations of
transient,
seasonal, and
other events.
O5.2-674
Worldwide capability is enhanced by more people, in more countries, using more data
. . . with data from different networks and different purposes
The data are used worldwide . . .
Open Data are a World Resource
O5.2-674
Open networks build technical capacity in multiple ways:
•
Access to data
•
Access to designs and standards
•
Access to QC techniques and tools
•
Drive vendor developments
•
Supporting operational missions and driving discovery

:
•
Improve every network’s ability to meet its mission / operational objectives
•
Enhances research and discovery which, in turn, enhances the mission and
operations
•
Builds a broader base of scientific capability to address societal needs such
as nuclear monitoring, natural hazards, energy sector, . . .
Open networks lead to identification of best practices, which in turn allows all
networks to increase their value and performance
Summary
Geophysicists Woodward and Hafner highlight the transformative power of open data from distributed geophysical networks, emphasizing its role in advancing scientific research, enhancing operational capabilities, and contributing to the mission of ending nuclear explosions. They underscore the value of continuous, well-documented data configurations, openly shared quality results, and suites of sensors for comprehensive observations. The presentation emphasizes the importance of maximizing the use and value of data to drive both expected and unexpected scientific discoveries, showcasing the significant impact of long-term global seismic data accessibility.
