IRIS has been working with the Ocean Leadership Consortium (OL) to make data from the cabled array component of the OOI project deployed off the coast of Washington and Oregon available to the scientific community. We are happy to announce that the data are now openly available through the IRIS DMC. The seismic network code for these data is OO.

IRIS wishes to thank the OL team led by Mike Kelly as well as John Delaney’s group at the University of Washington that made this all possible.
Thanks especially to Deb Kelley, Brian Ittig, Dana Manalag, and Chuck McGuire at the University of Washington for their efforts on the OOI side of the collaboration.

IRIS provides a metadata aggregator the allows users to see details about the data, types of seismometers, locations, etc.
The following map shows the locations of the various 13 stations and is also available online.

These data can be accessed through all tools at the DMC that our community is used to using including:

• web services
• real time feeds
• email-based tools such as BREQ_FAST
• web-based tools such as Wilber3

The timeseries tool at the web services URL allows users to select specific instruments and parameter ranges and generate a plot. The following link is to a plot of an event recorded by one of the OOI stations on Axial Seamount during a 1 minute interval on December 12, 2014, from the mid-period channel, high pass filtered at 10 Hz, and converted to units of ground motion (meters per second).

These data are generated as part of a project funded by the NSF through an MREFC grant that funds the Ocean Observatories Initiative. IRIS efforts are supported by the NSF funding of the SAGE proposal to IRIS provided by the GEO Directorate of NSF.
