AB: The IRIS GSN began recording data in 1988 and at that time the IRIS DMC was nearly non-existent. The GSN would eventually generate roughly 500 gigabytes of data per year and we anticipated that hundreds of requests would likely be serviced per year. While these figures seem small by today's standards, in 1988 they were formidable. Currently the IRIS DMC archives more than 16 terabytes of data per year and this year we will service more than 100,000 requests for data. The DMC has evolved in a manner that is closely linked to the demands of the seismological and earth science community. We have developed a diverse set of request tools, data management systems and tools that assist users in getting seismological data in the form they need, and in the time frames required by their research. One of the most significant accomplishments of the DMC over the past ten years has been the integration of seismological data from a vast array of permanent and temporary networks at global, national and regional scales. In the early days of IRIS, the DMC's holdings were very much dominated by GSN data and while to this day the GSN data lie at the heart of the DMC, the holdings have been significantly improved by adding data from other sources. Data from IRIS PASSCAL experiments, international partners in the Federation of Digital Seismographic Broadband Networks (FDSN), USGS national and regional networks, and data from a variety of other networks now routinely flow into the IRIS DMC. These data are seamlessly integrated with data from the GSN making the combined data holdings of far greater scientific value. This talk will provide a summary of the current data holdings, access techniques and usage of the IRIS DMC focusing on the tremendous contributions of the GSN.
