hydrophone (HYDBB) data • An initial period of 6 months of full-resolution HD Video data (.mov files)
In 2014, through a formal NSF-IRIS agreement, the OOI provides data from the broadband and short-period seismometers and low frequency hydrophones at Axial Seamount, Slope Base, and Southern Hydrate Ridge through a different delivery system managed by the Incorporated Research Institutions for Seismology (IRIS) (https:// www.iris.edu) Data Management Center (DMC). IRIS is a consortium of academic and research institutions dedicated to facilitating the study of seismic sources and Earth properties using seismic and other geophysical methods. Among their many data and educational products is a widely used data portal that is the primary source for seismic data in the geophysical community. When a user requests IRIS-served data on the OOI Data Portal, the user is provided a link to an external website operated by IRIS that details all the information needed to query, obtain, make plots, and do basic filtering from the IRIS DMC. A screenshot of the IRIS interface is shown in Figure 3.25.
• An initial period of 10 years of compressed HD Video data (.mp4 files) • All uncabled raw data currently in the system = ~7.3TB, cabled non-A/V raw data currently in the system = ~11.0 TB, and large format A/V data (HYDBB and HD Video) = ~316 TB. Despite this published schedule, no data have yet been removed from the RDS. If data are removed from the RDS for space reasons, they would not be deleted from OOI archive systems, and any data not on the RDS would be made available to users upon request. There are no native search, subsetting (slicing), or conversion tools available directly on the RDS. However, users can apply parsing/processing routines on the data using their own scripts to obtain processed data from the RDS. The RDS is currently the only public-facing repository of data from the cabled high-definition video camera installed at Axial Seamount, and from the cabled broadband hydrophones.
