The Cascadia Initiative community seismic experiment marine deployment occurred offshore Washington and Oregon, with ocean bottom seismometers deployed and recovered from 2011 to 2015. Instruments that were deployed came from the Lamont-Doherty Earth Observatory, the Scripps Institution of Oceanography, and the Woods Hole Oceanographic Institution. Land stations were also deployed during this experiment and data from both off-shore and on-shore stations are archived and available under the _CASCADIA virtual network code at the IRIS DMC.
Data from the LDEO, WHOI, and SIO ocean-bottom instruments deployed in 2014 and recovered in August-October 2015 are archived and publicly available under station code 7D at the IRIS DMC. This data can be accessed using all IRIS DMC request tools. If you have any problems accessing this data or have questions, please contact Kasey Aderhold from the OBSIP OMO office at firstname.lastname@example.org. Data includes (bold indicates newly added):
Please note that the Cascadia Initiative Channel Naming Conventions have been updated to reflect the different sampling rates of the two SIO instrument types.
More information about the Cascadia Initiative is available here on the OBSIP website. A Cascadia Horizontal Orientation Report for the Year 4 deployment will be generated and published to this website in April.
