Cascadia Initiative Data
OBS data from the first two years of the Cascadia Initiative is available at the IRIS DMC. Visit the Data Highlights page to find out more about data and metadata

During the 2014 field season there were 5 Cascadia Initiative cruises and two PI-led expeditions that recovered 69 OBSs and deployed a total of 93. All data from Year 4 of the CI will be publically available when it is recovered in 2015.
During the 2013 field season there were 6 Cascadia Initiative cruises. Operational objectives were to recover 70 OBSs deployed in 2012 and deploy 70 OBSs for 2013. Relevant documents can be found on the 2013 CIET Expedition pages
During the 2012 field season there were 6 Cascadia Initiative cruises. Operational objectives were to recover 62 OBSs deployed in 2011 and deploy 70 OBSs for 2012. Cruise objectives and relevant maps/files can be found on the 2012 CIET Expedition pages.
During the 2011 field season the CIET completed 3 oceanographic expeditions to deploy 64 ocean bottom seismometers (OBSs). All 64 OBSs were recovered between May-July 2012. Visit the 2011 Expeditions page for links to individual legs and related information.

CIET and Fisheries Cooperate on successful field season:
The deployment of OBSs in shallow water requires close cooperation with fisheries in the PNW. During the 2011 field season CIET sited dozens of OBSs in shallow water and consulted with local fisheries and stakeholders so as to minimize our impact on their operations (and vice versa!). Scott McMullen from the Oregon Fishermen’s Cable Committee (OFCC) writes:
This is a real success story of the benefit of collaboration. Just so you understand, had the seismometers been deployed in their originally proposed positions, I am sure that the outcome would not have been so positive–for your instruments and for the fishing industry. Locating the seismometers near known “hang-ups” eliminated the impact on the trawl fleet and likely spared the devices some damage. I applaud you for modifying the design to recover the instrument anchors rather than abandoning them, another very positive development.
