CASCADIA DATA RESTRICTION AND REUPLOAD INFORMATION
The Cascadia Initiative is a community seismic experiment. Cascadia Cruises are led by the Cascadia Initiative Epedition Team (CIET), comprised of the following team of scientists:
The Cascadia Intitiative is an onshore/offshore seismic and geodetic experiment deployed in the Pacific Northwest to study questions ranging from megathrust earthquakes to volcanic arc structure to the formation, deformation and hydration of the Juan De Fuca and Gorda plates.
As part of the 2009 Stimulus or ARRA (American Recovery and Reinvestment Act) spending, NSF’s Ocean Sciences (OCE) division funded the construction of an amphibious array of 60 Ocean Bottom Seismometers by the three IIC’s for OBSIP.
Twenty of the Lamont OBSs will be installed in trawl-resis- tant enclosures and will be available for deployments in water depths extending from the shelf down to 1,000 m. These 20 OBSs will be deployed via the ship’s wire and recovered using a Remotely-Operated Vehicle.
The OBSs will be utilized in four one-year deployments. These experiments will provide an offshore extension of the Earth- Scope Transportable Array (~70 km spacing) as well as 3 dense experiments focused on either imaging various properties of the thrust interface and forearc or recording local seismicity.

During 2014, OBSIP supported the following Cascadia cruises:
During 2013, OBSIP supported the following Cascadia cruises:
During 2012, OBSIP supported the following Cascadia cruises:
Data from the ocean bottom seismometers will be archived at the IRIS DMC under temporary network code 7D (four years of OBSIP deployments) and 7A (first deployment of WHOI-Keck). Temporary and permanent broadband land stations are archived under the network codes 5E (PASSCAL 2014-2015), BK (Berkeley Digital Seismograph Network), IU (Global Seismograph Network), TA (EarthScope Transportable Array), UO (University of Oregon Regional Network), US (US National Seismic Network), and UW (Pacific Northwest Regional Seismic Network). All stations will be available using the virtual network _CASCADIA.
The OBSIP Management Office has generated horizontal orientations for all four years of Cascadia OBS deployments. All reports and appendices are now archived at the IRIS DMC metadata folder for this experiment: http://ds.iris.edu/data/reports/7D_2011_2017/
