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.

Cascadia Amphibious Array Design

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.

Cascadia Cruises are led by the Cascadia Initiative Epedition Team (CIET), comprised of the following team of scientists:

  • Doug Toomey, Team Leader, University of Oregon
  • Richard Allen, University of California, Berkeley
  • John Collins, Woods Hole Oceanographic Institution
  • Bob Dziak,OSU/NOAA, Newport, OR
  • Emilie Hooft, University of Oregon
