USArray Design Workshop
San Diego, CA 
May 3-4, 2001

The USArray Design Workshop was held in San Diego May 3-4, 2001 to discuss array design issues for USArray.  The purpose of this focused workshop was to look at the array geometry and how it will affect the imaging science that will come out of the program. 

The "Bigfoot" component of USArray will consist of 400 broadband stations on a 70 km grid.  These stations will occupy a given site on the ground for approximately 18 months and then move to another location.  To date two possible orientations have been looked at.  One is to have the array configured as a square array 1400 km on a side.  The second is to have the array configured as a more linear array in a North/South orientation across the US.  The question addressed by the workshop was: Do either of these (or some other potential orientation) offer significant advantages for lithospheric and deep Earth studies, including tomography and other types of imaging?

The participants discussed a broad range of issues related to the types of scientific investigtations that would be conducted with the data from the USArray.  A summary of these issues and their impact on USArray operations is given in final report.
