Objective: High quality images of the mantle structure beneath spreading centers can only be achieved through international collaboration, because large-scale seismic and electromagnetic experiments in the same area are required. The proposed Working Group has two main roles, 1) promoting experiments to image the mantle structure at one or two ridge systems, and 2) encouraging scientists to link effectively for interpreting and using the high quality images. The key scientific questions to be addressed by imaging the mantle beneath spreading centers are 1) clarifying mantle dynamics associated with different ridge systems, and 2) identifying the parameters controlling various lithospheric features at different types of ridge systems.

OBS and OBEM Project Listings
The InterRidge Mantle Imaging Working Group would like to promote large-scale seismic/EM experiments to image the mantle structure at ridge systems. We encourage PIs with cruises for these experiments to consider availability of bunks for graduate students (esp. students from a different country) and/or to enable international collaborators to deploy additional instruments on the cruises.
