Welcome to the home page for the PIRE-AfricaArray project. This project is sponsored by the Partnerships for International Research and Education (PIRE) program within the Office of International Science and Engineering at the National Science Foundation (NSF). PIRE funding has been provided to enable participation by U.S. scientists in AfricaArray, a public-private partnership supporting capacity building for Africa's natural resource sector.
The PIRE-AfricaArray project addresses a first-order Earth Science question that cannot be answered without strong intellectual collaboration and partnerships between scientists in the U.S. and Africa and their respective institutions: "What is the structure and origin of the African Superplume?" The African Superplume is a large region of low seismic wave speeds in the lower mantle under Africa that has long been recognized as one of the most prominent upwellings in the mantle, and that possibly holds the key to unraveling the dynamics of mantle convection.
