GGFC Special Bureau for the Core

The Special Bureau for the Core (SBC) is one of the eight Special Bureaus (SBs) of the Global Geophysical Fluids Center (GGFC), established by the International Earth Rotation Service (IERS) on January 1, 1998 to facilitate the link between the space geodetic and the geodynamic communities. Within the GGFC, the SBC is responsible for the research and data service activities related to the core and plays a role in stimulating and coordinating research on this topic. In particular, the SBC focuses on theoretical modeling and observations related to core structure and dynamics (including the geodynamo), and on inner core – outer core – mantle interactions.
