Presidential Address: Our expanding sphere—grand challenges for planet Earth and for SEG

摘要

The mission of SEG is to serve the geophysics profession as the international society of applied geophysics. The vision of the outgoing Executive Committee has been to increase the Society's effectiveness in serving its internationally distributed membership. This vision is shared by the Global Affairs Committee and many others within the Society and is certainly our Zeitgeist—the prevailing spirit of our time.
