AGU and the Society of Exploration Geophysicists (SEG) complement each other in many ways. SEG is known for strength in applied geophysics and method development, while AGU is known for application of geophysics to broader scientific questions in Earth and atmospheric sciences. These boundaries are of course gray, and there is substantial and complementary overlap of interests, particularly among some disciplines; these include the study of passive and active source seismology, gravity and magnetic anomalies, and electrical and electromagnetic methodologies, as well as interest in the application of these methods to crustal structure, near- surface geophysics, geothermal exploration, and basin analysis. Facilitating communication between members of SEG and those of AGU has a significant impact on the geophysical sciences. The AGU-SEG Collaboration Committee (ASCC) was established as part of the AGUSEG Alliance Agreement, signed in 2010. In the agreement, ASCC was “charged with considering and making recommendations to the respective organizations regarding other areas of cooperation, such as joint workshops or programs and continuing- education courses.” The first committee-wide meeting was held on 11 February 2011. Subsequent meetings are scheduled every 4–6 weeks.
