GEM 2019 Xiʹan:
International Workshop on Gravity, Electrical & Magnetic Methods and Their Applications

GEM Beijing 2011 and GEM Chengdu 2015 attracted large numbers of abstract submissions and participants from around the world. Since GEM 2015, the last few years have witnessed the exciting development and application of machine learning techniques to geoscience problems in the midst of an extended period of downturns in oil and mining industries. In the face of great challenges and opportunities, GEM 2019 is targeted to be an international forum for geophysicists to communicate the latest developments and exchange ideas in potential fields and electromagnetics. Specifically, the goal of GEM 2019 Xi’an is to bring together geophysics researchers and practitioners from academia, government agencies, resource companies, and contractors to share the latest technological and methodological advancements and their successful applications to practical problem solving, and to inspire discussions among the participants about the best practices of turning electromagnetic, gravity, and magnetics data into value-added information. We also expect this workshop to serve as a platform for geophysicists to reflect on the roles that these methods can play in the era of big data and artificial intelligence.

About Xiʹan

Xiʹan is the oldest of the Four Great Ancient Capitals of China and the starting point of the famed Silk Road. Xiʹan boasts a great wealth of historical and cultural heritages, as well as its world-class tourist attractions such as the Terracotta Army of Emperor Qin Shi Huang and nearby Huashan Mountain for adventurous hiking.

An Evening on Diversity

Opening Our Eyes to Diversity and Equality in Geophysics Around the World

Coordinators: Elizabeth Maag-Capriotti and Aline T. Melo

Have you ever considered what it is like to be a geophysicist on the other side of the world? Have you ever considered the challenges faced by the opposite gender? Join us for an eye-opening experience to explore the state of diversity and gender equality across the globe. The evening will feature a panel of geophysicists from different regions of the world. Each will share their personal experiences and offer advice on questions and challenges presented by the audience. A networking session will follow for further discussion on how to improve the global efforts for equality in geosciences.
