Dear DEG Member,

Welcome to the December 2018 issue of DEG's Spheres of Influence, which is now available online or as a downloadable PDF file.

This issue offers important information and relevant articles that you won't want to miss, including:

• DEG President Mary Barrett finds that sustainable development is a prominent topic in the industry-related meetings she has attended. In her article Industry and the Environment: News from Recent Professional Meetings, she summarizes the diverse approaches and discussions that ensued, and she concludes that DEG has a role in continuing to bring this topic forward.
• Kenneth Plato describes the breathtaking beauty of Zabriskie Point of Death Valley, as well as the geologic processes that created “one of the most enigmatic landscapes in the United States.”
• The DEG Invited Speakers and Planned Technical Sessions, ACE 2019 Meeting provides information about two exciting technical sessions - the DEG/EMD luncheon with guest speaker Eirik Wærness and the DEG Special Session with guest speaker Iain Stewart.

Don't miss this issue of the DEG's Spheres of Influence. I look forward to your comments and feedback. If you have a submission for the next issue or have any questions, please feel free to .

Warm regards,

Olga Popova
