#SEG2015 Wiki Awards

Between now and 4 September 2015, SEG is hosting a competition to recognize outstanding member, student member, and Student Chapter contributions to the SEG Wiki. Add your layer to the science of geophysics, and help us connect the next generation of geoscientists. Together.

Wiki Meetup at 2015 Annual Meeting

Join the SEG Wiki Committee and your peers in New Orleans for the 3rd annual Wiki Meetup. This year, the meetup will blend four informational stations on: 1) SEG Wiki 101 - the basics; 2) contributing to the wiki; 3) using open data; and 4) pioneers of the science & women in geoscience, with one informal 5) hack station (or, unconference). Meetup participants should bring a laptop and an idea for how the wiki can connect and inspire the next generation of geoscientists.

TLE tutorials

The SEG publishes geophysical tutorials bimonthly in the The Leading Edge. The ninth tutorial, Mapping and validating lineaments, was recently published in the August 2015 edition.

AGI's Critical Issues now on the wiki!

SEG has partnered with the American Geosciences Institute to add its Critical Issues Program. The articles provide information on basic geoscience topics to help introduce the subject and provide a great foundation to build more in-depth articles. Start exploring!


Many of the pioneers in the development of exploration geophysics reside in the Biographies. Add your insight and knowledge of these trailblazers for the next generation.

Please help us develop our women in geoscience biographies.


Wiki chat

The next #SEGWikiChat will be Tuesday, 29 September from 10:00-11:00am CDT on Muut. The SEG Wiki team will be joined by SEG Wiki Committee member Azie Aziz to preview the Wiki Meetup at Annual Meeting.

Visit Muut to read our August discussion with our first wiki interns, Judy Smith and Stamatina Mattie Mylonas and check out the first two articles: plate tectonics and greenhouse gases.


About the SEG Wiki

The goal of the SEG Wiki is: to expand the world’s knowledge of applied geophysics, to provide further details of ("layer") the science itself, and to engage emerging professionals in the field. Robert E. Sheriff's Encyclopedic Dictionary of Applied Geophysics, fourth edition and Oz Yilmaz's Seismic Data Analysis seeded the SEG Wiki with its initial content. We encourage you to read, edit, and enhance the SEG Wiki. Add your layer to the science of applied geophysics today.
