Gravity & Magnetics User Group

If you are interested in joining internet discussions with practicing gravity & magnetics specialists from all over the world, including professionals from universities, research institutions and natural resource exploration companies, then you can join the Gravity & Magnetics User Group. The group is supported by Lamont-Doherty Earth Observatory at Columbia University.

Of course there is no requirement to participate in discussions, but the group is a valuable forum for passing information and finding out the latest news with gravity & magnetics. As a past Chair of the Society of Exploration Geophysicists (SEG) Gravity and Magnetics Committee, I found it extermely useful for communication with other committee members.
