The AESE is the Association of Earth Science editors, an organization with members in various countries – mostly based in the US and Canada. I was recently able to attend their annual meeting, which was held in Calgary, Alberta. It was a wonderful opportunity to get to know other editors who do what I do! There were about 40 people at the three-day meeting, which made it easier to get to know people than a larger conference.
I would recommend joining to any up-and-coming editor of the earth sciences.
