When I attended my first AGU meeting as a graduate student 13 or 14 years ago, I eagerly dashed from sessions in my own small corner of atmospheric sciences to sessions in planetology, volcanology, and other geophysical subjects. In that same spirit of curiosity, one of the things I most appreciate about my AGU membership is the opportunity to learn about work in other fields by reading Eos every week. Almost every issue, however, displays a startling disparity in skill with which Eos authors make their subjects accessible to readers outside their own disciplines. Here's an example from the 28 September 2004 issuec One article, on Indonesian throughflow, clearly explains in the first paragraph why it is important and how little is known. The article reads well for a nonspecialist.
