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 planetologyvolcanology 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 issue: 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.
