AGU will insert running heads and page numbers at the top of the final page. Running heads consist of the short title of the article and the authors’ names. Please supply a short title that is not longer than 40 characters including the spaces between words.
 
 

In-text citations are set in regular type, not bold, and placed within brackets [ ], not parentheses. Use semicolons to separate a string of references (see sample). All information within brackets belongs to the citations.

Black and white line art and photographs are cited in text as figures, and color illustrations are cited as plates. Number figures separately from plates. Examples: “Figure 1,” “Plates 1a and 1b,” "Figures 2a-1d,” “Plate 2.” Indicate a “callout” that identifies the in-text citation of each figure or plate in the margin of the camera copy. Callouts must be in numerical order.
