GSA Bulletin

Tables

Tables should replace text, not duplicate it. The numbering scheme should reflect each table's physical location in the document—tables in main text start with "TABLE 1."; tables in appendix start with "TABLE A1." See our sample table for further instructions.

GENERAL

SYMBOLS

If several items in a table require footnotes, use relative position in the table to determine the order in which footnotes are marked. Use the following sequence for footnotes: *(asterisk), †(dagger), §(sections mark), #(pound symbol), **, ††, §§, ##, ***, †††, §§§, ###, and so on. If asterisks already appear in the table (such as *Ar for radiogenic argon), do not use them in footnotes; start footnotes with a single dagger (†)

Figures

All illustrations, whether line drawings or photographs, are considered figures. GSA prefers electronic files, but sometimes we may have to scan clean hard copy if the files are unusable. To ensure the best possible results, please prepare art for illustrations according to the following guidelines.

 Electronic Figures

Online Submission and Revision

Electronic figure/photo files should be uploaded in TIFF, GIF, JPEG, EPS, Postscript, Pict, PDF, Powerpoint, or Excel  format and should be clearly labeled with author name, figure number, and file extension, outside of the image area. We do NOT accept MSWord or LaTeX format for figure files.

Accepted Publication-Quality Figures

When your manuscript has been accepted, you will be asked to provide publication-quality graphics. We require two electronic files for each figure: one in the program in which it was created (native format), and one in EPS, TIF, or PDF format. We will also ask for scannable hard copies to be mailed with the electronic files. Generally, halftones should not be scanned at higher than 600 dpi (dots per inch); line art is usually good at 1200 dpi.

The following native graphics formats work best, as long as the version of the application is noted and the file is labeled with the correct extension:

If you create either TIF or EPS files, they must be between 300 and 600 dpi resolution at the desired print size. Label figure files with author name, figure number, and extension. Make sure that the hard copy of the figure that you send matches the electronic file of the figure. Files created in any application other than those listed above should be saved as a .tif or .eps. We do NOT accept low-resolution 72 dpi images (no web images).

Best Resolution

For all figure files, line art should be saved at 1200 dpi at 100% size. Photos alone should be saved at 300 dpi (or higher). Color images should be saved at 350 dpi (or higher) at 100% size.

Placed/Imported images

All images that have been placed or imported into your figure file must accompany this file on disk (i.e., if you import/place a photograph into Illustrator, called photo.tif, you MUST supply this photo.tif electronic file along with your Illustrator file).

Digital Camera images

Files created by digital cameras are preferred as TIFF or RAW format (though .jpeg is acceptable) and must be at least 300-600 ppi when scaled to the desired print size (be sure that your camera is set for highest resolution for best results). We do not accept 72 dpi photo images.

Invisible Elements

Many graphics files contain unnecessary "invisible" elements. These are sometimes imported graphics that the creator of the file has traced over and then set not to print. To save on printer time and to cut down on file size, it is best to delete the unnecessary element rather than just set it not to print.

Color

Please submit your figures in black and white unless you are willing to be responsible for the cost of publishing in color, should your manuscript be accepted. The cost for color is approximately $800 per figure. If your manuscript is accepted, you will be supplied with an exact cost quote. If you are willing to support this cost, please indicate this clearly in your cover letter or in the Manuscript Comment section. Color figures should be built in or converted to CMYK color mode.

 Loose Inserts/Supplements

Loose inserts/supplements (maps, seismic reflections, cross sections, etc.) may be included, and may be printed on one or both sides. Authors must provide both electronic file and hardcopy, sized to the exact publication size, and authors must pay all costs for inserts. These costs include press preparation, printing, folding, handling, and inserting. For questions on loose inserts, contact .
