Forum and Data Repository
Comments for the Geology Forum should focus on the broad assertions in the original article or their implications, and they must not be too specific or personal. A Comment should normally be submitted within 10 months of publication of the original article. The Geology editor will send a copy of the Comment to the original author(s) for a Reply, which should be submitted to GSA within one month. Comments and Replies may be subject to external review at the discretion of the science editor. Comments and Replies will continue to be limited to the equivalent of one printed page, including references, figures, and tables (about 7500 characters of text equal one printed page). Comments and Replies are published only online at www.gsapubs.org; the print version will contain a notice in the table of contents indicating the titles, authors, and location of online material.
Authors can submit information that supplements and expands on their published article as Supplementary Material. (Newly acquired data presented only in graphs in the manuscript must be placed there.) This supplemental information should support the main scientific conclusions of the paper; it should not be a necessary part of the understanding of the ideas and conclusions of the published paper. It is generally restricted to data tables and related graphs or figures, and/or explanations of methods (where this is not central to the paper). Supplemental information is not to be used to provide additional space (for text or figures) to convey the message of the article.
Criteria for Supplemental Information files submitted to GSA:
- Central to the main scientific conclusions of the paper.
- Provide supporting documentation only.
- Likely to be usable by other scientists working in the field.
- Described with sufficient clarity to be understandable by other scientists. Figures and tables must have clearly explained captions. References cited solely in the supplementary files should be listed within those files.
- Can be put into one of the required digital formats, within size constraints.
Proper Formatting for Supplementary Files
Whenever possible, submit your files in PDF format. You are encouraged to create your own merged PDF that contains all of your supplemental files (excluding multimedia files). Only one PDF file per article will be posted. The following file types are acceptable, but will be converted to PDF before online posting.
- Text files in MSWord or rich text format (.doc, .docx, .rtf)
- Table files in MSExcel format (.xls, .xlsx)
- Figure files, with suffix .eps, .tif, .gif, or .jpg
Multimedia files will be included as a separate file in our data repository. We will create a separate link for each multimedia file. Multimedia files in .mpg, .avi, .gif, .fla, .mov, or .mp3 are the only supported file types.
Supplemental Information for a GSA article must not exceed 50 MB total size (for all files combined).
Citing GSA Supplemental Information
Supplemental information will be referenced in the text of the manuscript with the file name and a link to the online file. A footnote will appear in the printed version of the journal — for example:
"Supplemental information (Tables DR1-DR2 and Figure DR1) is available online at http://www.geosociety.org/pubs/ft2012.htm."
