Williams, Univ. of Reading Associate Editors Christopher Arridge Enrico Bertuzzo Zanna Chase Lixin Wang Andrew Yau Geophysical Research Letters publishes short, concise research letters that present scientific advances that are likely to have immediate influence on the research of other investigators. GRL contributors can focus on a specific discipline or apply broadly to the geophysical science community. Criteria and Submission Data As GRL is a letters journal, limiting manuscript length expedites the review and publication process. A magazine-sized GRL can reach and be of interest to the largest AGU audience. With this goal, the Editorial Board evaluates manuscripts submitted to GRL according to the following criteria: • Is it a short, concise research letter? • Does it contain important scientific advances? • Would it have immediate impact on the research of others? Submit your manuscript electronically by logging on to: http://grl-submit.agu.org, and by clicking on the appropriate link. For peer review, you may submit text in Microsoft Word, LaTeX, or PDF formats. Artwork should be submitted as encapsulated postscript (.eps), tagged image file format (.tif), .jpg, or .pdf files. See www.agu.org/pubs/authors/ for information about file preparation. GRL editors are specialized by topic. The subject of your paper determines which editor handles the review process. Claims and Changes of Address. Send address changes to the AGU Member Service Center with at least 5 weeks’ advance notice. Claims for missing issues due to insufficient notice of address change or such reasons as “missing from files” cannot be serviced. AGU is growing and diversifying, creating a greater range of disciplines. To maintain the quality and rapid turnaround needed for GRL, we are asking authors to contribute their part. GRL enforces its standards for all electronic files. Specifically, the wrong size fonts or spacing, unintelligible figures or captions, improper references, incorrect digital formats, or other poor copy will not be accepted. Such electronic files must be corrected and may be treated as a resubmitted manuscript with new dates at the discretion of the editors. The editors reserve the right to dismiss a submission without peer review if it does not meet the above stated GRL criteria. The required elements are as follows: Copyright. Permission is granted for individuals to make single copies for personal use in research, study, or teaching; and for use of figures, tables and short quotes from this journal for republication in scientific books and journals. AGU requests that all sources are cited appropriately (there is no charge). (1) Manuscript. An electronic copy of a manuscript must be submitted for review (Find current information on submission and publication on the GRL Web site at: www.agu.org/journals/gl/). Assistant Director of Publications Maxine Aldred Publications Office. For assistance with accepted manuscripts, color charges, file specifications, or AGU publication policy, contact Sr. Production Coordinator Ann Butler (abutler@agu.org), +1 202.777.7322. For help with submissions, contact grlonline@agu.org. The appearance of the code at the foot of the first page of an article in this journal indicates the copyright owner’s consent that copies of the article may be made for personal or internal use of specific clients. This consent is given on the condition that the copier pays the stated fee per copy through the Copyright Clearance Center, Inc., for any copying beyond permission by Section 107 or Section 108 of the U.S. Copyright Law. This consent does not extend to other kinds of copying, such as that for advertising or promotional purposes, creating new collective works, or resale. Articles published prior to 1980 are subject to the same provisions. Reproduction of multiple copies and the use of full articles or extracts, including figures and tables, for commercial purposes requires specific written permission from AGU. (2) Format and Size. GRL has strict length restrictions. Use the calculator at http://www .agu.org/pubs/authors/pub_fees/calculator.shtml. Dynamic graphics that meet standards are in addition to this allowance. (3) Abstract. Each manuscript must have an abstract that clearly describes the paper and is no more than 150 words long. POSTMASTER: Send address changes to Geophysical (4) Index Terms. At least one and up to five numerical index terms must be provided when submitting the article. See http://www.agu.org/pubs/authors/ manuscript_tools/journals/ for current index terms. Geophysical Research Letters (USPS 0150-10; ISSN 0094-8276, print; ISSN 1944-8007, online) is published semimonthly by the American Geophysical Union from 2000 Florida Avenue, N.W., Washington, DC 20009 USA. Periodicals postage paid at Washington, DC USA and at additional mailing offices. (5) Author’s Information. All authors’ addresses, telephone numbers, fax numbers, and e-mail addresses must be included. Research Letters, AGU, 2000 Florida Ave., N.W., Washington, DC 20009 USA. Copyright 2012 by American Geophysical Union. 16 August 2012 (6) Coauthor Assent. With multiple authors, the submitting author must certify that all coauthors know of and concur with the submission of the manuscript. (7) Statement on Prior Publication. GRL needs to be aware of pending or previously published articles that use or have used any of the same results presented in the submitted manuscript. Such information does not generally prejudice review and acceptance, but the submitting author needs to state in writing that “no results/data/ figures in the manuscript have been published/submitted in whole/part elsewhere,” or else identify results/data/figures in this manuscript that have been taken from published/pending papers. (AGU policy states dual publication is unacceptable. No manuscripts can be published without copyright transfer from the author and, further, written permissions from copyright holders of previously published figures/tables are required. It is unethical for an author to publish manuscripts describing essentially the same research in more than one journal of primary publication. Submitting the same manuscript to more than one journal concurrently is unacceptable.) (8) Review Information. A list of five potential reviewers (names, addresses, and e-mail addresses or telephone/fax numbers) and any other information useful to the editor in acquiring a fair and prompt review is required during the electronic submission. Auxiliary Material Authors may include electronic material beyond the limits of the manuscript copy. All auxiliary material will be reviewed with the article, and the paper must stand alone without it. The editors shall determine if it is appropriate. For complete guidelines see http:// www.agu.org/pubs/authors/manuscript_tools/ journals/index.shtml. Production Files The following file formats are required for production: text—Microsoft Word or LaTeX; figures— encapsulated postscript (.eps), tagged image file format (.tif), .jpg, or .pdf files. The editors recommend that at revision these formats be submitted so that if the article is accepted, it may be transferred directly to production. Publication Charges The publication charge income received for GRL helps support rapid publication, allows more articles per volume, and makes possible the low subscription rates. Therefore authors are asked to honor publication fees. There is no charge for color in any format. A complete list of author fees and a calculator, which authors can use to determine the potential charges for their paper, is online at http://www.agu.org/pubs/authors/. Subscriptions AGU members may subscribe to GRL in print or online editions for their personal use. The annual rate of a print subscription is $755 (U.S. members) and $1645 (non-U.S. members). The annual rate for access to the online edition is $141. Student members may subscribe at reduced rates. Contact AGU for special rates for libraries and other multiple-use institutions. Individual issues are offered for sale based on availability; please contact Member Services with such requests.
