Geophysical Journal International

Author Guidelines

Scope
Geophysical Journal International is one of the world's leading primary research journals in geophysics. The Board of Editors is international in representation.

Geophysical Journal International publishes top quality research papers, letters and book reviews on all aspects of theoretical, computational, applied and observational geophysics. It welcomes submissions at any time from scientists world-wide via http://mc.manuscriptcentral.com/gji/. A guide to submission is available. You should prepare your manuscript as a single file including all figures and tables, in PDF, Word, RTF or plain text format. GJI aims to publish all papers in a timely fashion. Authors who submit a paper are expected to be able to certify that the paper is original work, has not been published before and is not being considered for publication elsewhere.

Author Services
Online production tracking is now available for your article through Wiley-Blackwell’s Author Services.

Author Services enables authors to track their article – once it has been accepted – through the production process to publication online and in print. Authors can check the status of their articles online and choose to receive automated e-mails at key stages of production. The author will receive an e-mail with a unique link that enables them to register and have their article automatically added to the system. Please ensure that a complete e-mail address is provided when submitting the manuscript. Visit http://authorservices.wiley.com/bauthor/ for more details on online production tracking and for a wealth of resources including FAQs and tips on article preparation, submission and more.

OnlineOpen
OnlineOpen is available to authors of primary research articles who wish to make their article available to non-subscribers on publication, or whose funding agency requires grantees to archive the final version of their article. With OnlineOpen the author, the author's funding agency, or the author's institution pays a fee to ensure that the article is made available to non-subscribers upon publication via Wiley Online Library, as well as deposited in the funding agency's preferred archive. For the full list of terms and conditions, see http://wileyonlinelibrary.com/onlineopen#OnlineOpen_Terms.

Any authors wishing to send their paper OnlineOpen will be required to complete the payment form available from our website at: https://authorservices.wiley.com/bauthor/onlineopen_order.asp (Please note this form is for use with Online material ONLY.)

Prior to acceptance there is no requirement to inform an Editorial Office that you intend to publish your paper OnlineOpen if you do not wish to. All OnlineOpen articles are treated in the same way as any other article. They go through the journal's standard peer-review process and will be accepted or rejected based on their own merit.

Exclusive Licence Form
All papers must be accompanied by a signed Exclusive Licence Form (ELF) upon acceptance for publication. There is no fee to publish in Geophysical Journal International. Signature of the ELF is a condition of publication and papers will not be passed to the publisher for production unless a signed form has been received. Please note that signature of the Exclusive Licence Form does not affect ownership of copyright in the material. (Government employees need to complete the Author Warranty sections, although copyright in such cases does not need to be assigned). After submission authors will retain the right to publish their paper in various medium/circumstances (please see the form for further details). To assist authors an appropriate form will be supplied by the editorial office. Alternatively, authors may like to download a copy of the ELF.

PREPARATION OF MANUSCRIPTS
Manuscripts should be in the English language. Spelling, grammar and syntax should follow normal English practice and the Oxford English Dictionary. Please indicate which section of the journal you wish the paper to be published in.

Submit your paper online via http://mc.manuscriptcentral.com/gji/. A guide to submission is available.

Manuscripts should be prepared using LaTeX (Geophysical Journal International class and style files are available as a single Zip file) or in RTF or Word format. Footnotes are strongly discouraged. Except where common practice in geophysics dictates otherwise, units should follow the Système Internationale (SI). Pages must be numbered sequentially.

The manuscript should be arranged as follows:

• Title page, containing authors names, affiliations and e-mail addresses
• Summary and keywords
• Main body of the paper
• Reference list
• Figure legends*
• Tables*
• Figures*
• Appendices*

• Sections marked (*) are discretionary. All others are essential. The form of each section is described below.
  

  Title page: In the format:
  • The full title of the paper as it will appear in the journal
  • Authors' names
  • Authors' affiliations, linked to the list of names, if appropriate, by superscript numbers
  • The following proforma, for use by the receiving Geophysical Journal International office:
  Accepted date. Received date; in original form date
  • An abbreviated title suitable for page headings
  • Name and contact details of the corresponding author including phone/fax/e-mail.
  Summary: All papers must be accompanied by a summary of no more than 500 words and by an abbreviated title suitable for page headings. The summary should be a single paragraph that states the nature of the investigation and summarizes the conclusions drawn: all papers must begin with a summary. References must not be cited in the Summary. Abbreviations should be avoided.

  Keywords: Authors should provide a list of up to six key words, representative of the content of their paper. The keywords will be printed at the end of the summary and used for indexing purposes.

  Keywords are used to construct the Journals topical index, published before every index, and are increasingly exploited by electronic indexing services. The list of keywords is therefore important in ensuring that your paper reaches its target audience. [The list of key words]

  Main Body of Paper: Text should be laid out across the width of the page in a single column. Leave wide margins and double-space the text to allow room for reviewers to make annotations. Units should always be according to the Système Internationale (SI) unless common practice in geophysics dictates otherwise. Abbreviations of names or concepts should be defined at first occurrence. Indicate in the margin the location of figures and tables. Sections and subsections should be clearly headed, but the numbering of sections is optional. Leave extra space between the end of a section and the heading of the following section.

  Equations should be numbered sequentially with Arabic numerals. All equations should be numbered regardless of whether or not they are referred to in the text. Punctuate equations as part of the sentence to which they relate. Special typefaces (e.g. Greek), and the placing of subscripts and superscripts should be indicated clearly. Text is normally printed down two columns per page; papers with long equations will be printed across the whole page at the production editors discretion or at the request of the author. Note that the journal style for vectors is Bold Roman Times; matrices should be Bold Roman Univers; tensors should be Bold Italic Times and variables and scalars should be italicized. Modifiers are set in Roman type.

  Reference List: References should be listed in alphabetical order at the end of the paper. The abbreviations for the names of periodicals used in Geophysical Journal International are those given in the World List of Scientific Periodicals, 4th edition. If this is not available, examine the reference lists of papers in any recent issue to find the abbreviations, otherwise, give the title of the journal in full, and the Geophysical Journal International copy editor will substitute the correct abbreviation on acceptance. References should be cited in the text by giving the authors name with the year of publication in parentheses. When referring to a work by three or more authors use only the first name followed by et al. even on first use, for example, 'Adams et al. (1997)'. Where several papers by the same first author and from the same year are cited and the citations would otherwise take the same form, put the letters a, b, c, etc. after the year of publication to distinguish them, for example, '(Adams et al. 1997a; Adams et al. 1997b)'.

  Examples:
  In text: Smith & Jones (1990); (Smith & Jones 1990); (Smith, private communication, 1990); (Smith et al. 1990) Three authors, listing only the first author even on first mention.
  In reference list:
  Author, A.B., Author, C.D. & Author, E.F., 1990. Full article title, J. Title Abbrev., 000, 000--000.
  Author, A.B., Author, C.D. & Author, E.F., 1990. Book Title, 2nd edn, Vol. 2, pp. 000--000, Publisher, Place.
  Author, A.B., Author, C.D. & Author, E.F., 1990. Chapter title, in Book Title, pp. 000--000, ed. Author, G.H., Publisher, Place.
  Author, A.B., 1990. Thesis title, PhD thesis, University, Place.

  Authors preparing their papers using the GJI class file may wish to use the [extra] option, which allows the use of \cite{} commands and is compatible with natbib.sty.

  Figure Legends: Figure captions should summarize the figure and explain any annotations used. They should be produced on a separate sheet; they should not run on from the main body of text.

  Tables: Tables must be un-ruled, be numbered serially with Arabic numerals and have captions. They should be typed on separate sheets and their positions in the text should be indicated on the copy. Each table must be cited in the text. Headings should be brief. Units should be placed at the head of each column. Note that, in rare circumstance tables may contain images and be treated as artwork. However, we prefer them to be rows and columns of Refer to Tables in the text as, 'in Table 1' or '(Table 1)'

  Artwork: We want figures to be submitted electronically. Refer to figures in text as '...Fig. 1(a)' or '...Figs 2 and 3' or '... (Fig. 1a); (Figs 1a and b)'. [NOTE: if referring to figures in another paper, a lower-case `f' must be used: `fig. 1(a)', `figs 2 and 3' etc.] Authors are strongly encouraged to submit computer-generated figures in digital form. Note that the process of scanning material such as typical laser printer output can reduce the quality of the printed figure, sometimes very substantially, and this step should be avoided. The publishers can accept figures in TIFF, EPS or PDF format, and where possible, these should be produced directly from the originating programs. Bitmapped elements should be produced at an effective resolution (i.e. at final printing) of 300 dpi or greater. Artwork guidelines are available here.

  Colour Figures : Colour illustrations are welcome, but should only be used when details cannot be adequately observed on black and white photographs. Note that many readers may only have access to grey-scale printers and so authors should be considerate of these readers when preparing their colour images. Also note that the journal is printed in CMYK, which does not reproduce some particularly bright colours possible in RGB mode.

  We are please to announce that a simplified system of charging is now in place. A standard fee of £200 (plus VAT if applicable) is now levied for any paper that uses colour figures, regardless of the number of figures involved. The form is available here. Once completed, please return the form to the Production Editor at the following address:

  Colour work forms must be supplied by mail. We cannot accept colour work forms sent by fax or via e-mail. Any article received by Wiley-Blackwell with colour work will not be printed in colour if the author fails to make their wishes clear before the paper is ready to be published.

  *To read PDF files, you must have Acrobat Reader installed on your computer. If you do not have this program, this is available as a free download from the following web address: http://www.adobe.com/products/acrobat/readstep2.html

  Appendices: A title is required for each appendix. Appendices should appear after the references and should be named A, B, C, etc. Equations in an appendix should be numbered (A1), (A2), etc. If Appendices are greater than 25 journal pages the journal may choose to publish the material via electronic means only.

  Additional Notes

  Express Letters : Express Letters are expedited through the system and should address controversial topics, or present new data on a topic of broad interest. On submission authors should provide arguments why their manuscript is suitable for an Express Letter. There is a strict 5 page limit. As an approximate guide, papers should be no more than 5000 words including figures; each figure will be judged to occupy the space of 300 words. Authors should provide a word count. Papers should be accompanied by a list of up to four potential referees who may be used at the discretion of the Editor.

  Charges: There are no page charges for publication.
  Reprints may be obtained at prices quoted on the order form which accompanies proofs, provided that the order is placed with the publishers when the proofs are returned.
  Colour figures can often convey an authors' message powerfully and concisely, and recent developments in printing technology have significantly reduced the cost of producing pages in colour. The cost of publishing colour work is £200 (plus VAT if applicable). The colour work form is here.
  Authors will be charged for excessive alterations made in proof.
  Unusual costs incurred by the journal (e.g. in preparing inappropriately drafted figures for press) may be recovered from authors.

  LaTeX Class File and Documentation: The distribution (gji-latex.zip) contains a LaTeX2e documentclass file (gji.cls), and an associated guide (gjilguid2e). It also includes extra style files and packages including a preliminary version of a BibTeX style file (gji.bst) which will reproduce the order and configuration of GJI references for use with the [extra] option to gji.cls (compatible with natbib.sty and encouraging the use of \cite{} commands). The zip file also contains the LaTeX2.0.9 style files and support files.

  Electronic Submission of Manuscripts : The Editorial Office welcomes submissions at any time from scientists world-wide via http://mc.manuscriptcentral.com/gji/. A guide to submission is available. Contact the Editorial Staff if you need advice.

  Electronic Submission of Final Copy : Authors should upload their source files in a single .tar or .zip archive to ScholarOne Manuscripts (formerly known as Manuscript Central) as a supplementary file. Once the article is accepted this archive will be sent to the publisher. As mentioned above authors are strongly encouraged to submit computer-generated figures in digital form at high quality, guidelines are available here.

  In the event that a .tar or .zip file is not uploaded then files may be transmitted by ftp to the publisher after acceptance. Very large files should be compressed.

  FTP site: The Wiley-Blackwell FTP site details are as follows. Do not send FTP submissions to this site.
  Host: ftp.edn.blackwellpublishing.com
  User: gji
  Password: magma
  Create a directory, e.g. 'gb000' and deposit all the relevant files in it, along with a readme file detailing the files if necessary.

  It is not possible to accept manuscripts by electronic mail.

  Proofs: Authors will be sent an e-mail notification that the PDF proof is ready. The PDF can be downloaded in high and low resolution from a website specified in the e-mail. It is therefore essential that an e-mail address for the corresponding author is included on the manuscript title page. Proofs will be accompanied by a query sheet regarding ambiguities, unclear sections of text, missing information etc.

  Proofs should be read carefully, particularly equations and other numerical matter. It is the responsibility of each author to check his or her proofs, reply to any queries, and notify the production team of any typographical errors. When updating the reference list, please be careful to update textual citations as well if the year has changed. Proofs should be returned by the date requested if at all possible - delay in returning the proofs will lead to delay in publication of the paper. Authors should keep their own alterations to a minimum - it may be necessary to charge authors for excessive alterations for which they are responsible. If it is suspected that extensive proof changes may alter the science in any significant way, the paper will be put on hold and referred back to the RAS for approval.

  Offprints: A PDF offprint of the online published article will be provided free of charge to the corresponding author, and may be distributed subject to the Publisher’s terms and conditions. Paper offprints of the printed published article may be purchased if ordered via the method stipulated on the instructions that will accompany the proofs. Note that it is not uncommon for printed offprints to take up to eight weeks to arrive after publication of the journal.

  Author material archive policy: Please note that unless specifically requested, Wiley-Blackwell will dispose of all hardcopy or electronic material submitted two months after publication. If you require the return of any material submitted, please inform the RAS editorial office or production editor as soon as possible.

  Further Advice: The editors will be glad to advise authors on any special points of difficulty. See the contact addresses above and on the Editors page.
