It endeavors to publish papers of broad interest in the Earth sciences. Contributions that report on observational, experimental, and theoretical investigations pertinent to the understanding of that system are welcomed.     G3 publishes original scientific contributions pertaining to understanding the Earth as a system, including relevant observational, experimental, and theoretical investigations of the solid Earth, hydrosphere, atmosphere, and biosphere. Areas of interest for this interdisciplinary, peer-reviewed electronic journal include, but are not limited to: the physics and chemistry of the Earth, including its structure, composition, physical properties, and dynamics; the physical properties, composition, and temporal evolution of the Earth's major reservoirs and the coupling between them; the dynamics of geochemical and biogeochemical cycles of global scale; physical and cosmochemical constraints on the composition, origin, and evolution of the Earth and its neighbors; the chemistry and physics of solar system materials that are relevant to the formation, evolution, and current state of the Earth and the planets; advances in modeling, observation, and experimentation that are of widespread interest in the earth sciences. Instructions to Authors Scope Original scientific contributions pertaining to an understanding of the Earth as a system, including relevant observational, experimental, and theoretical investigations of the solid Earth, hydrosphere, atmosphere, and biosphere will be considered for publication in Geochemistry, Geophysics, Geosystems (G3). For further information, see About G3. Manuscripts submitted for publication should convey the author's findings precisely and immediately to the reader. Authors are urged to have their manuscripts reviewed critically by colleagues for scientific accuracy and clarity of presentation. If a manuscript has more than one author, coauthors must consent to the final version of the manuscript and to its submission to the journal for publication. Electronic Publication Papers are published by G3 in both PDF and HTML versions. The HTML version, which may include ancillary information such as animations, movies, virtual reality images, downloadable table of data, computer code, etc. that take advantage of the electronic medium (this ancillary information will be considered to form appendices to the paper), can be viewed using a standard World Wide Web browser. The PDF version may also be viewed through a web browser using the Adobe Acrobat pdf plug-in, but may also be printed in color or black and white, producing a document comparable in quality to those published in paper journals. The PDF version may contain hyperlinks to a variety of ancillary information. While authors are encouraged to take maximum advantage of the capabilities of the electronic medium, any manuscript that deals with the subject areas of the journal will be considered for publication. Publication Categories G3 publishes several categories of papers, some of which are nontraditional. Though all papers published in G3 must meet high standards, the criteria for acceptance of each class of paper differs. Reviewers should review each paper in light of the following criteria: Articles contain previously unpublished research results that are of interest to the broader research community. The quality of G3 articles should be comparable to those published in Journal of Geophysical Research, Earth and Planetary Science Letters, and Geochemica et Cosmochimica Acta. Articles should not exceed 10,000 words of text (plus figures, tables, and references). Research Letters are short papers communicating particularly significant findings that justify rapid publication. The quality and impact of G3 letters should be comparable to those published Geophysical Research Letters, Nature, and Science. Letters normally will be limited to 3200 words (plus figures, tables and references). Reviews are papers that are timely and appropriate in the context of recent developments in the fields covered by the journal. Quality and impact should be comparable to papers published in Reviews of Geophysics. Reviews should normally not exceed 25,000 words (plus figures, tables, and references). Authors are encouraged to discuss their plans for Review Articles with one of the editors preparation of a manuscript. Briefs are new categories of publication that convey important scientific information, such as previously unpublished data or techniques that do not require or warrant extensive discussion. Briefs should not exceed a maximum of 3200 words (plus figures, tables, and references).There are three categories of briefs: Technical Briefs report of new experimental or analytical methods and other technical advances, including algorithms and computer programs. Characterizations report models of the chemical and physical properties of Earth's components and reservoirs, and the relationships and fluxes between them, or revisions to previously published models, accompanied by the minimum necessary documentation. Data Briefs report previously unpublished data, with appropriate documentation, accompanied by a minimum of interpretation and discussion. Editorial and Commentary: G3 invites critical comments on any paper published in the journal. Authors will be given an opportunity to reply to these comments. Both comments and replies should be brief and to the point and should not normally exceed 1500 words. G3 also publishes occasional editorials and short communications reporting or commenting on news of interest to the Earth science community. Authors interested in writing a news-related report or commentary should discuss their plans with one of the editors. All of the above categories may include appendices consisting of animations, movies, virtual reality images, downloadable table of data, computer code, etc. Length Guidelines: G3 has established guidelines on the length of the text not because of any limitation in the publication process, but because we believe that science is better conveyed when the writing is succinct rather than verbose. We therefore encourage brevity: papers should be as long as necessary, and no longer. There are no limits on the number of figures, tables, or appendices; however, all such material should serve a clear purpose in conveying the science to the reader. Manuscript Submission and Formats To enhance the speed and efficiency of the publication process, G3 uses an electronic manuscript submission and review system. Submitted papers are first assigned to one of three editors, who will assign it to an associate editor to oversee the peer review process. Manuscripts will be made available to editors and reviewers in pdf format. Reviewers will be encouraged to annotate the manuscript electronically using the Notes feature of Adobe Acrobat Exchange??. The annotated manuscripts will be forwarded to authors along with the editor's decision. Manuscripts for G3 are submitted electronically through "Geophysical Electronic Manuscript System" (GEMS). To submit a manuscript, authors complete a brief submittal form, which replaces the standard cover letter, and then upload their files. Strict adherence to submission instructions is necessary to ensure that the files are successfully transmitted. The following formats are accepted: For Text and Tables: PDF (Portable Document Format/Adobe Acrobat Format version 3.0), which may include figures. Preferred for initial submission, but the final accepted version must be in one of the below formats. LaTex (Use jgrga for stylefile type.) Word Perfect Microsoft Word RTF For figures and graphics: For Vector Art (Line Drawing, graphs, etc.) EPS (preferred) Illustrator (version 5.5 or higher) Canvas (version 5 or higher) PDF For bitmaps and raster images (e.g., photographs, images) TIFF JPEG PDF Ancillary Information Animated GIFs Movies in MPEG2, Quicktime, or Real format. Computer code as text. Java applets that can be executed via a browser may be included, but the code must also form a text appendix. Virtual Reality images Mathematica?? Notebooks MatLab Notebooks Excel Worksheets Downloadable data tables as tab-delimited text. All data published in G3 must be adequately documented (see guidelines). Other formats that can be accessed and viewed (or heard) over the WWW will be considered. Please contact one of the editors before submitting information in one of these formats. Authors are strongly encouraged to initially submit both text and graphics as a single pdf file. This speeds transmission of manuscripts to editors and reviewers. Style Text. The text should be formated for US Letter (8 1/2 by 11 inches) or A4 paper with at least 1-inch (2.5 cm) margins at top, bottom, and sides. Times or Times New Roman is the preferred font. Authors are expected to use correct spelling, punctuation, grammar, and syntax. Spelling and hyphenation of compound words follow the unabridged Webster's Third New International Dictionary and Merriam-Webster's Collegiate Dictionary, 10th edition. SI units should be used throughout. Following recommended style and usage expedites processing and reduces the chance of error in the typesetting. Text footnotes should not be used. The manuscript should be arranged as follows: title page including authors' names and affiliations abstract text reference list tables figure legends figures In the version submitted for review, figures and tables may be integrated into the text, with captions appearing directly below. In the final version submitted for typesetting, figures, figure captions, and tables must be submitted as separate files. Abstract. The abstract should state the nature of the investigation and summarize its important conclusions in a single paragraph. Listing the contents in terms such as "this paper describes" or "the paper presents" should be avoided. Use of the passive voice often indicates that the author is merely describing the procedure rather than presenting conclusions. References should not be cited in the abstract. Abstracts of Articles and Reviews should not to exceed 350 words; those of Letters and Briefs should not exceed 250 words. When a paper is accepted for publication, the abstract will be immediately published on the G3 Forthcoming Papers Web Page and should therefore be suitable for separate publication in an abstract journal and be adequate for indexing. Mathematics. To the degree possible, mathematical expressions should use characters available in the Times and Symbol fonts only. Use of other fonts requires special arrangements be made with the copy editor. Add one extra line space above and below all displayed equations and reactions. Alignment of symbols must be unambiguous. Superscripts and subscripts should clearly be in superior or inferior position and in reduced font size. Fraction bars should extend under the entire numerator. Care should be taken in selecting accents over characters to be certain that they will be viewable on the screen and in downloaded versions of the article. Symbols that should be avoided are triple dots, accents other than bars that extend over more than one character and double accents (e.g., a circumflex over a bar). Accents over characters can be eliminated by the use of such symbols as a prime ( ' ), an asterisk (*), or a dagger (??) set as superscripts.If the argument of an exponential is complicated or lengthy, "exp'' rather than e should be used. Awkward fractional composition can be avoided by the proper introduction of negative powers. In text, solidus fractions (l/r) should be used, and enough enclosures should be included to avoid ambiguity. According to the accepted convention, parentheses, brackets, and braces are in the order { [ ( ) ] }. Displayed equations should be numbered consecutively throughout the paper; the number (in parentheses) should be to the right of the equation. Displayed equations should be numbered consecutively throughout the paper; the number (in parentheses) should be to the right of the equation: (1), (2), and so forth. Chemical reactions may be numbered as displayed equations or may be numbered separately. If the latter option is chosen, the reaction number should be placed in parentheses to the left of the reaction: (R1), R2), etc. Notation. The notation is a list of symbols used in the text as an aid to the reader. It should be set up in this form: c   rate of soil accumulation, m/yr. d   median grain size of water-deposited material, ??m. D   distance of the locus of points, m. h   elevation of the rock stream channel at a particular time ti,, meters above base level. Hf   maximum vertical displacement of the fault associated with an earthquake, m. z   vertical coordinate of the model grid system. b   parameter computed by b = b/log10 e. g   mean peak flow rate above base flow of stream, m3/s. ??  A notation list is considered to be an appendix and appears at the end of the text, before acknowledgments and references. ??  The metric system must be used throughout; use of appropriate SI units is encouraged. Treatment of chemical names, symbols, conventions, and notation follows American Chemical Society style, as given in the ACS Style Guide. References. A complete and accurate reference list is of major importance. Omissions, discrepancies in the spelling of names, errors in titles, and incorrect dates make citations annoying, if not worthless, to the reader and cast doubt on the reliability of the author as well. Only works cited in the text should be included in the reference list. References are cited in the text by the last name of the author and the year: [Jones, 1990]. If the author's name is part of the sentence, only the year is bracketed. Personal communications and unpublished data or reports are not included in the reference list; they should be shown parenthetically in text: (F. S. Jones, unpublished data, 1990). References are arranged alphabetically by the last names of authors. Multiple entries for a single author are arranged chronologically. Two or more publications by the same author in the same year are distinguished by a, b, c after the year. For laboratory, company, or government reports, information should be included on where the report can be obtained. For Ph.D. and M.S. theses the institution granting the degree and its location should be given. References to papers delivered at meetings should include title of paper, full name of meeting, sponsor, meeting site, and date. Citations of papers presented at meetings have been complicated by the practice of collecting manuscripts from participants, reproducing the manuscripts, and distributing the collections to people attending the meeting. Such collections should not be cited as published works. References to books should include the page numbers of the material being cited. Names of periodicals should be either written out in full or abbreviated according to the system employed by the Chemical Abstracts Service. One-word titles should always be given in full: Science. It is permissible to give only the initial page number of a paper but preferable to give the range of pages. Samples: Beal, R.

Additional information on proper formats for various types of references may be found on AGU's Web site: http://www.agu.org/pubs/references.html. Refer to recent G3 papers for more examples. Tables. Tables should be formated as authors expect them to look online and in print. Every table must have a title, and all columns must have headings. Column headings must be arranged so that their relation to the data is clear. Footnotes should be indicated by lowercase letters typed as superiors. Each table must be cited in text. Authors are urged to make supporting data available as supplements, as described below. Illustrations. Figures should be submitted in one of the formats listed above. Figures not cluttered with information that could be placed in the caption look neater and are easier to read. All details on the figures should be checked carefully. Each figure must be cited in numerical order in text and must have figure caption. The use of color in figures is strongly encouraged. However, it is essential that no information be lost from color figures when they are printed in black and white as many readers will simply print the paper on a B/W printer. Copyright Material. It is the author's responsibility to obtain the necessary permission from the copyright holder to reproduce electronically any figures or tables taken from other publications. This includes any figures redrawn but basically unaltered or with only slight modifications. To avoid delays in publication, authors should obtain written permission from the copyright holder prior to submission of the final version of their manuscript for copy editing. The author should confirm that permission has been received at the time of submission and should immediately forward the permissions to AGU by regular mail. The figure cannot be published in G3 until permission to republish in electronic format is received from the copyright holder. Supplementary Material. Authors are encouraged to submit articles that are as concise as possible. Supporting material such as long tables, appendices, graphs, lengthy mathematical derivations, and extended background discussions can be handled through attached files that form appendices to the paper. This material can be in the form of text, tabular material, video or animations, and Mathematica notebooks. All supporting material will be subject to the same peer review as the article itself and must be in the appropriate format (see manuscript submission and formats). Decisions The editorial board of G3 is committed to the highest standards of publication as to both scientific content and clarity of presentation. The final decision on a manuscript is made solely by the Editor. The author will be notified by e-mail as soon as the Editor has made a decision.
