d) Palabras Clave / Key Words: Maximum of 5 keywords in Spanish (palabras clave) which should be the same as in English (keywords).

e) Main text: Its overall structure will consist of introduction, results, discussion and conclusions. Tables and figures should be distributed consistent manner throughout the text, and always in accordance with the reference template.

f) Author contributions: For articles with several authors, this section should indicate, after each surname, the tasks performed by each author using the following activities or fields in which he/she contributes: Structure of the paper, methodology, data acquisition, editing, figures, manuscript revision, research/analysis, coordination, supervision.

g) Acknowledgements and funding: Express reference should be made to the sources of funding: "This work has been financed by the projects REFERENCE, REFERENCE, of... (indicate funding institution), by the grant (indicate institution and beneficiary author)". If no funding has been received, a sentence of the following type should be included: The present research has not received specific support from public sector agencies, commercial sector or non-profit organizations. Also add a text expressly citing personal acknowledgements and those to the identified or anonymous reviewers

h) References: They should be sorted alphabetically by authors(a maximum of 20 references). For manuscripts headed by the same author, the reference order will be the following: first, the papers by a single author and sorted chronologically; secondly, the manuscripts signed by 2 authors and first sorted alphabetically and, in the case of publications with the same co-authors, in chronological order; finally, the manuscripts signed by more than 3 authors sorted chronologically. In the case of journal articles, and abstract books of Meetings and Conferences, the title of the manuscript will be omitted. See the following examples:

h) Tables: They must be ordered consecutively with Roman numerals. Authors must ensure legibility once inserted in the reference template.

i) Figures: They should be numbered consecutively with Arabic numerals. All maps must contain a scale and geographic coordinates, and those figures and photographs deemed necessary must also contain a graphic scale. Authors should ensure the readability of each figure inserted in the reference template. For the design of the figures should be taken into account the maximum box size of the GEOGACETA pages (240 x175 mm), which in turn are divided into three columns. It is important to correctly choose the stroke widths of lines, text size, drawing pattern, etc., for optimum quality. The font type and size recommended for the realization of the figures is indicated on the template, which can be downloaded from the www.geogaceta.com. If a figure consists in turn of other figures and/or photographs, each must be named with a capital letter, beginning with the letter A and following letters in alphabetical order. Publish all of the manuscript pages in colour is possible (loose pages are not published in colour). When authors submit print proofs, they must apply colour printing of the manuscript and assume the corresponding amount. The inclusion of double or foldout pages (DIN A3) is also provided, whose extra cost should be also assumed by the authors. In these cases it is necessary to contact the editors previously.

j) Figure and table captions. They must be written in English and Spanish, as indicated in the reference template.

Editorial process/protocol

Manuscripts should be submitted using the reference template. This template is available in www.geogaceta.com for download. Manuscripts should be written in Spanish or English. The maximum extent of work may not exceed the equivalent of 4 printed pages of GEOGACETA, including figures, tables and references. A printed page of GEOGACETA contains about 6000 characters (including letters, symbols, and spaces between words). Authors must fill out a form stating that the data presented are original and have not previously been published. Authors must assign copyright to the SGE. Authors must propose five scientific reviewers (referees), indicating for each of them: name, institutional affiliation and e-mail. Manuscripts will be reviewed at least by two researchers -initially anonymous-, which must be experts in the subject of the manuscript.

GEOGACETA editors are responsible for managing the review of manuscripts. Editors are supported by members of the Scientific Board and by those researchers that for its prestige can act as reviewers. The list of reviewers is published each year in the number of the second semester. Reviewers must decide whether to be identified or remain anonymous. Once the reviewer comments are available, Editors will make a first decision on the manuscript, and all forms and comments made on the manuscript will be returned to the authors. Authors will have at least fifteen days to submit the revised version of the manuscript with the necessary modifications, together with a report of the changes introduced and possible discrepancies with the opinions expressed by the reviewers. Editors may request a second review of the manuscript.

Based on the reports and the quality of the revised manuscript, Editors will raise a report to the Advisory Board (composed by members of the Governing Board of the SGE), who will estimate finally whether or not the acceptance of the manuscript. The review date of the manuscript will coincide with that of the meeting of the Advisory Board. The Advisory Board will meet at least twice a year. The manuscript will be definitely accepted once it has been presented in a Scientific Session of the SGE (the approval date of the manuscript will coincide with that of the ending of the scientific session). In the case of the manuscript not being accepted, it will be returned to the author with a brief explanatory note of the reasons for that decision. Failure to comply with the aforementioned regulations for the preparation of the manuscript will be sufficient reason for rejection thereof.

Finally, prior to the final acceptance of the manuscript and to ensure optimum quality of the article, the authors must sent to Editors independently, in addition to the template, the text without figures or tables in a Word file and each one of the figures and tables in separate files. Image files and tables will be provided with sufficient resolution (minimum 300 dpi print size) in the following formats: JPG or TIFF.

The Scientific Board of GEOGACETA, through the Advisory Board, provides the ability to submit comments to published articles, which will be included in the "GEOGACETA DEBATE" section. Comments must be no longer than one printed page (6000 characters), and will be published along with the reply of the authors, also with a maximum length of one page. The submission of comments and replies will be made through www.geogaceta.com.
