Get your Global Biogeochemical Cycles paper right the first time: a ready-made structure with the right abstract and citations, so editors see your science, not formatting slips.

Submitting to Global Biogeochemical Cycles goes smoothly when your draft already matches the journal's own rules. Editors screen new manuscripts against the Global Biogeochemical Cycles guide for authors before peer review, so formatting, structure, and required statements should be right on the first draft rather than repaired during upload. This template sets that structure up for you.
It is a manuscript shell aligned to Global Biogeochemical Cycles. It covers front matter, the abstract the journal expects, a body organized to the journal's article types, and a reference list in the journal's required style. Confirm current scope and article types on the Global Biogeochemical Cycles journal page before you draft.
Prepare the title, authors, affiliations, and ORCID iDs. Write the abstract to the journal's rule and word limit, organize the body to the article type, and apply the required reference style from the first citation. Complete every declaration (ethics, competing interests, funding, data availability) the Global Biogeochemical Cycles guide for authors lists, and cite figures and tables in order.
The common failure modes are formatting or reference style that does not match the guide for authors, missing required statements, and an incomplete portal checklist. Clear all three against the Global Biogeochemical Cycles guide for authors before you submit.
The shell mirrors what editorial staff check first: article-type fit, the abstract rules, required declarations, and the journal's reference style. For more detail see the author resources. When your draft is ready, upload it through the journal's submission system.
| Element | Global Biogeochemical Cycles requirement |
|---|---|
| Abstract | Unstructured abstract, set as a single paragraph. Word limit: less than 250 words. Must not include table or figure mentions. Avoid reference citations unless dependent on or directly related to another paper (e.g., companion, comment, reply, or commentary). Must define all abbreviations |
| Main text | Research articles: maximum 25 publication units (PU), where PU = (words/500) + number of figures + number of tables. Word count includes abstract, acknowledgements, text, in-text citations, figure captions, table captions, and appendices. Excludes title, authors, affiliations, key points, keywords, plain language summary, table text, open research section, references, and supporting information. Review articles incur excess page fees after 30 PUs. Commentaries limited to 6 PUs (approximately 2000 words and 1-2 figures) |
| Declarations | Ethics approval/consent as applicable; competing interests; funding; data availability |
| Figures/tables | Publication-ready; cited in order |
| Supplemental | Upload separately when used |
| Keywords | Up to 5 index terms from the AGU Index Set (terms ending in '00' not allowed) and up to 6 additional keywords (free-form, not included in word count) |
| References | Name-date format (e.g., Zhu et al., 2016 or Zhu et al. (2009)), with parenthetical in-text citations. Numbered references are not permitted |
| Peer review | Single-blind (single-anonymized): authors' names are visible to editors and reviewers, but reviewers' names are kept confidential from authors (unless reviewers choose to disclose their identity) |
| Submission | gbc-submit.agu.org/cgi-bin/main.plex |
Read the Global Biogeochemical Cycles guide for authors once before drafting and once before upload. Draft the abstract after results are stable. Set the reference style before adding citations. Keep a cover letter that states your contribution and fit to Global Biogeochemical Cycles in under a page.
Skim two or three recent Global Biogeochemical Cycles papers to calibrate depth and figure style. Make the novelty clear in the first two pages. Deposit data and code when the policy on the Global Biogeochemical Cycles journal page requires it. Disclose any preprint or conference version with identifiers in the cover letter.
Do one focused pass against the Global Biogeochemical Cycles guide for authors: scope, length, reference style, required declarations, and figure quality. Then submit through the journal's submission system.
