Global Biogeochemical Cycles (global-biogeochemical-cycles)
Journal positioning
Global Biogeochemical Cycles (GBC) is the American Geophysical Union's journal for the cycling of carbon, nutrients, and elements through the earth system: the fluxes, budgets, and feedbacks that move and transform elements across land, ocean, and atmosphere, constrained by observations, experiments, and models. The defining expectation is a quantitative, system-scale advance in biogeochemistry — a better-constrained flux or budget, a newly characterized feedback, or a mechanism operating at regional-to-global scale — not a site-level process measurement of interest mainly to one community. A descriptive local incubation, a single-station time series, or an ecological/soil study with no implication for an element budget or earth-system feedback is a weak fit. This skill is a fit / venue-selection / re-framing tool. It does not replace the journal's current author guidance. Before submitting, re-check the live GBC / AGU author instructions and data policy.
