Biogeosciences (BG) is a not-for-profit international scientific journal dedicated to the publication and discussion of research articles, short communications, and review papers on all aspects of the interactions between the biological, chemical, and physical processes in terrestrial or extraterrestrial life with the geosphere, hydrosphere, and atmosphere. The objective of the journal is to cut across the boundaries of established sciences and achieve an interdisciplinary view of these interactions. Experimental, conceptual, and modelling approaches are welcome.

Journal metrics

BG is indexed in the Web of Science, Scopus, Google Scholar, etc. We refrain from displaying the journal metrics prominently on the landing page since citation metrics used in isolation do not describe importance, impact, or quality of a journal. However, these metrics can be found on the journal metrics page.

20 Oct 2025 Press Release: Invisible poison – Airborne mercury from gold mining is contaminating African food crops, new study warns

In a recent study published in BG, scientists have confirmed that mercury pollution from artisanal and small-scale gold mining (ASGM) is contaminating food crops not through the soil, as previously believed, but directly from the air. Please read more.

08 Oct 2025 Press Release: Record-breaking 2024 Amazon fires drive unprecedented carbon emissions and ecosystem degradation

A new study by researchers at the European Commission's Joint Research Centre reveals that the Amazon rainforest has just undergone its most devastating forest fire season in over two decades, which triggered record-breaking carbon emissions and exposed the region's growing ecological fragility despite a slowing trend in deforestation. Please read more.

31 Jul 2025 Disentangling future effects of climate change and forest disturbance on vegetation composition and land surface properties of the boreal forest

Disturbances, such as fire, can change which vegetation grows in a forest, affecting water and carbon flows and, thus, the climate. Disturbances are expected to increase with climate change, but it is uncertain by how much. Using a simulation model, the authors studied how future climate, disturbances, and their combined effect impact northern (high-latitude) forest ecosystems. Please read more.

Notice on the current situation in Ukraine

To show our support for Ukraine, all fees for papers from authors (first or corresponding authors) affiliated to Ukrainian institutions are automatically waived, regardless if these papers are co-authored by scientists affiliated to Russian and/or Belarusian institutions. The only exception will be if the corresponding author or first contact (contractual partner of Copernicus) are from a Russian and/or Belarusian institution, in that case the APCs are not waived.

In accordance with current European restrictions, Copernicus Publications does not step into business relations with and issue APC-invoices (articles processing charges) to Russian and Belarusian institutions. The peer-review process and scientific exchange of our journals including preprint posting is not affected. However, these restrictions require that the first contact (contractual partner of Copernicus) has an affiliation and invoice address outside Russia or Belarus.
