A global dataset of coastal soil carbon measurements compiled to explore the relative contribution of local versus external carbon sources in tidal saltmarsh, mangrove, and seagrass wetlands. The data was used in a Bayesian hierarchical meta-regression model and is hosted by the Australian Ocean Data Network, last updated on 2026-07-16. The analysis found most soil organic carbon in these wetlands came from allochthonous sources rather than the habitat-forming plants.
Use Cases
- Modeling carbon source contributions in coastal wetlands based on the compiled global soil measurements.
- Assessing the impact of soil sampling depth and replication on carbon source estimates as outlined in the study.
- Informing management strategies for climate-resilient blue carbon seascapes based on the portfolio of carbon contributors identified.
Strengths
- Data is derived from a global compilation of coastal soil carbon measurements.
- Analysis employed a Bayesian hierarchical meta-regression model to explore carbon sources.
- Dataset covers three key coastal wetland types: tidal saltmarsh, mangrove, and seagrass.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic or methodological bias inherent to the compiled studies.
