Blue Carbon Export Pathways from Kelp and Seagrass in Nova Scotia

Modeled export from coastal vegetated ecosystems shows variability by orders of magnitude across spatial scales, species, seasons, and carbon forms. The data reveals rapid export of dissolved organic carbon to the shelf break, contrasting with sinking particulate carbon that remains nearshore. This dataset, published in Science Advances in 2025, originates from Fisheries and Oceans Canada and was last updated in March 2026.

Use Cases

• Modeling carbon sequestration rates based on export pathways for kelp and seagrass.
• Analyzing spatial variability in carbon export across scales from 3 to hundreds of kilometers.
• Comparing export patterns of dissolved organic carbon versus particulate organic carbon.
• Calibrating regional blue carbon accounting frameworks to avoid generalized export rates.

Strengths

• Data is associated with a peer-reviewed publication in Science Advances (2025).
• Modeling covers multiple spatial scales, species, seasons, and carbon forms.
• Last updated on 2026-03-24, indicating recent maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
