Arctic Marine Sediment Organic Carbon Burial Hotspots with Over 13,000 Samples

Over 13,000 sediment samples from the Arctic and sub-Arctic regions, analyzed using quantile regression forests. The dataset includes sediment organic carbon for surface sediments and down-core to 1 meter depth, with predictor variable layers sourced from external repositories. It was created by Nick Kamenos and last updated on 2026-05-27.

Use Cases

• Identify marine sediment carbon hotspots based on organic carbon accumulation rates.
• Model the relationship between carbon burial and environmental predictors like salinity and primary production.
• Assess the risk to carbon stores from anthropogenic disturbance based on marine protected area coverage.
• Analyze the role of coupled land-ocean processes, such as river transport, in carbon sequestration.

Strengths

• Includes over 13,000 sediment samples, providing a substantial observational basis.
• Combines surface and down-core (to 1 m) organic carbon measurements.
• Links to external predictor variable layers for multivariate analysis.

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 bias inherent to the sampled Arctic and sub-Arctic seas.
