Pollen Sequences Before and After Volcanic Eruptions in Northeastern China

130.7 KB of pollen sequence data in an XLSX file, comparing periods before and after two volcanic eruptions in northeastern China and including sequences from human disturbance. The dataset was authored by Yong Luo and last updated on May 31, 2026. It is shared under a CC-BY-4.0 license on figshare.

Use Cases

• Assessing vegetation change following volcanic eruptions based on pollen sequences.
• Comparing natural disturbance impacts from volcanoes versus anthropogenic disturbances.
• Reconstructing historical landscapes in northeastern China using pollen data.

Strengths

• Data is focused on a specific geographic region (northeastern China) and event type (volcanic eruptions).
• The dataset is structured to enable direct before-and-after comparisons of two distinct volcanic events.
• It is shared under a permissive CC-BY-4.0 license for reuse.

Limitations

• The dataset is small at 130.7 KB, indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
