Alaskan Tree Ring Anatomy Data from the 1783 Laki Eruption

Tree ring parameters provide a quantitative wood anatomy record from Northeast Alaska. The data covers the period from 1782 to 152 calendar years before present, focusing on the environmental impact of the 1783-1784 Laki volcanic eruption. This paleoclimatology study is archived and maintained by NOAA National Centers for Environmental Information.

Use Cases

• Analyze changes in tree ring cell structure parameters as a proxy for volcanic-induced climate stress during the Laki eruption period.
• Correlate quantitative wood anatomy features with known historical temperature and growing season anomalies following the 1783 event.
• Establish a dated tree-ring chronology for Northeast Alaska using the provided calendar years before present (BP) time coverage.

Strengths

• Data is sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides a specific temporal focus on a major historical volcanic eruption (1783-1784 Laki).

Limitations

• The exact number of tree core samples, rows of data, and specific measured parameters are unknown.
• Geographic coverage is limited to a single region in Northeast Alaska, limiting broader spatial analysis.
• The last update date (1798) is anomalous and suggests metadata issues regarding data currency.
