Arctic Vegetation and Soil Data from Oumalik, Alaska Plots

ORNL_CLOUD provides environmental, soil, and vegetation data collected from 87 study plots near an abandoned test oil well in Oumalik, Alaska. The dataset captures conditions between 1983 and 1985, with attributes including dominant vegetation, species cover, soil chemistry, physical characteristics, and site disturbance. Sampling was designed to represent the full range of local vegetation with replication and uniformity in floristic composition.

Use Cases

• Analyzing correlations between soil chemistry attributes and dominant vegetation species across plots.
• Assessing the impact of site disturbance from various sources on vegetation cover and composition.
• Modeling soil moisture and organic matter content in relation to physical soil characteristics.
• Comparing floristic composition and environmental conditions across replicated sampling sites.
• Studying long-term ecological changes in Arctic regions following oil exploration activities.

Strengths

• Data is based on 87 replicated study plots, providing a structured sample of the area's vegetation range.
• Includes multiple measurement domains: vegetation species/cover, soil chemistry, physical characteristics, moisture, and disturbance.
• Sampling design aimed for uniformity in floristic composition and environmental conditions across plots.
• Time range is precisely documented as 1983 to 1985.

Limitations

• Exact row count, column names, and dataset size are not provided by any source.
• Sources conflict on the last updated date: one states 1985-08 -05, another states 2026-03-13, suggesting a metadata inconsistency.
