Arctic Basin Maps of Vegetation and Physiographic Features

Maps provide vegetation, landscape, geobotanical, elevation, hydrology, and geologic data for Alaska's Kuparuk River Basin. The collection covers the entire basin from the Brooks Range to the Beaufort Sea coast, as well as the Upper Kuparuk River Region including Toolik Lake. Data was produced from imagery and existing maps spanning over three decades.

Use Cases

• Analyzing vegetation cover and dominant species distribution across an Arctic watershed.
• Studying the relationship between glacial landforms, terrain elevation, and surface water features.
• Monitoring long-term landscape ecology changes from 1976 to 2008 using geobotanical maps.
• Comparing physiographic features between the coastal and mountainous regions of the North Slope.

Strengths

• Covers a large, significant Arctic basin from headwaters to coast.
• Includes data from two specific, well-known research areas: Toolik Lake and Imnavait Creek.
• Temporal coverage spans over 32 years (1976-08-04 to 2008-12-31).

Limitations

• Specific column names, row counts, and file sizes are not provided by any source.
• Sources conflict on the last updated date (2008-12 31 vs. 2026-03-13), suggesting possible metadata inconsistency.
