ASTAR Project: 2024 Arctic Sediment and Geomorphic Field Data for Alaska

June and July 2024 field data collected by the Alaska Division of Geological & Geophysical Surveys across an approximately 24,479 km2 area near Anaktuvuk Pass, Alaska. The dataset presents field station locations, observations, sediment sample descriptions, grain-size analyses, and links to photographs. This work was completed in support of a sand and gravel resource assessment for the Arctic Strategic Transportation and Resources (ASTAR) project.

Use Cases

• Mapping surficial deposit distribution based on field station observations and sample descriptions
• Analyzing sediment grain-size for construction material resource assessment
• Studying glacial, fluvial, and periglacial processes based on documented geomorphic features and sedimentary facies
• Community planning and land management based on the characterization of surface materials

Strengths

• Covers a large, defined study area of approximately 24,479 km2
• Includes multiple data types: locations, observations, sample descriptions, analyses, and photograph links
• Data collected by a state geological survey (Alaska DGGS) with support from a consulting firm

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
