Protodune Dynamics with Wind and Sediment Data from Great Sand Dunes, April 2023

April 3, 2023 data from repeat terrestrial laser scans (TLS) capturing early-stage protodune development on a moist sandy surface in the Medano Creek area of Great Sand Dunes National Park, Colorado, USA, under very strong winds. The dataset includes raw point cloud data from TLS alongside nearby measurements of wind speed via a CSAT 3D sonic anemometer and sediment transport using Sensit and Wenglor fork sensors. It was contributed by the British Geological Survey (BGS) and last updated on the platform in April 2026.

Use Cases

• Modeling protodune evolution based on high-resolution topographic change data from repeat TLS scans.
• Correlating sediment transport rates with wind speed measurements from the CSAT 3D sonic anemometer.
• Analyzing surface dynamics on moist sandy substrates under strong wind conditions as described.

Strengths

• Includes multi-sensor data: terrestrial laser scans, 3D sonic anemometer, and sediment transport sensors.
• Captures a specific, high-energy geomorphic event (very strong winds) on a single day, April 3, 2023.
• Data is from a defined and notable geographic location: Great Sand Dunes National Park, Colorado.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
• The single-day temporal coverage may limit analysis of longer-term dune dynamics.
