Protodune Dynamics with Wind and Sediment Data, Namib Desert, September 2023

British Geological Survey data includes raw point cloud data from repeat terrestrial laser scans for early-stage protodunes migrating and eroding on a gravel surface in the Helga's Interdune Area, Gobabeb, Namib Desert, Namibia. The dataset also contains nearby measurements of wind speed via a CSAT 3D sonic anemometer and sediment transport using a Sensit along with sediment trap data downwind of the focus protodune. The dataset was last updated on 2026-04-09.

Use Cases

• Modeling protodune migration rates based on repeat terrestrial laser scan data.
• Correlating wind speed measurements with observed sediment transport and erosion patterns.
• Analyzing the relationship between 3D dune morphology changes and downwind sediment trap data.

Strengths

• Includes multi-modal data: terrestrial laser scans, wind speed, and sediment transport measurements.
• Focuses on a specific, well-defined location and event (Helga's Interdune Area, 12th September 2023).

Limitations

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