Sediment Core Grain Size Data from Wax Lake Delta Campaigns

Grain size distribution measurements from sediment core samples collected on Mike Island in the Wax Lake Delta, Louisiana. The dataset covers samples from the Delta-X Spring and Fall campaigns in March and August 2021, specifically from March 26, 29, and August 18, 24. Data were collected by NASA using a piston core and analyzed with a laser diffraction particle size analyzer.

Use Cases

• Analyzing sediment texture changes between spring and fall 2021 sampling campaigns.
• Modeling sediment transport and deposition in the Wax Lake Delta using grain size distributions.
• Calibrating remote sensing data from the Delta-X mission with ground-truth sediment core measurements.
• Studying the relationship between grain size and depositional environment in a prograding delta.

Strengths

• Data collected as part of the structured NASA Delta-X mission, ensuring methodological consistency.
• Provides specific sampling dates (March 26, 29; August 18, 24, 2021) for temporal analysis.
• Measurements obtained using a standardized laser diffraction particle size analyzer.

Limitations

• Conflicting 'last updated' dates: datagov lists 2026-03-13, while nasa_earthdata lists 2021-08-24.
• Key metadata such as row count, column names, and specific license terms are unavailable from all sources.
