Delta-X Turbidity and Pressure Measurements in Mississippi River Delta 2021

Turbidity, absolute pressure, and temperature measurements were collected from 13 sites across the Atchafalaya and Terrebonne Basins in coastal Louisiana during Spring and Fall 2021. This dataset supports NASA's 5-year Delta-X mission to model sediment transport and predict land loss or gain in the Mississippi River Delta. Data are provided in CSV files.

Use Cases

• Modeling sediment transport dynamics by analyzing turbidity readings across island edges and wetland interiors.
• Calibrating airborne remote sensing data with ground-truth measurements of water pressure and temperature.
• Studying the impact of hydrodynamic conditions on deltaic sedimentation patterns using time-series sensor data.
• Assessing water quality changes in response to seasonal variations in the Mississippi River Delta.

Strengths

• Data collection targeted 13 distinct sites across two river basins to sample varied hydrodynamic conditions.
• Measurements cover two seasonal campaigns in Spring (March-April) and Fall (August) of 2021.
• Dataset is part of a structured 5-year NASA Earth Venture Suborbital mission (Delta-X) with clear scientific objectives.
• Cross-platform presence on NASA Earth Data and Data.gov indicates formal curation and importance.

Limitations

• Critical metadata conflicts exist: row counts, file sizes, and specific column names are not provided by any source.
• License is ambiguously listed as 'other-license-specified' without explicit terms.
• Last updated date shows a significant discrepancy between 2021 08 27 and 2026 03 13 across platforms.
