Total Suspended Solids Concentration in Atchafalaya and Terrebonne Basins, 2021

Field measurements of total suspended solids concentrations were collected from surface waters in the Atchafalaya River and Terrebonne Basins during spring and fall 2021. The dataset, part of the NASA Delta-X project, captures water quality across channels, bays, lakes, and nearshore Gulf of Mexico sites. Sampling was interrupted by Hurricane Ida, providing a record of conditions before and after a major storm event.

Use Cases

• Analyzing sediment load variations between spring and fall seasons in coastal Louisiana.
• Modeling the impact of hurricane events, like Ida, on near-surface water turbidity.
• Calibrating remote sensing data for total suspended solids using in-situ field measurements.
• Studying spatial distribution of particulates across river channels, open bays, and nearshore waters.

Strengths

• Provides temporally specific data from two distinct field campaigns spanning March to April and August to September 2021.
• Covers a diverse range of aquatic environments, from narrow channels a few meters wide to open bays and the Gulf of Mexico.
• Documents sampling protocol disruption and recovery from Hurricane Ida, offering context for data continuity.

Limitations

• Exact row count, column names, and dataset size are not provided by any source.
• Sources conflict on the last updated date, listing both 2021-09-24 and 2026-03 13.

NASA Delta-X project, with organization listed as ORNL_CLOUD.

Collection Method

Water samples were collected from approximately 0.5 meters depth, filtered, and the retained particles were weighed after drying to calculate concentration.
