Shrimp Density and Biomass in a Louisiana Salt Marsh

This dataset provides biological and environmental measurements from a salt marsh in Caminda Bay, Grand Isle, Louisiana. It contains count, measurement, and weight data for Penaeid shrimp species, alongside environmental, habitat, and vegetation information. The data was collected by NOAA NCEI to evaluate how aquatic fauna use the marsh surface during flood tides.

Use Cases

• Comparing animal densities between vegetated marsh surfaces and non-vegetated marsh edges.
• Analyzing shrimp total length, biomass, and count data for species like Farfantepenaeus aztecus (brown shrimp) and Litopenaeus setiferus (white shrimp).
• Correlating shrimp presence and size with concurrent environmental, habitat, and vegetation measurements.

Strengths

• Data collection employed a standardized 1.8 m diameter drop trap sampler for density estimates.
• Focuses on two ecologically and commercially important Penaeid shrimp species.
• Includes complementary environmental and habitat data for ecological context.

Limitations

• Key structural information like column names, row count, and file size is unavailable from all sources.
• Sources conflict on the 'last updated' date, reporting both 1988-10-19 and 2026-04-01.
• The specific license governing reuse is not stated.
