Longline Trap Survey of Demersal Fish in DeSoto Canyon 2015

March 30 to April 23, 2015 data from the R/V Apalachee cruise AP-1503 in the DeSoto Canyon, Gulf of Mexico. The dataset contains biological measurements and environmental data from fish traps and demersal longlines, collected to examine species assemblage and relative abundance differences. It is provided by the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing species assemblage and relative abundance using recorded species data.
• Studying fish biology and growth patterns with recorded length and weight measurements.
• Mapping survey locations and environmental gradients using latitude, longitude, and depth columns.
• Investigating gear and bait effectiveness for demersal fish sampling.
• Correlating fish catch data with recorded water temperature at set locations.

Strengths

• Data covers a specific 25-day research cruise with a clear temporal boundary (March 30 to April 23, 2015).
• Includes multiple data dimensions: biological (length, weight), spatial (lat/lon), and environmental (depth, temperature).
• Cross-platform presence on Data.gov and NASA EarthData indicates recognized importance and curation.

Limitations

• Critical metadata conflicts: row count, file size, and specific column names are unknown across all sources.
• License and author information are not provided, restricting clarity on reuse permissions.
• Biological data (length, weight) is noted as being for 'some species', indicating potential incompleteness.
