CIRO 3/83: North Sea Groundfish Survey with Catch and Environmental Data

A marine survey conducted by Cefas on the vessel Cirolana between February 15 and March 5, 1983. The survey includes station, catch, length, and biological data for 44 species across 133 stations in the North Sea. Additional aims included the collection of benthic, water temperature, salinity, and litter data.

Use Cases

• Analyzing species composition and abundance based on catch data for 44 species.
• Modeling fish population dynamics using length and biological data for selected species.
• Studying historical environmental conditions based on collected water temperature and salinity data.
• Investigating benthic community interactions mentioned in the survey description.
• Assessing spatial distribution of marine life across the 133 survey stations.

Strengths

• Covers 133 distinct sampling stations, providing spatial breadth.
• Records data for 44 different marine species caught during the survey.
• Includes multiple data types: catch, biological, and environmental measurements.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
