CORY 11/96: North West Groundfish Survey Catch and Environmental Data

A 1996 survey conducted by Cefas aboard the Corystes between August 23 and September 16. It includes station, catch, length, and biological data for 84 species from 161 stations in the Irish Sea and Bristol Channel, collected using 4m beam trawls and a CTD profiler. The data supports EU regulations and ICES research programs.

Use Cases

• Calculate species abundance indices based on catch data from 161 stations.
• Analyze species length distributions for stock assessment mentioned in the description.
• Correlate fish catch data with environmental variables like water temperature and salinity.
• Study benthic community composition using the trawl survey data.
• Support marine litter research using the litter collection data mentioned.

Strengths

• Survey covers 161 stations, providing spatial breadth.
• Records data for 84 different species caught.
• Includes environmental data like water temperature and salinity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; last metadata update was 2026-06-11.
