CORY 10A/97: 1997 Irish Sea and Bristol Channel Groundfish Survey

Irish Sea and Bristol Channel survey data collected by the Centre for Environment, Fisheries & Aquaculture Science (Cefas) between 15 September and 6 October 1997. The survey was part of the North West Groundfish Survey program, covering 186 stations and recording catches of 207 species. Data were gathered using 4m beam trawls and other equipment to support EU regulations and ICES research.

Use Cases

• Calculate indices of fish abundance based on station and catch data mentioned in the description
• Analyze species composition and biodiversity from the 207 species recorded
• Study benthic community characteristics based on the collection of benthic data
• Correlate environmental factors like water temperature and salinity with species distribution

Strengths

• Data collected over 186 stations, providing spatial breadth for the survey area
• Records for 207 different species, indicating detailed taxonomic coverage
• Includes multiple data types: station, catch, length, biological, benthic, 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
