A survey conducted from September 5 to 27, 1989, on the research vessel Corystes in the Irish Sea and Bristol Channel. The survey was undertaken by Cefas as part of the North West Groundfish Survey, collecting station, catch, length, and biological data. It includes data on 77 species caught across 206 stations, supporting indices of abundance for EU regulations and ICES research.
Use Cases
- Calculate abundance indices for groundfish species based on catch data.
- Analyze species distribution and biodiversity across 206 survey stations.
- Model fish population dynamics using biological data for selected species.
- Study benthic ecosystem health based on the collection of benthic and litter data.
- Correlate fish abundance with environmental factors like water temperature and salinity.
Strengths
- Data covers 77 different species, providing a broad biodiversity snapshot.
- Survey operations were undertaken on 206 stations, offering spatial coverage.
- Includes multiple data types: station, catch, length, and biological data.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data is from a single survey in 1989; temporal scope is limited.
