Cefas conducted the CEND 13/09 survey as part of the North West Groundfish Survey in September 2009. The dataset includes station, catch, length, and biological data for 245 species collected from 126 stations in the Irish Sea and Bristol Channel using research vessels and 4m beam trawls. Data were used to create abundance indices for EU regulations and an ICES research program.
Use Cases
- Calculate species abundance indices based on catch data from 126 stations.
- Analyze biological parameters for selected species mentioned in the description.
- Model benthic community composition based on trawl survey data.
- Correlate water temperature and salinity data with species distribution.
- Assess marine litter prevalence in the Irish Sea and Bristol Channel.
Strengths
- Data covers 245 different species caught during the survey.
- Survey operations were undertaken on 126 stations, providing 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.
- Freshness should be verified; last metadata update was 2026-06-11.
