A 1999 survey collected station, catch, length, and biological data for 60 species across 66 stations in the Irish Sea and Bristol Channel. The survey was undertaken by Cefas using a 4m beam trawl research vessel from March 13 to March 27, 1999. Data was used to create abundance indices for EU regulations and an ICES research program, and also includes benthic, litter, water temperature, salinity, and acoustic data.
Use Cases
- Calculate species abundance indices based on catch and length data.
- Analyze benthic community composition based on collected biological and environmental data.
- Model relationships between water temperature, salinity, and fish distribution.
- Assess marine litter prevalence in the surveyed regions.
- Validate acoustic survey methods against trawl catch data.
Strengths
- Survey operations were undertaken on 66 stations, providing spatial coverage.
- 60 different species were caught, indicating taxonomic breadth.
- Data collection 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.
- Data may reflect temporal bias inherent to a single two-week survey in 1999.
