CORY 12B/00: 2000 Irish Sea and Bristol Channel Groundfish Survey Data

166 stations were sampled during a 22-day survey aboard the Corystes in late 2000. This dataset contains catch, length, and biological data for 86 species, collected by the Centre for Environment, Fisheries & Aquaculture Science (Cefas) to create abundance indices for EU regulations and ICES research. Additional aims included collecting benthic, litter, water temperature, salinity, and acoustic data.

Use Cases

• Modeling groundfish population indices based on catch and length data.
• Analyzing benthic community composition based on grab and beam trawl samples.
• Studying environmental conditions based on water temperature and salinity profiles.
• Investigating marine litter distribution from the survey's litter data collection.

Strengths

• Survey operations were undertaken on 166 stations, providing a detailed spatial sample.
• 86 different species were caught, indicating broad taxonomic coverage.
• Data collection used standardized gear including a 4m beam trawl and CTD profiler.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Last update date is unknown; freshness unverified.
