Cefas CIRO 8/93: North Sea Groundfish Survey Data from 1993

189 stations were sampled during the 1993 North Sea Groundfish Survey, resulting in catches of 85 different species. The Centre for Environment, Fisheries & Aquaculture Science (Cefas) conducted this survey aboard the RV Cirolana between August and September 1993. Data includes station, catch, length, and biological information for fish, alongside benthic catches, water temperature, salinity, and litter records.

Use Cases

• Modeling fish stock composition based on annual trawl survey data.
• Analyzing species distribution patterns from catch data recorded at 189 stations.
• Studying benthic ecosystem interactions using recorded benthic catch information.
• Investigating environmental correlations using collected water temperature and salinity data.

Strengths

• Survey operations were undertaken on 189 stations, providing a substantial spatial sample.
• Catches included 85 different species, indicating broad taxonomic coverage.
• Data collection followed standardized International Bottom Trawl Survey (IBTS) protocols.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
