Cefas conducted the CIRO 2/89 survey as part of the North Sea Groundfish Survey in Quarter 1. The survey collected station, catch, length, and biological data for 61 species across 191 stations between January 27 and February 22, 1989, aboard the RV Harvester. Additional aims included gathering benthic, water temperature, salinity, and litter data using GOV trawls and other specified equipment.
Use Cases
- Modeling groundfish stock assessments based on catch and length data for 61 species.
- Analyzing species distribution and biodiversity across 191 survey stations in the North Sea.
- Studying correlations between fish populations and environmental variables like water temperature and salinity.
- Investigating benthic community composition and marine litter data collected during the survey.
Strengths
- Survey operations were conducted at 191 distinct stations, providing spatial coverage.
- Data includes 61 different species caught, indicating biodiversity coverage.
- Collection includes multiple data types: biological, environmental (temperature, salinity), and benthic.
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.
