CIRO 2/86: North Sea Groundfish Survey with Benthic and Environmental Data

203 stations were sampled during a February 1986 survey aboard the Cirolana, catching 54 different species. The dataset contains station, catch, length, and biological data for selected species, collected using GOV trawls as part of the International Bottom Trawl Survey. It also includes benthic, water temperature, salinity, and litter data, supporting EU data regulations.

Use Cases

• Modeling species distribution and abundance based on catch and station data.
• Analyzing relationships between fish populations and environmental conditions based on temperature and salinity data.
• Studying benthic community composition and marine litter based on the additional collected data.

Strengths

• Data from 203 sampled stations provides spatial coverage.
• Includes 54 different species, offering multi-species context.
• Integrates biological catch data with environmental (temperature, salinity) and benthic measurements.

Limitations

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