Cefas CIRO 9/92: North Sea Groundfish Survey with Species and Environmental Data

A survey conducted between 14 August 1992 and 10 September 1992 by the Centre for Environment, Fisheries & Aquaculture Science (Cefas) aboard the RV Cirolana. It includes data from 150 stations, recording 81 different species, benthic catches, water temperature, and salinity as part of the International Bottom Trawl Survey. The data was collected to support EU data regulations and provide distribution and stock composition estimates for fish species.

Use Cases

• Modeling fish stock composition based on the catch and length data collected.
• Analyzing species distribution patterns across the 150 survey stations.
• Studying benthic community structure based on recorded benthic catches.
• Correlating fish presence with environmental variables like water temperature and salinity.

Strengths

• Data from 150 stations provides a substantial spatial sample for the survey period.
• Records 81 different species, suggesting a broad taxonomic coverage.
• Includes complementary environmental data (temperature, salinity) alongside biological records.

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.
