CIRO 2/88: North Sea Groundfish Survey with Benthic and Environmental Data

156 stations were sampled during a 20-day survey in February 1988 aboard the Cirolana, catching 58 different species. The dataset includes station, catch, length, and biological data for selected species, collected using GOV trawls as part of the International Bottom Trawl Survey. Additional aims involved gathering benthic, water temperature, salinity, and litter data.

Use Cases

• Analyzing species distribution and abundance based on catch and station data
• Studying fish biology and population structure based on length and biological data for selected species
• Investigating relationships between fish communities and environmental conditions based on water temperature and salinity data
• Assessing benthic community composition and marine litter based on the survey's additional aims

Strengths

• Covers 156 sampling stations, providing spatial breadth
• Records data for 58 different species caught
• Includes multiple data types: catch, biological, and environmental 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
