Description
Cefas conducted the CIRO 4/98 survey as part of the North Sea Groundfish Survey in the third quarter of 1998. The survey, carried out on the vessel Cirolana between August 14 and September 14, 1998, completed operations at 200 stations and recorded 162 different species. Data collected includes station, catch, length, and biological information for fish, as well as benthic catches, water temperature, salinity, and litter data.
Use Cases
Modeling fish stock composition and distribution based on catch and length data.
Analyzing benthic community structure based on recorded benthic catches.
Studying correlations between environmental factors like water temperature and salinity with species presence.
Supporting international fisheries management and EU data regulations with standardized trawl survey data.
Strengths
Survey operations were undertaken on 200 stations, providing a substantial spatial sample.
Records data for 162 different species caught, indicating broad taxonomic coverage.
Collects multiple data types including biological samples, environmental measurements (temperature, salinity), and litter data.
