Description
The North Sea survey collected data from 117 stations between August 8 and September 8, 2002, aboard the RV Cirolana. It was undertaken by the Centre for Environment, Fisheries & Aquaculture Science (Cefas) as part of the International Bottom Trawl Survey. The survey recorded 156 different species, aiming to provide distribution and stock composition estimates for fish species.
Use Cases
Modeling fish species distribution and abundance based on trawl station data.
Analyzing stock composition and biological parameters for selected species.
Studying benthic ecosystem composition based on recorded benthic catches.
Correlating environmental factors like water temperature and salinity with catch data.
Strengths
Data collected from 117 specific stations, providing spatial granularity.
Records 156 different species, indicating broad taxonomic coverage.
Survey conducted over a defined one-month period in 2002, providing temporal specificity.
Includes biological data for selected species and environmental measurements like temperature and salinity.
