A 1994 marine survey conducted by the Centre for Environment, Fisheries & Aquaculture Science (Cefas) as part of the International Bottom Trawl Survey. The survey recorded data from 147 stations over 25 days in August 1994, catching 86 different species. It collected station, catch, length, biological, benthic, water temperature, salinity, and litter data using research vessels and standardized trawls.
Use Cases
Modeling fish species distribution and abundance based on trawl station data.
Analyzing stock composition estimates for commercial fish species based on catch and length data.
Studying benthic ecosystem interactions based on recorded benthic catches.
Correlating fish populations with environmental factors based on collected water temperature and salinity data.
Strengths
Data collected from 147 stations, providing a detailed spatial sample.
Records for 86 different species, indicating broad taxonomic coverage.
Survey conducted over a defined 25-day period in August 1994, providing a temporal snapshot.
Includes multiple data types: catch, biological, length, benthic, and environmental measurements.
