Cefas conducted the CORY 2/07 survey as part of the North West Groundfish Survey in Quarter 3. The survey collected station, catch, length, and biological data for 187 species across 108 stations in the Irish Sea and Bristol Channel between September 16 and October 6, 2007. Data supports EU regulations and ICES research, with additional aims to gather benthic, litter, water temperature, salinity, and acoustic data.
Use Cases
- Calculate abundance indices for groundfish species based on catch and length data.
- Analyze species distribution and community composition across 108 survey stations.
- Correlate biological data with environmental variables like water temperature and salinity.
- Support benthic habitat studies using the collected benthic data.
- Assess marine litter presence and distribution in the surveyed areas.
Strengths
- Survey operations were undertaken on 108 stations, providing spatial coverage.
- 187 different species were caught on this survey, indicating taxonomic breadth.
- Data collection spanned a defined period from 16/09/2007 to 06/10/2007.
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.
- Description metadata is limited; actual data quality requires manual inspection after download.
