Deep-Sea Coral Genetic Identification from West Coast Groundfish Surveys

A 2012 West Coast Groundfish Bottom Trawl Survey project by the NOAA Northwest Fisheries Science Center to create a DNA sequence repository and voucher collection for coral and sponge species. The data is linked to the groundfish survey database and aims to support research on the biogeography and ecology of deep-sea coral communities. The dataset is represented by the 'Deep Sea Coral voucher sequence dataset'.

Use Cases

• Taxonomic identification of coral species based on DNA sequence data mentioned in the description
• Population-level genetic analysis of deep-sea octocorals based on microsatellite loci mentioned in the description
• Biogeographic and ecological research on deep-sea communities based on linked survey specimen data
• Creating a verified specimen and genetic data repository for future research as stated in the project goals

Strengths

• Data is linked to the established West Coast Groundfish Bottom Trawl Survey database.
• Project involves verified specimen vouchers and DNA sequencing for taxonomic accuracy.
• Aims to serve as a foundational resource for future research at the NWFSC.

Limitations

• Row count and column definitions are unknown, limiting suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
• The dataset title is marked as 'OBSOLETE', which may indicate outdated or superseded content.
