106,000 species-level records from research trawls and fisheries surveys conducted by CSIRO Division of Marine and Atmospheric Research in waters around Australia. Data collection began in the late 1970s and the repository was active through 2006. Associated data include species counts and weights for some records.
Use Cases
- Analyze species occurrence patterns across Australian coastal regions using species-level records.
- Model population trends over time using species count data from repeated trawl surveys.
- Assess biomass distribution in fisheries surveys using associated species weight records.
- Study long-term changes in marine biodiversity from survey data spanning decades.
Strengths
- 106,000 species-level records provide a substantial baseline for analysis.
- Data collection spans from the late 1970s to at least 2006, offering multi-decadal temporal coverage.
- Records originate from systematic research trawls conducted by a national scientific agency.
Limitations
- Multiple species records and taxa not identified to species level are excluded, limiting taxonomic completeness.
- Associated species count and weight data are not present for all records.
- The dataset's last documented update was in 2006, indicating potential staleness.
