DFO Maritimes Research Vessel Invertebrate Trawl Survey Records

DFO Maritimes Research Vessel Trawl Surveys Invertebrate Observations contains selected invertebrate species records from Canadian Department of Fisheries and Oceans research trawl surveys. The data collection began in 1999. This OBIS-formatted view is provided by OBIS Canada and sourced from the NASA Earthdata platform.

Use Cases

• Model invertebrate species distribution using geospatial coordinates and survey year.
• Analyze long-term population trends for specific invertebrate taxa from 1999 onward.
• Assess biodiversity and community composition across different trawl survey locations.
• Validate marine habitat models with observed presence records of benthic invertebrates.

Strengths

• Systematic recording of invertebrates began in 1999, providing a multi-year baseline.
• Data is formatted to OBIS standards, facilitating integration with global biodiversity databases.
• Records originate from standardized DFO Maritimes research vessel trawl surveys.

Limitations

• The dataset includes only selected invertebrate species, not a complete census.
• Specific row count, column details, and sample size are unknown.
• The exact temporal endpoint and update frequency are not specified.
