Fisheries and Oceans Canada conducted the Coastal Biodiversity Trawl Survey for Passamaquoddy Bay annually from July to October between 2009 and 2019. The survey monitors long-term changes in species presence, habitat use, and health. Data collected prior to 2013 are generally not recommended for comparative analysis due to changes in vessel, sampling effort, and protocols.
Use Cases
- Monitor long-term species presence trends based on annual trawl surveys.
- Analyze habitat utilization patterns for coastal species.
- Assess ecosystem health changes over time for marine protected areas.
- Support aquaculture and fisheries research with coastal biodiversity data.
Strengths
- Annual survey conducted over 11 years (2009-2019).
- Data supports research in fisheries, aquaculture, marine protected areas, and ecosystem change.
- Includes a technical report (Can. Tech. Rep. Fish. Aquat. Sci. 3176) for additional context.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data from 2009-2012 is flagged for potential inconsistencies in vessel, effort, and protocol.
