Pacific Salmon and Pelagic Ecosystem Survey Data 1995-2022

1995 to 2011 surveys, with data from 2022, monitor the pelagic ecosystem in coastal and high seas waters of the Northeast Pacific. Fisheries and Oceans Canada collected this data through surface water trawl surveys, initially focusing on juvenile Pacific Salmon migratory patterns and physiology. The dataset includes records from continental slope waters deeper than 400 meters and the Gulf of Alaska.

Use Cases

• Analyze juvenile Pacific Salmon migratory patterns using trawl survey data from coastal and high seas locations.
• Monitor changes in the pelagic ecosystem composition over time using survey data from 1995-2011 and 2022.
• Study the growth and physiology of juvenile Pacific Salmon with data collected between 2003 and 2016.
• Compare continental slope water ecosystems at depths greater than 400 meters with other surveyed regions.

Strengths

• Data collection spans multiple decades, from 1992 to 2022, with a focused period from 1995 to 2011.
• Surveys cover a broad geographic area including British Columbia, Washington, Oregon, Alaska, and the Gulf of Alaska.
• The dataset scope expanded in 2016 to monitor the entire pelagic ecosystem, providing broader ecological context.

Limitations

• Specific row count, column names, and sample data are unavailable, limiting preliminary analysis.
• The core temporal coverage is 1995-2011, with only periodic updates like the 2022 survey, creating potential data gaps.
• Survey focus shifted over time (migratory patterns, physiology, ecosystem monitoring), which may affect data consistency for longitudinal studies.
