Seasonal Temperature Climatology of the Canadian Pacific EEZ (1980-2010)

1980-2010 seasonal temperature climatology for the Canadian Pacific Exclusive Economic Zone, derived from historical CTD, bottle, XBT, and Argo observations. The data are presented as high-resolution raster layers, with seasonal averages calculated as medians across 65 subregions and up to 52 vertical levels down to 5000m. It was produced by Fisheries and Oceans Canada using data from NOAA, MEDS, and IOS archives.

Use Cases

• Model vertical temperature profiles across up to 52 depth levels to study ocean stratification in the EEZ.
• Analyze seasonal temperature patterns across 65 subregions for marine habitat and ecosystem studies.
• Use the high-resolution (1/300 degree) raster layers as a baseline for climate change impact assessments in the Northeast Pacific.
• Compare median seasonal temperature values (Spring, Summer, Fall, Winter) to identify long-term thermal trends from 1980 to 2010.

Strengths

• Covers a 31-year time series (1980-2010) providing a long-term climatological baseline.
• High spatial resolution of 1/300 degree for detailed geospatial analysis within the EEZ.
• Data integrated from multiple authoritative oceanographic sources including NOAA, MEDS, and IOS archives.
• Vertical analysis spans up to 52 levels from the surface to 5000 meters depth.

Limitations

• Uncertainties are introduced due to spatial interpolation of observations to varying distances from measurement points.
• The 1980-2010 reference period may not reflect recent ocean warming trends post-2010.
• Specific sample size (row count) and data volume are not provided in the input.
