Seasonal Dissolved Inorganic Carbon Climatology for the Canadian Pacific EEZ (1993-2020)

Fisheries and Oceans Canada provides seasonal mean dissolved inorganic carbon concentration climatology for the Canadian Pacific Exclusive Economic Zone. The data were generated by averaging results from the British Columbia continental margin model (BCCM) over the 1993 to 2020 period. It includes raster layers at 3 km spatial resolution and 47 vertical levels from the surface to 2400 meters.

Use Cases

• Modeling ocean carbon uptake and acidification based on seasonal climatology data.
• Analyzing vertical and cross-shore gradients of dissolved inorganic carbon based on the 47-level depth profiles.
• Studying seasonal cycles in marine chemistry based on spring, summer, fall, and winter averages.
• Validating regional oceanographic models against a long-term (1993-2020) climatological benchmark.

Strengths

• Data spans a 28-year period from 1993 to 2020, providing a long-term climatological baseline.
• Model results have been evaluated against observations like altimetry and CTD profiles, showing reasonable accuracy for main oceanographic features.
• Includes data at up to 47 vertical levels from the surface to 2400 meters and the sea bottom.

Limitations

• The 3 km model resolution is too coarse to adequately represent inlets, nearshore areas, and the Strait of Georgia.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
