Seasonal Salinity Climatology for Canadian Pacific EEZ (1980-2010)

1980-2010 seasonal salinity climatology for the Canadian Pacific Exclusive Economic Zone, derived from historical CTD, bottle, XBT, and Argo observations. The dataset provides high-resolution raster layers at 1/300 degree, with seasonal medians calculated across 65 subregions and up to 52 vertical levels down to 5000m.

Use Cases

• Model ocean circulation dynamics using high-resolution seasonal salinity layers for the Canadian Pacific EEZ.
• Analyze vertical salinity profiles across up to 52 depth levels to study stratification patterns.
• Compare seasonal median salinity values (Spring, Summer, Fall, Winter) across 65 subregions for climate trend analysis.
• Integrate salinity climatology raster layers with other oceanographic variables for habitat suitability modeling.

Strengths

• Covers a 31-year time period (1980-2010) for robust climatological averaging.
• High spatial resolution of 1/300 degree for detailed regional analysis.
• Data synthesized from multiple authoritative sources including NOAA, MEDS, and Institute of Ocean Sciences archives.
• Provides vertical coverage up to 52 levels from surface to 5000m depth.

Limitations

• Uncertainties introduced by spatial interpolation of observational data to varying distances.
• Temporal coverage ends in 2010, lacking recent observations.
• Seasonal definitions (e.g., Spring as April-June) may not align with all regional oceanographic models.
