Canada Ocean Biogeochemical Model Simulations 2015-2017

Monthly mean simulation results from 2015 to 2017 for Canada's Atlantic, Pacific, and Arctic Oceans. The dataset is derived from a moderate to high-resolution (≈0.25°, 75 levels) numerical model that assesses biogeochemical parameters. It was validated against satellite ocean color, surface pCO2, and depth profiles of oxygen and nitrate.

Use Cases

• Validate satellite-derived surface chlorophyll and particulate organic carbon data against model outputs for the 2015-2017 period.
• Analyze the impact of fluvial nutrients and colored dissolved organic matter (CDOM) on localized pCO2 reduction across the three ocean basins.
• Model the biological drawdown of dissolved inorganic carbon and nutrients in spring and summer using the optimal parameter set identified in the simulations.
• Assess the sensitivity of primary production and zooplankton biomass to processes like interactive sediments and iron limitation in diverse oceanic regions.

Strengths

• Covers a significant temporal span of three years (2015-2017) with monthly resolution.
• Model domain is spatially extensive, spanning Canada's three major oceans from 26°N to the Arctic.
• Validation incorporates multiple data sources including satellite, ship, and Argo float measurements.
• Simulations examine a range of specific biogeochemical processes like iron limitation and fluvial nutrient inputs.

Limitations

• The dataset's temporal coverage ends in 2017, which may limit analysis of recent oceanographic changes.
• As a model output, the data contains uncertainties inherent to the parameterizations and assumptions of the numerical simulation.
• Specific data volume (row/column counts) and granular sample data are not provided for direct assessment.
