Data Description: Monthly mean simulation results from Canada's three Oceans model (sensitivity experiments--2017). Experiment codes can be matched to specific parameter sets following Table 1 in Christian et al 2026 from Canadian Technical Report of Fisheries and Aquatic Sciences 3721. Abstract from the report: A numerical ocean model with biogeochemistry has been developed for a domain that spans Canada's three oceans: the Atlantic, Pacific and Arctic. The domain extends to 26°N in the Atlantic and 44°N in the Pacific, and spans the full width of each basin as well as the whole of the Arctic Ocean. The resolution is moderate to high (≈0.25°, 75 levels). A series of simulations was conducted to assess the best choices for biogeochemical model parameters across the diverse regions, using a variety of validation data sets including satellite ocean colour (surface chlorophyll and particulate organic carbon, integrated primary production), surface underway pCO2, and depth profiles of oxygen and nitrate concentration from ships and Argo floats. An extensive set of parameter sensitivity experiments was conducted which are documented in detail here, with a focus on zooplankton grazing…
