Carbonate variables simulated by the pan-Arctic sea ice-ocean model with riverine biogeochemical impact

Carbonate variables simulated by the pan-Arctic sea ice-ocean model COCO & Arctic NEMURO-C are summarized. This dataset presents the monthly mean time series of the simulated total alkalinity (TA), dissolved inorganic carbon (DIC), aragonite saturation rate of calcium carbonate (omega), pH, partial pressure of seawater CO2 (pCO2), and air-sea CO2 exchange (flxCO2) for 1979-2018. The regional averages for 7 sub-regions (Beaufort Shelf, Chukchi Cap, Canada Basin, East Siberian Sea, Laptev Sea, Kara Sea, and Eurasian Basin) are summerized. To evaluate riverine biogeochemical impact, the results in four experiments are listed. The concentration of riverine water tracer is also included. This work was supported by the Arctic Challenge for Sustainability (ArCS) II project.
