Ocean Alkalinity Enhancement in deep water formation regions under low and high emission pathways

The dataset includes the minimum data required to reproduce the findings of Nagwekar et al. (2024). The output of the global ocean biogeochemical model FESOM2.1-REcoM3 implementing Ocean Alkalinity Enhancement (OAE) is provided. In particular it contains: a) model grid, b)Water Mass Transformation and Formation rates in the subduction regions of the Southern Ocean (SO), Northwest Atlantic (NWA) and Norwegian-Barents Sea (NBS) region, c) annual mean time-series (2015-2100) for the increase in oceanic CO2 uptake, long-term and short-term OAE efficiencies, surface alkalinity, depth and area integrated Dissolved Inorganic carbon (DIC), diatom productivity, small phytoplankton productivity, and total Net Primary Production (NPP), d) seasonal time-series averaged over 2090-2099 for the increase in oceanic CO2 uptake, mixed layer depth, amount of olivine added, surface alkalinity, DIC accumulation, and total NPP for the subduction regions in the SO, NWA, NBS, and e) data for spatial maps averaged over 2090-2099 for oceanic CO2 uptake, alkalinity, calcification and NPP. The data is available for the SSP1-2.6 and SSP3-7.0 emission sceanrio.
