| الوصف: | The seasonal cycle represents one of the largest signals of dissolved inorganic carbon (DIC) in the ocean, yet these seasonal variations are not well established at a global scale. Here, we present the Mapped Observation‐Based Oceanic DIC (MOBO‐DIC) product, a monthly DIC climatology developed based on the DIC measurements from GLODAPv2.2019 and a two‐step neural network method to interpolate and map the measurements. MOBO‐DIC extends from the surface down to 2,000 m and from 65°N to 65°S. We find the largest seasonal amplitudes of surface DIC in the northern high‐latitude Pacific (∼30 to >50 μmol kg−1). Surface DIC maxima occur in hemispheric spring and minima in fall, driven by the input of DIC into the upper ocean by mixing during winter, and net community production (NCP) driven drawdown of DIC over summer. The seasonal pattern seen at the surface extends to a nodal depth of Key Points We present a near‐global monthly DIC climatology (MOBO‐DIC) based on ship observations and a two‐step neural network Seasonal surface DIC amplitudes range from 0 to more than 50 μmol kg−1 MOBO‐DIC yields a spring‐to‐fall NCP in the euphotic zone of the mid‐latitudes of 3.9 ± 2.7 Pg C yr−1 European Community's Horizon 2020 Project International Max Planck Research School on Earth System Modelling (IMPRS‐ESM) |
