Simulated NPP considering changes in atmospheric CO2, of the physical climate, and of land-derived nutrient inputs in a global ocean biogeochemistry model

we performed a series of global ocean biogeochemistry model simulations over 1905 to 2010 taking into account 1. changes in atmospheric co2, 2. changes in atmospheric co2 and changes in the physical climate, and 3. hanges in atmospheric co2,changes in the physical climate, as well as changes in land-derived inputs of p and n, including both riverine & atmospheric deposition perturbations. these simulations can be used to isolate for the individual effects on the marine carbon cycle arising from pertubations of atmospheric co2, of the physical climate, and of land-derived nutrient inputs. the simulations were performed in the max-planck-institute ocean model (mpi-om) tp04 configuration, which resolves the global ocean at a resolution of around 0.4 degrees, coupled an enhanced version of the ocean biogeochemistry model hamocc for a better representation of processes taking place in the coastal ocean.

本研究在 1905 年至 2010 年期间对全球海洋生物地球化学模型进行了系列模拟实验，充分考虑了以下因素：1. 大气二氧化碳浓度的变化；2. 大气二氧化碳浓度变化与物理气候的变化；3. 大气二氧化碳浓度、物理气候变化以及陆地来源的磷和氮输入变化，包括河流沉积和大气沉降的扰动。这些模拟实验可用于分离大气二氧化碳扰动、物理气候变化和陆地营养输入变化对海洋碳循环的个体影响。模拟实验采用马克斯·普朗克研究所海洋模型（Max-Planck-Institute Ocean Model，简称 MPI-OM）TP04 配置进行，该配置以约 0.4 度的分辨率解析全球海洋，并耦合了改进版本的海洋生物地球化学模型 HAMOCC，以更精确地描述近海地区的生物地球化学过程。
