Influence of air-sea CO2 disequilibrium on biological carbon pump sequestration inventories and timescales

This dataset provides output from carbon sequestration calculations presented in the following paper: Nowicki, M., DeVries, T., &amp; Siegel, D. A. (2024). The influence of air-sea CO2 disequilibrium on carbon sequestration by the ocean's biological carbon pump. <i>Global Biogeochemical Cycles</i>.The dataset provides dissolved inorganic carbon (DIC) concentrations computed using the full nonlinear and linearized models under both instantaneous and realistic gas exchange scenarios, as described in the above referenced paper. The average sequestration times under both gas exchange scenarios are also included, as well as the air-sea CO2 equilibration timescale and biological DIC flux (referred to as Jbio in the paper) vectors used in all of these computations. The dataset also provides the fraction of biogenic DIC sequestered for 0-1000 years under both gas exchange scenarios, referred to as f(x,t) in Equation 9 and used to create Figure 5 in the above referenced paper. This dataset only includes years 0-1000 of the 7000 year simulation shown in Figure 5. Longer simulations can be obtained by contacting the author. Also included is a MATLAB script with examples for creating some of the figures. The script loads in the dataset and extracts the relevant variables for computing the DIC inventories shown in Table 2, as well as for creating Figures 1-5. If using this dataset, please cite the original publication of Nowicki et al. (2024).

本数据集提供了下述论文中刊载的海洋固碳量计算结果：Nowicki, M.、DeVries, T. 与 Siegel, D. A.（2024）所著《海-气CO₂不平衡对海洋生物碳泵固碳作用的影响》，发表于《全球生物地球化学循环》（Global Biogeochemical Cycles）。

本数据集包含了在瞬时气体交换与现实气体交换两种场景下，采用全非线性模型与线性化模型计算得到的溶解无机碳（dissolved inorganic carbon, DIC）浓度，具体细节详见上述参考文献中的描述。同时本数据集还提供了两种气体交换场景下的平均固碳时长、海-气CO₂平衡时间尺度，以及所有上述计算过程所采用的生物源溶解无机碳通量（论文中记为J_bio）向量。

此外，本数据集还提供了两种气体交换场景下，0至1000年时段内生物源溶解无机碳的固存份额——即上述参考文献中公式9所定义的f(x,t)，该数据用于生成参考文献中的图5。本数据集仅包含参考文献中图5所示的7000年模拟结果中的0至1000年时段，如需获取更长时长的模拟结果，请联系数据集作者。

本数据集还附带一份MATLAB脚本，内含部分图表绘制示例。该脚本可加载数据集，并提取相关变量以计算表2所示的溶解无机碳储量，同时可用于生成图1至图5。
