We estimate preformed ocean phosphate, nitrate, oxygen, silicate, and alkalinity by combining a reconstruction of ventilation pathways in the ocean interior with estimates of submixed layer properties. These new preformed property estimates are intended to aid biogeochemical cycling studies and validation of modeled preformed property distributions and are available online. Analyses of net property accumulations (observed minus preformed properties) indicate net remineralization ratios in the ocean interior of [1 P]: [14.1 ± 0.6 N]: [−141 ± 12 O₂]: [95 ± 25 Si]: [89 ± 9 TA]. These ratios imply that the interior ocean stores 1,300 (±230) PgC through organic matter remineralization and 540 (±60) PgC through carbonate mineral dissolution and that apparent oxygen utilization can overestimate the interior ocean oxygen consumption by ~25%. Further, only 4 (±1%) and 46 (±5%) of the total alkalinity accumulated from carbonate mineral dissolution are found in seawater that is supersaturated with respect to the aragonite and calcite mineral forms of calcium carbonate, respectively. These small excess alkalinity inventories are due to smaller volumes of the supersaturated water masses and shorter ventilation timescales, as carbonate mineral dissolution rates appear nearly independent of depth and saturation state.

海洋有机物和碳酸盐矿物循环定量化的预制属性

我们通过结合重建海洋内部通风路径和估计混合层特性来估计预先形成的海洋磷酸盐，硝酸盐，氧气，硅酸盐和碱度。这些新的预制属性估算旨在帮助进行生物地球化学循环研究以及对建模的预制属性分布进行验证，并且可以在线获取。净特性积累（观察到的负性特性）的分析表明，[1 P]：[14.1±0.6 N]：[−141±12 O ₂ ]海洋内部的净再矿化率]：[95±25 Si]：[89±9TA]。这些比率意味着内部海洋通过有机物再矿化可存储1,300（±230）PgC，通过碳酸盐矿物溶解可存储540（±60）PgC，表观氧气利用率可高估内部海洋氧气消耗约25％。此外，在分别相对于文石和方解石矿物形式的碳酸钙而言过饱和的海水中，仅发现了碳酸盐矿物溶解累积的总碱度的4％（±1％）和46％（±5％）。这些少量的过剩碱度库存是由于过饱和水团的体积较小和通气时间尺度较短，因为碳酸盐矿物的溶解速率似乎几乎与深度和饱和状态无关。
