在基于海洋大气环流模型的碳循环模型中，除了下降的颗粒有机碳外，还通过溶解有机碳的平流模拟了与新生产相关的有机碳通量。参与碳循环的化学物种的模型预测与观测进行了比较。相对于一个模型，其中新的生产只进行下降的颗粒有机碳，有显着更好的协议之间的预测和观察到的海洋磷酸盐和氧气浓度，如果新的生产通量的很大一部分是由溶解的有机碳。
The flux of organic carbon associated with new production has been modeled by advection of dissolved organic carbon in addition to falling particulate organic carbon, in a carbon cycle model that is based on an oceanic general circulation model. Model predictions of chemical species involved in the carbon cycle are compared with observations. Relative to a model in which new production is carried only by falling particulate organic carbon, there is significantly better agreement between predicted and observed oceanic phosphate and oxygen concentrations if a large part of the new production flux is carried by dissolved organic carbon.
