深海生态系统的几个基本特征可以概括为：(1)深海是一个地球化学的汇；(2)深海的生物量在1000 m以下迅速下降；(3)深海物种丰富度在1000 m左右达到最大值。然而，我们对深海浮游生物和微浮游生物的认识仍然是不完整和不足的。关于在深海处理二氧化碳的可行性，目前，在做出任何分类决定之前，需要更详细地研究在实际静水压力下降低pH值和提高CO2分压对浮游动物和微浮游动物整个生命周期的潜在影响。考虑到CO2排放的可能性和必要时CO2回收的可能性，在深度大于3000米的海底受限凹陷中限制CO2的释放将比在水中分散更好。
Several general features of the deep-sea ecosystem can be summarized as: (1) the deep sea is a geochemical sink, (2) biomass declines rapidly with depth below 1000 m, and (3) species richness increases to a maximum at about 1000 m depth for pelagic species. Our knowledge of deep-sea plankton and micronekton is, however, still patchy and insufficient. In concern with the feasibility of CO2 disposal in the deep sea, at present, prior to any categorical decisions being made, more de tailed research is needed on the potential effects of lowered pH and raised partial pressure of CO2 over the entire life of zooplankton and micronekton under realistic hydrostatic pressures. Considering the possibility of CO2 discharge and of CO2 re trieval if necessary, confined release of CO2 in restricted depression of the seafloor at depths greater than 3000 m will be better than dispersion in midwater.
