人类向大气中添加的二氧化碳正在产生一连串的化学后果，最终将延伸到世界上所有海洋的底部。记录最充分的海水效应包括全球范围内开阔海洋酸度的增加和碳酸钙饱和状态的大规模下降。一些年轻的、快速生长的钙质生物对不利影响的易感性突出了潜在的生物和经济后果。海水二氧化碳化学的许多重要方面目前只能间接观察到，重要但难以观察到的变化包括物种形成的变化和一些生命必需元素可能的生物可利用性。迫切需要创新和发明来开发记录这个海洋快速演变时代所需的现场仪器。
Human additions of carbon dioxide to the atmosphere are creating a cascade of chemical consequences that will eventually extend to the bottom of all the world's oceans. Among the best-documented seawater effects are a worldwide increase in open-ocean acidity and large-scale declines in calcium carbonate saturation states. The susceptibility of some young, fast-growing calcareous organisms to adverse impacts highlights the potential for biological and economic consequences. Many important aspects of seawater CO2 chemistry can be only indirectly observed at present, and important but difficult-to-observe changes can include shifts in the speciation and possibly bioavailability of some life-essential elements. Innovation and invention are urgently needed to develop the in situ instrumentation required to document this era of rapid ocean evolution.
