Di Qi, Liqi Chen. Review on Researches of Aragonite Saturation State in the Arctic Ocean: A Key Parameter of Arctic Ocean Acidification[J]. Advances in Earth Science, 2014, 29(5): 569-576.

:Aragonite saturation state (Ωarg) is a key parameter to assess the calcifying marine organisms’ impacts of ocean acidification. Oceans are becoming more acidic and lend to the decreased of the aragonite saturation state. The Arctic Ocean is an important part of the global ocean system with a unique larger continental shelve and rupit sea ice declineing. Model simulations have presented the Arctic Ocean are expected to become the first undersaturated (Ωarg <1) in deep oceans. However, there are still no enough adequate data to be gained due to geological politics and harsh environments. This paper attempts to summarize some?conclusion?and?implications?of?the?research, focused the spatial and temporal distributions of Ωarg and to discuss their driving factors, including sea-air CO2 exchange, sea ice melt, biological processes etc.. The tendency of Ωarg in the context of Arctic Ocean acidification and sea-ice retreat are also touched upon.
