Monitoring, modeling, and forecasting long-term changes in coastal seawater quality due to climate change
Summary
This study used an 8-year dataset from a coastal offshore area to model water quality changes over the next 80 years under climate change scenarios. The results predict that rising CO2-related ocean chemistry changes will progressively displace trace elements important for marine life, highlighting compound risks from climate change and chemical pollution in coastal waters.
Abstract After experiencing a period of maximum pollution, the water quality in the coastal zone may be at risk of further pollution due to the influence of climate change. We utilized an 8-year dataset to make predictions about the changes in water quality in this offshore area over the next 80 years. The simulation results indicate that as a result of the continuous increase in CO32–/OH–, trace elements will be displaced by calcium and magnesium, leading to re-suspension in the water. Additionally, indicators such as B/C, C/N, and C/P, which reflect the tolerance of water bodies towards eutrophication, gradually decreased. This suggests that in the future, the ocean will experience aqueous solution properties of high sea surface temperatures, eutrophication, carbon scarcity, and electron donor abundance. This change in matter group is irreversible and difficult to repair.
