土壤在化学风化反应和碳从陆地到海洋的转移中起着重要的作用。作为防止气候变化的一种手段，通过“加强风化”来增加碱度对海洋的贡献的提议正受到越来越多的关注。这将加强土壤的生物地球化学功能与海洋碱度水平之间的现有联系。增强风化的可行性取决于土壤中添加了什么矿物，土壤中次生矿物的形成和排水制度，以及溶解矿物周围呼吸的二氧化碳分压的综合影响。通过加强风化来提高海洋中的碱度水平，可以从两个方面帮助改善海洋酸化的影响。首先，风化作用的加强会略微提高排水水域和沿岸水域的酸碱度。PH升高将导致碳酸盐矿物饱和度的增加，并部分逆转二氧化碳升高的影响。其次，碱度的增加将有助于通过保持‘翻滚系数’来补充海洋的缓冲能力，使海洋对进一步的二氧化碳排放更具弹性。然而，关于加强风化对下游和海洋影响的研究有限，作为部署决策的基础。这篇文章是《土壤在向人类提供自然贡献中的作用》主题的一部分。
Soils play an important role in mediating chemical weathering reactions and carbon transfer from the land to the ocean. Proposals to increase the contribution of alkalinity to the oceans through ‘enhanced weathering’ as a means to help prevent climate change are gaining increasing attention. This would augment the existing connection between the biogeochemical function of soils and alkalinity levels in the ocean. The feasibility of enhanced weathering depends on the combined influence of what minerals are added to soils, the formation of secondary minerals in soils and the drainage regime, and the partial pressure of respired CO2 around the dissolving mineral. Increasing the alkalinity levels in the ocean through enhanced weathering could help to ameliorate the effects of ocean acidification in two ways. First, enhanced weathering would slightly elevate the pH of drainage waters, and the receiving coastal waters. The elevated pH would result in an increase in carbonate mineral saturation states, and a partial reversal in the effects of elevated CO2. Second, the increase in alkalinity would help to replenish the ocean's buffering capacity by maintaining the ‘Revelle Factor’, making the oceans more resilient to further CO2 emissions. However, there is limited research on the downstream and oceanic impacts of enhanced weathering on which to base deployment decisions. This article is part of the theme issue ‘The role of soils in delivering Nature's Contributions to People’.
