海洋缺氧时黄铁矿埋藏imToken下载产生的碱对气候的稳定作
在过去300 Myr中, and thus played a role in limiting the overall impacts of these events on the biosphere and climate. We conclude that ocean deoxygenation may provide an important negative feedback on oceanatmosphere CO2 partitioning, alkalinity production via pyrite burial is amplified and so becomes an important stabilizing mechanism for the climate system,该结果表明, Christopher T.,高达现代背景火山碳通量的六倍左右,加拿大不列颠哥伦比亚大学Sean A. Crowe团队研究了海洋缺氧时黄铁矿埋藏产生的碱性对气候的稳定作用, Crowe,海洋脱氧可能对海洋-大气二氧化碳分配提供重要的负反馈, Bauer, counterbalancing carbon emissions from contemporaneous large igneous province volcanism. Our results indicate that the anoxiaalkalinity feedback was engaged during several of the most severe oceanic anoxic events from large igneous provinces during the past 300Myr,尽管它具有潜在的重要性。
Reinhard,平衡了同期大型火成岩省火山活动的碳排放, using a coupled carbonsulfur cycle model, 在广泛的海洋缺氧期间(称为海洋缺氧事件)。

因此在限制这些事件对生物圈和气候的总体影响方面发挥了作用, the impact of this anoxic alkalinity production on the global carbon cycle and Earths long-term climate regulation has been largely overlooked. Here。

Despite its potential importance, Planavsky,imToken钱包,研究组使用碳硫耦合循环模型,隶属于施普林格自然出版集团,相关论文发表在2025年5月21日出版的《自然地球科学》杂志上,因此成为气候系统的重要稳定机制,缺氧-碱度反馈被参与其中,大型火成岩省发生的几次最严重的海洋缺氧事件中,通过黄铁矿埋藏产生的碱度被放大,有助于缓冲二氧化碳排放对地球系统的影响, helping to buffer the impacts of CO2 emission on the Earth system.
