Carbon dioxide not only acts as a greenhouse gas but is being dissolved at increasing rates into the surface waters of the world's oceans, causing ocean acidity. We will examine how the rapidly increasing trend towards acidity in the oceans surrounding Australia is effecting the ability of marine organisms to calcify and determine the rate at which the world's ocean sink for CO2 is being reduced. New constraints will be placed on the critical threshold limits of CO2 emissions for sustainable calcification in both shallow tropical and deep-water marine ecosystems of the Southern Oceans.

二氧化碳不仅是一种温室气体，而且正以越来越快的速度溶解到世界海洋的表层水中，导致海洋酸化。我们将研究澳大利亚周围海洋酸度迅速增加的趋势如何影响海洋生物的钙化能力，并确定世界海洋二氧化碳汇减少的速度。南大洋浅层热带和深水海洋生态系统可持续钙化的二氧化碳排放临界阈值将受到新的限制。
