Ocean Acidification in a Rapidly Increasing CO2 World

二氧化碳不仅是一种温室气体，而且正在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是如何影响海洋生物钙化的能力，并确定世界海洋吸收二氧化碳的速度。为了在南大洋的热带浅水和深海海洋生态系统中实现可持续的钙化，二氧化碳排放的临界阈值将受到新的限制。

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.
