Carbon dioxide (CO2) is the most important greenhouse gas contributing to global warming and climate change. Climate change is likely to have dramatic economic and environmental consequences for Australia. Knowledge and understanding of the complex carbon cycle is fundamental for predicting future atmospheric CO2 levels and managing climate change. The aim of the work proposed here is to quantify and improve our understanding of the oceans role in controlling atmospheric CO2 levels. This will be done by combining modeling and observational expertise among UNSW and CSIRO (Marine Research) researchers. Our work will be the first to assess the extent of which the Southern Ocean (and Australian waters) acts as a carbon sink. This will reduce modeling uncertainties in predicting future atmospheric CO2 levels and will also be valuable to the federal government in future international negotiations on climate change.

二氧化碳 (CO2) 是导致全球变暖和气候变化的最重要的温室气体。 气候变化可能会给澳大利亚带来巨大的经济和环境后果。 了解和理解复杂的碳循环对于预测未来大气二氧化碳水平和管理气候变化至关重要。这里提出的工作的目的是量化和提高我们对海洋在控制大气二氧化碳水平方面的作用的理解。 这将通过结合新南威尔士大学和 CSIRO（海洋研究）研究人员的建模和观测专业知识来完成。 我们的工作将首先评估南大洋（和澳大利亚水域）作为碳汇的程度。 这将减少预测未来大气二氧化碳水平的建模不确定性，并且对联邦政府在未来气候变化国际谈判中也很有价值。
