UPTAKE OF ATMOSPHERIC CO2 IN THE OCEANS AND IMPLICATIONS FOR GLOBAL CHANGE: NEW PROXY DEVELOPMENTS

该项目的目的是量化海洋对人类活动产生的大气二氧化碳增加的反应。为此，将利用新开发的深海沉积物、珊瑚和珊瑚海绵中的古海洋学指标。 这些将用于评估海水酸度的变化以及海洋对过去大气CO2变化的反应。将确定海洋缓冲大气中二氧化碳上升的能力和作用。这将限制海水酸度增加对大堡礁等珊瑚礁的影响。

This project aims to quantify the response of the oceans to increasing atmospheric CO2 from anthropogenic production. This will be achieved by using newly developed paleoceanographic indicators in deep sea sediments, corals and coralline sponges. These will be used to evaluate changes in seawater acidity and the response of the oceans to past variations in atmospheric CO2. The capacity and role of the oceans to buffer the rise of atmospheric of CO2 will be ascertained. This will provide constraints on the impact of increased seawater acidity on coral reefs such as the Great Barrier Reef.
