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

海洋对大气中二氧化碳的吸收及其对全球变化的影响：新的代理发展。该项目旨在量化海洋对人为生产增加大气二氧化碳的反应。这将通过在深海沉积物、珊瑚和珊瑚海绵中使用新开发的古海洋学指标来实现。这些数据将用于评估海水酸度的变化以及海洋对过去大气二氧化碳变化的反应。海洋缓冲大气中二氧化碳上升的能力和作用将得到确定。这将限制海水酸度增加对大堡礁等珊瑚礁的影响。

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