Saline coastal wetlands store large amounts of carbon and are potentially the most efficient sinks of carbon amongst natural ecosystems. This project will use isotopic tracers to quantify carbon retention within saline coastal wetlands in southeastern Australia, establish the vulnerability of these wetlands to sea-level rise using estimates of sediment accretion and surface elevation change, and use this information to predict the distribution of saline coastal wetlands and estimate the carbon sequestration potential of coastal wetlands within a ‘low-carbon economy’. This project will remove impediments to the proper economic evaluation of saline coastal wetlands and enable restoration coastal wetlands to be used to offset carbon emissions.

滨海湿地储存了大量的碳，是自然生态系统中最有效的碳汇。该项目将使用同位素示踪剂来量化澳大利亚东南部沿海盐碱湿地的碳保留，使用沉积物增加和表面高程变化的估计来确定这些湿地对海平面上升的脆弱性，并使用这些信息来预测沿海盐碱湿地的分布，并估计沿海湿地在“低碳经济”中的碳固存潜力。该项目将消除对含盐沿海湿地进行适当经济评估的障碍，并使沿海湿地的恢复能够用于抵消碳排放。
