Through a comprehensive, large-scale sampling campaign of sediment Blue Carbon in tidal marshes, mangroves, and seagrasses in a data-deficient region of temperate southeast Australia, this study contributed to the growing global inventory of blue carbon sinks. 

This program sampled over 100 blue carbon ecosystems across the Victorian coastline (southeast Australia) to quantify total sediment stocks, variability across spatial scales, and estimate emissions associated with historical ecosystem loss. This study was among the first to present a comprehensive comparison of sediment stocks across and within coastal blue carbon ecosystems. We estimate substantial and valuable carbon stocks associated with these ecosystems that have suffered considerable losses in the past and need protection into the future to maintain their role as carbon sinks.
