Carbonate sediment dissolution is a globally significant process, but poorly understood in shallow marine waters. This project will determine whether the combined effect of organic matter, ocean acidification and pore water flow in shallow water carbonate sediments increases the release of calcium and alkalinity to the ocean. This project is significant because this release has not previously been accounted for and may lead to an additional uptake of atmospheric carbon dioxide into the global ocean, maybe some additional buffering against ocean acidification, but unfortunately, maybe also a loss of carbonate ecosystems. The outcomes of this project will make a significant contribution to our understanding of the global carbon cycle.

碳酸盐沉积物溶解是一个全球性的重要过程，但在浅海沃茨了解甚少。该项目将确定有机物、海洋酸化和浅水碳酸盐沉积物中孔隙水流动的综合影响是否增加了钙和碱度向海洋的释放。这个项目意义重大，因为这种释放以前没有被考虑过，可能会导致大气二氧化碳额外吸收到全球海洋中，可能会对海洋酸化产生额外的缓冲，但不幸的是，也可能会失去碳酸盐生态系统。该项目的成果将为我们理解全球碳循环做出重大贡献。
