Calculated contributions of terrestrial plant matter and phytoplankton matter to total organic matter in sediments assuming N/C end members of 0.04 (terr) and 0.13 (phyt).

本数据集基于氮碳（N/C）端元假设，设定陆生端元（terr）取值0.04、浮游植物端元（phyt）取值0.13，计算得到了陆生植物源有机质（terrestrial plant matter）与浮游植物源有机质（phytoplankton matter）对沉积物（sediments）中总有机质（total organic matter）的贡献占比。
