Dataset for the responses of ammonium consumption to increased suspended particulate matter in a eutrophic estuary

This is a dataset for the responses of ammonium consumption to increased suspended particulate matter in the Jiulong River estuary in southern China. Using 15N-labeling experiments, we quantified ammonia oxidation (AO) and ammonium uptake (AU) in SPM addition experiments along the salinity gradient of the Jiulong River Estuary, a typically human-impacted eutrophic and turbid estuary in China.本数据集聚焦中国南部九龙江河口区域悬浮颗粒物（suspended particulate matter, SPM）浓度升高对铵态氮消耗的响应。研究团队依托15N标记实验，在该河口的盐度梯度下开展SPM添加实验，定量测定了氨氧化作用（ammonia oxidation, AO）与铵摄取（ammonium uptake, AU）过程。九龙江河口是中国典型受人类活动影响的富营养化浊河口。
