Porewater chemistry from site NB8 in the Ore Estuary (Bothnian Sea)

Porewater depth profiles of ammonium, nitrate, sulfate, sulfide, dissolved iron, dissolved manganese, methane and oxygen; Solid phase depth profiles of total organic carbon, sequential iron and manganese extraction results of site NB8 in the Ore Estuary in the Bothnian Sea. (data published in doi:10.1021/acs.est.3c02023). Porewater ammonium and nitrate concentrations were determined colorimetrically using the indophenol-blue method and with a Gallery Automated Chemistry Analyzer type, respectively.

波腾海奥雷湾口NB8地点的孔隙水深度剖面，包括铵、硝酸盐、硫酸盐、硫化物、溶解铁、溶解锰、甲烷和氧的含量；以及固体相深度剖面，包含总有机碳、铁和锰的连续提取结果。相关数据已发表在《环境科学与技术》期刊（DOI: 10.1021/acs.est.3c02023）。孔隙水中的铵和硝酸盐浓度分别采用吲哚酚蓝比色法和自动化学分析仪法测定。
