SPI - Nutrient concentration in seawater samples, collected from the underway supply, CTD and trace metal rosettes in the Southern Ocean during the austral summer of 2016/2017, on board the Antarctic Circumnavigation Expedition (ACE).

This dataset presents concentrations of nutrients (µmol/L): nitrous oxide (NOx), nitrate, nitrite, ammonium (NH4), phosphate (PO4) and silicic acid (Si), measured in samples of seawater during the Antarctic Circumnavigation Expedition (ACE). Samples were collected from CTD and trace metal rosette (TMR) deployments, as well as from the underway water supply on board, then analysed by flow injection following certified standards. This data was collected to support physical, chemical and biological oceanography studies in the Southern Ocean, conducted as part of ACE during the austral summer of 2016/2017.

本数据集展示了南极环绕航行考察（ACE）期间，从海水样本中测得的营养物质浓度（单位：微摩尔/升），包括一氧化二氮（NOx）、硝酸盐、亚硝酸盐、铵（NH4）、磷酸盐（PO4）和硅酸（Si）。这些样本分别采集自CTD和微量元素玫瑰瓶（TMR）的部署，以及船上的实时水质供应，随后按照认证标准进行流动注射分析。收集这些数据旨在支持南极夏季2016/2017年期间作为ACE一部分进行的物理、化学和生物海洋学研究。
