Dissolved inorganic nitrate, nitrite, silicate and phosphate concentrations of seawater sampled during the Antarctic Circumnavigation Expedition (ACE) during the Austral Summer of 2016/2017.

<strong>Dataset abstract</strong> This dataset contains dissolved inorganic nitrate, nitrite, silicate and phosphate concentrations of seawater sampled during the Antarctic Circumnavigation Expedition (ACE) Legs 1-3. Water samples were collected from the underway seawater supply every 3 hours, preserved and analysed for dissolved inorganic nutrient concentrations using flow injection and colorimetric methods. These samples provide an estimate of the dissolved concentrations of inorganic macronutrients essential for phytoplankton growth. <strong>Dataset contents</strong> README.txt, metadata, text data_file_header.txt, metadata, text ace_uw_nutrients_20200527CURRSGCMR.csv, data file, comma-separated values<strong>数据集摘要</strong> 本数据集收录了南极环极航行考察（Antarctic Circumnavigation Expedition, ACE）第1至3航次采集的海水样品中溶解态无机硝酸盐、亚硝酸盐、硅酸盐及磷酸盐浓度数据。研究人员每3小时从走航海水供水系统采集海水样品，经固定处理后采用流动注射与比色法分析溶解态无机营养盐浓度。本数据集的样品可用于估算浮游植物生长所必需的无机大量营养盐的溶解态浓度。<strong>数据集内容</strong> README.txt、元数据(metadata)、文本文件data_file_header.txt、元数据、文本文件ace_uw_nutrients_20200527CURRSGCMR.csv、逗号分隔值数据文件
