Dissolved cobalt and manganese in the East China Sea

this dataset describes the dissolved cobalt and manganese distributions in the east china sea. other parameters such as salinity, water temperature, potential density, dissolved oxygen, and nutrient (nitrate, phosphate, and silicate) concentrations are also included. seawater samples used for generating this dataset were obtained during the ks-15-6 cruise onboard r/v shinsei maru between july and august 2015 (stn1 to stn15), and during the kh-15-3 cruise onboard r/v hakuho maru in october 2015 (f1, d4, b8, and i1). dissolved cobalt concentrations were determined using cathodic stripping voltammetry at the university of tokyo and by using inductively coupled plasma - mass spectrometry (icp-ms) at kanazawa university, japan. meanwhile, dissolved manganese concentrations were determined using icp-ms at both the university of tokyo and kanazawa university. all samples were irradiated with ultraviolet light before analysis.

本数据集详尽描述了东海海域中溶解态钴和锰的分布情况。其中亦涵盖了诸如盐度、水温、密度潜能、溶解氧以及营养盐（硝酸盐、磷酸盐和硅酸盐）浓度等参数。用于构建本数据集的海洋水样系于2015年7月至8月间，在R/V深生丸号（Shinsei Maru）的KS-15-6航次期间采集（站点编号为STN1至STN15），以及同年10月在R/V白河丸号（Hakuho Maru）的KH-15-3航次期间采集（编号分别为F1、D4、B8和I1）。钴的溶解浓度通过东京大学的阴极溶出伏安法以及日本金泽大学的电感耦合等离子体质谱法（ICP-MS）测定。同时，锰的溶解浓度亦采用ICP-MS在东京大学和金泽大学进行测定。所有样品在分析前均经紫外线照射处理。
