中国第9次北极科学考察(2018年)海水酸碱度(pH)调查数据

酸碱度描述的是水溶液酸碱性强弱程度，用符号pH来表示。海水pH值是研究二氧化碳体系时易于直接测定的最重要的物理量之一，大洋海水的pH值主要由海水中的碳酸盐体系控制，也受温度、盐度和压力等因素的影响。
2018年中国第9次北极科学考察期间，开展了重点海域海水分水层酸碱度(pH)的调查。本数据包括总计76个站(次)的海水酸碱度(pH)分水层数据，水深范围为3-3800m。

pH is a metric that quantifies the acidity or alkalinity of an aqueous solution. Seawater pH is one of the most important physical parameters that can be easily measured directly when studying the marine carbon dioxide system. The pH of open-ocean seawater is primarily controlled by the carbonate system in seawater, and also influenced by factors such as temperature, salinity and pressure. During the 9th Chinese National Arctic Research Expedition in 2018, a survey on layer-resolved seawater pH in key marine regions was conducted. This dataset includes layer-resolved seawater pH data from a total of 76 stations (casts), with water depths ranging from 3 m to 3800 m.
