中国第10次北极科学考察(2019年)海水溶解氧(DO)分析数据

海水溶解氧（DO）是指溶解在海水中的氧气的浓度，是海水中光合作用、呼吸作用和其他生地化过程综合作用的结果，表征海水含氧量。对极区海水溶解氧开展调查，对于了解氧气的分布、消耗补偿情况，了解极地特定海区生地化过程、研究其对生态系统的作用具有重要意义。
2019年中国第10次北极科学考察期间，开展北极重点海域海水分水层溶解氧（DO）调查。本数据包括总计49个站的海水溶解氧(DO)分水层数据，水深最深达2000m。

Dissolved Oxygen (DO) in seawater refers to the concentration of oxygen dissolved in seawater. It is the product of the combined effects of photosynthesis, respiration and other biogeochemical processes in marine environments, and serves as an indicator of seawater oxygen content. Investigations on dissolved oxygen in polar seawater are of great significance for understanding the distribution, consumption and compensation of oxygen, as well as the biogeochemical processes in specific polar sea areas and their impacts on marine ecosystems. During the 10th Chinese National Arctic Scientific Expedition in 2019, a survey of dissolved oxygen (DO) in water column layers of key Arctic sea areas was conducted. This dataset contains dissolved oxygen (DO) data from water column layers at a total of 49 stations, with the maximum surveyed water depth reaching 2000 meters.
