中国第38次南极科学考察(2021-2022年)普里兹湾溶解氧（DO）分水层分析数据

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。
2021-2022年中国第38次南极科学考察期间，开展了普里兹湾重点海域海水分水层溶解氧（DO）调查。本数据包括总计8个站位的海水溶解氧(DO)分水层数据，水深范围为0-2000m。

Dissolved Oxygen (DO) in seawater is defined as the concentration of oxygen dissolved in seawater. It is generated through the combined effects of photosynthesis, respiration and other biogeochemical processes in marine environments, and serves as an indicator of seawater oxygen content. Investigations of seawater DO in polar regions are critically important for revealing the spatial distribution of oxygen, its consumption and compensation dynamics, as well as biogeochemical processes in specific polar marine areas and their impacts on marine ecosystems.
During the 38th Chinese National Antarctic Research Expedition conducted from 2021 to 2022, a targeted survey of dissolved oxygen (DO) in seawater column layers was implemented in key sea regions of Prydz Bay. This dataset encompasses DO data from seawater column layers at a total of 8 sampling stations, with the measured water depth ranging from 0 to 2000 meters.
