Hypoxic bottom waters as a carbon source to atmosphere during a typhoon passage over the East China Sea

The dataset includes a time series mooring record (3–20 July, 2015), collected in the East China Sea shelf (122.8°E, 30.6°N), and cruise results in the shelf . The mooring system recorded surface salinity, sea surface temperature, bottom temperature, surface pCO2, dissolved oxygen, Chl a, and wind speed. It shows the variations of pCO2 and other biogeochemical parameters during typhoon Chan-hom in the East China Sea shelf in 2015. The surface temperature, salinity, dissolved oxygen, and Chl a were obtained using Water Quality Monitor. The pCO2 data were collected using SAMI pCO2 (Sunburst sensor). The bottom temperature were measured using RBR. The wind speed data were collected using Young. The cruise results show Chl a profiles before and after typhoon Chan-hom in 2015 at mooring site, and bottom pCO2 in 2017 in the East China Sea shelf .

本数据集包含2015年7月3日至20日在东海陆架（122.8°E，30.6°N）获取的时间序列锚定观测记录，以及该海域的航次调查成果。该锚定观测系统同步记录了表层盐度、海表温度、底层温度、表层海水二氧化碳分压（pCO2）、溶解氧、叶绿素a（Chl a）以及风速等参数，完整展现了2015年台风灿鸿（Chan-hom）过境东海陆架期间，表层海水二氧化碳分压及其他生物地球化学参数的动态变化过程。其中表层温度、盐度、溶解氧及叶绿素a数据通过水质监测仪（Water Quality Monitor）获取；表层海水二氧化碳分压数据采用SAMI pCO2（Sunburst传感器）采集；底层温度由RBR设备测得；风速数据由Young设备采集。本次航次调查成果还包含2015年台风灿鸿过境锚定站点前后的叶绿素a垂直剖面数据，以及2017年东海陆架的底层海水二氧化碳分压观测数据。
