Hypoxia observations in the East China Sea inner shelf in 2020

A cruise on board the R/V Runjiang I from 17 to 30 August 2020 was conducted to investigate hypoxia in 2020 over the East China Sea inner shelf. Six cross-shelf sections on the East China Sea shelf were surveyed in Leg 1 and an additional four sections were revisited in Leg 2. Water samples were collected using Niskin bottles mounted onto a Rosette sampling assembly. Biogeochemical data (nutrients, oxygen, dissolved inorganic carbon) was measured using instruments presented in Metadata file.

2020年8月17日至30日，科研团队搭乘“润江一号”科考船（R/V Runjiang I）执行航次，旨在调查2020年东海内陆架的水体低氧现象。第一航次期间共对东海陆架的6条跨陆架断面开展了调查，第二航次则重访了另外4条断面。本次研究采用搭载于罗塞特采水组合装置（Rosette sampling assembly）的尼斯金采水瓶（Niskin bottles）采集水样，营养盐、溶解氧、溶解无机碳等生物地球化学数据的测定工作，均使用元数据文件（Metadata file）中列明的仪器完成。
