Physical oceanography at CTD stations of RV Sonne cruise SO266

Oceanographic and biochemical data obtained during cruise SO266 from 15.10.2018 to 18.11.2018 from Kaohsiung (Taiwan) to Kaohsiung (Taiwan) . A Seabird CTD Model 9plus recorded oceanographic data. The CTD comprised conductivity, temperature, and pressure sensors as well as a SBE 43 oxygen sensor and a WET labs ECO FLNTURTD fluorometer and turbidity sensor. According to the manufacturers, the accuracy of the conductivity, temperature, pressure, and oxygen was ± 0.0003 S m-1, ± 0.0002 °C, ± 0.02%, and ± 2% of saturation, respectively. The difference between the two salinity and temperature sensors were 0.0069 and 0.0010 °C, respectively. The WETLabs FLNTU measured chlorophyll fluorescence (ChlF, λ excitation=470 nm, λ emission=695 nm) with a sensitivity of 0.025 µg l-1.本数据集涵盖2018年10月15日至2018年11月18日期间SO266航次的观测数据，该航次往返于中国台湾高雄至高雄，包含海洋学与生物化学两类观测资料。本次航次采用Seabird CTD Model 9plus型温盐深剖面仪（Conductivity Temperature Depth，简称CTD）采集海洋学数据，该系统集成了电导、温度、压力传感器，同时搭载SBE 43型溶氧传感器以及WET Labs品牌的ECO FLNTURTD荧光浊度传感器。根据厂商提供的技术参数，电导、温度、压力与溶氧的测量精度分别为±0.0003 S·m⁻¹、±0.0002 ℃、±0.02%以及±2%（饱和度百分比）。两台盐度传感器间的差值为0.0069，两台温度传感器间的差值为0.0010 ℃。WETLabs FLNTU可测量叶绿素荧光（ChlF，激发波长λ=470 nm，发射波长λ=695 nm），其检测灵敏度为0.025 µg·L⁻¹。
