Physical oceanography during the cruise SO269 in South China Sea in August 2019, station SO269_63-1-1 (SCS41)@en

This dataset provides 131 CTD profiles measured on board of the German R/V Sonne (cruise SO269) in the northern South China Sea, under the project SOCLIS – South China Sea Natural Laboratory under Climatic and Anthropogenic Stress, in August and September 2019. The 131 profiles of temperature, salinity, dissolved oxygen, fluorescence, turbidity, surface irradiance (SPAR) and Photosynthetically active radiation (PAR), and sound velocity were measured using a CTD Sea-Bird SBE 911 plus, together with oxygen sensor (SBE 43), PAR sensor (Biospherical, QCP-2350 + QSR-2200), and a fluorometer (WET Labs ECO-FLNTU(RT)D). Additionally, oxygen saturation, potential temperature and sigma-theta (with reference to the surface) were calculated. The 131 CTD profiles are distributed by 81 stations and aim to study the impact of a growing anthropogenic pressure around the Pearl River Estuary into the northern shelf of the South China Sea towards the deep sea. The dataset was used to study the presence and spatial distribution of natural and synthetic estrogenic compounds and pharmaceutical and personal care products (PPCPs) in the Pearl River Estuary and northern shelf of the South China Sea.本数据集收录了2019年8月至9月期间，德国“松恩号”（R/V Sonne）科考船第SO269航次在南海北部采集的131条CTD（Conductivity-Temperature-Depth，电导-温度-深度）剖面数据，相关野外作业隶属于SOCLIS项目——“气候与人为胁迫下的南海天然实验室”（South China Sea Natural Laboratory under Climatic and Anthropogenic Stress）。本次测量采用Sea-Bird SBE 911 plus型CTD系统，配套搭载SBE 43型溶解氧传感器、Biospherical公司QCP-2350 + QSR-2200型PAR（Photosynthetically Active Radiation，光合有效辐射）传感器，以及WET Labs ECO-FLNTU(RT)D型荧光浊度计，获取了温度、盐度、溶解氧、荧光强度、浊度、表面辐照度（SPAR）、光合有效辐射与声速共8项参数的剖面数据。此外，研究人员还计算得到了氧饱和度、位温以及以海面为参考基准的西格玛θ（sigma-theta）参数。该131条CTD剖面分布于81个采样站位，旨在探究珠江口周边日益加剧的人为压力对南海北部陆架延伸至深海区域的影响。本数据集曾被用于研究珠江口及南海北部陆架海域中天然与合成雌激素类化合物、药物和个人护理品（PPCPs，Pharmaceutical and Personal Care Products）的赋存状态与空间分布特征。
