Physical oceanography during the cruise SO269 in South China Sea in August 2019, station SO269_170-1 (SCS54)@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.本数据集包含2019年8至9月，在"气候与人为胁迫下的南海自然实验室"（SOCLIS）项目支持下，由德国"松涅"号（R/V Sonne）科考船SO269航次于南海北部海域获取的131条温盐深剖面（CTD）。本次观测使用Sea-Bird SBE 911 plus型温盐深剖面仪（CTD），配套SBE 43型溶解氧传感器、Biospherical公司QCP-2350 + QSR-2200型光合有效辐射（PAR）传感器以及WET Labs ECO-FLNTU(RT)D型荧光计，同步获取了温度、盐度、溶解氧、荧光强度、浊度、海面辐照度（SPAR）、光合有效辐射（PAR）和声速共8类参数的剖面数据。此外，研究团队还计算了溶解氧饱和度、位温以及以海面为基准的西格玛θ（sigma-theta）参数。该131条CTD剖面覆盖81个测站，旨在研究珠江口周边日益加剧的人为压力对南海北部陆架乃至深海海域的影响。本数据集曾用于探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、药物及个人护理品（PPCPs）的赋存情况与空间分布规律。
