Physical oceanography during the cruise SO269 in South China Sea in August 2019, station SO269_163-4-2 (SCS58_03)@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.本数据集涵盖2019年8月至9月期间，在南海北部执行的德国松内号（R/V Sonne）SO269航次所采集的131条温盐深剖面（CTD，Conductivity Temperature Depth）数据，相关野外工作隶属于项目SOCLIS——‘气候与人为压力下的南海自然实验室’（South China Sea Natural Laboratory under Climatic and Anthropogenic Stress）。本次测量共获取温度、盐度、溶解氧、荧光强度、浊度、海面辐照度（SPAR）、光合有效辐射（PAR）及声速共8类参数，所用观测设备包括Sea-Bird SBE 911 plus型CTD温盐深剖面仪、SBE 43型溶解氧传感器、Biospherical公司QCP-2350 + QSR-2200型PAR传感器，以及WET Labs公司ECO-FLNTU(RT)D型荧光计。此外，研究团队还计算得到溶解氧饱和度、位温以及以海面为基准的西格玛θ（sigma-theta）参数。本数据集包含的131条CTD剖面来自81个观测站位，其研究目标为解析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区域的影响。该数据集曾被用于探究珠江口及南海北部陆架区域内天然与合成雌激素类化合物、药物与个人护理品（PPCPs）的赋存状态与空间分布特征。
