Physical oceanography during the cruise SO269 in South China Sea in August 2019, station SO269_85-1 (SCS25_01)@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月至9月期间，在南海北部由德国R/V索恩号科考船执行SO269航次所采集的131条CTD剖面数据，采集工作依托SOCLIS项目——"气候与人为压力下的南海自然实验室"开展。本次测量的参数涵盖温度、盐度、溶解氧、荧光值、浊度、海面辐照度（SPAR）、光合有效辐射（PAR）以及声速，所用设备包括Sea-Bird SBE 911 plus型CTD系统，搭配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 ECO-FLNTU(RT)D型荧光计。此外，研究人员还计算了氧饱和度、位温以及以海面为基准的西格玛θ（sigma-theta）参数。该131条CTD剖面分布于81个测站，其研究目的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。本数据集曾被用于研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（Pharmaceutical and Personal Care Products，简称PPCPs）的赋存状态与空间分布特征。
