Monitoring of the physico-chemical composition of the Seine River based on the MeSeine network

In Europe, the management of freshwater ecosystem is governed by the Water Framework Directive (2000/60/CE) and its transposing legislation in France (2006-1772 of December 2006). The good ecological status of water are evaluated using a combination of several indicators such as biological and physico-chemical parameters. The Seine River crosses several important urbanized areas of France, including the Parisian conurbation (9 millions inhabitants). To ensure the good ecological status of the Seine River, the Greater Paris Conurbation Sanitation Authority (SIAAP), has constructed and operated the MeSeine network since 1990. MeSeine constitutes a tool for evaluating the quality of the Seine river and its tributaries (Marne, Oise) in terms of physico-chemistry, bacteriology, micro-contamination and faunal diversity. The MeSeine network extends along 125 km of the Seine River (from Choisy to Méricourt) and over 13 km along the Marne River (frome Champigny to Alfortville). It is structured around tree pillars: Real time monitoring of the physico-chemical composition of the Seine river using in situ sensor, in particular dissolved oxygen and temperature sensors Sampling and laboratory analysis campaigns to monitor watercourses quality and comply with the quality standards as defined by the Water Framework Directive (good ecological and chemical parameters) Biota monitoring to appreciate the diversity of fish populations, macro-invertebrates and diatoms. The aim of this work is to provide data on the physico-chemical quality of the Seine generated by the MeSeine observatory via the open platform Zenodo.欧洲淡水生态系统的管理遵循《水框架指令》（Water Framework Directive，2000/60/CE），法国则通过2006年12月颁布的第2006-1772号立法文件将该指令转化为国内法。水体的良好生态状态需通过多指标组合评估，涵盖生物学与理化参数。塞纳河途经法国多处重要城市化区域，其中包括拥有900万人口的巴黎都会区。为保障塞纳河的良好生态状态，巴黎都会区卫生管理局（Greater Paris Conurbation Sanitation Authority，SIAAP）自1990年起搭建并运营梅塞纳（MeSeine）监测网络。该网络可用于评估塞纳河及其支流马恩河（Marne）、瓦兹河（Oise）的水质，覆盖理化指标、细菌学、微污染物及动物群落多样性四大维度。监测网络沿塞纳河延伸125公里（从舒瓦西至梅里库尔），沿马恩河延伸超13公里（从尚皮尼至阿尔福特维尔）。该网络依托三大核心体系构建：一是利用原位传感器对塞纳河的理化组成开展实时监测，重点监测溶解氧与温度参数；二是实施采样与实验室分析计划，以监测河道水质并符合《水框架指令》规定的生态与化学参数质量标准；三是开展生物群落监测，以评估鱼类种群、大型无脊椎动物及硅藻的多样性。本数据集旨在通过开源平台Zenodo发布由梅塞纳观测站采集生成的塞纳河理化水质数据。
