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.

欧洲淡水生态系统管理遵循《水框架指令（Water Framework Directive, 2000/60/CE）》及其在法国的转化立法——2006年12月颁布的2006-1772号法令。水体良好生态状态的评估需结合多项指标，涵盖生物学与理化参数。塞纳河途经法国多个重要城市化区域，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，大巴黎都会区卫生管理局（Greater Paris Conurbation Sanitation Authority, SIAAP）自1990年起建设并运营了MeSeine监测网络。MeSeine是用于评估塞纳河及其支流（马恩河、瓦兹河）的理化特性、细菌学指标、微污染物含量及动物群落多样性的专业工具。

MeSeine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）。该网络围绕三大核心支柱构建：
1. 利用原位传感器（in situ sensor）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；
2. 开展采样与实验室分析工作，以监测河流水质并符合《水框架指令》规定的水质标准（良好生态与化学参数要求）；
3. 实施生物群落监测，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MeSeine观测站生成的塞纳河理化质量相关数据。
