PHYTOBS dataset - French National Service of Observation for Phytoplankton in coastal waters

the phytobs-network dataset includes long-term time series on marine microphytoplankton, since 1987, along the whole french metropolitan coast. microphytoplankton data cover microscopic taxonomic identifications and counts. the whole dataset is available, it includes 25 sampling locations. phytobs-network studies microphytoplankton diversity in the hydrological context along french coasts under gradients of anthropogenic pressures. phytobs-network allows to analyse the responses of phytoplankton communities to environmental changes, to assess the quality of the coastal environment through indicators, to define ecological niches, to detect variations in bloom phenology, and to support any scientific question by providing data. the phytobs-network provides the scientific community and stakeholders with validated and qualified data, in order to improve knowledge regarding biomass, abundance and composition of marine microphytoplankton in coastal and lagoon waters in their hydrological context. phytobs-network originates of two networks. the historical rephy (french observation and monitoring program for phytoplankton and hydrology in coastal waters) supported by ifremer since 1984 and the somlit (service d'observation en milieu littoral) supported by insu-cnrs since 1995. the monitoring has started in 1987 on some sites and later in others. hydrological data are provided by rephy or somlit network as a function of site locations.

Phytobs-network 数据集收录了自1987年以来沿法国本土海岸的海洋微型浮游植物长期时间序列数据。该数据集涵盖了微型浮游植物的微观分类鉴定和计数。整个数据集完全开放，包含25个采样地点。Phytobs-network 研究了在法国海岸水文学背景下，微型浮游植物多样性在人为压力梯度下的变化。Phytobs-network 允许分析浮游植物群落对环境变化的响应，通过指标评估海岸环境质量，定义生态位，检测水华物候变化，并支持通过提供数据来解答任何科学问题。Phytobs-network 为科学界和利益相关者提供了经过验证和认证的数据，以提升对沿海和潟湖水域中海洋微型浮游植物的生物量、丰度和组成在相应水文学背景下的认知。Phytobs-network 起源于两个网络：自1984年起由ifremer支持的、针对沿海水域浮游植物和水文观测与监测的历史性Rephy项目，以及自1995年起由insu-cnrs支持的Somlit（沿海环境观测服务）。监测自1987年起在一些地点开始，后来扩展到其他地点。水文数据由Rephy或Somlit网络根据地点位置提供。
