ECOSCOPA network : high frequency environmental database

based on the consolidation of the ifremer networks resco (https://doi.org/10.17882/53007) and velyger (https://doi.org/10.17882/41888), the general objective of the ecoscopa project is to analyze the causes of spatio-temporal variability of the main life traits (larval stage - recruitment - reproduction - growth – survival – cytogenetic anomalies) of the pacific oyster in france and follow their evolution over the long term in the context of climate change.the high frequency environmental data are monitored since 2010 at several stations next to oyster farm areas in eight bays of the french coast (from south to north): thau lagoon and bays of arcachon, marennes oléron, bourgneuf, vilaine, brest, mont saint-michel and veys (see map below). sea temperature and practical salinity are recorded at 15-mins frequency. for several sites, fluorescence and turbidity data are also available.data are acquired with automatic probes directly put in oyster bags or fixed on metallic structure at 50 cm over the sediment bottom, except for thau lagoon whose probes are deployed at 2m below sea surface. since 2010, several types of probes were used: stp2, stps, smatch or wisens ctd from nke (www.nke-instrumentation.fr) and recently eco flntu (www.seabird.com). the probes are regularly qualified by calibrations in the ifremer coastal laboratories.precision estimated of the complete data collection process is: temperature (±0.1°c), salinity (±0.5psu), in vivo fluorescence (±10%), turbidity (±10%). the data are qualified into several levels: 0-no quality check performed, 1-good data, 2-probably good data, 3-probably bad data, 4-bad data, 5-value changed, 7-nominal value, 8-interpolated value, 9-missing value.

基于综合法国海洋研究所（Ifremer）网络Resco（https://doi.org/10.17882/53007）和Velyger（https://doi.org/10.17882/41888）的数据，Ecoscopa项目的总体目标在于分析法国太平洋牡蛎主要生命特征（幼虫阶段、补充、繁殖、生长、存活以及染色体异常）的时空变异性，并长期追踪其在气候变化背景下的演变过程。自2010年起，在高频环境数据的监测下，多个站点位于牡蛎养殖区域附近的海湾（自南至北依次为）：图阿湾和阿尔卡松湾、马雷讷奥尔隆、布荣、维兰、布斯特、蒙圣米歇尔以及韦斯（详见下述地图）。海水温度和实际盐度以15分钟为频率进行记录。对于多个站点，还提供了荧光和浊度数据。数据通过将自动探头直接放置于牡蛎袋中或固定在距沉积物底部50厘米的金属结构上获取，而图阿湾的探头则部署在海面下方2米处。自2010年以来，已使用多种类型的探头：NKE（www.nke-instrumentation.fr）的STP2、STPS、SMATCH或Wisens CTD，以及近期使用的Seabird的Eco Flntu（www.seabird.com）。探头在Ifremer沿海实验室进行定期的校准以进行质量验证。整个数据收集过程的精度估计为：温度（±0.1°C）、盐度（±0.5psu）、活体荧光（±10%）、浊度（±10%）。数据被划分为多个质量级别：0-未进行质量检查，1-良好数据，2-可能良好数据，3-可能不良数据，4-不良数据，5-值已更改，7-名义值，8-插值值，9-缺失值。
